Canon PIXMA MP800 Error 6A00

I've owned my Canon PIXMA MP800 multifunction printer for about 2 weeks and today it is not printing. The error on the LCD of the printer is 6A00. Anyone know what this is about? I called Canon and they suggest I drive the machine to the nearest Canon approved repair center (which is 3 hours away) and have it looked at...so I am trying to avoid this if possible. Any advice would be greatly appreciated. Thanks.

I know this problem- The problem is inside the printer. Turn off the printer and open the replacement ink compartment- move the inks holder far to the left- use a torch to check where the inks holder home and you'll see that there is a sponge a tiny rectangular shape come loose -use the twiter and put back in place (holder). Hope this help

This did the trick. Thank you so much! - unknown
I have this code Error 6A00.
Several times i try to on/off the printer......change the position of the printing head.....the cartridges.....
Finnaly I find ..on the right (inside printer)...a small 1/4 cm rectangular "hard sponge" in a unusual place.
After another change of the position of the cartridges.... finnaly IT WORKS
BUT I DON'T Know where I must put this small sponge again at this place !
I expect an answer...merci - Anonymous
There is a sponge to the right of the ink cart that gets pushed up to prime each ink cart. The sponge then drops back down when finished. The problem is that the sponge gets stuck up. Just give it a tap and it will fall down, turn off then on and all fixed.

I would be willing to bet that the fake ink clogs it by design. When will these idiots realize that people will find a way around everything. If they dropped the ink price by a half, I would buy it. The money they loose adds up. I have refilled my carts 6 times so far, with one refilling kit. Add it up! - unknown

Yeah! I followed the instructions to reseat the ink holder home pad, and the 6A00 Error problem was resolved! In my case, it was not the actual sponge, but the white plastic sponge holder that needed to be pushed back into position aside the paper feed placket. My issue resulted from a paper jam that apparently dislocated the sponge holder when the crumbled paper was pulled through the paper feed. This is an awesome and invaluable forum for DIY printer repair. I was ready to run out and purchase a new printer, but decided to keep reading through the postings when I found the fix.

I took the advise and checked sponge a tiny rectangular shape area. I found a piece of paper. I removed it and printer still had 6A00. I put my hand in and found that there is spring there that had come loose. Right where the paper was. I was quite careful when i removed the paper and it came out easily. I do think that the paper there got stuck between head and spring. I think it's easy to repair, but this machine is a pain to open. - Anonymous
That worked for me! Thanks for the advice!! - Anonymous

Glad that I knew by "torch" you meant "flashlight" here in the states. Hope one of my fellow Yanks didn't pull out a propane "torch".

THIS really does work! Even though I could barely understand the directions, this fixed my problem with my MP830! Thank you! Here's what I did:
1) Turn off Printer
2) Open the printer
3) Move the ink to the left
4) Look in the space to the right where the cartridges usually stay and there is a little tray/lever that is covered in a small sponge (mine was covered in ink as well)
5) Poke/wiggle the sponge/tray until it pops into place (I barely had to touch mine)
6) Turn the printer back on, and voila!
This really worked for me, good luck! - Anonymous
You are amazing! You were exactly right, that little sponge had popped up. As soon as I pushed it back down, it began to work again! thank you thank you thank you.... sincerely, bev - Anonymous

Anonymous - your fix worked. I wiggled the little rectangular sponge (it's not soft like a sponge, but looks like one) around a little bit with a pen and got it back sitting flat in it's compartment. There's a small piece of plastic with a little black squeegee-looking flap that I clicked back in place. The error message is now gone and the printer is working.

Thanks. - vegas
This worked! Thank you!! - Anonymous
That's thrue.I could push the sponge back on his place and after restarting the error 6A00 was disappeared.

For those of you in the USA, I believe the kind British person who write this post means to use a 'flashlight', not a torch, as to those of us in the US, a 'torch' will certainly melt your printer. - Anonymous
your right i tried this and it worked - Anonymous
This seems to be the problem area. I did as you suggested and depressed the foam pads a number of times (they didnt seem to be out of place)

I came out looking like a coal miner but it did cure the error message.

The only trouble now is that it seems to have put the printing out of whack so I will try and recalibrate.

Thanks for the tip - unknown
Your instruction was spot on, i did just what you instructed and its like magic, the printer starts working again after i switch it on.

However, i could not find the sponge, what i did was push the ink cartridge all the way to the left manually as instructed. I could not find the sponge you mention, but on the right end, I just put in my fingers to clean all the moving parts that could look like a sponge and its magic.

This is a good website to get error code A600 fixed. - kim chew
Thanks! IT WORKED! Well worth having ink all over my fingers!!!! I was about to go buy a new printer until I saw your post. I APPRECIATE YOUR TIP!!! - unknown
I had the same problem on a brand new MP830. I brought it home, tried to do the easy setup steps, and after I installed the ink cartridges, the print head moved to the right (home) and then I received an error saying that I needed to install the ink tanks (which I just did!). After a restart, I was stuck in the 6A00 wilderness. After reading this thread, I realized that the issue had to be the purge unit. On my MP830, the purge unit is a white plastic assembly (on the right side of the printer where the print head homes) that is spring loaded on rides on a rail. I moved it back and forth (actually forward and back) about 5 times, closed everything up, and after a restart, all is well. Note the the purge unit is NOT the print head!

A HUGE thank you to BAB.

I had this same errror code (Error 6A00) for my MP830. I shut off the printer, rocked the white plastic purge unit (per your advice). I turned the printer back on and it works great!!
BTW, Cannon did want me to send it for sevice too!!! There not getting my $$ this time!!

Easy fix! Thank you so much!!

Thank you so much to briceg for the very accurate description of the white plastic thingy ... I found a leaf from a plant which had dropped into the machine, and moving the white plastic thingy released it, I pulled it out, and brilliant - all is working again, with the ##357 code gone and the 6A00 gone! and only a little ink on my fingers!
I am very grateful! (To BAB too!) - unknown
Like to say thank you very much for your help Bab and briceg. I wiggled the white assembly a couple of times and it (Error 6400) completely fixed itself.

Same problem with the infamous error 6A00. I have a Canon MP830 and did the same as "briceg", except only onces. Move the white plastic assembly forward and then all the way back. Move the print head back to the right, closed lid and turned it on. It work like a charm...up and running. "A HUGE thank you to BAB!" - Anonymous

After reading several postings. I came across this one.

MP830, the purge unit is a white plastic assembly (on the right side of the printer where the print head homes) that is spring loaded on rides on a rail. I moved it back and forth (actually forward and back) about 5 times, closed everything up, and after a restart, all is well.

These directions were great and worked perfectly...I was almost ready to junk this Pixma MP830 because I was convinced it would cost more to repair than it was worth (2.5 years old). Thank you SO MUCH!!!! - RAYBABE
My 2 year old MP830 giving me 6A00 on the display.

I followed BAB and briceg's advice after trying a lot on my own. The purge unit is a low profile white plastic slider that you'll have to reach on the right. It slides perpendicular to the printer cartidge assembly. I slide the purge unit around and depressed the flap on it a few times. Got ink on my fingers but after a restart, the printer now works! - wgu
How do you get at the purge unit? With the printhead stuck, I can't get to the purge unit? - unknown
Your explanation of where the purge unit resided on the 830 did the trick for me. Thank you so very much! Yahoo - working again. - unknown
You have the most detailed and helpful steps on what a purge unit is and what to do with it to get rid of the error. I followed the steps you described and after 2 tries, my printer was up & working again. By the way this was my first error on this printer after having it for almost 4 yrs. now.

Big thanks to you briceg and to BAB! - mdlc
I don't get a numeric code, just "paper jammed -- clear paper jam and press OK"

I have pressed OK. and Reset. and turned it off and on, with and without unplugging. and removed and replaced ink carts (which normally light up but now don't). and turned it on while holding down reset (that's old-school). and moved the ink carriage back and forth several times before turning off. and depressed the purge thing before turning off. no change.

I'm told there was a piece of paper stuck but that it came out whole, but I can't confirm that.

I'm having the exact same problem - can't find any foreign object anywhere. At first, removing the one peice of paper that WAS jamming and hitting okay would give you another try prior to getting the jam message again - now though, that error won't clear at all.

Have you got anywhere. I am also having the same problem - Anonymous
I have a Canon MP830 with an error that says "Paper output slot, the paper is jammed, clear the paper and press OK".

The jammed paper came out in one piece, and I can find no trace of paper anywhere. I have turned the machine on and off, but always the same error. I have even tried vacuuming out around the output slot roller and inside but still no luck. I can't use the clean rollers option because I can't get around this error.

I would really rather not drive 1 1/2 hours to nearest service center. Any suggestions would be greatly appreciated.

After days of fussing about ERROR MESSAGE 6AOO the fix was easy

With the printer lid open as if to change a cartridge. Locate the small screw on the then exposed top right front -- loosen it about one turn and everything was back in working order. Tighten it again and no more problem.

hooray -- good luck

I have a Pixma MP760 and it doesn't print. It starts up with an error message "Error. Turn the machine off and on". Nothing I do has fixed it. It worked OK and the next time I got that message. The door opens automatically at the start if that matters. I've tried unplugging the power and the USB cords to no avail. Any ideas.

unfortunately I don't think my problem will fix with the 6A00 repair routine. The printer gives me a 5100 error message which says that the "type of printhead is incorrect. Install the correct printhead". This is very strange since the printhead is exactly that supplied with the mp800 when it was purchased new. Either my (authorised) supplier is exchanging the authentic printhead for a dodgy copy or the printer analysis of the problem is faulty.
There are no paper jams. I've tried most of the moves suggested here...cleaning the printhead, depressing the purge sponges etc. I will keep trying to find the problem, but any help will be really welcome.

JphnLSD,.... Well John, you need to read some of these posts much closer. Turn your printer on and open the total cover as if you are going to change the ink carts. The printhead and ink carts should come to the center of your Multifunction Unit. When it is parked there, pull the power cord out of the printer. Don't turn the power off as this will return the printhead to the far right and LOCK IT IN PLACE. Now that the power is off, you can move the printhead asm to the far left and this will give you a little more room to access the purge unit. Do what the other suggestions have mentioned. Use a paper towel and press the suction pads down. Try and move the white wiper blade and see if it is stuck. Use an eye dropper and put some windex on each pad. The large pad is for the black ink and the small one is for colored ink. Cycle the power on/off a couple of time to suck the windex through the purge unit.

If none of that works, spray some windex in the area of the purge unit and turn the power on/off a couple of times.

I have had my MP800 for a couple years and it has worked flawlessly. This morning I got the 6A00 error message. I googled the message number and got this page. Bravo. The advice is priceless, as after a minute or so I was able to push down that white thingy in the sponge thing on the right and the printer came back to life. Many, many thanks. I have had such great success with this printer that I would look for a newer model of this printer whenever I need to replace this one.

John,... The bad news is NO. Whatever has jammed the purge unit into the the carriage asm can't be fixed without taking the printer apart. Even then it is going to be difficult.

Here are a couple of things to try. You mentioned the white rocker are moves up and down, but this is very hard to see with the covers closed so you must have seen then when it was open. Try this again and when you see the rocker arm go down, pull the power cord immediatley. This is supposed to free the carriage to be moved by hand,... that is if it is not locked in position by some other jam condition. When the power is off try and move the carriage by hand, but never force it. You will break something if is is jammed and you need a much closer inspection to try and remove the jam. If you are able to move the carriage away from the purge unit, look and see what could have cause the jam. There are all kinds of things that could be wrong. The Spring that retracts the wiper blades may have come off and jammed the carriage asm, or the purge gears broke and the purge unit is jammed. Send me an email by clicking on my name and I will send you more information on how you can fix this.

6A00 is a problem with the sheet feed unit.
Follow Canon's suggestion, take it or send the unit UPS to the Authorized Repair Facility.
You will NOT be able to resolve the problem yourself.

I have a Canon PIXMA ip5200 that was less than 6 months old and used very little.

Canon service said to either take to service center or have a refurbished unit sent. I opted for the refurb. While waiting for the refurb unit, I tried the suggestioin of simply moving the cartridge back and forth a few times. Fixed it! Why couldn't the service tech tell me this???????

I've recently purchased a MP800. It was printing a word document, double-sided (duplex print) and suddenly on the 3rd page, a big "crunch" sound. Paper was jammed - error 5100 or smthg, and managed to remove the paper... but then error 6A00 came up. I found this post and was saved. Manually moved the print head left and right, turned the printer on/off. Still the same error. Then I noticed a piece of torn paper lodged inside. Removed that, got inky fingers, and vwallah, printer is working.

P.S. Called Australia tech support and managed to fix it myself before I even got past the 'hold' music.

Had the printer a week and a half. Printed three pieces of paper and now I have an error code. The service center wants me to drive the thing 85 miles one way for somebody to look at it. Then he offers to send me a refurbished model. Mine is not even 2 weeks old and I could get a old model that someone has used for 12 months. That is not right. Who is to say that I get the refurbished model and it won't do the same thing. That's what I get for being cost effect and ordering cheaper on the internet. I can't return it to store in California from Alabama. Thanks for the hints but they did not work on my printer.

My MP830 was 6 weeks old when I heard a loud crunching while duplex (double-sided) printing. Error Code 5100 was on display. I eventually found paper jammed in the machine and removed it. I turned the machine on and off, and the loud crunching sound was still there. I realized something was wrong with the print head. It wasn't moving; so, I moved it myself. I turned the machine on and of again--same crunching sound. Called Canon and opted for a refurbished unit--even though, like poster wrote, mine was only a few weeks old, and I could have a refurb that is much older than mine. What if there is a problem with the refurb? I think there is something wrong with these Canon Pixma printers. I had a MP780 that was about 2 years old when it stopped powering on. Now, it powers on only sporadically. Never know when it is going to work or not. Canon's service centers--I only know of two--are not conveniently located. I won't be buying another Pixma ever again. - Anonymous
I followed what everyone else suggested. Took out all the ink cartridge, pushed the cartridge holder back and forth and cleaned the inside without taking it apart. The printer works great - unknown
I have had my MP830 over a year with no problems. I ran out of ink and when I replaced the ink I now get a Error 6A00 code. I read all of the write-ins but to no avail. There is no paper-jams, but I do see that the printhead does not move when I turn it on. Any ideas???? - unknown

I had similar problems with the Pixma MP780. After 8 mos at first they sent me 2 different printheads. When that didn't solve the problem, they sent me a refurbished unit. Now the refurbished unit is making a loud crunching noise with error A600. These machines produce great work; the only trouble is in my experience they hardly work.

i have an ip4200 with error 6A00. both my lights flash and the print head does not slide (except manually). This is what happens - (the orange light flashes 11 times).

does my problem sound non-home-fixable?

Your A600 is a paper path error, usually related to the purge unit. Try checking the purge unit for paper stuck in it. Don't even think of trying to replace it, very hard to do on an iP-MP800 series unit. Contact a Canon authorized center for that. You could still be under warranty and that would be covered. Contact http://www.beckscrs.com - BAB
that is a lift cam timing problem. its not somthing you want to try yourself but its simply to re time if your comfortable and confident - rrrohan

I've got the 6A00 error message as well on my MP830, and it looks like the print head is stuck. Is there a way of manually moving it? I don't want to force it too much if it isn't supposed to be moved manually! Thanks!
by unknown on Mar 22, 2007 at 3:46am Add comment
Ok Well again I will repeat this answer with a titch more detail.
The 6A00 is a Canon generic code for paper path jam. Some where in the paper path a sensor is activated indicating paper jam so the printer will give off a 6A00 code. As a Canon tech, I usually find the code, almost 90\% of the time, is related to the purge unit being jammed with something and not being able to move. Moving the print head assembly will not clear a purge unit if its jammed with paper, paper clips, push pins, screws, cookie crisp, flower bud pods or the like. And yes I have found all those things in a purge unit. The offending item needs to be removed or the purge unit needs replacement. A Pixma MP830 would still be under Canon warranty, get it into a shop and save yourself the hassel.
Incidently, the 6A00 error pertains to all Canon printers made in the last several years, its not just used in one model. And its always a paper path error or purge unit.
I forget myself so here goes, the purge unit, called a spittoon assembly in an HP, lexmark, and other inkjet printers, is where the print head assembly parks when not in use, also its other job is to clean and make sure the print head is clean and open for printing. That is why you'll find the print head assembly parked on top of it. It also has a an electrical pump to milk the print heads and test for ink flow.

Where is the purge unit.

The saga continues. Exact same story for me with a new MP970. Having read your words of wisdom, I slid the cartridge holder out of the way and reached into the right hand side where the cartridge holder had been parked. Got lots of black ink. Cleaned this up and the problem has gone. I think I've been a bit lucky but your advice gave me a flying start. Many thanks. - Anonymous
I am a real estate agent desperate to print a contract and I'm getting the 6A00 error... following having gotten the 5100 error which has now disappeared. I have rebooted several times. I have unplugged and shaken the thing upside down. I have looked everywhere for a paper jam and can't find one. I have removed and reinstalled all the ink cartridges. I have manually slid the ink cartridges back and forth. I have looked for the white purge unit to jiggle it but am unsure of where it is (to the right?). I am now covered with ink and have a one month old o contend with.

Anything I can try before my head pops off or I have to go buy a new printer? - Anonymous
Thanks for your message...It was of great assistance. I've been a loyal HP user and decided to change brands and purchased the mp970. I've owned it for 1 yr 3mnts and is for home use only;NO heavy use.
I searched hours for this 6A00 error as it was quiet unexpected and no info. was published in the manual or on their website. More suprising was the response I received from Canon tech. They wanted me to send it for repair 2 hours away!!

I've had better luck with HP printers malfunctioning after4-6 years of use!!! I'm serioulsy questioning my switch to canon printers!!

My question to you as a canon tech is what canon printer should consumers consider that gets the fewest repair calls.

You are a genius BAB, thank you for the tips.

I got the problem "Check Printer OK" on the LCD and the Alarm was flashing (orange). I didnt know what to do but thanks to all your advice to move the ink compartment back and forth and turned off and on the unit. It worked! and now my printer is printer again although got some inks on my fingers which is better than going to a service center!

Thanks so much for sharing!

I need a complete carriage assembly for my canon pixma mp780 - Anonymous
I've never had any trouble with this machine till today. I tried for the 1st time to print a photo on 4x6 glossy photo paper from the cassette tray. It sounded like it was printing, then fininshed, but nothing came out. I've opened the unit and can't find the paper anywhere. The error message says paper is jamed in exit slot. The print heads do not move to the center when I open the unit as it used to. I can't even turn the machine off since it says it is still in use. Can you help? - Anonymous
Thinks for your inputs.
Where can I buy a new printing head for a Canon MP800, and how much does it cost?
Yellow does not print anymore.
My MP800 is for familiy use, and only 6 month old. It hasn't been used very much.
Should I buy a new printing head or do you have a better idea?

Hi - I have had my printer for just over a year (yes now out of warrantee.) We have had some power outages in the last few days, but that has not caused problems in the past. Ironically, my PC's fan went in the last few days as well - not doing well here :-(!

I am now getting the famous 6A00 code. I have tried all the things with the print purge area etc. with no luck. There is no service center near where I live, so I am really out of luck. It would not pay me to ship it anywhere, so I am open to try anything at this point.

When I turn it on, it sounds like it is trying to move the print cartridge unit but then I get the error and nothing from there!

Any suggestions would be appreciated.

Thanks. - Anonymous
How does a layman deal with a full waste-ink-absorber in a PIXMA 830? Any clues? Canon is mum about it and want us to 1) bring or ship it to a service center or purchase a new machine. Quite a racket. - Anonymous
Hi Wonder if you can help.
Have inherited MP780 from brother in law who sadly passed away.
Doesnt work at all.
Has WRONG CARTRIDGE error, and carriage does not move across to centre so cant access it.

Called Canon and their agents who say cant do anything other than send out engineer at $120 or so (plus parts of course) which isnt affordable/justified.

Have you any ideas please on how I go about stripping it down to see if I can identify the problem myself; might then be able to afford part or parts.
I'm reasonably technical but not especially so. WOuldnt want to spend hours and hours on it.
thanks for any feedback of any kind

This did the trick for me too. On the right hand side, on the bottom, there is this white assembly with kind of a fim on top. It looks a little like the film on the bottom of the print head. You need to move it a couple of time back and forth. I can't believe it.. it work !! :) - Anonymous

Hi! I have a Canon MP600 and got the error code 6A00. I have tried manually moving the cartridge, as suggested, nothing works to get rid of the error. I did notice a paper jam before this happened. I am so upset. I got laid off and have only had this printer for 7 months. Just to come to my house or even bring it to a Canon repair facility, it will cost $150 for the first hour. Do you have any recommendations? THANK YOU VERY MUCH. Pat - Anonymous

I read your response from several years ago and am hoping you are still on line and able to help. I am confused about what exactly is a purge unit (does mine have one, and how do I identify it, access it, clean and/or move it?).

The print head holder on my new mp620 is stuck on the right hand side and when I turn the power on it does not budge. Did you ever figure out how to get yours to move to the center? Mine just gives me the error code C000 "Printer Error has occurred. Turn off power and then back on again. If problem persists see the manual." The problem persists and the manual is of no use whatsoever. When I turn it on it makes a whirring noise, but there is no movement. It was working fine last week when I bought it in the USA. I packed it in padding and placed it in a hardside suitcase and brought it with me to Uruguay whereupon turning it on I am now at the point described above. Any helpful suggestions? - Anonymous
I have a Canon mp830 showing error code 6A00. The service agents tell me that I should throw the machine away. It is not worth fixing. Can you help? I have good technical skills and with the right parts & info I am sure I can get it working again. It is such a waste to throw away a good machine that I paid good money for.

Please explain in more detail what and where the purge unit is. I moved the print head but that did nothing and the opening to the printer where the ink is , is not very large.

I have an MP760 that has worked flawlessly for 18 months, I've always used genuine cartridges, Canon photo paper, standard 80gsm plain paper, and a fair few cd/dvd's all without a hitch.

Recently something fell into the rear paper feed, while priming there was an ungodly crunch and the belt for print carriage was shredded and snapped, I sourced and fitted a new belt and now I'm getting a 6A00 error.

While replacing the belt I found a broken piece of white plastic in the left hand purge area, not sure what or where it's from or what damage it may have done.

But now it doesn't attempt to move the print carriage or paper feed at all on power up, just spits out an error, and says turn the machine off an on, even if I remove the ink tanks and/or print head theres no change.

After about 3 minutes the scanner moves back and forward a little but everything else is completely unresponsive.

Is there a timing mark or something I may have messed up during re-assembly?

Any help would be greatly appreciated, I'm getting desperate.

Not a problem with the carriage assembly. Go to www.beckscrs.com. and see in parts if they list it, if not do an inquirey and I'm sure they'll get one for you!

In the rear of the printer there is a removable panel that gives you access to the paper feed rollers, you should find your photo paper there.

For future reference use photo paper from the rear auto sheet feeder.

I have the 3 orange-blink error, and it claims there is a jam in the exit tray. I can find nothing. I have jiggled the purge unit (moves, but not much... 1/4 inch or so), and slid the ink-tank housing back and forth. All the gray sponges seem to be in place, but it (MP800) wont feed paper from the top tray. It acts like it is going to pull the paper as per usual, then pops it up a 1/2 inch or so, and doesn't catch it again. Earlier, we had problems with a few pages getting caught and bent on the way in (bottom right side), but no crunching or tearing or anything horrible.

I can't get the thing to take my paper.

Any ideas?

Have had a MP780 since first available, so one of very early production models. Occasionally it has made a load (!) mechanical ratcheting like noise (7 - 10 quick clicks) and then goes into "Check printer, press ok". I can't find anything stuck or other problems but press OK and it does same thing. In the past I would turn it off for a while and when turned back on, it would work, but is a solid failure now. Since it's out of warranty, I figure any significant repair would cost more than printer is worth. Any suggestions for a 'self-fix'.

My home recent took a lightning strike and I lost several electronic items but have been able to bring some back to life with reset buttons, power disconnects/reconnects, etc. I got my computer to live once again, but the Canon MP780 shows not sign of life. I disconnected AC cord and reconnected, nothing. I don't see any accessible reset button and am ready to open it up. Has anyone had a similar power surge issue that you were able to recover from? (btw, everything was on surge suppressors. they work OK for electrical spikes, but they don't slow down 300 million volts from lightning.)

