Canon MP530 - 6A00 Purge Unit?
I keep seeing postings related to purge unit being blocked maybe, but i can't quite figure out what or where the purge unit is on my canon mp530?
Don't want to spend $55 for someone to just look at it, if i can fix it myself ...
1) Reading above ... You have done the hard work it sounds like.:) Gathered together some pdf.manuals and photos providing step by step instructions for fixing the CanonMP530; error message, "6A00 Purge Unit" ... cool ... I need help getting at the purge pad or deposit reservoir for black ink and washing it. Similar idea. Can you help?
2) Is the manual more than one, or can you give a general idea how many pages I might have to review before a natural understanding of the fix is made clear? I know everybody is a different learner. Can you give me a basic or general idea how many pages or if it is all in many different manuals with other printers bunched together?
3) For the error I have mentioned above, 6A00 Purge Unit, how many pages are involved in the solution; more than 10 or 12 pages? Just curious. Thank u.
I am a woman trying to fix this printer. Did not want to send it in to Canon for fix due to cost being unreasonable. It is a good printer though and I hate to just leave it unattended. If I can do this maintenance work, cleaning ink and washing a pad inside, I will like to determine the first time to have someone with me, but the next time, I might be able to do it myself.
Thank you for your consideration.
Open the cover and when the head comes to the center pull out the power cord. Now you can freely move the head to the far left and out of your way. The Purge unit is on the right. Use a flashlight and you will see two ink pads. This is where the printhead is PARKED,.. and is the top of the Purge unit. There are wiper blades that move from the rear to the front that wipe the bottom of the printhead when it is parked (The ink pads actually drop down about 3/4" to allow the wiper to pass,..then it supposed to SPRING back to the rear. All of this, and the ink suction for cleaning the printhead is done by the purge unit,... one of the most complex parts of the printer.
Use some rubber gloves and a paper towel and see if you can press the ink pads down just a little bit, like 1/4". See if for some reason the wipter blade is stuck extended,.. if so see if you can get it unstuck. Don't force anything, just be gentle.
The error you are getting is telling you that the purge unit is not giving the correct timing signal as it rotates inside 360 degrees. Therefore, something is either broken or jammed inside. If you had a paper jam and tried to forcefully pull it out, you could have pulled the internal gears out of alignment.
I can send you a picture of the Purge unit and a picture of the inside of a MP530 if you send me an email with your address. Just click on my USER ID and you can send me a direct email.
I also sell a complete Repair Manual for specific Canon, HP, and Epson printers. I don't have the MP530 yet but I do have the MP730, and the MP780, and the Service Manuals for the MP800, MP810, MP830, MP960. My Daughter has the MP530 but for some reason she won't let me take it apart. But since I'm going down there next week, I take the necessary pictures needed to get the covers off. Once the covers are off, my other manuals are good for the rest of the repair. My manuals are detailed instruction manuals with Digital pictures to show you each step to totally disassemble and repair just about anything in your printer. There are no miricals, if something is broken you can buy a new part from Canon and put it in yourself. Take it to a Canon Repair Center and any Multifunction printer will start at about $100 just to take it apart. Mine also comes with the complete Canon Service Manual(if i have them) and all Canon documentation such as Product Service Bulletins, software drivers, installations disks, User guides, and several other documents that teach you how to take care of your printer, clean the printehead when they get clogged, and maintain the printer on a day to day basis such that it will last for years. In my opinion Canon Printers are the best. They are easy to fix and you can get just about every part from Canon at reasonable prices.
Hope this info helps you out.
its going to be 1 of 2 things
most likley is
1) somthing is jammed in purge unit. even a small tear of paper will upset it
2) it is logic board failure
Im putting my money on it being somthing stuck inside purge unit though
Thinking I was hosed i just left it turned off for the day. Turns out when the kids turned it on and tried it again, it works just fine. And low and behold, the little plastic piece was actually the top of a plastic pencil that my son had flung into the printer from the other side of the room. :-(
I still am not sure what to do with the little wiper blade, but the printer is working for now.
1. The excess ink is dragged across the printed paper and smears the page with streaks of ink.
2. The excess ink dries fast and cloggs the printhead.
3. The black ink on the color ink printhead can contaiminate the other colors and ruin the print quality.
You were lucky to get the jam out. However, to get the wiper blade back in place you will need to take the printer apart and take out the purge unit and re-install the wiper blade. If the blade is broken, you will need a new purge unit which you can order from Canon.
Read the post above if you want to find out how to get one of my manuals that will teach you how to get the printer apart and repair it.
Here is a re-post of the note you sent me.