I have had my MP800 for nearly 2 years I think. Never had any problem with it. Recently have been printing 4x6 color photos, probably around 60-70 the past couple of months, using the cassette. Never had any problem with that either (except for a tiny bit of ink sometimes tipping one corner of the photo). However, last night suddenly the printer started to malfunction. It loaded and began printing the photo (borderless 4x6 landscape) and completed about 2/3 of the print just fine when it made a brief, odd little noise, followed by a slight clicking noise, the latter which continued as it completed the print. I printed another photo and noticed that simultaneous with the odd noise, I could see the photo change path, sliding to the right, as it was passing forward through the rollers. The output shows the last 1/3 of the print about 1/8 inch out of line with the first 2/3. So it looks like a distorted smear at that point on the photo, about 1/8 inch wide, which occurred when it slid right while still printing. I cleaned the jets and the rollers and also tried using the auto sheet feeded instead of the cassette. The problematic behavior remains the same. I tried a test with 8 1/2 x11 paper and it appeared to feed just fine.
This problem simply started out of the blue, with no apparent cause. Is it likely to be some problem with the rollers or some foreign object that somehow got into the way? I'm going to examine the printer more closely tonight with a flashlight, but I'm mystified what might have happened to cause this and how I can fix it. Any suggestions?

I have a canon MP500 and I've been getting the 6A00 code. I looked everywhere inside and could not see any paper or anything else causing a jam. I moved the print head back and forth, removed all ink tanks and put them back in, moved the white thing back and forth a number of times, and pressed on the sponge under the white thing and nothing has worked. When I turn the printer on it makes noise, but the print head does not move at all on its own. Also, when I open the printer the white thing on the far right side is always towards the front side of the printer. I can move it back and forth and it's springy to a certain point. Then I can push it further and it stays towards the back unless I pull it forward. Could the problem be something to do with this?

Thanks in advance for any help you can give!

I had to move the print heads back and forth about 50 times and turned it on and off before I got it to work. I still can't print from the top feeder, only from the bottom feeder. I figure the problem is somewhere between where the top feeder starts up to the place where it meets up with the bottom feeder assembly.

I am just going to stick with the bottom feeder. - unknown
Would just like to say thank you for this troubleshooting, I have an IP4000 which had the 6A00 error... After pushing the white thing (purge unit or whatever it was), so hard it sounded like something broke, everything works perfectly again :D

Mine (MP830) was the white plastic thingy with the rubber wiper. It was gummed up with old ink residue and wouldn't slide back to where it belonged. I took it all apart and cleaned off the residue with plain water and paper towels. Lots and lots of paper towels!!!

I have the code error 6A00 - managed to retrieve a bit of paper from the right hand side but I cantt actually move the print carriage from the right to the left. It physically wont move. Have tried turning machine on and off and it gets to the point whre the cartridge carriage usually moves across to the middle but then it doesnt it just stops and says code error 6A00.

Is there anyway I can unscre an area to manually move the cartridges out the way.

just like to ask if someone has a service manual for Canon Pixma MP530. i need to get a tack that was lodged in the middle of the printer.


by nolany on Nov 9, 2007 at 2:56pm Add comment
Just an added bit of information to others that may want to use the fixes posted on this thread. May people imply that you can just open the cover and physically move the printhead carriage. Once you open the cover, the printer should move the carriage to the center to allow you to remove/replace ink carts. You should remove the power plug before you try and move the carriage anyplace. If you try and move it will the power on, you may damage the drive belt or drive motor. When the power is off, the carriage can be moved easily. Move it to the far left so you can get at the purge area better.

As other have indicated, there are many things that can cause the purge cleaning station to lock up. Most of them have to do with too much dried up ink. Many people just press the ink pads down, since they are spring loaded, and if they had been stuck this will temporaryly free them. The same goes with the white nylon wiper. It can get stuck over at the station that cleans the wiper. Again, it is almost always lots of sticky ink. Sliding in back and forth is another temporary fix.

My suggestion is to wet a paper towel with windex and wipe as much of the ink off as you can. Clean the pads, the while nylon arm, and the soft wiper as good as you can. I would also suggest that you use a syringe or an eye dropper and put several drops of Windex(or water) on each pad and let it soak down through the Purge unit. Put enough windex on each pad so they are flooded. It isn't going to hurt anything if it overflows a little. After all, this is a cleaning station and it spits out ink just about everytime you turn the power on. Fill the pads and cycle the power on and off. The purge unit will suck up the windex and flush it's tubes out. I would suggest doing this at least every six months.

While your at it, and you have the carriage in the center and the power off, do a minimal cleaning of the printhead. Take the ink carts out and cap them so they don't leak. Remove the printhead and use a paper towel wet with windex to very gently wipe all the ink of the bottom of the printhead. Check that their are no LARGE puddles of ink inside the printhead where the ink carts set. Put it all back together and you are good to go.

Some people have a difficult time getting the printhead out. First you have to unlock the printhead by raising the gray lever on the right side of the carriage. To remove the printhead, you need to use a small downward and forward pressure and then it will pull up and out. The only place to get a hold of it is inside at the very top, left and right side.

Hope this help others.

First of all, I would like to thank everyone who posted possible solutions to this 6A00 error code! My warranty expired a month ago and I'm not too thrilled about paying to have the thing fixed. The Canon website was not helpful at all. I was ready to give up, go out and buy an HP before I stumbled on this site.

I moved the sliding piece with the wipers back and forth several times. I also pushed down on the pads. This fixed the problem -- at least for now. Considering the amount of sticky ink on my fingers, I will defintely follow the instructions on cleaning the purge station.

Again, thank you everyone! - Anonymous
Hope you can help.
My MP830 screen does not light up.
The alarm light is on?
The printer power comes on and when I open the cover the printhead moves to the centre.
Would you know why do the screen not working???And why are the alarm light on?
Please advise. - Anonymous
I noticed that this was the problem when:
1. The print head cartridge keeps locking itself up on the right hand side.
2. Frequent 5100 errors even when the printer is on standby
3. Even when I wipe up the print cartridge, the next print will mess up the bottom of the print cartridge with ink again.

Solved the problem by following trigger1937's outlined steps:

1. Opening the cover and wait for ink carriage to center
2. Pull out power cord
3. Pushed carriage to far left (should slide easily)
4. Used paper towel and wiped purge unit a lot of times (press down to soak paper towel with ink). Repeat until the paper towel is relatively clear.
5. Used diluted napisan (oxygen-based cleaning agent in the ratio of 1:3 with powder:water) and soaked paper towel
6. Repeat step 4 with wet paper towel. Repeat until purge unit is near-white.
7. Pulled and pushed clear plastic wiper (north of purge unit) and wiped it down
8. Slided carriage back to original position
9. Removed Print head cartridge and wiped out excess ink stuck on bottom.
10. Plugged power back on.

This worked for me. - unknown
Amusing that your post of almost a year ago was the right 'fix' for this vexing little problem with "Error 6A00" that just appeared on my 1 year old 830.

I produce volumes of double-sided copy, and was just about to throw the little Pixie PIXMA over the side of the ledge which is memorialized in my screen name, when I found your solution.
This approach makes abundant sense, as ink build-up is the number one cause of lost production in my other printers (all others HP).

Thank you so much for providing fairly easy (and hopefully repeatable) solution to this issue for which Canon (as other writers attest)has none. - Anonymous
My Pixma MP530 was working great until I started receiving "Check printer", "6A00" and sometimes "5C10" error messages, and everything seems to have shut down. I can't even run nozzle checks or any other maintenance procedures. I've tried many of the suggestions recommended on this forum, including cleaning the print head and other areas that I can reach and/or remove, and making sure the purge cleaning station isn't locked up. I haven't been able to find any paper jams or foreign objects and the print head seems to move freely when I manually move it. When I was working in the area of the purge cleaning station, I seem to have dislodged a clear (in color), flexible, rubber (or plastic) part that is approximately an inch long and has 3 small holes in it. Was this perhaps the wiper mechanism, or at least part of it? There seems to be another similar part still in place. Have I done irreparable damage to the purge cleaning station by somehow dislodging this part? I've tried, but can't seem to figure out how to place it back where it might have come from. Any suggestions on what else I might do? Thank you. - boydkelley
@trigger1937, thank you for the info!
Mine was a work printer, and occassionally got the 6A00 error but usually seemed to fix itself temporarily or someone else moved things around enough to make it work, but this time it seemed to be permanent. I tried everything else mentioned here, including moving the purge station and pressing on the little ink pad, but nothing worked.
I noticed that the white piece was stuck at the front all time time, so I cleaned it all out as best as I could and even cleaned out the printhead for good measure, and now it works great!
I'm sure my bosses will appreciate not needing to buy a new printer now for at least awhile, thanks again :) - Kazamaraz
On someone else's tip, I fixed my problem. Turn the power off (unplug it)and open up the unit to expose the printer ink cartridge holders. They are not in sight but are homed in at the far right. You can manually slide the entire ink holder mechanism to the far left. Use a flashlight to view the right hand section and you should see two black sponges sitting in a plastic shell. Stick you hand in and press the sponges downward. They should move downward and if they don't, then this may not fix your printer as it did mine. Once you've done this, move the printer mechanism back to the far right, drop the lid in place and the flap in front of the inks (see instructions for replacing cartridges if unsure here). Plug it up and power on. It will take a few minutes for the unit to boot up properly. Next print a simple message from email, etc. Again, it may take a few minutes for the printer to get itself realigned but should now work

Hello, I seem to be having the same problem as everybody else with the 6a00 error. I have moved the purge unit up and down, moved the ink holder mechanism back and forth, cleaned the general area, and turned the printer on and off. Now, the ink holder mechanism is completely stuck to the far right and I can't move it manually. Is there any advice for this problem and if not does anyone have any links or resources for disassembling the unit.

I was cleaning the print heads when the ink holder mechanism stuck on the right side. I can not move it manually. I have blown air in and used isoprpyl alcohol to clean what I can, but can't get anywhere near the purge unit.

I even purchased the service manual and started taking the printer apart, but stopped when I had to start taking things off the motherboard.

Any help is greatly appreciated. Thanks.

I encountered the same problem in a 6-month old machine and have been unable to fix, despite great advice in this forum. The spring finally popped off the purge unit and I'm calling it quits. It puzzles me that a machine of such obvious poor quality, which consumes ink by the gallon could get such high reviews. Oh, well, back to HP.

Model MP830

I was getting Error 6A00 and it turned out to be that the black cartridge felt cleaning sponge had been lifted out of it's well by a sticky print head and it was lodged in the front of the well. So the wiper could not seat all of the way. I reached in and around where I couldn't see with my index finger and felt the pad. I was able to pull it out and the error code went away. Moral is make sure that white plastic wiper can seat all of the way. Follow it's path with a finger and make sure your pad isn't lodged in there too.

Thanks to all in this group for some very useful pointers. I have just posted my experience on another thread, but I thought it was worth copying here ...

I had the dreaded ambiguous 6A00 on my 2 year old MP800R.

Having Googled around, I noticed that the left most pad in the cleaning assembly had popped out. This pad is about 25mm x 8mm x 2mm and made of a stiff porous dark grey material.

I tried to pop the pad back into its housing without disassembling the printer. This was a mistake because I didn't quite get it seated correctly. The pad then went missing, and I still had the error. I then reckoned that I had nothing to lose ...

So I stripped the printer/scanner down. It's amazing how much technology is packed in such a small space. The strip down, repair and reassembly took me about two hours.

A lot of this time was spent wondering how to get the shell apart, and dithering over whether to continue. You also have to remove the whole scanner assembly before you can get to the printer.

Using a dentist-style mirror I found that the pad had got lodged in the black pump (?) unit right at the front of the cleaning assembly. But I managed to remove it and clip it firmly back in place.

I tested it before putting the case back on ... and bingo ... it worked!

Snapping the case together is a lot easier with the thin black shiny plastic bits at the front removed (they snap in easily last of all). I suspect taking the case apart would be a lot easier with these pieces removed first (at least I'll know about that next time around)!

I have an iP6600D. Same error code [6A00] came after some paper crunched through due to misalignment in the feed. The challenge was getting the printer open. Once I was able to remove the top cover, I too found a piece of paper jammed in the print head. Once removed it worked fine again.

I am getting the dreaded MP830 6A00 error. I presume it is a stuck print head as it occurred shortly after replacing an ink cartridge (I also have checked for paper clips, bits of paper, etc. just in case).

I cannot move the print head manually. It is stuck over at the far right ... only a fraction of an inch is visible. With power off, I have tried wiggling it left/right and back-and-forth, then restarting the printer. No luck.

Several people have mentioned doing things with the white purge unit. I cannot find the purge unit. I gather that the print heads rest on it but I can't see it (unless maybe I am looking at it and not recognizing it). Is there a way to see it (or at least move it) without disassembling the printer?
by JohnLSD on Jan 18, 2008 at 5:47pm Add comment
JohnLSD & Trigger,
I have the same problem. For my problem, there seems to be a latch or something that comes up and holds the print head in place, so it won't move either. I think what we need is some schematic or simple instruction about how to open the printer up so we can clearly see the 'garage,' and purge unit. From the look of the discussion board some people have done this, so if anyone has any ideas that would be great. I have already purchased another printer, but getting the Canon to work again would be great.

I solve these problems by purchasing a competitor brand of printer. Don't think for one minute that the problems mentioned are from a designers oversight. Desk top printers and copiers in the past have had accessible waste ink reservoirs that the user could service. The manufacturer can insult the consumer all he wants but boycotts effect the bottom line.

I have a Cannon PIXMA MP830. Got the same 6A00 Error code when trying to print. No prior problem with a paper jam, the code just popped up. Followed the advice from the posts above but couldn't find any obstructions (paper, plastic, sponge, etc). Finally just moved the white piece on the right side forward and backward with an inkpen. Turned off the unit and turned back on.... WORKS GREAT!!

if it is jammed on purge unit you need to manual turn the gear that feeds paper through auto sheet feeder. you can either turn the gear on left with the encoder disk or near the purge unit itself. both will involve taking covers off

Just wanted to post what I did for those that are still having problems with their PIXMA MP830 (error 6A00).

1) I locked the scanner & turned the printer off
2) I lifted the top to expose the printer head
3) I moved the printer head all the way to the left
4) in the extreme far right along the bottom of the path where the printer head rides, there is a white plastic piece that moves front to back (instead of left to right). It is a little larger than a stamp. I moved it front to back a few times.
5) I turned the printer back on and voila! no error!

After this I had to deep clean the inkjets b/c I haven't been able to use it in quite a while. However, the main point is that there is now no error and it prints.

Good luck and thanks for this board - it truly helped me.

My MP600 is just out of warranty and has the 6A00 error. I've tried all of the advice from the above MP800 thread and there doesn't seem to be anything stuck in/around the purge unit. I've also cleaned away all dried/sticky ink.

However, when I watch the printer start up (with the print head pushed over to the left) it all goes fine until the purge unit first gets pushed forward. It immediately gets stuck under the black plastic module (with a sort of white cylindrical hinge) opposite it on the front side, at which point 6A00 is reported and everything stops. My finger can free the purge unit up, but cannot make it get stuck again manually. I can't feel anything unusual in the printer and the sponges underneath the purge unit seem to be in place and move up and down just fine. The spring on the purge unit looks alright, although it isn't powerful enough to stop the unit from getting stuck.

I've thought about taking the shell apart to get a better look but am not sure where to start. Can anyone help? Thanks

A 6A00 is a jammed purge unit. Look for paper scraps that may be caught in it! More often then not, thats what we find in the shop.

by BAB on Feb 14, 2008 at 7:48am Add comment
Ok, I did all of the above and it still didn't work so I took the MP600 to a local pc repair shop who did nothing but google the problem, decide they couldn't fix it and charge me £17 for half an hour's labour.

As a last ditch effort before visiting PC World I put a narrow nozzle on the vacuum cleaner and gave it half a minute full blast on and around the purge unit.

This finally did the trick!

There must be a moral in this episode somewhere. Put your answers on a postcard.

I have a canon Multi MP800 the screen is lit up but blank except for streaky but out of focus vertical lines of many colours. Can you help as it may need a part. I am a tech and have almost completely disassembled and reassembled this machine to fix a spring in the lid mechanism so I do not need a service centre to do this type of work on my behalf. Apart from that problem it has been working OK until this week. Also I have a Canon i865 that needs a set of the ink absorbers located in the base. Since that you say you can help by supplying parts perhaps you can help here too.

it not a tank..it is a waste pad, similar to a kotex pad, but different material (or is it?). Its seems like a polyester cotton material that can be washed but be nice, less water is better, since ink is water soluable. I wash it in a laundry tub, and wring it out with kitchen gloves and then a rolling pin.
if you get any on your hands, its a dye...try baking soda/water. or pumice.
your printer counts the number of drop, and registers it in the eeprom of the main board..it has to be reset.

Hi, The same old story of the 6A00 error message.... But my ink tank carriage is stuck to the far right side & cannot be moved (only a little back & forth movement is allowable) I am reasonably tech savy but this problem has me buggered... Most of the remedies here are if the ink tank can be moved but not much on how to get it unstuck if it is stuck !! Just getting the outside covers off seems to be a nightmare so does anyone have any ideas where to start pulling off the covers.. My problem started when the pc was shut down whilst printing or was that a coincidence ??? Can any one please help me with any suggestions... But remember that the ink tank is stuck to the far right (resting position) & cant be moved.
Thank you in advance for any help .... Cheers ...

Hello to all and thank you for your help with this error code of 6A00......it is either a small paper jam or a stuck white plastic piece under the home of the ink tanks to the right of the inside where the ink cart. unit is home based. My mp500 and most all canon all in ones are the same problem.....move the ink tanks to the far right with your hand....printer off of course....then move the white plastic slider with the spring extended to the back of the printer....clean squeegie like cleaner pieces with a damp cloth to remove gummie old ink that made it get stuck....spring will move it back if clean.....again.......the purge unit is a white plastic assembly (on the right side of the printer where the print head homes) that is spring loaded and rides on a rail. I moved it back and forth (actually forward and back) about 5 times, closed everything up, and after a restart, all is well. Note the the purge unit is NOT the print head!

Thx David THE fixer,,, ur advise is good but one thing wrong with what you said is that to get the covers off the outside of the MP800 multi function Printer you need to be nearly a brain surgeon or a rocket scientist or the like to work out how the Japs put it together. so as the get the covers off with out breaking any thing. I am sure that if I can get the covers off this machine i will be able to work out how to free up the print head & clean what needs to be cleaned.... I will keep trying & wont give up..... The Canon service agents all seem to think we are all stupid & cant fix things our selves... Cheers - unknown

Thank heavens for this post! My mother's MP830 showed 6A00 after a paper jam. I was a printer technican a few years ago, and this one had me stumped. Reading this post made me look very carefully (again) at the purge unit, where I found a small piece of the jammed paper blocking the white, spring-loader wiper part of the purge unit towards the front of the machine. Use a mirror if you have one, and a flashlight and look very carefully. I was literally minutes from calling support (and likely getting the "bring it in" diagnosis), when I Google the error code and found this post.

Great suggestions here. Managed to resolve the 6A00 problem. Note that the purge unit on MP800 is located very very far to the right, hidden away where it is hard to see. One of the pads (rectangular, 2.5 cm by 0.5 cm) had come loose and was lying diagonally. Could therefore remove it (with a pair of pointy pliers) and clean it easily with water and window cleaning fluid. Used strong kitchen paper towels (5 successively) soaked in window cleaner to clean the other one (bigger, square, 2.5 cm x 2.5 cm) and the area. Then replaced the one that had come loose. Hope it is properly relocated, since it did not noticeably click into place or something. But all seems to be well.

Hello, I used all of the previous advice to repair my printer twice! However, now I am disassembling the MP830 because the printhead is FIRMLY stuck far right on top of the rectangular shaped 'sponge' that did not stay down this time. I leaned it all up, pushed the sponge back down, printed a few pages and now the printhead won't move at all. I have the sides and front off already. I have unplugged the wires from the motherboard. Unable to figure out how to remove the whole top. Now... how do I get to that printhead?
Thank you EVER so much for your help.

The above notes about the purge unit was spot on for my case. Turned out there was a tiny piece of paper that held the unit back. Solution was to slide the unit forward until the paper came loose and then switch it on again.

Good luck.

RE: Disassembly

I can tell you that you there are plastic tabs on each of the end pieces that must be pushed in with a screwdriver to slip it off after the obvious screws have been removed.

Also... leave the top attached until you get sides and front pieces removed. Also take digital photographs of each removal and of the motherboard when you have it exposed.
Then unplug wires from board which are connected to the main top scanner piece.

That is all I know so far and am stuck right there! Not sure how to get the hinges to disconnect to remove the scanner piece so I can remove top half of main casing. - kreakin
I had the 6A00 like crazy on my MP830.
Fiddled and fiddled with the infamous "white tab" mechanism on the right end... sometimes I would get it freed up for a day or so but it would always get jammed up again.

I was still under warranty and sent it in.
They cross ship you an entirely different unit! This is pretty darn good support in my opinion. My replacement unit appeared to be brand new.

Bottom line, the replacement has been running solid for 7 months now (12/20/2008) without a single issue. I am extremely satisfied with my decision to return to the repair center.

There is a sponge to the right of the ink cart that gets pushed up to prime each ink cart. The sponge then drops back down when finished. The problem is that the sponge gets stuck up. Just give it a tap and it will fall down, turn off then on and all fixed."

With the lid open...turn it off, unplug the power cord, plug the power cord in, turn it on, unplug power cord while still turned on. At some point, the print head may shake loose and you can gently move it to the left out of your way so you can clean the area that it is getting hung up on. (sticky ink) Don't pull on that little arm on the print head too hard. My son pulled too hard and broke mine off.

Try the WD-40 trick mentioned in earlier posting. That works too!

I have read with great interest all the happenings here for the error A600. When we see it in the shop, 9 out of 10 times its a jammed purge unit. We will usually find a scrap of paper or some foreign object lodged in the purge unit preventing the proper movement of the purge unit. Find and clear the problem and your A600 error will go away.
Now if the A600 is there, it will also prevent mechanical movement of the carriage unit, you can move it by hand but it won't move on its own, again look to the purge unit. Again look for some scrap of paper or paper clip, staple or anything that could have made its way into the unit. Children and small objects are also detrimental to printers. Also look for missing or broken encoder strips, another big problem with children around.
No black printing? is it not printing text or graphics? Usually the answer to that one is it won't print text! That already narrows it down to the big PGI-5 ink. Have you let it run empty? If so the print head is probably cooked and needs to be replaced. The big PGI-5 ink is for text printing only, the smaller CLI-8BK is for graphics. If the PGI-5 is allowed to run empty, it will fry the print head and the print head will probably need replacement. If you look on the side of the removable print head you will see the part number ingraved in it, QY6-0061-000. You cannot buy them in a retail store but many Canon authorized places carry them for sale. You can find them online at beckscrs.com. Incidently Canon authorized repair facilities will repair these units for free if under warranty, regardless of how it happened.

I had the 6A00 error on my Cannon MP830 printer. I ended up taking it to the shop. The problem was the pruge unit needed to be replaced. I bought the printer in May of 2007 and put it in the shop on June 11, 2008. They had it for one day and Cannon paid for the repair. Glad I took it in instead of trying to play with it and still wouldn't work.

I had this issue this morning! I moved the printer head and turned off/on several times, removed the feeder and all paper, inspected, turned off/on again....nothing. Then I got serious! I opened the top, moved the printer head all the way to the left, got a flashlight, inspected for paper, dust or any other foreign object. I took a clean white cloth and ran it (gently)over the area that ink flows into. It was sort of sticky as I haven't used it for about a week or so. I got alot of ink on the cloth. Blew it all out with compressed air and then moved the printer head back into position. Turned it off/on....and there ya go. It seems a tech posted something last year above that explained this error is a paper path issue only but also mentioned something about ink flow sensoring. Perhaps the error also pertains to ink globbing up under the printer head. Whatever...it fixed it without hauling the damn thing in and paying a bundle for nothing.

I have a 1 year old MP600, and got the 6A00 code. I turned off the printer, opened it up, slid the ink cartridge thing (I know, so technical) to the left, and checked over to the right w/ a flashlight - found a piece of paper stuck in there. Removed it, everything works fine now.

Just letting people know that sometimes, it can be fixed by something as simple as that.

My job has a 1 yr old MP600 and got the error 6A00. Searching this site gave me the "move forth and back" answere. After trying it a couple of times and searching the printer for paper, dust, cookie crums and the likes I was near giving up. Suddenly the printer seems ok. I had my fingers to the left inside the printer cartridge slide. Maybe I touched the "G-spot" by accident?? Thanks for helping out with this site!

I also got the Error 6A00 message and struggled for a while with my MP760, but after having moved the purge unit on the right side of the printer, and tried restarting a couple of times - voila! It works again - until next time. Thanks for the thread. I came close to ordering a new printer.

I don't have the 6A00 error message, but it says "Paper jam at transport unit - open rear cover and remove." There was no paper jam to be seen anywhere. I turned off and on; out came paper from bottom cassette. I removed it and hit OK, but error message returned. I tried moving cartr to right and dealing with purge unit; even cleaned with windex, but still no change. Of course unit is now 16 months old. Any ideas? thanks

Thanks printerman60. Found a black sensor that was hanging down so I thought I got it back right. Still didn't work (didn't see why it wouldn't), so I prayed about it (I try to do that about everything). Today I turned it on, and the error message (which began 2 weeks ago) was gone!

I'm getting the 6A00 error and have been through all the above external fixes with no success. The white tab on the right side moves freely back and forth. When I hit the on/off I don't see any motion in the tank carrier before the 6A00 error message comes on. I've tried it fully moved to the left and the right. No signs of any debris in the area of the purge unit. Is there anything else I can check? I bought it 11 months ago so presumably it's still under warranty?

Hey printerman60,
I suppose you may be used to attempting answers to stupid questions. Your attitude isn't necessary nor appreciated.
I have determined power is getting as far as the board, so we can assume all the "simple" fixes have been attempted.
Thanks. - harvester3
I also have the 6A00 error on my MP830. It's 1.5 years old, out of warranty. Canon says to have it serviced at my expense, but they'll also give me a 10\% discount on a new printer. I located and bought a service manual for $5 from:
The manual says that error 6A00 means:

An error occurred in the AP motor during purging
operation. Parts which may need replacing are:
- Sheet feed unit
- Logic board
- Purge unit

I've ordered a new purge unit ($35) from another vendor:

The service manual will, hopefully, help me to get the thing apart so that I can install it.

Good luck to all.

Would like more info re grinding noise plus error 5100 in a PIXMA MP800. The shape of letters in some lines is twisted sideways a little. This would seem to me to be a mechanical problem in the gear train. Can loose material in the machine do this? I'm fairly mechanical but don't want to pull much apart, having no background in printers. Thank you for very interesting posts, George

I've had my Pixma 830 for 2 years. It worked fine until today. Tried all suggestions listed. The e-mails from 3/7/07 and briceg were right on the money. I used my fingers to push the plastic piece on the right back and forth a few times, closed everything, and restarted the printer. It awhile to restart, but it's working again! Thanks to everyone for their suggestions.

Dear Real Estate This is the thread that I read "Re: Canon PIXMA MP800 Error 6A00 by Anonymous (3/9/07 11:32 PM) reply + / -
I know this problem- The problem is inside the printer. Turn off the printer and open the replacement ink compartment- move the inks holder far to the left- use a torch (flash light) to check where the inks holder home (all the way right) and you'll see that there is a sponge a tiny rectangular shape come loose -use the twiter(tweezers) and put back in place (holder). Hope this help" This is what I did and reboot the printer and it worked.

Well, code 6A00 represent purge unit is faulty, it is similar with other type.
Based on my experience as Service Engineer,it is not sheet feeder related issue. So, I suggest you contact nearest service center.

Canon Pixma MP760 + 6A00 error code

I also had the 6A00 error code. First there was a standard paper jam at the back assembly. I removed it and a bit tore off and then removed that part. I thought that was it but I still had the error.

After reading your posts above, I tried moving the print head, cleaning the purge parts on the right, etc... with same error code results.

Finally, knowing there was absolutely nothing foreign stuck in there, I reached my fingers in there and I pulled out a 2 inch paper clip. Now everything works just fine..... go figure...

My MP530 had a rubber band stuck in the ink carriage. 6A00 seems to be a "catch all code" meaning it's broke.

It appers that the problem lies between the printer catrage head, the craddle and the ink pool (where the songe is).
What I did: was to move the printer ink to the side opposite it default side, take a spray bottle with quick evaporating alchoal I used Mentholated Spirit but I guess rubbing alchoal can be used also, and Spray that area good.
It worked for me let me know what happen if you try it.

Canon did honor the warranty even though it was about two weeks expired. They sent a new/refurbished unit. I didn't even have to ask, they offered because I had never bothered them before about anything, or something like that.

Generally speaking, this error is related primarily to the purge unit. It either has something stuck in it like a paper scrap or its jammed and needs to be replaced. Not something for the novice to do.

MP830. Got the 6A00 error message. After reading some of the above solutions, I figured out what to do :- To the right of the runner, where the ink cartridges slide on, there is a white plastic piece with a two inch slim spring. I pull the plastic back a little towards me, heard a click. I then turned the machine off and on again - Hey presto!!! Its works again - Yippee!

My MP830 game me error 6A00. I followed intructions above, carefully inspecting for any issues in the purge area or with the white plastic tab. Moved the print head multiple times. I jiggled various structures back and forth. I cleaned the filthy ink from the purge region. I imspected the entire paper path. There was no cure. I became increasingly forceful with trying to move parts until plastic pieces began breaking off. Now the printer is runied. I'm dumping it tomorrow.
This was a useful printer while it lived.

Following some of the advice here, I think I just fixed the Error 6A00 on my Canon MP750.

The alarm light was flashing and the LCD message said to "CHECK PRINTER (PRESS [OK])"

Here's what I did (after doing a hundred other things that didn't work):

1. I opened the printer as if I was changing an ink cartridge.

2. The ink cartridge carriage did not move to the center as it should (one of the symptoms).

3. I moved the ink cartridge by hand to the far left to expose the ink purge area at the far right (under the area where the ink cartridge carriage typically parks itself).

4. I used a small make-up mirror from my wife and a flashlight to look for paper fragments or anything else that might be jammed around in the ink purge area. The mirror was indispensable for viewing areas I couldn't possibly see otherwise.

5. Eureka! I found a some ink-soaked paper fragments crumbled against a roller near the ink purge

6. Now the fun part. While wearing a head flashlight and viewing the small paper jam in the mirror, I used tweezers and needle nose pliers to extract the paper. It was like "Operation," a game I played as a kid, except every movement I made was backwards because of the mirror. It also required some moves that would challenge a circus contortionist.

7. I closed up the printer, hit the okay button, and the printer made some noise like it might work. Unfortunately, the alarm light stayed on. I opened the printer again and noticed that the ink carriage repositioned itself. I took this to be a positive sign as it didn't do this before.

8. I closed up the printer again and hit the okay button again. After several "please wait" messages on the LCD, and positive sounding noises from the printer, the alarm light went out and the printer seemed ready to print.

9. I ran a few test pages through and they printed fine.

Special thanks to BAB, a Canon authorized technician, who's post above edited 3/22/07 5:45 AM, was particularly helpful.

I'm glad the steps worked for you, too.

You are right that it would be wise for Canon to monitor forums like this one, which have postings specifically about problems with their products.

Better yet, Canon should improve its own forums so users like us can find solutions faster!

I found fixyourownprinter.com after exhausting the support available on Canon's website.

>My question to you as a canon tech is what canon printer
>should consumers consider that gets the fewest repair calls.

Sorry, the wording I used in my posting must have given the impression that I'm a Canon technician. I'm not. I was trying to acknowledge a posting that was helpful to me from "BAB," who mentioned that he is a Canon technician. Consequently, I don't know which printers require the fewest repair calls and regret I cannot make any authoritative recommendation, other than to suggest checking the user reviews of printers listed in Amazon. If find these reviews very helpful when making purchase decisions.

FWIW, I've been very happy overall with my Canon MP750 and will consider the current version of this printer when I look for a replacement in the future. The 6A00 error was the first serious problem I've had with this printer in the 3 1/2 years I've owned it.

I am among the growing legions of 6A00 error code victims. I have a Pixma 830 and I am convinced it is NOT a paper jam, but the purge unit problem others have had. However, the printhead is stuck in the right corner in the resting area. I can't get it to move at all. It is under the gray plastic housing inside the case. I read the other notes about moving the head back and forth and cleaning the sponges, but I can't get it to release so I can do the other steps. Can anyone advise me how to free the mechanism? The Canon e-mail support unit advised me to take it to their repair facility an hour away, and the unit is exactly two years old today. Thanks for reading this, and I hope someone can help.

My 1 1/2 year old MP 830 has the same problem. The 6A00 error code appeared today for the first time. I have resd all of the previous posting on this mbut cannot use because my printhead also is stuck in the right position. I can't move it even after turning power on and off including removing the power cord. I, too, am hoping someone can tell me how to move it. Thanks. - puffque
To the last few people that have posted the 6A00 error, It is most likely a jammed Purge unit. Use a flash light with the cover up and with a rubber glove on try and wipe as much of the sticky ink off of the wiper blades. This assumes you can get the printhead to move away from the home position.

The primary problem is that the 1st job of the purge unit is to LOCK the printhead in the parked position. If the purge unit can not do a successful cycle, it will stay in the locked position and you can't get the head away from home. There can be several reasons why the purge unit will not complete the cycle and only one of them is due to being stuck in place by sticky ink pilled up on the wiper blades.

If you can get the head to move to the center, the only way to make it move is to take off the covers. If you want to know how to do that for each specific printer, just click on my USER ID and send me an email and I will respond.

Puffque and Anonymous 1/4/09: My printhead was not locked up like you've described.

In reference to your problem, I tried looking around the service menu (accessed on my MP750 by pressing menu, scan, copy, scan) to see if there is some option there for unlocking the printhead, but I didn't find anything. I also did a google search, but no luck.

trigger1937 is clearly more knowledgeable about these printer problems than I am.

trigger1937: From what you wrote, I gather there is no way of releasing the printhead through the service menu and the only next step would be plastic surgery (removing the covers).

I have an ip3000, and was just freaking out because my class starts in a few hours, and yeah I waited till the last minuet to write and print out my paper. So with flashlight in hand I found a lot of torn paper, and a spring out of sorts. After removing the paper, putting the spring back, getting ink all over my fingers, and gently tapping the printer head, voila! I just finished printing out all 21 pages. You all ROCK!! And if anyone is having trouble with "inky" fingers... an alcohol swab does the trick! Thanks so much to everyone, Later!

I just checked the Service Manual for the MP830 and there is no listing for an error code of 5C10. There is an error code for 5C00 and that is an error with the Purge unit. The error 6A00 is also and error with the positioning of the Purge unit.

The only thing you can try is to open the cover and see if the printhead will move to the center. If it does, use some rubber gloves and paper towels and see if the wiper blade is extended and stuck that way. Don't force anything. Just press down on the pads.

If the head will not move away from the lock position you have no other option except to atke the printer apart or take it to a Canon Service Center.

I got this error message on my printer, of course just two months after it came off warranty. I contacted Canon tech support, and they gave me a list of instructions, pretty much all about clearing a paper jam or bit of paper, and I know that was definitely not the problem. The only recourse they offered was to ship it to a repair center in another state, and because it is so heavy between the cost of shipping and cost of repair it's not worth it. Which leaves me free to tinker around with it, as I sure can't make it any worse than it is.

After spending some time trying to figure out what was going on, I recalled that I had opened a new black ink cartridge (the small one) and it had a big drop of ink plop out as I was putting it it in place. I printed a page or two and then got the 5110 error. It seems apparent the ink that dripped out is the culprit.

I'm going to start with taking out the cartridges and checking the cartridge head, and if there is any ink on that I will try cleaning it with alcohol. I'm also going to toss the black cartridge that leaked and put in a new one.

Does any one have advice about cleaning the track that the cartridge slides across, if I should find any ink on that? Is it OK to clean it with alcohol, or should I use something else to clean it? Does it need to have any type of lubrication applied after cleaning, and if so what? A silicone type or something else?

Any help would be most appreciated. It's a good printer and if I can tinker it back to performing it would be nice.

Thanks in advance!

I've gotten multiple errors tonight... in this order:


So I can definitely verify there's such an error as 5C10. I'm using a mac if that is a factor.

I was able to move the purge unit back and forth quite a bit and thought I cleared it, but still had an error afterwards. Now I can't get the purge unit to move that far. Extremely frustrating as this is a few months out of warranty, but I'm not even sure when I bought it.

flotsette,... I see that you have been through the gamit of errors on this printer. If you have moved the purge unit pads and got it out of one error into another, I don't think you have much choice except to take it all apart and get down to the basic parts. You can't believe how many parts are moving inside that little purge unit. There are multiple gears, arms, levers, valves, a vacuum pump, suction pads, photocells, cams, springs, wiper blades, DC motors, etc. If anyone of them is out of place or broken, the purge unit cannot cycle correctly and as a result the logic card expects the correct timing signals back from the purge unit each time the power is turned on.

I sell a Repair Manual that will teach you how to take it apart and get at each part inside. You may be able to fix it if it is only a gear out of sync, or you can buy a replacement part from Canon. They have them all.

Click on my USER ID and send me an email. Once I get that I can send you back the information on how to get a manual.
by unknown on Jan 25, 2009 at 10:43pm Add comment
DeniseE,... I check on the 5100 error and it is the basic 2 flashes of the orange light, then a temporary green. The is a carriage error and has to do with 4 possible problems.

- Carriage unit
- Timing slit film
- Logic board ass'y
- Carriage motor

It could be something as simple as the Timing slit film, which runs through the back of the printhead, has come loose from one end and is dangling inside the printer. It could also just be dirty with ink splatters. It could be the Carriage drive motor, or the drive belt, or just a bad photo sensor. The worst possilbe fault would be if it is a bad logic card. In all the printers I have worked on, I have yet to find a bad logic card.

I don't know if you are inclined to do repair work on your printer. If you have to take it to a Canon Service Center, it is going to cost you $$$ because these large Multifunction printers are timing consuming to take apart and repair.

If you are interested, I sell Detailed Repair Manuals for these printers that will show you step by step now to take it apart and find or fix the problem. Just send me an email if you are interested by clicking on my USER ID. Once I get the email I will send back the information.

Mr,... A,... I think what you are trying to say, with too few words, "When I open the top cover of my Multifunction MP830 printer, the Carriage, Printhead, and ink carts no longer come to the center such that I can replace an empty ink cart". Of course there is some other error posted on the small display and with my Crystal Ball, I can see from here that it says, "Error 6A00".

This is the AP motor error from the Purge unit indicating that your purge unit did not complete a full cycle. As a result the purge unit still has the printhead and Carriage ASM locked in the far right "Park" position. Sooooo the only solution for you is to take the printer apart.

There is one "Despriate Trick" you can try, but it has less than a 1\% chance of working. You may have to try this 5 times and see if you get lucky.

This entire process will have to be repeated, not just part of it, if your are going to get lucky.
1. Pull the power cord and allow internal memory to discharge and loose memory. This takes about 3-4 minutes
2. Plug the power back in
3. With the Cover open, press the main power button.
4. Count to 5 and pull the power cord out.
5. Wait 30 seconds.
6. Check to see if the printhead has moved ANY AMOUNT AWAY FROM THE PARKED POSITION, OR IF YOU CAN MOVE IT BY HAND WITH VERY LITTLE FORCE. This means you should not use any excessive force.
7. If it moved you are lucky as you are now able to move it to the far left of the printer such that you have access to the purge unit. With access you can try to see if you can un-jam the white plastic wiper blades, as this is 75\% of the cause of all purge unit jams. Press the ink pads down gently and see if they are free to move down at least 1/4 to 1/2 inch. If you think you freed up anything, close the cover and re-plug the power and see what you get.
8. If all of item 6 & 7 failed, go back to step 1 and start over. Then when you get to step 4 change to wait to 8 seconds. The next time change it to 3 seconds. The next time change it to 10 seconds. The last time change it to 1 second. Now you can give up.

What you were trying to to was to catch the purge unit in its normal power on test cycle were it moved through all physical positions. In one of those positions it drops the locking tab on the printhead for just a second or more. If you were able to pull the power at that exact time, you would be able to move the printhead once the power is removed. While the power is on, the printhead carriage drive motor is active and will NEVER EVER LET THE PRINTHEAD MOVE WITH POWER ON.

Sometimes this works, sometimes it doesn't. Good luck

Thanks to the person who suggested manually moving the cartridge head to the far left and using a "torch" (flashlight)to look to the far right. I found a torn piece of paper jammed there which, when removed, solved the problem.

Happy Pixma User,... That would have been my suggestion about 10+ post above. It is just a simple thing but I've worked on so many of these and I know how difficult it is to see in there, especially on all of the Multifuntion unit. I don't know why they make it so difficult to get into the printhead and replace the inks. They started making it more difficult after the iP5000 units. The iP4200 was the beginning of standard printers where they restricted access to just the center. I guess now that I look back at even the older printers they all had very little top door to open to get at replacing the ink.

The Purge unit is such an important part of every printer you would think they would make it easy to get at so it could be cleaned. I guess I just WALKED over the answer,..."They don't want you cleaning anything or messing with anything inside and if they can keep it out of view, then you would probably have no choice but to take it into a repair location and spend more than it cost to get it fixed.

Anyway, I'm glad you got it fixed. Remember to do some regular maintenance, print a nozzle check once a week, and never turn your printer off. YOu will save ink if you do all of this.

Found the fix here.

I removed the ink cartridges. Used a gentle "natural" household cleaner to spray inside the ink holder and the bay to the right. Paper toweled it up. Turned my machine back on and it works. Error message is gone. Must have been dried up ink. I found no paper stuck either.

Olsondog,... I'm glad you got yours to work,...however I would never use most holdhold cleaners. Most of them have VERY corrosive agents and can eat up all kinds of parts. Just above where you sprayed is the very end mark for the timing strip. If that gets anything on it, the printer can not CONFIRM the home position. The best thing to use is Hot Water, or Windex. The wiper blade on top of the purge unit goes all the way under the Black and color print nozzles and WIPES any excess ink off of them. Then it bumps into a plate just past the head where it is supposed to go past. Then the drive to the blade is removed and a SPRING is supposed to snap the wiper blade backward and "Flip" all the excess ink off of it before it goes backwards and wipes the head again on the return trip. After 100's of these operations, the inks accumulates so much and drys it becomes very sticky. One day when it passes the head it just sticks there because the spring is just not strong enough to break it. AFter this, if it sits like this for awhile, and the printer is turned on or tries to print, the purge unit will get an error since the wiper blade is in the wrong position,...ie. stuck extended.

Just a narrow spray of hot water or just touching the wiper blade will free it so it will snap back in place. However, it will stick again some day if you don't really clean it good.

Hi everyone, i had an mp800 series with 6A00 error, after a paper jam, I moved ink head to the left, and manually pushed the capping mech ( on right hand side ) back into place, powered up and it went , problem solved

Anonymous,... Great,... you are one of the lucky ones, your jam was not so bad since you were able to move the head as I had instructed many notes above. You have it un-stuck right now but I suggest that you take the time to try and clean as much of the junk ink off of all those parts as you can. Otherwise it will just stick again on you again. Maybe next time you won't be able to move.

Good luck

Canon printers seem to be poorly made.
I've had a couple of issues with my near new MP800, including having to buy a new print head.

Anonymous,... In my experience, you may have been unlucky and somehow ended up with a bad printhead. However, most of my experience has convinced me that 97\% of these failures are the result of poor printer maintenance.

I repair all types of printers and I can tell you without hesitation that Canon is the ABSOLUTE best of them all. Any modern day electronic printer can have problem, but if you search the internet and a couple of specific sites, and tally up the list of problems you find from people all over the world, you will find that HP printers are the worst bar far, and Epson is the next, and Canon is the last. The other printer MFG. are even worse than HP. HP does not create or make availbe any form of Service Manual for any of their printer. The don't have a Service Department or a Part Department, and they don't sell parts. Their line of printers are designed to fail in just over 1 year which is their warranty period. Why would they do this,.. why have a repair or service manual when you don't have any places that will do service since there are no spare parts.

What if you bought a car and found out the no one would ever service it since there were no training, no manuals, no parts. Soon you would get the idea they don't care. Epson is just about the same since there are very few Service Manuals and I can never find anyone that will sell the parts.

Canon has created detailed Service Manuals for every printer they have every made. They also will sell parts for just about every printer they have every made going back to the 90's. How do I know this,... I repair printers. I have just about every Service Manual Canon has published, and I buy spare parts for them all the time by just calling their Parts department, which sells parts cheaper than those you can find on the internet. Since I repair these everyday, I know they are designed for ease of service. I'm still fixing Canon printers that are almost 10 years old and they work terrific. They are so well designed there are very few parts that will even wear out. The major failure rate of any printer is the printhead and as I have indicated above, 97\% of the failures are the cause of the owner not taking proper care of the printers. Maintenance for these printers is very simple.

1. Never turn your printer off,.. you will use less ink.
2. Print a nozzle check every other day or at least once a week
3. If any tiny ink jet clogs show up, clean the head in the service section or use a color purge chart.
4. Use only the best ink if you refill your own ink.
5. Keep the ink carts clean and check them for ink flow
6. Print a nozzle check before you start to print a quality photo.
7. Clean the printer and the purge station of all dust, excess ink, dirt, coffee stains, paper clips, bits of paper, etc.
8. Never use UNIVERSAL INK, as there is no such animal. It is only junk that will eventually glog your printhead and give you trouble.

Thank you to all the people who make a serious attempt on this site,to help others with problems.I have a Pixma MP810,which I find to be a fine product.But last night, urgent little print job on hand I started.Suddenly moments later,grinding ratchets and flashing lights it came to a stop.Error 6A00."WHATS THIS" No electronics experiance (retired builder)I need help. Research in the manual came up with no reference to the error, except to send it in for service.Problem!pension = money tight.So take a look myself.I removed the print papers and opened the lids,(access to ink tanks)"Oh Oh" There we are.One kleenex type tissue shredded in the works.Bits everywhere.This might be whats up.A cleaning wipe, accidentally found its way into the paper feed somehow I'd say.I cleaned out as best I could, and tried to restart to no avail. Still error 6A00,A quick search "On Line" brought me to this great site.After reading through the suggestions I tried again with help from "not so young" son.We found by removing ink tanks first,a small lever type lock on right of carriage allowed it to be lifted out, It can be slid across to side but this allowed clear access to the works.(Don't forget I had bits everywhere!)Next very carefull use of the vacume cleaner with the long pointed nozzel worked wonders. Through the front, down the paper shute, and in through the access door on the back.Next I think it is refered to as the purge unit.A small sliding sponge wipe unit with a plastic face, sitting on the right side of where the ink carriage rests in the center.It's supposed to slide back and forth,resting at the back.Mine was stuck in the forward position.A gentle push with the end of a screwdriver,It popped back and released a large lump of ink satturated tissue it must have dragged into itself.So reasemble ink carriage and tanks and try again."GUESS WHAT" no more problem.We put the machine into self clean cycle and fed a couple of papers through. Then a print check cycle to check alignments etc and so far good as new.So maybe there is hope for us tryhards. Not much money.But good help from "FRIENDS". Note. Beware of items falling into access shute.. GOOD LUCK TO ALL.

bugsy.t,... Congratulations. There have been many excellent posts to this web site on all kinds of printers. You are a great example of how these things can help. However, I will say you were also very lucky. The jam could have been much worse and you may of had to take the machine apart. The Canon Multifucntion machines are great products, but they are very complex, and there is a lot to take apart. However, the Canon printers are well designed and are rugged and can handle all kinds of jams.

Now all you have to do is find that person the dropped a kleenex in the paper feed.....Meow!

There have been tantalizing references above about taking machines apart, at least partially. So hopefully this is relevant here:
I have a Pixma MP810, about two years old, and it appears to run poorly when iPod headphones are run thru it (I blame the kids). They - the headphones - fell into the Auto sheet feeder. The problem is that even tho most got removed, the power jack is still in there. I can see it from underneath, if the paper cassette is removed, and the little green plastic flap is pulled away... but I can't pull it out from there, or see it from any other angle. Does anyone know how I can take apart as little as possible to get at the little devil?

Mike,.. I have the instructions on how to take this printer apart so you can get at the XXXXX. Click on my USER ID and send me an email so we can communicate. I'll send you the details of what my Repair Manuals cost.

If you take it to a Canon Service Depot, that may have to charge you $100 because the effort to take it apart is VERY Labor intensive, even for a trained person. However you will be able to do it since my instructions are step by step. It will just take you several hours to take it apart and the same to put it back together,...so it will work again.

Hi Trigger,
I have a Canon MP620 and display shows U130 .... ink cannot be detected ...... replace ink tank. Cartridges are quite full. And printer refuse to work. Earlier message was ink level low but printer could still print.
Please help. - Anonymous
My problem seems to be a little different than everyone. The print gets skewed when using black, and it does it in the same place/column every time all the way down the page. Anyone seen that before?

*** NEVER MIND! I was just finishing up cleaning everything, like the purge area, etc. that y'all mentioned in previous posts, plus the timing slit tape. After all that and praying too, it prints like it's supposed to.

I got this same code on a PIXMA MP530. Thanks so much for this thread! People, check the thing they're talking about, the purge tank. I moved mine back and forth and found a paper clip in there! After turning off and on again, everything works normally.

Now why can't Canon just tell me that via email? What a greedy corporation to want me to travel 80+ miles to get it fixed or buy a new one. This code is simple to fix if they would just tell us!!!

Landon,...It isn't always that easy. Of course they are not going to open their mouth because they believe that only persons trained by them are capable of "Fixing your own Printer". Canon is no where near as bad as HP, Lexmark, or Epson. I work on and repair all of them and I will tell you that Canon printers are the best of all for a lot of different reasons.