I've got a broken purge unit in a Canon Pixma MP760. I've purchased a new one, but I now realise it is a bit tricky to replace. How much are your instruction manuals and how can I get my hands on one?
I had already given up waiting for your response and was today just browsing through the forum topics when I saw you've actually replied to my e-mail straight away! :) I should have been more frequent here, my mistake.
The e-mail address I provided is one that I use every single day. It is far, far away from any space quota warnings, so I'm puzzled as to why your e-mail would bounce back. No offence, but have you maybe misspelled it? For obvious reasons, I am reluctant to publish it in this topic, but could you please try resending (maybe using a different account)? I'll be checking for news here more often now.
So I have repaired my document and reduced it to usable size and have transmitted it to most of you. By tomorrow everyone should have a corrected copy.
As far as the last Anonymous post,..You need to be more specific. You tried what I said,... but I forgot already what I said. What is your printer, what is your problem, what specific have you tried?
Anyway, did you ever resolve your problem with the MP530. I would like to know such that others can be helped.
Please send me the photos that you say will help me replace the Purge Unit in my MP530. I really appreciate your help on this.
My Canon is putting a black stripe down the back of my printed pieces and it's either trash the printer or hopefully your suggestion to replace the purge unit will remedy this.
It sounds like your black ink cart has leaked ink down onto one of the bottom rollers. Open the cover, remove the ink and the printhead, pull out the power cord, then use some paper towels wet with Windex to clean out any spilled ink on the roller.
If you need more specific information or you want to take your printer apart, just click on my USER name and send me an email.
The MP530 is one of the best AIO printer on the market. I purchased one for my daughter so you know it has to be good. Be patient and we will fix it.
The print test fails miserably (black cross hatch portion only) and a head alignment error pops up when trying to auto align the head. I am 2 months out of warranty and CANON Tech Support suggested the Print Head to be bad. I replaced it and the result is unchanged.
Can the purge tank bad even though I am not receiving an error? I either need to fix this ASAP or junk it and buy another multi-function machine.
Any help would be GREATLY appreciated.
I doubt very much if you head has gone bad. Open the cover and remove and cap the ink. The pull the power cord out. Then open the carriage latch and remove the printhead. Take the head to your laundery room sink and turn on the water to full force and only hot enough that you can hold the head in the water stream with out burning your hands. Flush all the ink out of the top filters and turn the head over and focus the stream on the nozzles. Then turn the head back over and see which filter screens still have ink on them. Since you know your Black was clogged, focus on the large black nozzle group. Repeat this over and over until you don't see any more black ink come out from either side.
Once you have done that, gently dry off the head with by blotting
the head with a paper towel, and then use the Air compressor in your garage to blow all of the water out of every crevace on the head, including the back where the circuit board is located. You may have to let it set overnight to fully dry out all of the water.
Once you are satisfied that it is dry, clean the contacts on the back of the head with Isopropyl Alcohol and a tissue,...then clean the contacts inside the carriage asm,.. only wiping in a downward stroke. Those pins are spring loaded and sharpe and only bend downward.
Once you have completed all of these steps, replace the printhead into the carriage and close and open the carriage lock a couple of times. This wipes the two gold contacts and pads together and does a metal to metal cleaning. Then check your ink carts. Blot each of them on the bottom and you should easily get a good circle of ink. If not you either need to get a new ink card or clean that one. One thing you can do is to blow air into the air inlet hole on the top rear of the ink cart. Hold a paper towel under the exit port when you blow and you should easily get a drop of ink to fall onto the towel. If not, then your ink cart is getting clogged internally.
Once you have confirmed you have good ink installed, plug the power cord back into the printer and press the power on button and close the cover. ONce the printer settles down, RUN A CLEANING CYCLE AND THEN PRINT ONLY A NOZZLE CHECK. If you don't get good results, run a DEEP CLEANING CYCLE and then another nozzle check
After all of this effort, send me an email with a scanned image of the nozzle check and we will proceed from there. To send me an email, just click on my USER ID and send a note. You won't be able to attach any image as this web site dose not support attachments. ONce I respond to you email you will have my email addess and then you can attach the image.
Start with printer off
Press and hold resume Button (triangle in the circle) and click “Power” button. green led should be on
While holding the Power button, release the Resume Button.
Without releasing the Power Button, click “Resume” button for two times and release Both Buttons.
Click “Resume” for four times then soon click “Power” button, to confirm the selected action (reset counter absorber).
Turn off the printer and turn on again
Please see my post regarding resetting machine
Your instructions were correct, but not for this problem. You need to be careful on the advise you give as this also put the machine into "Service Mode", and you really didn't tell him out to get out of Service Mode. Others may look at this post and thing they need to RESET their machine, and in Service Mode you can screw up many things. For example, if he would have made a simple mistake and hit the resume button 5 times he would have changed the machine into Japanese language. I don't think anyone would want that.