I had the 5100 part of the issue and wiped the encoder down a bunch of times. It had a bunch of grease on it from the ham-handed idiot that I had bought it from. He had gooped this thing up something awful and it wouldn't properly read the position. I also did a minor version of what you suggested on the purge unit (I just sopped up the ink that came easily).

The unit now functions flawlessly!!

BIG THANKS FOR GETTING ME TO GO IN AND DO THAT (everything I did was inspired by this post)!!!!!!!!!

I would like to add my 3cents to the last comment. Some people have problems with Canon, some have problems with HP, or Lexmark, or Epson. None of these machines are perfect but IMHO, Canon is bar far the best. I say this for many reasons.
1. I have worked on and repaired a large number of printers and Canon is the easist to take apart and repair.
2. To get a feel for how many people have problems with each brand of printers, just use this web site. Start at the "Ink Jet Forum and just count how many posts or problems are listed fore each printer type. There is no doubt that HP will have the largest number.
3. HP used to be a great company for printers and other products. Then a few years back a Lady took control of the corp. and changed many things about the product development. All of this was intended to increase their market share and their revenue. The original owners, Mr. Hewlett and Mr. Packard, strongly objected to what she was doing but it was too late as she had control over the board of directors.

Her policies changed the core beliefs of the corp. They stopped designing things to be repaired. They stopped making spare parts, they stopped creating Service Manuals. The printers were designed to last at least for the warranty period of 1 year. Since there are no spare parts or Service Manuals or stores that offer to fix any HP printer, the only choice for customers was to "BUY A NEW PRINTER", when theirs failed.

I have over 50 printers in my shop for repair and 2/3 of them are HP printers. It is virtually impossible to get any replacement part for anyone of them.

I have fixed over 50 Canon printers, I have the Service Manuals for virtually every printer Canon has made in the last 10 years. All I have to do to get a new part is call the Canon Parts department. They still keep parts for printers that are 10 years old. I have yet to find a Canon printer I can not repair.

The design of the HP printer is terrible. They are not DESIGNED to even be taken apart. Why,.. because HP wants you to throw the printer away and buy a new one.

Last but not least, the cost of HP ink is the most expensive. The other day I saw HP ink pack for sale at Sam's club. The color and Black ink carts -HP 95 -HP 96 where priced at $89 for the two. The HP95 only has 7ml of ink and the 96 has 20ml. A Canon in cart sells for $15 and has 12ml of ink. You do the math.

Hello Again,
I would like to thank everyone who has contributed to the 6A00 error code problem on the MP830, especially trigger1937.
After trying everything listed here I finally got the cartridge out of the parked position by using the following method. I opened the cover and turned the printer on and while it was trying to move the cartridge assembly to the center (going through all of the mechanized motions) I pushed the cartridge assembly to the RIGHT instead of to the left.
I heard something click and the cartridge was released! It is now working fine as if nothing ever happened.
Thanks again trigger1937 for your excellent advice.
by john 767 on Apr 29, 2009 at 5:47pm Add comment
I have communicated with John and would like to add my comments to his effort. While this worked for John, I would not recommend this to anyone as a first effort. When power is on the drive motor for the carriage ALWAYS HOLDS AND CONTROLS THE POSITION OF THE CARRIAGE ASM. Pushing the Carriage to the right while it was stuck at the purge unit has the possibility of stripping the drive belt or damaging the drive motor.

As I explained to John, the Carriage asm and the purge unit are totally independant in both electrical controls and mechanical movement. You should never try and move the Carriage in any direction if the power is still on.

What probably happened for john is; 1. The Carriage and the Purge unit were already jammed together in some way. My guess is that the Wiper blades got stuck extended on the previous operation and when the Carriage returned to the park position it jammed into and locked with the Wiper blades. John got lucky in that when he put pressure on the Carriage to try and move it to the right this must have released the wiper blades and since they are held to the rear by a long spring, it snapped back in place and the jam was cleared.

2. Another way to accomplish the same effort would be to push to the right on the carriage asm while the power is off, then turn the power on at the same time and as soon as the internal cycling starts, remove the pressure on the Carrige.

3. If all of these fail, then there is a way to do what John did without really hurting anything. Since the Carriage and the Purge unit are already jammed, I don't think it will hurt anything if you a small amount of pressure to the right. In this position the carriage is not going to go far anyway so some amount of press can interrupt the jam. The jam is caused by the Carriage trying to move to the left but is hung up on the extended wiper blades. There are no other parts that can catch the underside of the carriage, EXCEPT AN EXTENDED WIPE BLADE.

I hope this helps and does not hurt.

Sometimes we get lucky and things just work. However, I bet there is someone out there still Mad as @#$\%#@@ because it didn't work for them.

The problem may be something much more complex. The purge unit is one of the most important units in the printer and it has dozens of parts that can go wrong, especially one that has had a lot of use because the owner doesn't know the best way to take care of a printer.

If there are others out there still having 6A00 errors, post a requests for help and explain your symptoms and what you have tried and the results.

I now have a black finger and a printer (MP960) that works.

I felt it go down and turned the power on. THE PRINTER WORKS, THANKS!

got an MP530 Cannon with same 6A00 error....

no response from the ink carriage but it moved freely.
no paper jams or feed problems.

out of desperation, I took an old rag and cleaned the head cleaner section - it's on the left side and looks like a couple of fiber pads.

it had ink gunk, paper fibers, and crap all over and around it.

this fixed the problem.

I used an old t-shirt rag - avoid anything fibrous like terry-cloth...

this is a messy job no matter what you do, I suggest latex or nitril gloves to save your fingers the stains.

had a printer tech tell me the best thing to use to clean the pads is regular windex window cleaner to get the pads really clean.

this section keeps your heads clean so if your having printing issues that would be the first place I'd clean and service.

Our Canon MP830 recently experienced the dreaded 6A00 code. I read most of the posts on here, which gave me many suggestions. Pressing down the purge sponges. Sliding the purge assy wiper. Etc. I wasnt as lucky as alot of you. I did notice i couldnt smoothly turn the purge assy pump gear. Hmmmmm

So I bought s service manual online. Not as helpful as I was hoping it would be. It did show me the official cause for the code. AP position error. AP position is monitored by an optical sensor on the purge assy itself. So it makes sense for the 3 possible causes.

1. Sheet feeder unit: Why? As i found out upon disassembly, it drives the purge unit. I was ok there.

2. Logic Board: It monitors the optical sensor, which monitors the purge assy position. Was it the cause? I doubted it.

3. Purge Assy: As some of the techs on here have shared, this was probably the culprit. they were right. I disassembled the printer, which was quite easy. take digital pics occasionally to document your progress. particularly the logic board, and the position and routing of the ribbon cables. There are several toroids (magnetic rings) all over the place, so a pic helps with the reassembly.

Ok with the purge assy in my hands, i still didnt know what the heck i was looking at. I studied it a bit and here is what i found. the purge assy contains the following components. the drive gear- driven by the sheet feeder unit. a cam assy which- 1. drives the wiper (many of you have been sucessful my sliding this wiper) 2. drives two mini air pumps (one for color, and one for black) 3. and the position disc (where the sensor picks up the purge assy position). the slide- basically has a couple of squeegees that clean off the bottom on the print head. the waste ink absorber- this crazy thing goes up and down (with the beforementioned cam) and has a couple of sponge-like plates that the ink goes into from the print head. ok, follow a series of gears to the last component. it looks like a motor, but it a pump.

this pump was my problem. it has two chambers. one for color, and one for black. the two inlets for the pump comes from the ink absorber via small rubber hoses. inside each chamber is a piece of very flexible tubing wound around the inside of the chamber. a roller on an eccentric (offset) basically massages the tubing to cause a pumping action. the outlets from the pump direct the unused ink to two different locations. the color goes underneath the purge assy. the black goes under the sheet feeder. our printer was almost two years old, and you wouldnt beleive how much ink was in there.

ok back to my problem. one of the rollers had come out of position and locked up the pump assy. i repositioned the roller, and reassembled the printer to the return of printing bliss.

a quick way the check if something is locked up, is to power off the printer, and manually move the printhead to the left. on the far side of the purge assy, the is a partially exposed gear. you should be able to move this gear smoothly and watch the purge assy work. it should raise and lower the ink absorbers, and advance and retract the slider. it will repeat those actions indefinetly.

why document all of this. just giving back. alot of people on here have helped me.

Hi Landwerlen,
Thanks for taking some of the mystery out of the dreaded 6A00 error code and for the thorough description of the pump assembly!
John - john 767
I have a Pixma IP5000. Got the error message "6A00." Nothing in the manual about how to fix it. The whole darn thing just stopped working. I found this list by google. I pressed down very lightly on the sponge tray area described by Anonymous w/a pencil. It moved the tray down locking it into a lower position. I slide the print head, ink tanks back over their normal resting place, all to the right. I closed it all up again. Turned it back on again and Voilà!! It's working. Thanx Anonymous.

Anonymous U130.. Many Canon printers come up with this same error. You must be refilling your ink carts which is ok. Open the cover and after the head is in the center, pull out the power cord and wait for 5 minutes and then put it back. Then close the cover and power the printer back on.

This worked on my daughters MP530. If it does not work I suggest that you go online and purchase a Canon CLI-8 chip resetter. They are typically about $28 and will reset the ink monitor to show the inks are new and full. Each time you refill your ink you should use the Chip resetter.

The printer (a Pixma IP5000) continues to work just fine w/the aforementioned "repair" for error message 6A00; just slide the print head/ink to the left, gently push down on the sponge (tray) which is under the normal print head/ink resting place on the right, then move the head/ink back to the right/resting place, close it up and turn it back on... easily done.

you guys ROCK!!!. I have never fixed anything like this in my life. And I was having a terrible day as everything in my house seems to be breaking. Then I go to print and that is broke to. But I did everything suggested, and finally it worked. Thank you all!!!

had the same problem with mp 970.

i moved the printhead to the left, and pushed a small black piece in front of a white one with white print sprinkles on it down ( you should not need a big amount of pressure ) worked out just fine - everything was ok.

thanks for your help!

Thanks guys. Sorted out the problem. The tip to move the white 'paddle' that sits over the square sponge was spot on.

Moved printer head all the way to left put on rubber gloves and used a paper towel on the right side where printer head stays. Reset printer head onto the right side and finally it lit up again and moved on its own....Thanks again this thread helped out greatly...

I too had the following symptoms and I solved it :)
#357 error
flashing alarm light
ink carriage would not move to center but could manually

I was about to take it apart because various posts had suggested taking the right side off might allow me to re-connect the carriage or put it back on the belt. Since it moved freely by hand, I read the belt is likely broken. That was NOT true in my case.
Solution: physically unplugged machine for FULL 60 seconds.
looked closely around inside as I move carriage back and forth: found sticky note. after turned on - printed a few papers - still bad clicking sound until finally the other half of the sticky note came out with one sheet printing. Works great now. Good luck.

In looking at the posts in this MP800 thread, I see a consideralbe number of people with MP800 printers and most all of them having good success in finding and fixing their problems.

I'm looking to trade information on the MP800. As many of you know by using this forum I have created a series of Repair Munuals for almost all of the Canon printers. Once that I am missing is the MP800, only becuase I have never been given one to repair. If any of you have any detailed pictures of the disassembly process you have used I would be willing to trade any one of my other Canon Repair Manuals for those pictures. I will also include the Canon Service Manual for the MP800.

I'm specifically looking for pictures of the 4 screw locations that hold the printer asm in the base. I already have detailed
pictures of the MP450, MP500, MP600, MP700, 710, 760, 780, and the 4 screws in all of these are basically in the same place. However, I never want to assume that Canon did not make a significant change which would certainly confuse anyone reading one of my Manuals.

So if you want to make a trade, or if you have a question about you MP800, just click on my USER ID and send me an email.

Hi trigger1937, I hope I find you well. I haven't been using my printer for sometime now. I turned it own yesterday and now it gives me an error code 5110 and I do not know where to start.
Can you help me please.

Thanks in advance

I have an MP830 with the 6A00 error and, after trying everything in this thread without clearing the problem, I am starting to dis-assemble the machine so that I can get to the purge station. Any help would be appreciated. I would be happy to take any pictures you need during the process.

N.B. Although long, this is not yet a success story!!
I, think trigger 1937 is right, walking away from Canon because something goes wrong, doesn't mean the grass will be greener elsewhere. In my case, when my PIXMA iP5200R quietly signalled a 6A00 'AP position error' fault during an uneventful run of 6 x 4 photo prints a week or more ago, I had had good service out of it and so, in extremis, would have bought another. But Canon seem to have shrunk their offerings down to the iP4600 only in this class of machine - and, for a variety of strong reasons, the iP5200R fits in with my useage like no other on the market that I can find. So I consulted this and other forums, got the PDF's of the Service Manual and Parts Catalog and dismounted, examined and cleaned the purge unit. I re-installed it, having checked by hand that it appeared to be functioning mechanically without fault and re-assembled the machine. On re-starting the fault signal remains the same in both User and Service modes! Heigh-ho!
Diligent searching of the dismountd machine did not find anything in the paper path either. I shall, of course, not give up. It seems probable that the whole mechanism must be self-synchronizing - but, could I have possibly upset the registration of the purge unit drive with the main gear train? Advice, particularly about this and the several opto-position switches in the machine, would be welcome!

Seejeep,... Congratulations,... very few people have the patients or the technical skill to take apart any of the Canon All in one
printers. I encourage you to continue the search as this is one of the most common problem. It also seems to have been fixed many different ways. Because I create Repair Manuals or all of the Canon ink jet printer family, I work to isolate these errors and there solutions. Therefore I am willing to work with you to find the fix.

With trigger 1937's encouragement I dismantled my (now nice clean) iP5200R again and got the purge unit out. It still checked out OK - but before re-installing it I managed to rotate the paper feed mechanism by hand a bit (using such exposed gears as there were touchable around the machine) and made sure that the moveable gear (which in part of the operation puts drive into the purge unit), was at a part of the cycle where it was in a withdrawn (non-engaged) position. Re-assembled and, (thank goodness!) after switching on and about 30-40 seconds of (non-threatening) grumbling, eventually proper operation was restored with no 6A00 signalled. As a tribute to the design (and my own dismantling care!) on testing I found that no aspect of the printer's operation had changed. So I feel lucky.
Anyway, the probable original cause was, almost certainly, the well-established one of 'something not right in the purge unit'. The second failure (which I reported to this forum), I've put down to an unlucky chance in re-assembling the unit into the drive chain, which probably prevented the mechanism from auto-aligning itself. As a matter of record, it may not have been a coincidence that the waste ink quantity (which the machine tot's up in it's memory) is shown as 41\%. (Canon say if over 7\% change the ink absorbtion pads!). So that's at least another another £16 I need to spend.
My thanks to trigger 1937 for the successful outcome!

Seajeep and I have worked very close on his iP5200R printer, but I will be the first to congratulate him on his courious nature and investigative skills. All that I was able to do was encourage him and add a few suggestions. He has returned any help I have given him 10 fold by supplying me with the detailed pictures he has taken of all of the effort.

In return I am supplying him a free copy of my iP4200 Repair Manual since I have not finished the iP5200 (never having one) and the two printers are very close.

My daughter has had this Canon MP830 for about 18 mths with only lite home use. Made a copy without any problem, then when going to Print Option, got this frustrating Error Code 6A00 and couldn't shut off machine, so had to unplug it. Contacted Canon Tech to find out what this code stood for (User Guide Useless) and was told, Paper-Jam or Purge Unit (but had no idea what Purge Unit was at the point). Throughly checked paper paths - even though I was sure that wasn't the problem, since work never got stuck and all copies came out as full sheets - and all was clear. Tried pushing Reset, Reset and On/Stop to RESET machine but to no avail. Then googled this ERROR and found this Forum. Read all the posts and tried the following which failed to correct error:
1 - With machine uplugged, Raised Top and gently moved Printhead Assmy far to left.
2 - Using small flashlight, tried to wipe off excess Ink from Far Right Front Wiper and Rear Wiper and gently moved them and inspected to make sure they appeared to be in place and working. Tested machine, but no change.
3 - Repeated Step 2 above using Windex and paper towels, moved Right Front Wiper up and down and Rear Wiper back and forth with out any difficulties and they appeared to be in good working order and mostly clean.
4 - Dabbed Sponge on Waste Pads repeatedly with folded paper towels, then using Windex and Paper Towels, dabbed Sponge many more times until it appeared almost White (was initally dark gray). Pushed assmy down and up easily without any difficulties and SPONGE appeared it to be in place.
5 - Inspected every section using a small mirror and flashlight to assist and rechecked Wipers and Waste Pad Sponge for movement. All appeared to be working fine and no debri was present.
6 - Removed all Ink Cart and wiped excess ink from each small inlet on upper part of Printhead, Cleaned each to insure no excess ink, checked chip contacts and re-installed all. Then re-positioned Printhead Assmy to Far Right - as far as it would go. Appeared to go all the way without any difficulties.
7 - Lowed Top, Plugged in, and while holding Reset, pushed On/Stop Button, then released Reset. Machine went through first part of warm-up as before and Error Code 6A00 reappeared - AGAIN!
8 - Tried repeating holding Reset and Pushing On/Stop Button to RESET machine, but to no avail. Machine just keeps repeating Initial Warm-up attempt, Alarm/Stop, and upon pushing On/Off Button, a long, load piercing - da, da, da - sound. Then recycles and tries to start again repeatedly until I unplug it.
9 - NOTE: Printhead assmy never moves (except for a little up/down movement) and it is always easy to move by hand. I've tried different placement positions for RESTARTING in an effort to RESET the Machine and hopefully get rid of ERROR CODE, but to no avail.
10 - Now I'm at a lose as to what to do because I didn't want to disassemble it without any knowledge of how it came apart for fear of damaging parts. It Doesn't appear that Canon wants non-experts to do their own repairs. So, it looks like I'll have to take it in for a $140-? repair bill on a $240 machine. Duh!!!!
Was just going to dump it and get another HP - like I had refore this one which lasted well over 5 years with no problems until the belt broke and I wasn't able to find a replacement anywhere - but after reading Trigger's post, decided to just get this one repaired. (Trigger - I've requested info about your Service Manual, so If I get that, might go that way since I and my daught both many this same Canon Model. Reviews WERE EXCELLENT BEFORE I PURCHASED, but I'm not so sure about there REALLITY. Too many 6A00 Errors, Inks To Expensive with little cart, and Warm-up takes too long before printing - making casual printing slow.

If anyone has any Ideas about what to try next to FIX this Error Code 6A00, I'd appreciate the Info since this is my Daughter's machine and she's been out of work since Sept 08 and money is tight.) I'm just glad we're not driving cars made by Canon, or we'd be walking!!!! Thanks, Pianosax.

Pianosax - Your obviously thorough reading of this thread will have told you that you were probably doing the right thing insofar as you could. And my experience with another Canon machine (see above) illustrates that, despite appearences, the problem probably DOES lie in some restriction whichhas developed in the purge unit. You will also note that my dismantling also created a (temporary) secondary problem!!

Dismantling is a matter of knowledge, organisation and practice really - so most, but not all, people should not try it. I started at 14 with my bike's freewheel mechanism in the middle of the back lawn! (I did get it back working before the folks came home - minus an apparently non-essential ball-bearing or two!).

Nevertheless - should you want a bit better access to the purge unit, the machine's Service Manual will probably show you how to take the covers off and on. The S.M IS available on some sites FREE - try Googling "PIXMA MP830 Service manual" or similar.

Above all, though, in this thread listen to Trigger1937 if he replies.

I've tried locating a REPAIR OR SERVICE MANUAL for the Canon MP830, but all I've been able to find is Guide Manuals listed as Service Manuals once I click on a Website after 'googling' Service Manual (or Repair Manual) for Canon MP830! Two sites wouldn't even come-up, just a ERROR - such as, www.asm-service-manual.com. I already have that and it is pretty useless when trying to "fix" a problem. Canon doesn't even list the 6A00 error, among others, but I've sure if they did all it would say is to take it in to a Canon Service Center. I'm trying to get info from Trigger on how to get his, but if you know of a Website that actually has a Repair Manual, please advise. Thank You. Pianosax - Anonymous

Anonymous,... Typically there are only two things to cause the purge unit to stick. One of them is dried up ink which has turned to glue, and the other is that a spring has come off or a gear is jammed.

To test the glue theory, load some warm water into a syringe with a very long needle and wet as many of the parts of the purge unit as you can, especially the wiper blades. Then wet and saturate both parking pads. then do a couple of power on/off cycles such that the purge unit will suck the water down to the waste ink pads. Press down on the two pads and see if they move. The could be holding the wiper blades extended and this is what is causing the jam.

Anonymous,... While your intended information was correct, you basic directions are not correct. If you just turn the power off the printer will return the printhead to the HOME position and LOCK the carriage and the printhead in that position.

The correct way to do this is to open the cover and when the printhead comes to the center, PULL THE POWER CORD OUT. Now you can freely move the printhead out of your way and proceed.

If you try to move the carriage with the power on, it WILL NOT MOVE, as it is held in place by the carriage drive motor and the drive belt. It will be LOCKED in place.

I stand corrected-I thought I first turned the power off and it was not locked (but then this is an IP5000). I'm old-hard to remember... Thanx for the reminder. :-)) Hope it works for this fellow. - Anonymous
Anonymous,... Yes I'm still alive and kicking,... and yes I have fixed that problem and many more. Your printhead is jammed in the parked position because some component in the purge parking position did not retract. Basically you have had a train wreck with the collision of the printhead moving to the right very fast and the purge unit out of cycle and out of position. The purge unit is the mechanical system that sucks ink down through the ink carts and down into the printhead and "PRIMES" them with ink such that they can print. The purge unit parts move back to front and the printhead move right to left and back. Once they collide, you will have a pretty bad jam.

You can try this one thing, with the power off, open the top cover and with your thumb, press to the right on the carriage assembly, and at the same time turn the power on. As the printer attempts to cycle the purge unit press and release and press and release several times and hopefully you can disengage to two units. You don't have to press very hard, you are just trying to take the press off of the purge unit so it can slide back in place.

If this does not work after several attempts, you are proably going to have to disassemble the printer to physically get at the two jammed parts and free them. To do this you need one of my Repair Manuals. Click on my USER ID and send me an email and I will respond with information on how to get one.

We are always very happy when one of our suggestions helps someone fix there problem. However, the lesson to be learned is that this kind of problem would never happen if you did some proper maintenance on your printer. I can imagine that most of the purge units that get stuck extended are so covered with STICKY INK that anything that ever fell in that area would cause a jam.

My suggestion to everyone is,..."learn how to keep you printer in top working condition and how to clean it" You will be much happier for it.

My MP830 displayed 5c10, 5110, and A600 errors. I cleaned the purge system and all seems well except that I can not get the ink tank carriage to re-engage.

Ok I'll mention what happened to me. After printing some high quality photos. The printer started giving me this 6A00. I have been using this machine for over two years. I turned it off, but nothing happened. I disconnected all the cables from it, and turned it back on, it appeared as starting up normally and it finished without showing the error. But the error came back after trying to print a test page. After thoroughly reading this page, I was able to reach the purge unit and saw the small sponge that is supposed to be down. I pressed on it, did a little cleaning in the purge unit, and then moved back the print head to the far right. Turned it on and all is well.
Somebody here said that glossy photo papers are not supposed to be placed in the top feeder, and that's what I have been doing all the time. This might be the reason in my case.

I would like to 2nd the above suggestion. If you've fixed your printer problem because of some information you received, the best thing you can do to help others (and those of us that attempt to help) is to post what your problem was in some detail and then what you did to fix it.

Now,... for Amdarrah,... You said you cleaned the purge system and "ALL IS WELL",...except it isn't sense you still have the jam. The carriage won't move if a jam is stopping it or if the logic card diagnostics detects a jam in the lower part of the purge unit. What ever you did to clean the purge unit did not clear the jam. You may be forced to take the printer apart.

Anonymous,... The MP830 is as good as any other Canon MP. Their labor rate is typically $75 per hour and they know it takes several hours of trained time to take one of these apart, find the problem, get the replacement part, put it all back together, test it,...take it apart again because they forgot to connect a ground wire someplace, etc. etc. So the charge may end up to be $125++, they never know. What they do know is that many people won't pay that and just go out and buy another printer.

The 6A00 error is telling you that the purge unit is jammed or not finishing the complete cleaning cycle. Here is what you can do to find out. Open the cover and once the head comes to the center unplug the power cord. Now you can move the head a little more to the left and get at the purge. Use a folded paper towel and a flashlight to examine the purge wiper blades. Sometimes they get so covered with dried up sticky ink that they stick extended and you will get the 6A00 error. Wet the paper towel with hot water and clean off as much as you can reach. Check or anything that may be jammed in the mechanism, like a paper clip, staple, paper, etc. Press down gently on both of the ink pads where the printhead rests. Sometimes the Wiper blades are a little late in returning and they catch on these pads as the wiper returns to the rear of the machine.

Once you've done all of that plug the power back and turn it on. If you need to go to the next step of taking the printer apart, you're going to need one of my Repair Manuals. Click on my USER ID and send me an email and I will return information what is contained on one of my CD's and how you can get one.

I have a Canon MP830 and I am getting a 6a00 error. I noticed the purge unit was sticking. I checked to see if something is jamming and saw no foreign objects. I took the printer apart and removed the two sponges on the purge unit and cleaned them. I also cleaned the purged unit itself. I placed Windex where the sponges lay and noticed it was draining through the bottom holes. I repeated this process for a couple days. I also moved the ink carriage back and forth a few times. I put the printer in service mode and all the ink tanks lit up and no service code errors showed. I put the printer back together and it still gives me an error 6a00 and the purge unit is still sticking. I can manually move the purge unit by moving the gears but when the printer tries it sticks. Is it financially worth replacing the purge unit or should I start looking for a replacement printer? What would the approx. cost be for my printer to be serviced?

Anonymous,.. Wow,.. you did a terrific job. Getting one of those apart as far as you have done, without instructions in amazing. You are not a Certified Canon Repair Person.

If your purge unit is still sticking, it probably needed some lubricant. What part is sticking,... is it the wiper blades that extend forward to wipe the bottom of the head?,... Were you able to remove and clean the purge unit and inspect the very bottom.

If it is still sticking you need to find out why. This is the source of the 6A00 error. If it is defective, you can purchase one from Canon Parts Department for $28 including shipping.

Hi Trigger,

This is "Anonymous" I registered to this forum now. I am not a certified canon repair person but I spent 10 yrs as a Computer Technician so taking things apart comes naturally to me.

The purge unit is sticking in two places. It is sticking when it tries to move the wipers back and forth. Also the part that houses the sponges, it gets stuck going up and down. If I manually move the gears it does not go all the way forward or back. The gear stops at a point then I will move it in the opposite direction. I am not sure if that is normal.

I have not looked at the very bottom of the purge unit because I have not attempted to take the printer apart that far. I Windex'd the heck out of that area since I was at wits end and the worst that could happen is that I will need to buy a new printer. - sfloridmom
sfloridmom,.... I got your email and I will send the picture. It sounds like you were able to take the ADF and the top cover off as this is the only way you can get to the parts you cleaned. If you were able to manually cycle the purge unit through a complete cycle, that is some good news. On the rifht side of the purge unit (As shown in the pictures I sent you), you will see the white gear. YOU CAN ONLY CYCLE THE PURGE UNIT BY TURNING THAT GEAR IN THE DIRECTION OF THE BACK OF THE MACHINE. BE CAREFUL AS YOU TURN IT AS YOU DON'T WANT TO DAMAGE ANY GEAR. If you have cleaned everything with the Windex then it should not be sticking anywhere, and the pads should go down as the wiper blades come forward and once the blades snap back the pads will come back up as you continue to turn the gear.

I will also send you by email more information about my Repair Manuals and what they cost and how to get one. It contains the critical information on how to disassemble the rest of the machine and how to test it while it is apart, so you know it will work before you put it all back together. There is also many other things to check once you have it apart.

I have taken the cover off my MP800, but still can't find a way to move the carriage to the left. I removed the print head from the carriage, but I still couldn't see an obvious obstruction to the carriage moving. Is there a locking mechanism that holds the carriage in place when parked?

in answer to my own question, I manually turned the purge unit through a cycle which disengaged the carriage lock and hence I was able to move the carriage.

mejico,... now that you have the carriage out of the way you can examine the purge parking pads to see if they or the wiper blades are jammed. Cycle the gears by hand towards the rear of the printer and you should be able to take it all the way through one full cycle. Look to see if anything is jammed, like a paper clip, or pin, or anything.

I did it!!!! I've been weeks without a printer. After reading the posts here I was encouraged to continue working in my mp600. Finally, finally to the far right of the printer cartridge holder I discovered a black elastic hair band wedged in there. I win!

I have owned an MP800 for the last three years and have never experienced a problem until now - it refuses to scan.
I replaced my pc for a laptop running Vista and immediately was advised that the MP800 software was incompatible - I was advised to acquire some additional software which I downloaded and all seemed fine until I tried to scan some drawings recently - the display on the printer follows the normal sequence and does not suggest any kind of error, just refuses to respond once I reach the 'press print button to scan'.
Anybody know the answer?

I agree with several people here. I took a flashlight and looked inside and what did i find? A small hook that have falled down from the wall and inside the printer :) A small tweezer to get it out and now I can print again! Check inside your printer before you send it to a repairman people

Sorry, I thought my post was going to show up under the post I was replying to so others would know what I was talking about. Anyways, I have a Canon Pixma MP830 that was showing the Error 6A00 and I followed the advice of turning off the power, sliding the ink cartidge "carrier" over to the left, and pushing back the ink sponge into place. The sponge was lifted but it slipped back into place without any effort...I was actually still trying to find out where it needed to move to but as soon as I touched it, it slipped down into into a spot where I assume it belongs because my printer worked fine afterwards. - Anonymous
it dont work, error code is 41

Trigger1397, firstly thanks for your reply. I was able to manually cycle through the purge cycle, no problems, so I reassembles the printer and all was fine for a week or so then the problem re-occurred so I took the printer appart again and this time I cleaned the pads and as much of the purge unit I could get too with some Isopropil alcohol. All was ok for a test run but next time I went to use the printer (about a week later I got the dreaded 6A00 again. I have checked and there is nothing jammed or in the way, I suspect it's coagulating ink that's the problem, I read somewhere else that using a strong nappysan solution is the best way to clean the purge unit. I wasn't sure about that as I wanted to avoid the use of a water based solvent.

Addendum: I forgot to mention in my last post that when I cleaned the purge unit, both 'sponges' lifted straight out as if they where just held in place by gravity without any adhesive. Is that what it's meant to be like or are the sponges meant to be glued in place?
by mejico on Dec 19, 2009 at 12:48pm Add comment
mejico,... They are typically held in place but they can be lifted out and cleaned. These are very thin stiff sponges which mate with the bottom of the printhead nozzles and the other side mates with the suction tube of the purge unit. The suction is distrubuted through the sponge to pull ink from all of the nozzles at the bottom of the printhead. The suction depends on all of the little pockets in the sponge to be wet and full with ink. The vescocity of the ink maintains the vacuum of the suction and pulls the ink down out of the ink pads into the printhead and then down through the purge tubes into the waste ink pads.

Put them back in place and it should be fine.

I have had the dreaded 6A00 error on the MP500 printer which has been an excellent printer for the last 2 years. I found the problem is the purge unit as described above. My solution was:

1) Turn printer off
2) Slide printer head far to left
3) Get torch, cotton buds, window cleaner, plastic gloves and tweezers
4) I found several issues mainly to do with lots of ink clogging things up so do the following:
- Dampen cotton buds with cleaner and gently!! wipe sides, back and front of rectangular purge unit - it has a sliding mechanism and this gets jammed if clogged with ink
- Do this repeatedly and remove excess ink and fluff
- There is also a sponge like rectangular hard plastic piece about 1x1.5cm and 2mm thick - clean this and place back in place longest edge is left and right of printer (I thought at first it was a foreign object but having read excellent advice here it is obviously an important sponge for removing excess ink)
- This unit is housed in a position just below the ink units and was jammed in an upper position - caused by excess ink - after cleaning the sponge carefully replace with tweezers - be patient and gentle
5) Lower printer cover and turn back on

This worked for me after several tries - be patient and don't get angry - I have now had this error several times and have got used to fixing myself.

Brain,... First congratulations on fixing your printer. Too many people just give up and take it to the dump. Also, thanks for posting all the things you did to fix your printer. This has worked for MANY people. Someday you are going to have to take this printer apart and get down to the bottom of the purge unit and clean all the excess ink up. Sooner or later you will get the "Waste Ink Pads" are full and this is where the majority of the ink goes each time the printer wants to clean any of the printhead nozzles.

If you want to know more about how to Repair Your printer or to clean adn/or replace the waste ink pads, just click on my USER ID and send me an email with a short description about what kind of problem you're having with you printer, model #, etc.

I will send you a document that explains much more about my Repair Manuals and how to get one.

Anonymous,... I've very glad your were able to fix your problem using my suggestions. I would appreciate your assistance in helping other since there are so many suggestions posted in this thread, others don't really know exactly what you did to fix the problem. So it would really help if you would post one more time and say in words exactly how you fixed your error on your MP800. By the way, you really need to take good care of that printer since Canon has begun to degrade many of their new printers to compete with the HP "Throw-away" program. It is sad,.. but it is true.

This forum is suppose to be about helping people fix their own printers. No matter what the problem has been if I can provide information that can help someone with there printer I have done so. The evidence of this is the 100's of people that have sent me "Thank You Notes", similar to the one above. On those occasions where the problem becomes so difficult it can not be solved by simple posts on this web site, I have instructed people to contact me if they want more help.

I have been reading all of the posts about the 6A00 error I have. I can not manually move the carriage. It is in the parked position and does not move other than up and down when the printer is turned on. The question was already asked but I did not see any answers.
by COPA on Dec 31, 2009 at 10:50am Add comment
Copa,... Your situation is just a little different. The error can occur in many different ways. Sometimes there is a jam when the carriage is away from the park position and the purge unit gets stuck half way through a cycle. When the carriage returns to the park position it jams into the extended wiper blades.

A second type of error occurs while the carriage is still in the park position and something jams or breaks in the purge unit cycle. In this case the "Locking Lever" remains in the LOCK position and there is nothing your can do to move the printhead. It is locked in position. The only solution is to disassemble the printer and get at the purge unit manual gear and rotate them until the locking lever is dropped.

by Anonymous on Jan 2, 2010 at 8:03pm Add comment
Baffled,... Well you need X-ray vision to see it since it is almost at the bottom of the printer. It is physically inside the top cover all the way to the right side and this is where the Carriage unit and the printhead is parked & Locked when the printer is not busy. Because you signed this as "Anonymous", I'm not sure whom I'm responding to. Did you get the email I sent back with the instruction on how to attempt to clear the 6A00 error????

If not, then you are someone else, and you need to send me an email by clicking on my name and telling me the kind of printer you have and what errors you are getting and what you did that caused the problem.

Tavivi,... The 5110 error is the Carriage unit and it is hitting some kind of obstruction inside that is preventing it from moving up to check the height. This could be caused by any of the ink carts out of position and hitting the inside of the top cover. Or it could be that your refilling your own ink cart and have used "Screws to seal the fill holes. These screws are too tall and the carriage plus the screws hit the inside of the top cover when it is doing the lift test.

First turn the power off. Then opent the top cover. Examine every part of the insides has you power the unit on. Use a flashlight to see the details. You could have dropped something inside like a paper clip or hair pin, or whatever, which is preventing FREE motion.

You need to post more information.

My 'P1 MP830 is working well.

Now I'm trying to reset the waste ink counter to zero percent...
by risck on Jan 12, 2010 at 2:50am Add comment
risck,... In the Repair Manual CD I sent you the instructions are listed in the MP830 Canon Service Manual on page 1-43 starting with "Service Mode procedures". Once you are in Service Mode, just press the "Stop/Reset" button 4 times. Then wait a couple of seconds. Now press the ON/OFF button once and wait another few seconds, and the press the On/OFF button one more time. This will have reset the waste ink counter to ZERO.

Before you exit the Service Mode, make sure you have a piece of paper in the feeder and then press the stop/Reset button 1 time and then press the ON/OFF button once and you will print the Service test print. The top line of this print should have a "D=0.00" value which is telling you that the waste ink counter is now "ZERO". If you were not successful doing this then you did something wrong. Go back and re-read the instructions for getting into SERVICE MODE very carefully. If you don't do it right it won't work.

Hi trigger,
thank you for the additional informations. In the Canon Manual there is not mentioned, how often the On/Off button has to be pressed. All worked fine.
I would appreciate information how to get your CD, maybe by eBay if you didn't receive my emails (2).
There is another printer MP830 in my hands with problems on extra paper feed and not printing. I posted a new thread , since the thread 'MP730 paper extra feeds' is somewhat outdated and this is concerning with error 6A00.
Please help.
Klaus - risck
Hi trigger,
can you help with my issue of sheet feeder alignment in MP830?
I had the sheet feeder removed but did not disassemble it. I tried to realign it as it seemed to me it had to be aligned. But after all the printer started with error [6B00] 'Paper feed position error'.
The next idea is to look at the other MP830's feeder, how to align, unless I get help from here.
- risck
I just had that error message occur on my iP5200R. All I did to fix it was remove all the ink cartridges from the the tray, lifted the arm on the left of the tray and removed the back panel. I then used compressed air to clean the connectors. When I put it back together, everything was fine and have received no further error messages. It is now printing normally again.

Nebojsa,... There are two kinds of blinking lights. If it alternates between Orange and then Green and orange,.. that is alternate blinking "Service Call error condition. If it Blinks Orange-Orange-Ornage----and finally a long green, then repeats that is an "Operator Error" condition code.

For the Service call error,.. this means there is a problem with the VH or HIgh voltage driver to the printhead. Either the printhead is bad or the power unit is bad.

For the Operator error condition, this is just an error code telling you that you can not print data in DuPLEX mode.

So which is it???

trigger1937, thanks for reply. it is alternate blinking, orange then green, orange then green, 10 times, then solid green couple of seconds and again orange then green, orange then green... my friend have the same printer so i try his power unit in my printer and there is no change, the same alternate blinking is happened. do you think i should try his printhead, or somethin else? thanks - Anonymous
Mebojsa,... As I had said, if yours is the Alternate blinking this is a Service Call error and if your power supply is ok then your printhead is probably damaged.

Remove the head and clean it in the sink to get all the water off. Then use a magnification glass to examine the nozzles on the bottom. Look VERY CLOSE as you are trying to find something that looks like BURNT METAL OR A SHORT AT ONE OR MORE OF EACH TINY NOZZLE. If you seen any blemish in any nozzle the head is damaged and don't ever put it back in the printer again. It has a short and could burn out the logic card.

DO NOT PUT THE HEAD IN YOU FRIENDS PRINTER AS IT MAY DAMAGE HIS PRINTER. Your only option is to try a new printhead and if that does not work then your logic card is also damaged.

All of this is a direct result of continuing to print after one or more of your ink carts went dry. If the printhead is empty of ink and you try and print, the VERY HIGH TEMPERATURES CREATED AT EACH NOZZLE TO CREATE AN INK BUBBLE AND EJECT IT WILL CONTINUE TO OVER HEAT THAT NOZZLE UNTIL IT FINALLY BURNS IT OUT AND CREATES A SHORT.

ok, i will try to clean printhead and see if that helps. but, i was thinking, even if the printhead is damaged, is there should be some movements, from the paper motor or something, no matter of the printhead condition? i was thinking that the logic board is damaged too, or the eeprom is cleared due electric shock or something... but, if i try to replace logic board from friends printer, if printhead is damaged, it will destroy his logic board too.. i will try to wash and clean printhead first and see what will happen. thanks

Anonymous,... I don't know who you are or what your printer is, so how could I give you any help.

For most printers the 6800 error code is the result of a failed communications from the logic card to the eeprom on the back of the printhead. I don't know what you did but there is an electrical or mechanical problem with your head.

If you want some help you need to provide ALL the information, and login and give yourself a name.

I have the MP830. I got the 5C10 error, but not on the printer’s screen. It appeared on my computer screen. The only indication of a problem on the printer itself is the alarm light flashing. I tried the 6A00 fix, wiggling the purge stuff around, and have tried unplugging it, etc.

When I first turn the machine on, it makes start-up sounds for about 30 seconds (the screen just says Canon during this phase). Then it's quiet for about 30 seconds. Then it makes a louder series of warm-up sounds for about 15 seconds. Then the screen goes to its normal status mode. It's after this that it makes one more series of sounds - like something rolling or revolving - that the alarm light comes on. I can't "see" anything wrong with it. The cartridge carrier moves and lights as it should. There isn’t anything jammed in it. And apparently no one is familiar with the "5C10" code I get when I try to print from my PC.

I have read most of this thread and my MP830 is failing in a similar 6A00 manner and I guess I need the cd repair info since I can't even tell if my purge parts are all there. I see one rectangular hard sponge like area, but not a second one. My ink cartridge unit will freely manually move with or without power and is otherwise immoble. I mopped up some ink and cleaned off the now clear plastic wipers. I can push the pad area down but it comes back up and is just high enough to prevent the wiper thing from coming all the away forward (assuming it is supposed to SINCE NO ONE HERE has indicated that it should). The partially exposed white gear to the right of the pad will not move manually more than a couple of teeth worth.

The unit failed after normal use within 24 hours. On my first touch with a q tip, I picked up what appeared to be a 1/8" thin light piece of grey sponge longer than an inch right next to the pad. I tried to drop it back into the little rubber like trey next to the pad (where I now believe nothing is supposed to go) but I think it actually dropped down to the left of the rubber trey (where paper moves I think). It didn't appear to have any weight. I suppose this could cause additional problems and perhaps its previous looseness started things, but it aappeard so soft that I would have thought it would have been knocked out of the way.

Hi Chaso45,
you can only move the cartridge unit, if it will not be parked correctly over the sponges at the right side.
The two sponges prevent the printhead from drying. So they have to be in place.
I think you can only test the purge unit (by cycling the white gear clockwise) if the top of the printer and the mainboard have been removed.
I experienced a jam in the tube pump. Realligning and carefully reassembling solved the problem.
Good luck,

As you are there klaus, or someone else; can you tell me what the second pad looks like and the relation of the two pads. Also, can either of these pads be lifted up and be removed (and easily replaced afterwards). That might help finding junk below. and no dI haven't removed anything.
by chas045 on Feb 19, 2010 at 8:23am Add comment
the pads have the dimensions:
7 x 20 mm
15 x 20 mm.
Yes you can lift the pads (and rinse with water) and the housing of them is flexible. They are somewhat hard plastic and porous. Purging does not work without them. Beneath the purge unit (and the whole width of the paper feed) there are the felt pads, which collect the drained ink. There is no deeper hole in which your pad might have fallen.

To all of those Anonymous people that have has questions and/or posted "Good success" to this thread, I urge you to explain in more detail what you did to fix your printer. Yes we have provided all kinds of different things to try,... but it will help many other people if you would post "Exactly what you did" and what results you got".

Sometimes people try 2 or 3 suggestions at once and when they turn the printer back on they are just happy they got it to work. They don't know which one was the actual fix. The problem with this is that it does not help the next person and in fact,..when it happens again on your own machine you may not be able to fix it again.

Some of the things people try can damage the printer. If you want your printer to last a long time then you should want to learn how to take proper care of it.

Some people have been removing the small suction pads where the printhead rests and cleaning them. I DO NOT SUGGEST DOING THIS since they are very difficult to get at and if removed are extremely difficult to put back. If you drop one anywhere inside then your only choice is to take the printer apart. It will not work with either pad out of place. Also, once the pads have come loose, and ink begins to accumulate on them, they will have a tendancy to stick to the bottom of the printhead once is sets for several days. This will create an automatic JAM.

I apologise up front for the length of this post, but there is no other way I know to provide this information. I hope it will help dozens of people understand what is going on.

What is the famous 6A00 error in most Canon All in One printers?

Many people really don’t understand how the insides of a Canon printer work and have no clue what is going on when the get the famous “6A00” error. This note will try to explain a little more about these printers and what is going on inside. Unfortunately most of the websites do not have any ability to include a photo of the things I’m going to describe, which would really simplify the explanation. However, since they don’t I’m limited to verbal description and this is why this note is so long. For all kinds of printer problems, many people have ask me to just, “tell me on this web site what I have to do to fix my problem”, as if I were right with them and could see the problem. All of these explanations take dozens of pages and many high resolution digital images just to explain the problem. That is why I can’t post this information on these web sites. It is just too much. If any of you really want to see a picture of what I’m talking about, you can send me an email and I will send back the pictures.

The purge unit is one of the most important components of the printer. It is the unit that not only “primes” or sucks the initial ink into the printhead, but it is the unit that can “Cleans” a printhead when it get clogged up with old ink. If this unit is not working correctly, your printer will die an early death.

The purge unit is made up of many different parts and is one of the most complex pieces of hardware inside the printer. It consists of 8 major components. 1. The suction pads for both black ink and color ink. 2. The wiper unit which has clear plastic blades to wipe the excess ink off of the bottom of the printhead, and a front wiper bar that is used to wipe the same ink off of the wiper blades. 3. The drive gear which is used to push the wiper blades forward and clean the bottom of the heads. 4. The vacuum pump and control valves and suction tubes that are connected to the bottom of the suction pads. 5. The internal cam that is tied to the drive gear and the associated photocell/led sensor pair. 6. Logic control card and the integrated software that controls all of the operations. 7. The main drive motor. 8. A plastic Locking tab that locks the printhead in the home position.

Here is a “Simplified” brief description of a full purge cycle. Everything is at rest and the printhead is parked at home and the LOCKING tab is in the up position holding the printhead from moving. This is also the position of power off. The drive motor starts the process by turning the main purge gear and lowering the locking tab and at the same time lowering the suction pads away from the bottom of the printhead. Then the logic card moves the printhead away from the park position and the drive gear moves the wiper blades forward to clean an excess ink off of the blades on the front bar, which kind of looks like a hitching post. As the wiper blades move forward under the post, they are wiped clean. At this point the blades are supposed to snap back to the read by a spring since they are not driven back by the gear. The main gear continues on the cycle and returns everything to home position. After all of this initial cycle is over, the logic card moves the head back to the home position and locks the tab. A full cleaning cycle is about 6 times as complex as the above description which involves the vacuum motor cycling several revolution to vacuum suck ink out of the ink carts, down through the printhead, down through the control values, and finally down to the waste ink pads in the bottom of the machine. It does this in two full cycles since it only does the black first and then must repeat the same process and close the values that will suck only the colored ink. Once the cleaning cycle is done and all the ink has been dumped into the waste pads, the bottom of the head must be cleaned again so the basic wiper blade cycle described above is repeated one more time.

Now you know what all that crazy noise is when you first turn on you printer or when you want to print and it won’t happen for several minutes.

When the clear plastic wiper blades get extremely clogged up with sticky ink, they have a tendency to stick in the extended position.

Here is how it happens. The head is in the park position. The back wiper blades are gummed up with ink. The cleaning cycle with move the wiper forward and wipe all excess ink off the bottom of the printhead. As the wiper moves even farther forward it hits the final wiper BAR whose job it is to clean that same ink off of the wiper blades. Then the wiper blades are returned to the back position by a long spring. The problem is that when the ink gets so globbed up and sticky, the wiper blades will stick to the front bar since the spring is no longer strong enough to return it to the back position. This will immediately cause a jam because the "Dump" logic card does not know the blades are stuck. It tries to move the printhead and print something or just finish the cycle of testing but the head jams into the wiper blades and now we have a real error condition.

Put on a rubber glove and get a paper towel wet with very hot water and blot all of the parts that you can reach. You can do this by opening the cover and when the printhead comes to the center just pull out the power cord. Once that is done you can move the head to the far left and gain more access to the purge area. Use a flashlight and as many wet paper towels as necessary to clean off everything you can see of the sticky ink. The real problem with this is that you really can't get at all of the things you need to since the top cover is in the way. What ever you do, be careful since you don't want to dislodge or damage anything.

Trigger, you said you would get me some info when you returned from vacation. Since my heads have not been parked for 18 days(and I suppose not been active in any way) have they likely been dried out perminantly. So: while I would appreciate your advice, is it too late?
If not too late the info again: 6A00 after at most 1 day of inactivity. Head not parked. Pad holders up so wipers can not move over them but are free behind them. Longer pad is missing. Removed printhead, can't see it under print head. repeat of post on 2/18
On my first touch with a q tip, I picked up what appeared to be a 1/8" thin light piece of grey sponge longer than an inch right next to the pad. I tried to drop it back into the little rubber like trey next to the pad (**Canon said should be empty, but where the pad IS supposed to be**) but I think it actually dropped down to the left of the rubber trey (where paper moves I think).

Chas045,... from your description I think you have no other choice except to take the printer apart and dig out those ink pads, clean them and put them back in place. At the same time you will be able to clean the underside of the purge unit and all of the exit tubes of dried up ink. Finally you will be able to get at the bottom waste ink pads and remove them, clean them, and restore the printer to near new condition.

If you click on my USER id and send me an email I send you back a couple of pictures of what your purge unit should look like along with other information.

Hi!! I had the error code 6A00 on my printer a few month ago.I opened up the cover of the printer,i got to the ink and i cleaned it for over an hour and then i turned on the printer and it worked. Now i have the same problem but i can't fix it because i can't get to ink.

Simon,... You can't get to the ink because the printhead will no longer move to the center. The problem here is that the printhead has "Jammed" into the purge unit. I suspect the purge unit wiper blades are stuck in the extended position because of all the excessive stick dried up ink in the purge area.