It's ok to give your suggestions as everyone want to contribute but you should at least know that your information is correct before you give it.
I know that our current economy is not doing very well at all and many people are struggling just to get by this Christmas season. In my effort to do what I can, I have decided to reduce the cost of all of my Reapir Manuals by 30\% for the holiday season. It's not much but it is something I can do. If you want to know more just click on my USER ID and send me an email and I will respond.
You steered me in the right path! I looked in the rear turn around and found a push pin way in the back! It was way back in the center of the machine almost to the printer cartridges! I had to lever the plastic guides back and use a pole magnet to get the pin out. I would have never found it if you hadn't directed me were to look, even with this help, I barely saw the white pin. It makes sense now as to why I couldn't use the front or rear feed, but the pin was so far in I'm wondering why the paper only fed about 1 inch and then jammed, is there a sensor back there? In any case thank you for your help, I was about to buy a new printer and this one is only a year old and has had very little use.
I have the same printer from one of my customers, but I guess I'm missing something. I got as far as pushing the two inkpads down. After that, I'm stuck. I don't see a wiper blade sticking up. I have also tried all the cleaning options and nothing has worked. Are those photos still available? If they are and you can send them I would be in your debt.
Where I can find information how to replace purge unit.
It would help other if you would be more specific and detail what you cleaned and how you cleaned it.
I would like to open up my MP530 printer in order to see what is going on with the paper feeding mechanism...it was working perfectly and then out of the blue it suddenly stopped pulling the paper from the feeder into the printer...I've looked everywhere for stuck and jammed pieces of paper to no avail. So I would like to open it up to see if there may be some hidden inside it.
Can't find a manual for the printer any where...
Please advise, thanks
I know you looked very close to see what you could find, but you won't believe the list of things that I and others have found STUCK in the feed rollers,..everything from paper clips, staples, hair pins, pieces of string, your Cat's favorite toy, and one time there was a small dead mouse. So re-examine everything in the top side paper feed area, then remove the lower tray, then remove the rear door and use the brightest flashlight you have. What you are looking for may be very tiny and probably stuck between the lower pinch rollers.
To contact me for more info,..just click on my USER ID and send me an email.
Did you find anything at all in the upper paper feed area? As far as a visual diagrahm, this is what is contained in my Repair manual but you only want to go there if you know you really have to take the printer apart.
Remember, you could be looking for somthing other than paper, like a paper clip, staple, rubber band, or anything that your Cat could drop into the printer. One of the ink pads could be out of place and cause the same jam. OPen the cover and pull the power cord when the head comes to the center. Now you can move the carriage by hand. See if you can find any restriction by moving the carriage from side to side. It should take very little force and should be smooth all the way and you should not bump into anything. Make sure you ink carts are all the way down and locked into the carriage.
I'll check the internals tonight.
Thanks for the help!
Yes I'm talking about the Cannon Multipass 530
i've never loaded paper to the tray at the bottom since i never knew it existed. Besides the bottom tray doesn't seem to take 8.5 x 11 paper anyway, it seems to be for irregular sizes and envelopes only, so, i've always used the paper feeder on the top, in the back, with no problems, until now.
The feeders don't grab the paper anymore and when I start to print. Everything goes fine until its time for the feeders to grip the paper to pull it into the machine, because they fail to do that i get an error message that asks me to load paper even though there is lots of paper loaded. Examining it closely i can see that one gripper--on the left-- that is supposed to grab the paper and pull it through the machine are malfunctioning. How does one go about fixing that? How do I take the machine apart to get to it?
The print head doesn't move when I power cycle the printer so I can't catch it in the middle.
Is there a tear-down manual for this printer?
Getting feedback from this web site is very if'ie. I don't always come back when I'm out of time. You need to contact me directly by clicking on my USER ID and send me an email.
I have an MP 530 and have tried to follow all the instructions above. When printing from my computer, I receive a service error 5C10.
When I turn on my computer--it starts up as usual but when sending a print job--I receive the above message.
I have tried to clean the print head and quite frankly--do not know what to look for when looking inside the right side of the printer. I have called Canon tech--went through a series of troubleshooting and was offered a discount on my next printer. I love the ease of this machine and besides this incident--it has been running very well.