Here is something you can try. Turn the power on and open the cover. If you ever see the printhead move even a small amount, pull out the power cord immediatley. Once the power is off you should be able to move the printhead to the left and get it out of the way. Now you have better access to the purge area where the jammed may have occured. Use a hot wet paper towel to clean anything you can get at but the ink pads and the wiper blades. Press the pads down just a little to make sure they are not locked. Remove the ink carts and the printhead and clean the head.

If you were not able to move the head at the begining, then the head is either locked in the home position or jammed so tight that it will not move. Try turning the power on and off and see if you can add just a little more force to the carriage by pulling it a tiny bit or pushing it a bit. If you get it to free pull the power cord out and proceed to clean as described above.

If none of this helps, then click on mu USER ID and send me an email. I will respond.

error code 6A00 appears on my canon pixma mp 830. I can not even try to fix it because I can not move the ink.

I have an MP600 but read this thread and was at first doubtful. however, reading how this error code was related to a paper jam, I turned off my printer, moved the printer head to the way left, stuck my hand in and fished around to the right and found a crumpled 1 inch x 1 inch torn piece of paper. I removed it, turned it off and back on and presto, the 6A00 code was gone and my printer was fixed.

rania,... The problem you have is a jammed printhead & Purge unit. It can be caused by several malfunctions but it all comes down to some jam in purge unit area.

If the purge unit can not complete a full cycle then it can not lower the Locking tab that will allow the printhead to move away from the home position.

You can make an attempt to free the printhead by doing the following;

1. With the power off, open the top cover.
2. Turn the power on and as the unit attempts to perform the initial test cycle, gently pull on the carriage assembly to see if it will move to the left. If you get no response. Turn the power off.
3. Now, turn the power on and gentley push on the carriage assembly to the right in an attempt to take the pressure of the of carriage and free the jam.

If neither of these work, then you are left with no other choice than to take the printer apart and get at the locking mechanism and free the carriage so it can move away fromt he purge unit and help you to locate the probable jam in the purge unit.

To get more information about this just click on my USER ID and send me an email.

I have an MP830 that prints OK but was given to me by someone who replaced it because a 12 inch long foam sponge came loose. Best description I can think of is that it looks like a city skyline and is varies in width from 1/4 inch to 1/2 inch at ends. I assume it is to soak up excess ink from paper as it passes through. Does anyone here know where this piece goes and if it is possible to reinsert it without disassembling the printer?

BTW, it's not the ink sponge that many are discussing here to fix the A600 problem

Thanks - dsteinschneider

Anonymous,... To everyone who watches this forum,... you can never be supprised at what you may find in your printer. From other people that I have helped, they have found everything from paper clips, to needles, to their Cat's favorite toy. I also have a picture of a printer that is jammed and there is a "MOUSE" stuck in the rear paper path. That was some kind of jam.

So I am at work and have tirelessly read through this forum with no luck.

1. I have an error: "Paper output slot".. "The paper is jammed. Clear the paper and press OK.

1 1/2. I opened every nook and cranny. Every door that will open and inspected every nook I could if I THOUGHT there might be papoer there. I was just told that a paper jam DID start this error off.

1 3/4.- I know about printers. Im not expert but VERY mechanically inclined.

2. So I moved the whole ink unit/basket to left and to the right, no luck. Did it a few times. Turned off and on the printer. No luck.

3. I got a paper towel. I think I found the purge unit. Its on the right side, top. There are some clear plastic (I will call them) window looking parts that had ink on them. I took a hot paper towel and cleaned EVERYTHING I could see.

Now I have fingers full of ink and 3 dirty paper towels for my troubble.

4. I was just told that a paper jam DID start this.

So If anyone has any ideas about where the hell the "paper output slot" is I would be much obliged :)

Any thoughts???????

JuhGail,.. First confirm that you have an MP800. While this is the subject of this thread that does not mean your really have one. Second,.. is there an error code to go with the words?

There are two locations that can create this error. First is the paper feed sensor which located at the back. If you ever had a jam and pulled the paper backwards, then you could have damaged the paper sensor and this will create the error.

The 2nd sensor is for the front door of the printer. This is not visible as it is inside and below the right front bottom corner of the printer. This error can be cleared and reset but ifthe switch is damaged or broken, the error will come right back.

OK Mam!...Just the facts please.

1. What kind of printer?
2. What is the error code?
3. Did your ever pull the paper backwards?
4. Will the error reset and go away once you press the "Stop/Reset" button.
5. Are there any other symptom or problems?

RJ567,...I got your email and I have already sent to you the information you requested. I would remind other people that the Canon Multifunctional printers are very complex units and are very difficult to take apart without damaging something if you don't have detailed instructions and pictures to show you the step by step process. Even more important is you have to know how to test it once you get it apart, and finally you have to know how to put it all back together.

These are great printers and if they are taken care of will last a very long time. The point is you have to learn how to take care of them.

dsteinschneider,.... There is only one sponge material in that printer that can match that description. It is the material that sets directly under the carriage (printhead) path that runs from side to side of the printer. It is there to collect any accidential drops of ink that may spill as the head moves back and forth. It is gray a is not a very dense sponge.

I have another similar printer disassebled upstairs and I will look at it and offer my opinion.

After checking my machine, I do not believe that you could get it back in place because with the top cover on you have very limited access to that area. Since it is not where is should be you will find an empty slot about 1/4" to 3/8" wide that runs the width of the machine. The plastic cover for that area looks more like a railroad track that anything else. You would have to use some twizzers to force the sponge back into place. The difficult part would be to get the spong strip back under the carriage assmebly without tearing it apart. But if it were me
I would cut it in the middle, and move the carriage asside and install the left half, then move the carriage over to the left and install the right half. To do all of this, Open the top cover and wait till the carriage comes to the center, then pull out the power cord. Now you can move the carriage by hand.

If you decide you don't want to try this and need to take the printer apart to really get at this area, just click on my USER ID and send me an email. Good luck.

There appears to be three common problems that causes the Error 6A00, which is related to a paper jam error.
1) If its a new printer or even an older one, there are two sponges that collect ink and two plastic wipers located in purge unit may be loose or missing. Check to see if its it there. If not, it may actually be stuck somewhere.
2) There may some paper stuck somewhere around the printhead and or the purge unit.
3) There is a build up of gooey ink on the purge unit.

Anonymous,... You need to provide more information. If you open the cover will the carriage move to the center? Are you getting any error message on the small display?

Pull out the power cord and wait 3 minutes then put it back and turn on the printer and see if you get the same error condition.

You probably have a jam in the purge area but you need to get the carriage over to the left to access the purge unit. If your carriage will not move, then you will probably have to take the printer apart and find the jam and fix it that way. Send me an email and I will send you more infomration on how to do that.

Thanks for you very valuable response on what the foam piece (sponge) is for and your idea on how to put it back without disassembling the printer. I was able to get it back in place without cutting it by opening the cover, unplugging the printer, then I pushed the piece back in to three quarters of the "track" and then just moved the printhead to the other side and finished pushing the material into place.

Someone please help. I have the error code 6aoo on my canon mp830. I have been trying to fix it using the posts but I really don't know what im looking at. It almost seems like the printer cartridges start to load up but then get stuck and don't come out from the right. I am able to pull them out when the printer is off but I am not sure if I am pulling and pressing on the right things. Any advice would be appreciated. Thanks!!

trackpet,... Your lucky if you are able to move the carriage unit when the power is off. This indicates that you really don't have a serious jam, but most likly just portions of the purge unit are stuck out of position.

With the power on, open the top cover and when you see the carriage move just a little way away from the park position, pull out the power cord. Now you should be able to move the entire carriage with very little force to the left of center. This will provide you more room to get at the top components of the purge unit.

If you have some vinyl gloves put them on and wet some paper towels. Use a flash light to examine the parking area for the Printhead. You are looking for a wiper blade unit that may be stuck in the extended (forward) position. It is normally spring loaded and should spring back to the home position, but after a lot of printing the wiper blades get gummed up with partially dried pigment black ink and become very sticky. They can get stuck in the fully extended position. Wipe them as clean as you can with the wet towels and make sure they are free to travel forward and back. It won't hurt them to slide them forward some and let them spring back. Clean any ink you can reach around the top of the purge unit.

Press down on both the ink pads at least 1/4" to make sure they are not jammed. Clean as much ink as you can off of the parking pads by saturating them with warm water. It is best you use a syringe if you have one,...this way water won't get all over everything else.

Let me know the results.

boydkelly,... I'm affraid you did break off a piece of the wiper blades that wipe the excess ink off of the bottom of the printhead. There are infact two blades so you have broken one. I don't think this is your problem though since you had the 6A00 error before you started cleaning.

If the head still comes to the center when you open the top cover that is at least some good news. This means you don't have the "HARD JAM" problem. However, there is still something somewhere in the purge unit or in the Carriage path that is the cause of the 6a00 error.

Open the cover and when the head moves to the center pull out the power cord. Now the head can be moved to the left by hand. Use a flash light to examing the entire path of the carriage to see if you can find any obstruction such as a paper clip, staple, piece of paper or string, or anything that should not be there. Move the carriage by hand the entire width to see if you fell any bumps or obstructions.

Examine the 1/4" wide timing strip that runs through the back of the carriage asm. Sometimes ink splatters onto this timing stripe and creates a bad timing signal such that the logic card thinks the carriage is hitting something. You have to be very careful cleaning that strip since you can only wipe it from right to left with a tissue wet with water.

If all of this does not help your problem it is probably down deep inside the purge unit and as such you are going to have to take the printer apart to get at the lower part of the purge unit and examine it for obstructions. If this is the case, just click on my user id and send me an email and I will respond

mrfredmister,... I would not get too excited if I were you. With that very little effort you had some success but without real cleaning your problem will be back and you probably won't be so lucky next time. At least you should take out all the ink carts, take out the printhead and clean it, and then use wet paper towels to clean as much of the ink you can get at inside the parking station or purge unit. Be careful as you do this as you don't want to damage anything. Saturate the parking ink pads and blot them until you can get most of the ink out. Someplace on this web site I have posted instructions on how to clean the printhead. Search for it.

I fixed error 6A00 on my MP530 by moving the print head to the left and pushing the small sponge assembly back down gently with a tool. You'll probably need a good flashlight to see the sponges if they're stuck in the 'up' position.

rjackal,... You did a good job. This type of error can really cause MAJOR problems if not taken care of quick,.. but you did. Now the real problem is that your error will come back since you did not clean up all the excess sticky ink that caused the jam in the first place. Use some hot wet paper towels to clean up as much exposed ink as you can reach,..and put on some vinyl gloves.

Today my MP830 started giving me the 6A00 error code. I've checked the paper paths and tried cleaning the print head etc. but still no joy. I notice that there is no illumination of the printer cartrdiges and the print head does not move at all before I get the error code. I'm guessing this may be terminal?

slicknick,... No this is a pretty standard error for any of the Canon MPxxx units. YOU ARE LUCKY, as your printhead actually MOVES. Most of the time the ink inside the purge area is so gummed up and sticky, the wiper blades that clean the bottom of the printhead, get STUCK "Extended" and as the printhead & Carriage try to go back to the home position, you have a servere train wreck. The Carriage jams into the extended blades causing such a jam that the carriage can no long move in any direction.

My MP830 is showing the dreaded 6A00 error.

I cleaned the wiper (two rows of clear plastic) with Qtips and lots of Windex.

I also removed, cleaned, and replaced the two sponges (one a 1/4" x 1-1/4" strip, and the other a 1/2" x 3/4"). Are these are the 'sponges'? They seem to be a hard and porous stuff.

One thing that happened when I removed the sponges to clean was: the tray that held the sponges came back up. This used be in a lowered position. Now it is in the 'up' position, and moves freely up and down, but does not go all the way down to the position I found it in.

When the sponge was in the 'down' position, the asm with the clear wiper strips could move forward and backwords freely.

I tried to push down the sponge tray down but does not stay down. Is this supposed to be in the 'up' positon? Looks like not - from a previous post.

My current status is:
On powering up, the carriage unit does not seem to move at all, but can be moved freely by hand.
I still get the horrible 6A00 error.
The carriage unit can be moved left to right and back freely.
The sponge tray is in the UP position and can be pressed down. but does not stay down.
The wiper blades are cleaned and will move forward and back free if the sponge tray is in DOWN position, but the tray won't stay there.

Any help with to fix my MP830 will be very much appreciated. Thanks in advance.

Hi joe1599, I am waiting for some details from trigger1937 that may help resolve the issue. it sounds like you have exactly the same symptoms as me. Trigger1937 had a problem sending me some attachments previously due to a mail size limitation with my ISP by the sound of it. I have sent details of a hotmail account which hopefully will not have the same limitations. I am just waiting for the info to arrive. When it does I can pass it on and hopefully we can resolve our problems.

One question though. Do you have any illumination of the print cartridges when you get this error code? Mine are completely dark.

Hi slicknick, my print cartridges do not illuminate either.

After reading this group of messages I am truely amazed at the different fixes everyone has come up with. But I have also noticed in time the problem returns. The real fix in 90\% of all cases would be to just simply replace the purge unit, yes they are available and if your so handy as to be able to get inside the unit, I'm sure trigger would also be happy to tell you all how to remove the entire print unit from the body of the printer and change the purge unit! If you do NOT find a bobby pin, barret, push pin, tack, chunk of wall board, candy, staples, paper clip, shardes of paper scraps, rubber bands, nylon ties, condoms, yes condoms, chunks of broken plastic from who knows where, teeth from a plastic comb, assortment of different breakfast cereals, and other such debris, chances are you should just ease your pain and replace the purge unit.
We do carry the parts and believe me, its the better permanent fix! Chances are you should probably replace the blotters too, its a rather large group of them but they all come in a kit. Then find out from Trigger how to reset the blotter counter and you good to go for a couple more years.
To prevent the problem from occuring in the future, never shut off the printer.

Yes, move print head to the left and look inside, with a flashlight. The purge unit on my MP830 os a white plastic unit. If you can get your fingers on it, gently move it back and forth not side to side.. It should move freely, then try using the printer. read some of the other posts about cleaning all the old thick ink off what you can reach inside.

I just had same error and resolved it by one of the following:
1. There was a buildup of black ink in the area where the print head comes to rest on the right side -- cleaned this up with a kleenex.
2. Oiled the round chrome rod the print heads travel on with "Singer sewing machine oil".
3. Fiddled with the CD-R Tray (who uses this???)

Powered it back on and it is now happy.

jdornski,...Good job and thanks for posting your success. I believe the fix was the cleaning of the sticky ink off of the purge unit, and I would not recommend "Sewing Machine Oil" since that is not what Canon puts on that shaft. The use white Lithium grease or Silicon grease.

As far as the CD Tray,...Many people use it,... I use mine almost every day. I make my own Photographic labels for every Repair manual CD that I send out. I use high quality "Printable" CD's and good quality photos and they come out excellent. When you got your printer the CD function was disabled since Canon has never paid the rolarity rights to Epson who owns it. However, it is very easy to enable the function again and to install the necessary software and reload the drivers. Once these simple things are done, you can print your own CD's, and DVD labels.

simple fix!

open the ink toner area as if you were going to change the ink (seems like we do this WAY too often!) and slide the toner all the way to the left. put your hand in on the right - along the "floor" and you will feel a sponge. Push it down gently.

you will get ink on your fingers but its worth it!

I have a Canon Pixma MP500. After replacing my yellow ink with a refill catridge the Error 6A00 came on. I followed all advise on this site. I moved anything that could move on the right side of the printer. When I moved a thin object (no idea what it was) and turned the printer off and on, the error was gone. Thank you everyone for your advise.

DLD,.... If your carriage will not come to the center or at least move away from the home position once you open the top cover, then you have the worst possible Purge & Carriage jam. This is typically cause when the wiper blades in the purge unit are so clogged up with stick ink that they get stuck under the front wiper blade when they are fully extended. A Spring is supposed to snap the blades back to their home position and make way for the carriage and printhead that are about to move back to the home position. Since the blades are stuck extended the carriage & the printhead "Crash" into the purge blades. This will totally stop any further rotation or movement of most parts inside the purge unit,.. and you will get the 6A00 error code.

You have to take the printer apart to get at the full jam can clear it. I have sent you and email with my address so just send me a response and I will provide more information.

Paper jam error on PIXMA MP600R.
I just had the nasty error 'paper jam' on this otherwise nice little unit. On starting up, the printer would do its checks and move the ink cartridges normally, but the screen would refuse to budge from the dreaded "paper jam error. Remove paper from paper output etc". No buttons on the console would do anything. I tried the fixes on this page, but to no avail. I'm sure I caused the error by trying to pull a sheet that had entered the top inlet at an oblique angle, and was making a crunching noise. I had pulled the sheet back out the top (completely intact) but the message already came up (note to self: do not do that again). What I noticed was that even in its 'I have a paper jam' mode, on being switched on from an off state, the printer takes a piece of paper through the mechanism from the top feeder and sends it all the way out, unprinted to the tray, before sulking again. I fixed my printer by sending a very heavy sheet of cardboard (A4 size) through from the top, after having turned the printer on from the off state. I held the thick sheet of card and at the appropriate time, gently persuaded the thick card into the printer, and the MP600R managed to push it through, grudgingly, as far as the output tray. Here, I got hold of the card again, and very gently pulled it through all the way at the same speed as the printer was trying to send it through. The screen came to life and said "processing' and now it works again. Don't know if I dislodged something that was in the way. The card I used was a smooth white card that came as the backing of an ordinary 80 sheet Ryman stationers pad. Hope this works for someone out there...although I guess no guarantees for home cures!

My MP830 recently gave the 6A00 error. None of the easy fixes worked so I obtained a "service manual" and pulled it apart. I found the problem was in the purge unit in the cylindrical part at the end nearest the front which looks like a motor but is a peristaltic air pump. The tubing which produces the colour side vacuum was pulled off its connection and the other end jammed in the cogs driving the pump. I was able to dismantle the purge unit and reassembleand it seems to be working Ok by itself. But when I reinstalled it in the printer I no longer see the 6A00 but the orange alarm flashes after It tries to print. I think the purge unit gear needs to be synchronized with the gears that drive it but the Canon manual gives no such info. If anybody has an answer I would be grateful.

noprinto,....What a very clever name,...First off, congratulations on getting the printer apart,..and the purge unit, and getting it all back together. The gears of the drive shaft and the purge unit will sync themselves. I hope you did not take the purge unit totally apart to get at the vacuum pump and the loose hose. You may have gotten the timing cam inside the purge unit at the wrong sync point. It is never mean to be taken apart.

However, now that you have it back together, you don't get the 6A00 error but some other error code. Since you have the manual you have the listing for all possible error codes, so which one is it???
by unknown on Sep 21, 2010 at 10:20pm Add comment
Thanks for replying. I'm happy but surprised to hear that there is no sync isssue with the gears. As for the purge unit, I did unscrew the two screws which hold the right side on. The problem was that a white plastic roller had been dislodged and I had to relocate it so that the tube could be relocated. The wole unit was not dismantled and I dont remember being aware of a timing cam??

When I turn the printer on it makes all the usual noises. Then when I ask it to copy, there is a repeated "click" noise which sounds like slipping cogs, about 2/3 of a second apart, and this happens about 5 times. Then the orange alarm and green copy lights falsh (12 times which is equivalent to the 6A00 ERROR) but the screen just indicates a copy in progress without stating a 6A00. The clicking noise is also heard on startup sometimes but not always, and does not stop the printer functioning at this point. Sometimes when I ask it to copy I get a 5100 error ("an error occurred un the carriage encoder signal).

Looks like I'll have to dismantle the whole thing again. I'm afraid these modern ribbon cables are quite delicate and wont tolerate too many plug/unplug cycles before they stop working.
Any other advice would be appreciated.

I am having a problem when printing photos. It prints black wispy lines over all my photos. I am using new ink cartridges with glossy Canon photo paper. I have printed tons of photos before this with no problems. I got it to print one page with no problems, but now it won't stop doing this - even though I have cleaned the print heads.

Please help.

Charlotte,...There is a sensor in the paper path that detects paper. This is done my a tiny plastic arm that is moved out of the path when paper touches it. Sometimes this arm gets stuck out of place, or is jammed up by bits of left over paper from a real jam.

I'm not familiar with the MX320, but it is probably just like all other Canon printers. Try giving the printer a little shake, or drop the rear of it from 3-4" off the table. Open the rear turn around if there is one and use a flashlight to examine the entire path searching for any bits of paper.

The only other option is to take the printer apart and get at the sensor to see what is wrong.

Bought a PIXMA MX860 a little over a year ago with my Mac. The 860 is slower than I'm used to but here's what is driving me crazy:

Error Code 5100 is now showing up so frequently, I can't get through even a 5 page document. I get the error code far more times than I get a document to print. Since my stuff is Wi-Fi, going back and forth to the printer to turn it off and on is a pain.

I called Canon and they said something must be jammed inside but how can that be since it does work some times? The Owner's Manual does not offer anything helpful.

My ink tanks (Canon) are full, my paper tray is full, the copies I do get are beautiful, and it still gives me the 5100 code all day long. I can't rely on this particular machine and I can't afford to buy another.

Is there some special paper (weight, brand) I should be using? Any other suggestions? I am not working so paying a lot to have it repaired is something I'm trying to avoid.

You folks are very smart. Anyone have any ideas?

Crystalball,... I'm sorry to hear of your problem and I can feel your frustration from end to end. The problem is that sometime in the past your machine did have a paper jam and someone did the wrong thing and pulled backwards on the paper while it was still in the process of jamming. The correct thing to do is to go ahead and just let the printer complete the jam, as they are designed to handle this. What they are not designed for is someone pulling backwards on the paper at the same time the printer is pushing forward with a real JAM. The paper tears and things get jammed in weird places.

The only 3 things you can do is to examine the top feeder area or the lower turn around area and try and find and remove any old tiny piece of paper that could cause the sensor to give a false error condition.

The 2nd thing is to try and free a temporary stuck paper sensor by lifting the rear of the printer about 3-4" and dropping it. Only do this once, since if it does not work, you have a much more serious problem.

The final solution is to take the printer apart down to through the top inside cover and now you can get at and examine the paper sensor and see why it is failing.

If you try all of my suggestions and nothing helps, then send me an email and we will proceed from that point.

I have been getting the same old error 6A00 and 12 oranges flashes with my ip4500. When I first looked for the purge unit as described, I wasn’t sure I was looking at the right thing because it scarcely moved at all. However, when I later revisited the inside of my printer, it moved easily. I moved it backwards and forwards several times and then finally pushed it back. I wish I hadn’t - I think I must have moved it too far. There was a click as I did it and I later found that the two sponges had popped up, so that the purge unit is now more immoveable than ever. I tried to push the sponges down but only succeeded in dislodging the smaller one, which has disappeared into the recesses of my printer.

Can anyone help, please, or have I just finished the thing off?

My MP530 has been making a 4 second-long chattering noise during the automatic cleaning cycle. I tried to open up the machine but couldn't get to the gearing to see if something was hanging up. I did cause the spring-loaded wiper to stick and cause a 6A00. After reading posts on this site I moved the carriage and eased the wiper back into place, problem fixed. I need to read up on how to clean that whole purge assembly, is it in the online manual (doubtful) or does your handbook have it trigger1937?
I still have the chattering though. I just did a deep clean and it happened but very slowly compared to usual. Thoughts?

Mongo,.. it sounds like you may have a slipping gear or some kind of interference down inside the purge unit. You will need to take the printer apart to see what is happening. The worst that could be wrong is that some part is broken in the purge unit and you will have to replace the purge unit. This is not a problem as Canon sells those parts at a reasonable price. I have sent you an email and when you respond I will send more information about my manuals.

Ok, I have read everything, and I still get the error message 6A00. When I turn the machine off, and then back on, it seems like it goes through it's start-up ok, but when the release activates that opens the front door, that is when I get the dredded 6A00 error. Does this help anyone with a solution???

bigsky,... The 6A00 error is a carriage jam with the purge unit. Open the top cover and see if the carriage will still come to the center. If it does then you just have a jam with the purge unit. Send me an email and I'll provide more data.

I was given a 830 which has the 6a00 error code showing on the LCD and 12 blinks of the error LED. I have read every line on this thread. I have put all the pertinent ones to use and have now torn the beast apart down to the bottom shell, electrics and printer deck, with the purging unit. After cleaning the unit up to the point it was safe to touch without gloved hands I rotated the protruding gear toward the rear and the wiper moved partway forward, the gear stopped. I reversed direction and have found that the gearing must ratchet since the wiper moved forward some more then stopped. Did this four times to get the wiper and pads back in position. I then cleaned some more. I plugged all the ribbons back in fired it up and everything moved, lit up and acted normal. Thought darn I'm good. Turned it off and back on and the purge gears jumped. I backed the gear up turned it back on and the pump worked, the cam worked,the slider worked, and the machine asked me to reset the paper to copy. And I thought darn I'm ......
The pump locked up again and I have now done the above three times.
There is a black plastic piece on the pump shaft w/tab that engages the large white plastic gear. It jams some times and not others. I can find nothing blocking this piece. Someone has written of rollers which I'd guess are inside that pump massaging the tubing.
I have not been able to intuit its removal, nor do I see anything in any manual, thats free, on how to do it. But I do love a challenge. And who knows I might win.
Trigger you said something about pump pictures. I'd like to see them and will be contacting you.

Well I've jumped in with both feet and figured out that the pump roller was not where it was supposed to be. Pulled the purge unit out, replaced the roller, reassembled the unit only to have it fail again. A piece of the roller retainer is missing.
As BAB said replacing the purge unit is the easy fix(and only fix for this unit).
If you clean up the gummy sticking parts and it still won't work, replace that unit. If it cost $30 and a couple hours work, thats good.
BAB and Trigger keep up the good work.

i think it may have something to do with the lubricant on the bar that the ink cartridge slides along. i think mine either dried up or got too cold cuz when i manually slid the cartridge back and forth it was not smooth. try re-lubricating the bar, wd-40 would probably do it.

Canon uses white lithium grease. DO NOT spray WD-40 on it, as there are solvents in it that will harm your parts.

I had the same problem with my mp 830.

I tried all the suggestions from you guys but it did not work.

After an half an hour of trying to fix it i had the great idea of smacking it to the table. I took it up and dropped/pushed it to the table medium hard.

And it worked. Stupid printer sensor, you just need to smack it :D

I've got the 6A00 error on my MP800R. I've tried all the suggestions here, but to no avail. My last attempt has been to disassemble the printer to get to the purge unit. I have the MP800 service manual and have managed to remove everything except the top grey housing directly covering the purge area.

The back of this housing is free, but I can't get the rest (front) of it off. Something is holding it in place, but I can't figure out what. Unfortunately the service manual does not give any instruction on how to remove this part of the printer to get to the purge unit. For some reason it skips that part.

Any help would be greatly appreciated.

A 830 has four screws holding it. One at each outside corner in the rear and one in each depression on either side of the paper out slot in the front. You have removed the corner covers already? Hope this helps, good luck. - unknown
I recently puechased a Canon mp830 at a college surplus store. When we turned the unit on it the error message 6A00 came on. We tried messing with the purge unit and that didn't help. We did notice that when we opened the unit when we turned it on the carriage that holds the ink didn't move. so not sure what to try next, maybe cleaning with windex. This is the first that we have owned a unit like. Hoping we can fix it. any other ideas would be appreciated.

My MP610 caught the dreaded 6A00 disease. The ink carriage was not parked on the right, but could move freely back and forth. I found a sponge pad on the right, underneath where the carriage parks. When i touched the sponge pad it clicked and dropped down a couple of milimeters. Printer worked OK after that. It's difficult to see in there, and i don't know how to remove the right panel to see more clearly, but i'm happy for now.

After searching canon web site and the internet, I used google to ask my question and I found these posts. Yours had the magic step. I had found the little piece of paper jam and moved the carriage back and forth, but it was the little sponge pad on the right that I touched and it went down as you said. Printer seems to be working now. Will cross my fingers. Thank you for posting your ideas!!!! I gave a MP810. - unknown
My MP830 developed the 6A00 error also. I have tried cleaning the unit as described in other posts but to no avail. In the end, I opted to buy a replacement purge unit from Beck's CRS Inc. in Illinois.

I also emailed trigger1937 about one month ago asking for details of the service/repair manuals for the mp830 that he has mentioned but have heard nothing since then. I am about to try and dismantle the thing and see how far I get.

Note for UK readers: My replacement unit cost $34.99 plus $30.65 postage (that's £22.65 plus £19.84). Customs decided to add another £7.21 VAT as the part value was over £18. Royal Mail then added a further £8 handling fee! It took a month from ordering to arrival.

Several years ago I had the paper error. I did find a jammed sheet and pulled it out carefully. However, a very small piece of paper remained in there and that was enough to prevent printing. I took the entire printer apart and never was able to reach the location that had the quarter sized paper. I shook the whole printer and eventually the paper moved to a location where I was able to reach it with tweezers. Why would they ever make a printer that has no way to get to the entire paper path??????

Now it said wrong print head. But before I could solve that problem it won't turn on. Screen lights up for about a second then black. Does anyone have any idea why now it just won't turn on to even give me the error message????

Ack! There was a paper jam when printing duplex. I removed the jammed paper, but the machine claims there is a jam still. I cannot see any jammed items. The printer cartridges no longer light up and the cartridge track does not move to the accessible position when I open the front compartment. I have manually moved it back and forth several times. The printer will not turn off. I have unplugged the power to attempt to turn it off and reset whateverneeds resetting, but that has not worked. I'm desperate for advice!

EZ,... You are lucky you can move the carriage. Most of the 6A00 errors are caused by a carriage asm jammed tight into the purge unit and they can't be moved. Since you still have the error, something inside the purge unit, or even under the carriage is creating the error. Move the carriage out of the way and examine the tray underneath the carriage for any object like a paper clip, staple, push pin, hair pin, etc. Anything that delays the movement of the carriage or the purge unit during the cycle can create the error.

With the carriage over to the left, use a flash light and examine the purge unit. The wiper blades should not be extended or stuck to the front cleaner blade. When you power the unit on do you hear any strange noise from the purge unit. Do you hear it moving at all. Send me an email and I'll send you some more things to test.
by unknown on Jan 6, 2011 at 9:42pm Add comment
I've looked for those things but don't see anything. I'll check again. The design of the unit makes it extremely hard to see inside it and peer underneath. I've read this about the wiper blades but don't know what they are, where they are or what I should be looking for. I don't hear any strange noise (like the crunch some people have mentioned) when I power it on although I may have heard that crunch the first time this error showed. The ink carriage which used to move when it powered up, no longer seems to do so. Other than that, it just sounds like it is trying to move things or do things that it cannot do but there are some parts that move during the warm-up. - EZ
EZ,... From what you have described the purge unit is jammed. Once this happens the printer will no longer attempt the normal power on diagnostics. Yes the purge unit is hard to find. If you open the top cover and with the power off, move the carriage to the far left side. Use a flash light to look under the top cover into the far right side. You will see to ink pads, one long and one square, that is where the printhead is parked. These pads keep air from drying out the ink on the bottom of the printhead. Click on my user ID above and send me an email. I will return a more indepth description of the purge unit and some pictures.

To Kim,..and anyone else watching this thread.... Never move the carriage of any Canon Printer until you "Turn the power OFF". Then it will move freely. If you try and move it with the power on you could "Strip" the teeth in the drive belt.

Kim,... It is really not a sponge. It is two small pads of material that rests under the printhead when it is parked in the far right. To locate these, just open the cover with the power off and you will see exactly where the printhead is parked. You can not move it now because the purge unit has placed the parking pads (ink pads) firm to the bottom of the printhead and raised the "LOCKING PIN". The pads keep the printhead ink from drying out and exposed to open air. The pads are also used to "Suck" ink out of the ink carts and down into the head. This is the function of the purge unit. This is how ink gets "Primed" or pulled into the printhead. The "Ink Pads" are porus and there is a suction pipe under the center of each ink pad. The vacuum suction pump in the purge unit "Sucks" the ink into the head and this also cleans the nozzles at the bottom of the head. The waste ink is then dumped into the bottom of the printer onto the "Waste ink pads"

Kim,,.. to get your printer working you probably freed up the purge unit because the wiper blades that clean the bottom of the printhead was stuck "Extended", and when you touch it, it released and slid back into position.

Let me add another wrinkle, for whatever it's worth. I finally called the local Canon service location. The man told me to try this: power off, move print head away from its parked location and remove the cartridges. He told me how to remove the print head this way: on the left of the print head is a lever that you pull up and it releases the print head. Take it out pulling toward you and lift out. It came out very easily.

Remembering that my problem is that it used to tell me I had the wrong print head, then after a while when I turned the printer on, I got 1 second of the blue screen, then blank and from then on nothing would happen until I unplugged for a few minutes, then plugged it in; the same would happen again.

He told me that if, when I remove the print head, close it up and power it on, if it did the same thing (i.e. 1 second blue screen then nothing) it means I have a short circuit in my print head and I need a new one, costing around $60.

Just to make sure all was OK, I cleaned all the contacts of the print head, replaced everything in there again, only to find it changed nothing.

I'm about to order a new print head and hopefully I'll have my printer back.
by Ron T on Jan 8, 2011 at 1:34pm Add comment
Ron T,... He is probably correct,...but there is one more test to do to make sure it is not something in the logic board. Remeber, the wires in the head are electrically connected to the logic board, and that is where all the decisions are made.

With the head and ink carts removed, and the carriage lever locked in place, plug the power back in and turn the printer on. It should go through all of its power on diagnostics and then come up with this error on the display,.."Please install the printhead",... or some words to that effect. If it does not do that you may have something else wrong.

Your lucky the local Canon Repair center even talked to you. Most of the time all they will say is bring it in and we will test it for $80/per call.

Also, if you really do need a new head, order it directly from Canon and you will get a new head with a warranty. Call the parts department at 1-866-481-2569,...give them your printer model number and tell them this will be a credit card order since you do not have an account with them.

trigger 1937:
Thanks for the heads up. I did the test you mentioned and I got the exact message you said: "Please install the printhead". Another confirmation that I need a new print head.

Likewise, I appreciate the recommendation that I get the new print head from Canon.

I am lucky the guy talked to me and I believe it's because it's not a large company. I called and got the answering machine, then he called back the next day, so I think it's a small operation, which is always better because you do tend to get better service. And when I called him I was so frustrated with the whole thing, I was willing to take it to him. - Ron T
Could you please send me some pictures showing how to get the purge unit unstuck? I'm unclear about which plastic piece is the purge unit. The carriage moves but does not light up.

Last year I had that paper jam message and I could not find any paper anywhere. I took the entire machine apart, could not get into it, but did finally find a quarter sized piece of paper which I was able to reach with tweezers. How one would get into that paper path is beyond me and I was very fortunate. - Ron T
Ron,...I think you were lucky. Durning the paper jam it is clear that you tried to pull the paper backwards as the printer was moving it forward,..and this tore the paper. This is one thing anyone should never do. Let the paper jam continue by itself, as the printer is designed to withstand a jam. What it is not designed to do is to tolerate someone pulling the paper backwards while it is trying to move it forward. Once the jam stops just turn the power off and then open the rear turn around door and fish out the paper. People have really screwed up the drive mechanism by pulling backwards.

I am ready to smash this machine with a sledgehammer! First, every time I try to send a fax, it starts saying "auto redial" and won't send the fax (the fax function worked fine at first, but now it does this every time, and everything I've tried to correct it has failed). Now, when I try to print something, I get a message saying "operator error" - it was working fine, but now this happens! I tried doing what it suggested - turning off the machine, then on - but now I get a message that it's a problem with the printer head!
And today I tried to scan something, and it won't do that either!
I think I'm going to throw this thing out the window! It would probably cost more to fix it than to just go out and get a new printer! I'm not buying another Canon, though!

Italiagina,... It doesn't sound as if you really want any help,..just some confimation that "Canon Printers are no good". Well you won't get that here,... In my opinion, and I have worked on and fixed 100's of them,..they are the best. I think you just got a case of the "Electronic bug infestation".

Pull out the power cord for a few minutes and let the internal error conditions reset. Now think calmly on what the status of the machine was when you got each one of those errors, and was there a logical or probably cause for any of them. Look around and see if there is something that is not in the right place or just out of place.

On this web site we only give help to those who really want it and ask in a nice way.

Many thanks to trigger1937 for creating his own repair manual. I have successfully replaced the purge unit on my MP830 and everything is working perfectly now. I also learned a lot about the internal workings of the printer and how I can keep it running for a number of years to come.

Well, all I can say now is that, if you tried what others have suggested, mainly to clean the print heads, and you still get the message WRONG PRINT HEAD, then believe that it's the print head that has gone bad. At least that's what worked for me.
It's easy to remove the print head; lift the lever on the left after moving the cartridge holder to the middle position, reach inside you can pull out the print head (remove the ink cartridges first).
I ordered a new print head form Canon for about $70 and all is well. If I had done that a few months ago, I would have saved myself a lot of stress about it.

Hi all. Would be very glad if some has some suggestions for me. I have the 6a00 error problem and tried all the suggestions here (no jams found, moving carriage left to right to left a few times,pressing the ink pads up and down, and moving the purge unit back and forth), but they didn't work for me.

I have since stripped down the printer so that I can get to the purge unit properly. That is the stage I'm at now. I've looked at the purge unit / wipers but can't see anything that is obviously out of place, or shouldn't be there. I can move the purge unit back and forth with no problem, however I would like to to know if the purge unit is supposed to go all the way back (when not in operation)? Also what should I try now that I have it open? Shall I attempt to clean the pads and the wipers?

Is there anything else I can do besides the above, because eventually I'll have to put it back together to see if it works, and if the error is still there I'll likely throw it away - such a waste of resources.

You could try removing the purge unit and cleaning it, I found it fairly easy to remove. Don't get any water in the purge unit motor though if you do and make sure it is properly dry before refitting it. A replacement purge unit is not that expensive (a lot cheaper than a new printer) and if you replace it and clean the waste ink pads too it should work like new. trigger1937 can supply additional instructions if you need them.

Actually I didn't pull the paper backward. I did however pull if forward to try and remove it since it was stuck in there. That's when a small piece broke off, about the size of 2 quarters, and there was no way it was coming out no matter what I tried. That's why I tried to disassemble the printer to get to it. I never did get it apart enough to reach the piece of paper. However one time when I moved the printer the paper moved into a place where I could reach it with a pair of tweezers.

A month ago I got a new print head and all was hunky dory. I've perhaps printed 15 or 20 pages only. I have a laser for most text printing.

Now the black (the PGI black, not the CLI color black) doesn't print right. I've done the clean head several times, and the deep clean a number of times, but it still doesn't give me correct printing.

Anyone got any suggestions on what to do?
by Ron T on Feb 28, 2011 at 7:47pm Add comment
Ron,.. There are dozens of reasons this could happen. What kind of ink carts are you using? Do you refill your own ink carts. Have you ever removed and clean the head. Where did you buy the new head and was it used or new? It could be failing because of the black section of the purge unit is clogged. To test this you will have to send me an email so I can send back the test. They have no feature on this web site to send attachments.

Click on my USER ID above and then add some detail words about your printer, model number, etc. and I will respond.

Thanks for any help.
by nealkat on Apr 2, 2011 at 9:46am Add comment
nealkat,....Just because the head and carriage move and the purge unit moves does not mean there is not problem. Pull the power cord once the head is at the center and then move the carriage by had and see if you find any point where there is any resistance. The timing sensor in the bottom of the purge unit could be covered in ink and sending the wrong signal. Also use a flash light and check the Timing strip that runs through the back of the carriage asm. If there are ink spots on this it can cause timing errors which is the main reason that you can get the 6A00 error. Have you attempted to clean the wiper blades on the pruge unit or to clean the ink pads? The printer will not do any other function until the 6A00 has been cleared.

The final solution will be once you totally disassemble the printer and manually cycle the purge unit by hand and examine the underside parts.

I went through this problem with the stuck ink carts last month and fixed the problem by pressing on the sponge. The error message came back and so, feeling like a pro, I pulled the plug, cleaned the wipers, blotted the sponge and tried to start it up. Now the sponge is missing. I found it deep in the recesses of the front right corner of printer very much stuck. What do you suggest trigger1937? Where can I buy a new little sponge? Or should I take the whole thing apart to release the old one? Thanks for your help.

Shirly,...I think you have found out that it is a waste of time to try and print a check. What happend is that it wrapped itself around the inside feed rollers so none of it is visible at the rear or front rollers,... or it could be compressed like an accordian between internal rollers. The sad news is that you will have to take the printer apart to get the paper out. If you want more information on how to do that, click on my USER ID and send me a note with the information and I will respond.

LoisL,... IF the ink pad is jammed so tight that you can get it out without destroying it, then you have to take the printer apart and get at the purge unit. You DO NOT WANT TO DESTROY THAT INK PAD as it is a critical part of the purge unit. They do not sell the pads separately because they only sell the full Purge Unit. Right now with the trouble in Japan, they may not have any in stock in the US. Send me a note.

Thank God for these posts!! I have so much work to do and got the 6A00 error, and at first thought it was hopeless. Following the suggestions, I used a flashlight and looked everywhere for paper or debris. None there. I wiped the sensors under the ink cartridges "home," and manually turned the output rollers - while the power is off. And ta-da! I am back in business, but will be ordering new laser printer shortly after this episode.

Hey guys! I been following this thread for about 2 weeks. I got a lot of great info that finally helped me to fix my problem. Let me tell you all what happen.

1. I got a Canon Pixma MX850 about 4-5 years ago.
2. For some reason when I switched the printer to print at lower quality something happen to it.
3. Next I got the dreaded 6A00 error.
4. I proceeded to follow all the ideas you all gave me. I looked for the little washers to the far right(the area where you slide the mechanism where the ink goes) of the machine. I saw that they had came loose for some reason.
5. I took the little washers (it looks kind of like 2 little sandpaper pieces, and when washed they turn white) out and clean it under the sink.
6. It was a messy job and I suggest you get some latex gloves so it will not get all over you.
7. After cleaning them I put them back and for some reason they just didn't look like they were going in right.
8. It was very hard to see what exactly I was doing because it such a tight place to work in.
9. I closed up everything and turned the printer back on and I still got the 6A00 error. I was fed up because that took a long time.
10. So, I bought a laser printer for 100 bucks after that.
11. Next night I couldn't sleep so I just started working on it again. However this time I took the whole thing apart, it was a task because it has screws all over the place. You just got to work on it and see how everything goes where. Make sure to take your time, and if you get frustrated just take a break and tackle it again.
12. I finally could get enough clearance to see the washers. There is a little part that goes above the washers, this part was stuck so one washer could get in but the second(longer washer,sandpaper thing) couldn't fit.
13. I KNEW THE PROBLEM THEN YESSSSSSSSSSSSSSSSSS. That was the problem, You just need to take it apart to see everything, but take your time.
14. I turned on the printer and VOILAAA, no more error. Although it did have an error saying the ADF was open. No worries once you close it up it works.
15. Thanks all!!!!!!!!!

So, we have a MP800 that is not powering on. Before this occured, the printer was not printing black (text) and I had just replaced the yellow cartridge (not genuine, but not the first non-genuine I have used in the printer). No obvious explanation, no power surges that we are aware of, have confirmed that the power cord works (have a canon digital camera that uses same cord for recharger), so it must be the printer itself.
Have removed what appears to be an internal power unit/battery where the power cord plugs into. Before we try to locate a replacement, want to see if anyone has any other suggestions, as we are obviously not 100\% certain that replacing this 'battery' will fix the problem.
Can anyone assist?
by unknown on May 14, 2011 at 4:56am Add comment
kadeandnaz,.....The Canon printers have a High voltage or short circuit power protection function built into the logic board. That is to say, "It will shut the machine down if it detects any problem associated with the High voltage used to drive the printhead. If the printhead has an internal short, the power will not be turned on. Of course this could be exactly what you have suspected,...the AC adapter is dead.

First make sure the printer is unplugged. Open the top cover and see if you can move the carriage away from the home positon (if it is locked in the home position you can't move it). If you can move it, unlock the printhead, remove the ink carts, and remove the printhead. Now lock the carriage handle, close the cover and plug the power cord back into the printer and see if you can turn the power on. If you are lucky the power will come back on, and this will have proved that the "Short" was inside the printhead. Once powered on the printer will flash "Orange" and ask you to install the printhead. I would not ever put back the old printhead. Buy a new one.

One day a month ago, suddenly out of the blue, we lost electticity (no storms) for about 5 seconds. when I went to print, I notice my printer never reset when the Electrictiy came back on. So I press the on bottom, and unplug and re plug

Nothing turned back on.

I unplug every thing. waited 5-10 minutes and replug every thing

Did my faithful printer passed or am I missing something?
Please help me as I can not find another printer and i had just purchase whole sale the Generun Ink cartridges.

donitabird,... It really sounds like your AC Adapter inside the printer has been damaged. They cost about $30 when you order them by phone at Canon Parts Department. It is very east to replace as is is removed from the printer from the bottom of the machine. As you face the front of the printer it is located on the bottom at the left rear of the printer. There are two finger clamps that hold the unit in place. Once your release the spring loaded clamps the AC adapter will lower out of the base. However, it is still connected to the printer by a small connector which you can pull loose. The Phone number for Canon Parts department in the US is 1-866-481-2569. Tell them you want to make a Credit card order, (since you don't have any other account with them) Make sure you tell them your printer model number and let them look up the part number.

I have this 6A00 error and have tried to fix according to the above posts. I seem to be stuck. My printhead is able to slide back and forth, and I removed the printhead and gave it a thorough cleaning with windex. Also cleaned the little sponges and sprayed some around the white slide-lever mechanism, which was sluggish, but now slides freely. However, when I power on the printer, the printhead (with none of the cart's lighting up) will not move and everything sounds like it is cycling but then stops. When I then check beneath the printhead, I can see that the white slide-lever has come part-way forward and stopped there. If I apply a slight pressure on it, it will slide back freely. Also, the sponges seem to be in a springy tray that does not stay down (ie-I can push down on it and will spring up), so it is not all the way down, nor all the way up. I am not sure what else to try. Is the purge unit right beneath the sponges? Can I remove it without disassembling the printer? Appreciate any insight.

HELP!!! Okay, so I know nothing--absolutely nothing about printers. I attempted to follow the directions regarding moving the printhead to the left and sliding the purge unit back and forth (the white plastic piece with little wipers??), wiping the wipers off, pressing down on the dirty pads (one long and skinny, the other more rectangular and small)....turning the printer on and off...Looking for jammed objects....Now, I STILL get the 6A00 message AND the printheads do not slide or respond AND the ink cartridges do not light up at all. When I open the printer the printhead does not move to the center like it's suppose to. Did I damage the printhead drive or belt in moving the printhead? HEEEEEELP!!!!! I can't afford a new printer and I actually love this printer (perhaps because I don't know any better??).
by unknown on Jun 12, 2011 at 12:02pm Add comment
Pixma Fan,...I can't tell if you did everything right, but most of it sounds OK. If the printhead does not move to the center once you open the top cover, you could see if it would move by hand "ONCE THE POWER IS OFF". It will never move by hand with the power turned on. If you did try and move it,..it would have been extremely hard and still would not have moved,...unless you striped the teeth on the drive belt.

It is totally understandable that you can still have the 6A00 error as something inside the purge unit is damaged or jammed. you probably won't see it until you take the printer apart.

I've had an MP830 sitting here for months with A600. I found a service manual online and took it all the way apart today.


To the right of the purge unit is a small white gear that is partially exposed. If you turn it from the top toward the back of the unit it will operate the entire purge mechanism. As I did this the purge mechanism went through its paces. I did it several times and put it back together.

After plugging it back in it started up fine. It's printing but some lines through the black text and no color but I'm doing some head cleaning to see if I can get that to work properly.

But, it does start up, scans, and prints!!!

sgf323,...Congratulations on your work. The manual cycle of the drive gear of the purge unit is one of the key thing people can do to cycle the purge unit and get in back in sync after something has jammed in it. However there were dozens of other things you should have cleaned and checked once you had the cover off. The purge problem will come back if you don't clean the entire purge unit,.. and as you are down there you should have taken care of the waste ink pads.

OK. Just one more variation on this problem.
I have successfully found and thoroughly cleaned the purge unit. It was originally stuck and the white part wouldn't move. Now it moves freely. I have cleaned ink from all around it and it appears very clean.
I never did find any debris or obstruction, just a lot of ink. When I open the unit, as if to change ink, the cartridges are not fully to the right, but they also don't come centered or light up. When I turn the unit off, I can move the unit freely left and right. In fact, with the unit on, the cartridges will move freely.
The cartridges do not "illuminate". Should they?
When I push the cartridges to the right, close everything up, and turn the unit on, copy button flashes, same old 6A00 error . . .
When I then open the unit, the ink cartridges are in that same position to the right of center, but not parked.
I would REALLY not like to take this printer apart, but I can not replace it right now, so . . .
Ideas, anyone? Help greatly appreciated.

pamelaw,...Congratulations on cleaning the TOP of the purge unit. Unfortunatley the 6A00 (purge Jam error) is still with you. You are lucky that the jam or obstuction with the purge unit is not the typical situation where the carriage has jamme in tight with the purge unit. Your condition is somewhere deep inside the purge unit,... and the only way to find it and hopefully fix it is to take the printer apart. I havee send you an email and once you respond to that I will be able to send you more information.

I've had the same 6A00 error on my MP830.

I've been unable to clear it using all of the steps from this thread.

I've taken the unit apart using the service manual, and stopped at just having the base unit and not the side circuit boards.

I can't find any sort of paper or object to clear out, and thus far i've been using alcohol pads and used a pair of tweezers to push them into the crevices in and around the purge unit to try to catch whatever it is, and only once have I seen any sort of hope. Once, the print head assembly actually moved a couple of inches from the right before the 6A00 popped up again.

I also noticed from reading, that the small exposed gear the runs the purge unit back and forth doesn't have a continuous motion as either Trigger1937 or BAB suggested. I turn it torwards the back of the unit for maybe 5 or 6 turns and then it can go no more, then I have to turn it the other way 5 or 6 turns and then it can go no more, and then I can turn back in the original direction (torwards the back).

Is that normal or abnormal?

When I turn the printer on, the paper feed gears spin and raise up and down, and the print head assembly does the same, and then I see the gears for the purge unit spin for a few seconds and then the big black unit in front of the purge unit that looks like a motor bulges to the right and then the gears stop at the same time and the 6A00 error comes up.

I hope you guys have some suggestions, as i'm about to give up, i've tried everything else on this forum.

as you mention, the unit goes in a continuous motion.
I took the purge unit itself apart and found that one roller inside was disarranged. I succeeded in arranging it properly and then the gear could be moved continously.

for some odd reason, my printer suddenly decided the blue ink cartridge was the wrong one. Took it out, put it back in. Same thing. Did this several times, then message changed to "cartridge not installed". Thought it had gone bad, bought new one. Still get error. Looked online and found info on cleaning the print head. Blue ink head seems to be the issue. When I turn the head over there is blue leakage from the sides. Not where the ink comes out, but between the metal area and the white piece it is mounted on. A replacement print head costs more than a new printer! I have a Canon MX700. Does this sound like the head has gone bad? After I put it back in and tried to reset everything, and it still did not work, I took it out again, and the bottom was very dirty. Lots of ink. What is this about rinsing the ink head cleaning pads and do I really want to go there? Thank you for your time and attention.

Hi, my Pixma MP 800 has a jammed ink carriage, down at the extreme Right end and therefore won't switch on.
It seems I need to dismantle it to free it as I cannot move it by hand easily, as I normally could. Can I get some directions from someone as to how to dismantle as little as necessary to get visible access to clear the obstacle please?
In anticipation, many thanks..
by Ropata on Aug 28, 2011 at 9:12pm Add comment

The cartridge being stuck isn't the issue.

Check for paper stuck, and if you still get the error, it's a problem with the purge unit (black unit on the extreme right which the print head assembly rests on) not cycling properly.
by coltoasty on Aug 28, 2011 at 9:22pm Add comment
Ropata,...Is it really a jammed "Ink Cart" or a jammed carriage. To get a jammed ink cart, the cartridge would have to have come up out of the craddle and if in fact it is such, the jam would have occurred before the carriage was able to get to the part position. This is near impossible. One way to check is to open the cover and see if the carriage can move away from the home position. Then pull out the power cord and see if you can move it by hand. I think what you have is a jammed carriage with the purge unit. This happens in many different way.

Hi again, I responded to 3 offers of more information to help me out but maybe they weren't received as I haven't had a response from anyone again. Consensus is that it is jammed with the purge unit somehow. I need instruction where to start & what needs to be removed to get a look inside.
Thanks, Ropata

A long piece of grey sponge with teeth like cuts into it popped out of my machine a few weeks ago. I thought nothing of it, papers get stuck every now and then. One did again, but the machine worked again after I pulled it out. Then the sponge popped up and I didn't know what it was, and pulled it out. I still have it but don't know what to do with it.

Soooo, after a "your print head is incorrect" (there was no other thread close to this problem, that I saw) message I have soaked up the ink on the little sponges, tried in vain to find a white rubbery/plastic thing that goes front and back . . .didn't really see anything like this. Also, turned the thing off, unplugged it . . .took out the print head, cleaned it with water. . . am now soaking it in hot water. and just sprayed inside of machine with organic glass and surface cleaner . . .who knows where my windex is . . .

Thing is, after i cleaned the print head with q-tips and water, and installed it into the machine, now the machine clcks steadily. Annoying, can you or your manuals help me? I am in mid project and deep into job search and I print stuff out ALL the time and scan stuff and right now i can't do ANYTHING!!!! I think the printer was three times what a refurbished print head would cost today. HELP!

Many times it is simply that the head area has gotten dirty.
Try these simple steps:
Take all the ink cartridges out.
Lift up the locking plastic lever to the left of the cartridges.
Remove the printhead (the holder of the cartridges and the print head is a black plastic container that will be easy to remove once you lift up the lever).
Clean with the head with a lintless paper product (toilet paper or non treated tissue will work fine).
Reinstall printhead.
Put the plastic lever on the left back down.
Reinstall the ink cartridges.

Hopefully all will be fine.

i also can just tell you what worked for me:

- i put the cartridges basket to the left
- look for a white part on the right side, the max right position of the basket if it moves normally
- i used my finger to push the white part back you will feel that there is a spring mounted and the white part is not coming back to the front again
- used some piece of toilet paper to clean the position where the white part was before
- resetted the printer
1. hold reset/stop button
2. hold power button
3. release reset/stop button but hold power button
4. press the resetz/stop button 2 times
5. release the power button
6. wait for service menu to display idle
7. turn the printer off and use it such if nothing ever happend :P

After trying all those techniques the 6A00 error didn't disappear... So I tried a different method.
1 - Turn the printer off
2 - Punch the printer twice in the top right corner
3 - Turn on the printer

It is working fine now, no problems at all. The error is gone.

imperyal,... You're happy now because "The error is gone". However this will be short lived as your error condition will come back. Because of the description of what you did,..and the results you got,... I know what the problem was,...but it will be back,... I guarantee it.

The problem is that the purge unit wiper blades are saturated in old, sticky ink build up. Each time the printer is powered on it does some basic test,..one of which is to wipe the bottom of the printhead using the wiper blades to clean off any excess ink build up. After many months or years this accumulates and both the movible wiper blades and the front fixed wiper blade get very sticky in old ink. sooner or later the wiper comes forward to clean things and then the blades get stuck "Extended". When the printhead is then moved back to the home position it jams into the extended wiper blades and you get the 6A00 error condition. Sometimes you can free the blades by hand by just touching them with a wet paper towel,.. of if you hammer the top right side of the printer with your fist,..it can do the same thing. However,..in the very near furture it will stick again,... and next time the jam may be so bad something breaks.
by unknown on Sep 29, 2011 at 8:35pm Add comment
Chris,...The action of depressing the pads is intended to do one thing and that is to "Free" the stuck state of the purge unit. Many times the old ink accumulates on all parts of the purge unit and eventurally builds up and turns to "GLUE". When your "Broke the bond" of the glue it really did not get rid of the problem. You really need to clean that purge unit or next time the wiper blades will stick when they are extended and then the Carriage will "Crash" into the blades with full force as it tries to move back to home position. I will send you and email and once you reply I will send you some instructions in PDF format on how to clean this area.

I got this error on an MP830. I figured it wasn't a paper jam since it was the first time in a few weeks I was printing anything. Turn off the printer and open the replacement ink compartment- move the inks holder far to the left- shine a flashlight in there on the right and you'll see that there is a sponge a tiny rectangular shape come loose -use the tweezer and put back in place. Don't know if it will work for everyone but it worked for me!

anon6963,....You got the error because of the lack of printing. After a long period of use the inside key parts of the printer have accumulated a lot of ink,..which begins to dry and get sticky. It almost turns to Glue. When the head sits still for two weeks on those pads,.. they almost become "Glued together". Now when the printer tries to do normal things the pad sticks to the bottom of the printhead when it moves away from home. You got lucky since the pad was not DRAGGED very far and you were able to find it. Most people don't even look in that area and just give up. That pad could have been dropped down in the bottom of the printer,...and then nothing would work.

The solution is,..print something everyday,..or at least every other day. Print a nozzle test print if nothing else. Keep the printhead in top condition.

We are having problems with our MP530 printer. We keep getting the 5c10 and 6a00 errors. We have opened the printer and moved the printer head looking for foreign objects and found a piece of paper and what appeared to be a piece of plastic packaging. After removing these, we check the purge unit and it does not appear to be stuck in the up position. Also, we did find that the printer head does not come to the center when you open the top cover but we can manually move it left and right with ease. We are looking for a service manual if anyone knows where to find one.

raybanslady,...Try pulling out the power cord and letting is sit for a few minutes. Then put it back and power it on and see if you get the same error. If you in fact have removed all of the obstructions from the carriage path and the purge unit the error should go away. I will send you an email and if you want more information about how to get a Repair Manual and a Service Manual, just send me a response. I will then be able to help you with more information.

Followed most of the suggestions on here for my MP530, I think (too many to read all), to no avail. Then found this link: http://tricks-collections.com/solution-canon-pixma-ip4300-error-6a00/ which has instructions *and* a wonderful photo. Just one (well, really 2 in 1), but with appropriately placed arrows and nice directions. Worked first time I tried it, and then I could see some of the parts posted here that I couldn't find before. Note: will *need* a glove to accomplish this if you don't won't ink ALL over the place.

Thanks for your posts; they got me going in the right direction.

Ta Da,...You were very lucky that you did not have the serious problem with the collision of the carrige and the purge unit wiper blades. Many times this jam can cause the wiper blades to be knocked off and dropped into the bottom of the printer. Also the carriage becomes so jammed into the purge unit that the only way to resolve the problem is to take the printer apart. For years I have provided upon request a much more detailed set of instruction to clearn the 6A00 and 5C00 error that occurs in dozen of different model Canon printers. While the link you provide is very helpful,..I have to laugh at the instructions such as; "This little white thing was stuck so move it back and forth"

I'm very pleased that it worked for you.

Had this printer for 4 years and never a problem (except sucky inkjet prices), then got 6a00 code tried moving ink head manually several times , no results , tried cleaning ink jet milker which is where this fault comes from and there is a small peice with 2 sponge squares on it , it was jammed at a 30 degree angle pushed on it with q-tip and it went back down flat problem fixed.

GI,,...You were lucky this time since the jam only twisted the ink pads. What will you do next time when the entire carriage jams into the printhead. Do you know why it jammed and did you resolve the problem that caused the jam. I doubt it.

paolaceles,...Thanks for the post and link which does include excellent pictures. This fix does work and is the same thing I have suggested many time. It will work on any Canon printer that use similar printheads-purge units. The wiper blades get totally saturated with old excess in they have wiped off of the bottom of the printhead and eventually this ink begins to dry and become sticky. Sooner or later as the blades move forward to wipe themselves under the front bar the blades get stuck "Under" the front bar. This happens because the spring that is pulling on the blade are is just not strong enough to return the blade assembly back to the resting position. During all of this "Cleaning" process the carriage and the head have been out in the center waiting until the cleaning was done. Since the printer does not know the blade is stuck and things the cleaning cycle is over it moves the carriage back to the home position and "Bammmm",..you have a jam. The real solution to all of this is that these wiper blades and the purge area need to be cleaned of excess ink every now and then. Hope this helps others.

I'm new to this forum.
Got the problem that everybody seems to have with my pixma mp610 today.
A paper got stuck, there was some loud noises coming out of the printer, after that the error code 6a00 was showing in the display and have been doing so since, tried to unplug the powercord for a couple of minutes but didn't help.

Would appreciate if someone could help.

best regards!

Had this error code come up. followed most of the advice given here to no avail. It would work sometimes but then show the error again.
Pulled it down today and found that the front roller in the tube pump had broken its carrier and was jamming up inside.
No easy fix I'm afraid.

Hi ya'll. Just happened to this blog and found it very interesting. My MX850 got the 6A00 error this morning as I was trying to add paper to the tray. Not trying to print yet. Couldn't get it cleared, so gave up turned it off & unplugged it. We come from the school of "if you're not using it; turn it off." So, our printer could set OFF for several days to maybe a couple of weeks.

After hours or so of reading here, I managed to glean enough to at least know what to attempt. It is getting far too late for me to tackle tonight, but will give it a go tomorrow.


EDIT: Well, I thoroughly cleaned the print head under warm water in the kitchen sink! Yep, it was a mess. I also cleaned the right side area that was in the picture mentioned above. When I powered up, NO MORE error code. However, upon cleaning (via software) and testing the print quality, everything went well except the BLACK print was missing. All other colors were just fine. Well, like everyone else in the world, black is the one I need the most.

So, now what to do? Do I go back in and clean more with a focus on the black area? Run the tests again, and again to unclog something?

Give me some direction, please! Not sure what I am supposed to do, as I read about sending "trigger" an email. Guess I'll send this directly to him, as well. Sorry if that's a "no-no!"

Addendum to my earlier post;
Because the tube pump roller in the purge unit was broken there was no easy fix to the unit. Canon advised me of an online supplier for the parts needed. I purchased a new purge unit and absorber pads on line for AUD80 delivered, fitted it all back together and the printer is working like new.

I tried nearly everything short of reassembling the entire MP830 "infrastructure". I found no sponges in the ink cartridge carriage and tried cleaning the printing spools, and so forth and so on, and from what I can tell, asking for Canon to help is not very helpful or enterprising for either party. This said, I took my 7 year old Pixma out to the city recycling center and "trashed it". I went to Best Buy and bought a new wireless series 8600 HP printer for $125 (on sale) that has all the bells and whistles of the MP830. Most of you all seem to have owned such model printer for approximately 2 - 3 years. They must now have planned obsolescence. Printers like computers and high tech electronic stuff these days don't last forever. They are making this stuff cheaper and cheaper all the time. I would not bother working so hard to re-build a broken printer. Heck, you probably spend enough money during the life of each one you own in ink cartridges each year (of ownership), not to mention paper. I thought my Pixma was a pretty good work product while it worked as I was a "slave driver" to it: I write reports, am on the e-mail and web all day long, run my home based business (consulting) using it and my HP Windows 7 computer kit. Some of you all may be die hard enthusiasts and don't see the urgency to replace the original MP830 (does Canon still make this model??). I don't know, but in my view the bottom line is "if it IS BUSTED, Or NOT BUSTED, in either case, don't try to FIX IT. Our economy is so disposal oriented now that it is always cheaper to replace it (recycle)a broken computer or printer or electronic apparatus than to go to any lengthy, complicated or extraordinary initiative to have it repaired, but yes - I agree if Canon will send you a new one - then that is a different scenario, but it is now perfectly sensible and appropriate and cost-effective to "trash the broken machine" and go to Best Buy to get a competitor brand. Just be sure you tell Canon you are buying HP and then they will manufacture printers that last since like any business enterprise they don't want to see their profit margins slip to competition firms that are starting to assume greater market share because they, Canon, have been too irresponsible to offer customer friendly over the phone repair advice as well as sell us consumers inferior printer products.

Some of us enjoy the challenge of repairing equipment rather than assisting the throw away society that you so love.
Added to the satisfaction of fixing what was a very good printer was the fact that I had around 50 ink cartridges which also would have been throw away had I not done the repair.
I was quite confident that the fix would be successful and it turned out way cheaper than a replacement, as well as providing a modicum of entertainment at the same time.

Ballantine,...You are entitiled to your opinion,..but just because you failed don't try and convince others that fixing things is a waste of time. You and people like you are the reason that city dumps are full and over flowing and we have to spend more money to ship our trash to other places. You are the one that killed your printer,..you even admit that you were a "Slave Driver" for 7 years and I can be that you never did anything to clean or maintain that printer. The few things you did try to find the problem demonstrated you did not have a clue on how to find or fix the problem.

There is no such thing as "Designed Obsolessents" and you proved this yourself. Look at what you did to the MP830 and look how long it lasted. I bet you that whatever was wrong with it, it could have been repair. Canon "IS THE ONLY MANUFACTUER THAT STILL PROVIDES SERVICE AND PARTS FOR THEIR FAMILY OF PRINTERS". Some of the problem was not your fault since no one ever told you how to maintain the printer.

Right now you think you are very happy with you low cost HP,..but just wait until you find out how much the ink will cost you,..and I will bet you the cost of a new printer that your HP will be dead in less that half the time your Canon lasted. Here is the bad news,.. whatever happens to it,..you won't be able to buy "ONE" part,..nor find anyone willing to fix it.

For all the "Other People" that read this forum,...yes there is a time when you have to send your printer to the recycle bin,..but the best thing you can do is learn right now "HOW TO MAINTAIN YOUR PRINTER ON A DAILY BASIS" so it will last as long as possible.

I've tried everything mention here, except I cannot see or feel anything which looks like a sponge. When I push what I assume is the purge unit it moves easily; I have wiped out as much ink as I can. When I push back the purge then turn it back on the purge comes forward all the way. The ink head will not move by itself. I touched it when I turned printer on and I felt no vibration or slightest movement as printer made normal startup noises. There was an extra noise however. In the middle of the startup there were three quick buzz-like sounds coming from the far left side of the printer. Desperate for help; not a good time for me have to buy another printer.

After reading the error messages on here, I decided that I would move my printer head to the right and put my hand down and under where the printer head usually sits.

While feeling around in there I felt that there was a small ink spill in that space.

So after wiping the ink up with my now blackened hands then switching hte printer off / on yet again, the error 6A00 has now gone.

I hope this info can possibly help others.

austux,....You are smiling now but that error will be back. Your discription tells me that your purge unit is just about saturated in old stick ink and if you don't clean it soon you will have a serious JAM. What will happen is that at one point the purge unit wiper blade will stick out extended and the printer will be printing a page. When it is done it typically waits for 30 seconds and then moves the head back to the park position. At this point the head is moving pretty fast and slams into the extended wiper blades and they may LOCK together. Once that happens you will get the 6A00 error and you can do NOTHING except take the printer apart. At that point you can send me a note and ask for some help.

I got the exact scenario you described. I've got a 6A00 on my MP800R. The print head assembly now appears to be stuck on top of the purge unit.

I've found the Service Manual for the MP800R which has some disassembly instructions, but if you have anything specific to point me to I'd be interested.

Kangaroos hopping down the main street is not an everyday event (to the point where the state-capital city, Perth, installed a few brass hoppers on the sidewalks of Saint George's Terrace, the main street, specifically for the terrorists ^H^H^H tourists), however, we also get amazing Tawny Frogmouth "Owls" (actually Nightjars), another marsupial slightly larger than a house-cat & an order of magnitude more elegant known as a quoll, big wingless birds (emu), birds that laugh (kookaburra) & crazy parrots (one example being galahs), & (in the Sound outside my home town of Albany) Humpback & Southern Right Whales.

I wound up disassembling the printer to retrieve a wayward piece of plastic junk from inside the purge unit. Not so simple.

Now breaking out the soldering iron for making an adaptor from the printer port to talk to the toner cartridge from a Samsung laser. & hoping that the (binary-only MS-DOS) software to reset the counters will work in DosBox.

Thanks for the hints, Trigger.

I am having the same issue,

When I boot up the printer I am greeted by the error 6A00 message. Before the message occurred, I had ran the preventative maintenance included in the printers software. A piece of paper had ran back and forth a few times, and now the printer has become unresponsive. Any help would be greatly appreciate.

I began the troubleshooting process when I got the 5100 error code. After searching, surprisingly finding, and then removing some old, crumpled paper on both edges of the carriage, I felt certain my trusty MP 830 (not kidding... loved it for the past 6-1/2 hard-labor years!) would be right back to work. Not so. Next time I fired it up I got the 6A00 code, which is not handled in the handbook. Luckily the first stab at an internet solution got me to you all. I got a flashlight and tweezers and began poking around the purge unit, which was very gunky. After lots of turning on and off and moving the print cartridges and holding my head in my inky hands, I noticed a teeny, tiny corner of something that didn't look like it should be there. So I pulled on it gently with the tweezers and out came one of the tabs you remove on a new ink cartridge! Put the pads in place (they were also slightly dislodged) on the purge unit and tried everything again. Lo and behold... it worked. So I cleaned the nozzles and printed out a test page, which came out perfectly. I thought I was a genius! But I got the old 6A00 code immediately afterward and it has been puzzling me ever since. My only thought is that the spring is having a hard time operating with sticky ink in the channels, so I'll try the windex cleaning route and go at it again. At least it showed some signs of life... thank you for all the tips.

While the people above have the technical jargon, I will dumb it down for you and tell you how I fixed the same issue.

1)power off and unplug your printer

2)remove any paper trays and paper from the printer

3)open and visually check all access panels and rollers (inside and out, top and bottom, front and back) for paper, paper fragments, foreign objects, and broken plastic pieces or missing springs.

4) Open the printer to manually load/unload the ink cartridges. Remove the ink cartridges by lifting the gray lever on the left, and carefully removing them one at a time. Also remove the cartridge carrier assembly which is the piece at the back of the 'print head assembly' - the thing that travels back and forth. It will just lift out. Now lower the gray arm on the left and manually slide the print head assembly all the way to the left and out of sight.

5) Grab your flashlight and look inside the printer to the right and notice the 'purge unit' or spittoon. It will most likely be covered in gunk and ink. CAREFULLY wipe off any excess ink with a lint-free cloth (I used an old white t-shirt) being sure to be EXTREMELY CAREFUL of the delicate moving parts in there.

6) My issue was a dislodged 1/2 X 3/4" piece of foam/filter which lays flat at the bottom of the purge unit. CHECK THIS. make sure it is secure in it's little holder. While you are in there, check for missing/broken pieces as well. I suggest using tweezers or long need-nose pliers to get in there CAREFULLY.

7) Grab your cartridge carrier assembly and flip it over. You will see a bunch of metal pins at the back and some delicate ink nozzles on the bottom. CAREFULLY wipe all the gunk off of these nozzles with your cloth and make sure the pins are clean for good contact with the matching pins in the printer. Those send the electrical signal to the ink and tell it when to spray.

8) Replace the cartridge carrier assembly and ink cartridges into the print head unit and close the lid.

9) Go into the settings and utilize your "print head alignment" and "nozzle check" maintenance features.

10) PRINT and be happy!

The post above by ARMM does have some good suggestions but many times the 6A00 error is caused by the carriage (and head) being jammed with the purge unit, or LOCKED in place by the purge unit. In this condition it impossible to execute step 4. Many people will also find it very hard to perform step 5 as all of the purge unit it located underneath the internal cover on the right side of the printer,..and as a result there is very little access to the purge area. What ARMM found in his printer was the Black ink Pad which had somehow come loose. It is a critical part and if it had dropped down into the bottom of the printer ARMM would have had to totally disassemble the printer. If he had not replaced it correctly the printer would have never worked again. The only way step 9 could be executed is after the printer was powered on and completed a full diagnostic cycle and cleared the initial 6A00 error code and brought the printer back to "Full Function" and "Ready" mode.

If you are not this lucky and are still having problems with the 6A00 error code, click on my USER ID and send me an email. I will respond with the correct TECHNICAL information.

Help please. My printer wouldn't work so cleaned the ink in the purger area. Worked for a bit. Then stopped again. The head was stuck. I managed to move that by sliding a plastic spatula underneath. I thoroughly cleaned the ink around the purge area and tried to print. Now it tells me I have a paper jam! Any ideas

Anton,... You need to be a little more specific. What was the error code for the paper jam. I am sending you this short email and when you reply with your email and printer info I will be able to send you the instructions you need.

I have the same issue everyone else is talking about - Error code 6A00 - it happened right after printing a document on 2 sides of paper. I opened up the unit, see the purge head pads - they spring up and down freely but are a little ink soaked - there was the sliding mechanism behind these but it doesn't slide past the purge pads which are sprung in upward position. Not sure what to try right now.
by lnmkbd on Nov 21, 2013 at 5:09pm Add comment
Inmkbd,....Sorry to hear about that but hopefully it is not as bad as other problems. The error is mostly caused when something is dropped into the carriage path,..such as a paper clip, staple, hair pin, etc,...and is pushed into the purge area where it can cause a jam. I will send you this email and when you reply I will be able to send you the files you need to hopefully clear this error. when you reply to this note mention the MP800 and the 6A00 error condition.

A special thanks to username brice and username BAB for posting fix-it-yourself ideas. After checking about 500 times for a paper jam, I came to this page and saw their suggestion. I moved the print head and pushed the white "thingy" back and forth a bout 5 times and it is now working.

I also had the 6A00 Error on my aging MX7600. The pushing-the-sponge-down trick did not work for me. What finally did work involved a part just to the right of the sponges that the print head parks over. Its a white plastic piece, Mine was stuck in a forward position. After much poking around in there, I realized that this piece can slide toward the rear of the machine. And for me, that was what had to happen to get past the error message. Just pushed it toward the rear as far as it would go, slide the print head back in place and it finally started up normally again. I hope this helps anyone out there who might still have one of these still working.

Do you own a canon wireless printer setup that you just bought? If you answered yes, you must first properly set up your printer at your office, as you will only be able to print, scan, or fax the paper after that. Setting up a printer for the first time can be difficult for a non-tech or newbie, which is why we include a link where everyone can get precise instructions on how to complete the setup process in a more efficient way. Because this paper is meant for people looking for a printer setup guide, you can also read the blog.