I have tried to make a copy but jsut freezes and the alarm light turns on and I receive the 6A00 message. I would love to fix this machine and needed it done by yesterday. Any help would be greatly appreciated...thank you
The 5C00 error is listed in the Service Manual but not the 5C10. It must be a subset of the main error. However it is all abour the purge unit and you need to try and clear the problem I have a test I want you to do and I will send that to you via email,... but I can't attach it from the web link. So once you get my email, send me a reponse and we will get it going.
You need to hurry as I'm going on vacation for 3 weeks.
The ink pads seem to move freely as does the wipers.
The only odd indication is my print head doesn't move to the center when I open the top, but I can slide it freely.
I don't know where you guys are getting the 6A00 codes.
What's next: take the Canon loyalty discount???
If you still have no luck, send me an email. The MP530 is a great printer,but sometimes they do need service. You may have to take it apart.
If you need a photo I can email it to you.
I don't see any debris in the vicinity of the purge unit either.
Did you do the other steps and were you able to move the head and check all the front area. Also check the timing strip for contamination with ink spots.
I am going to send you an email and once you get it send me any kind of response. This will give me your email address and I will be able to send you a document with instructions on how to test and clear the 6A00 error condition, which is almost always tied to a jam in the purge unit.
I slid the head completely left to right, no binding. Found nothing underneath.
Is the timing strip that clear band of plastic that looks like cellophane tape? If so, it had no ink on it.
I have your email and I'll respond no later than 12:55am.
I looked inside and cant see anything blocking the print head, I pull it out and soaked it in hot water. Still nothing. I replaced the larger black ink cartridge when through all the cleaning it showed being low. Any suggestions of other things to try? Oh and also If I copy color it works, when I do a nozzle check it prints a page, it prints one black line at the bottom after the different colors. Should there be two black?
On the print head is black only printing done through the single larger print head? Also does black only printing use the larger black ink reservoir?
Thanks in advance....
I tried to stay with my three year old MP530 but Canon couldn't do anything for me; their best offer, without making any suggestions as to how to fix my paper jam error, was to give me a "loyalty" discount (a pittance) for the purchase of a new Canon. Their lack of support convinced me to try a different vendor, hence the HP. Why would I be loyal to Canon when they had no sense of the same obligation to me?
Netgazer,...I'm sorry for the repsonse you got from Canon but what else would anyone expect when the product has gone out of warranty. If you still have the printer, send me an email and I'll send back some picture of the sensor and show you where it is and suggest how to fix it. You will have to get the top covers off to get at it.
All I wanted from Canon was either a way to fix it myself (and with all the paperjam errors they see, you gotta know they've got a tech bulletin) or a way to get it fixed. Their only answer was a repair shop over a hundred miles away. I wasn't looking for them to replace it, or fix it at their cost.
Now that I have your email address I will send the files.
Thanks for the information you sent. It turns out it was a very stubbornly clogged black print head. I had previously tried washing, but that had not apparently fixed the issue. Your windex suggestion did the trick to break it loose.
Now one final question, if the printer is not going to be used for a period of time, is there a suggested way to prepare it for storage so the print head doesn't clog up?
If you are going longer than that, remove the ink and cap them off with the original orange caps that came with the ink (use a rubber band to hold it on tight) and remove and flush all the ink out of the printhead. Use a plastic dish and set the head in 1/2" of water and leave it. The will keep it wet internally just in case you did not flush all the ink out of it. Use a syringe with warm water and flood the two ink pads where the head parks. This is done to flush old ink out of the pads down into the waste area. It should gradually seep through to the bottom. You could flood it several times and blot the pads to absorb and clean out the old ink. You don't want these pads to dry up.
When you come home, make SURE TO TOTALLY DRY THE HEAD AND BLOW ALL THE WATER OUT USING COMPRESSED AIR. If you don't have a compressor, dry the head using a hair dryer set on LOW heat and Max air. The main point is to get all the water out and away from the circuit card on the back of the head. Once you are satisfied you've done this, clean the contacts on the back of the head, and inside the carriage, install the head, install the ink and power on the printer. Don’t print anything until you PRIME the head with ink. From the PC do a cleaning cycle, as this will "PRIME" the head with ink, then print only a nozzle check to prove that you head is full of ink. If you need to, do additional cleaning cycles.
The first thing we need to do is "Prove" through an isolation test that it is really your purge unit and not some other problem. To do this I need you to send me an email, so I will send you one from here. Once you get it just send back a response and I will forward to you the testing that you must do.
I cleaned the purge unit - and all ok.
Then restarted the print job.
After a few printouts the same error - cleaning does not help anymore.
Could anyone help me?
Thanks - georg
I removed the external housing complete and also the bottom case.
Then i could remove the purge unit and clean it with water.
After re-assembling the printer it works without error.
(only forgot one screw for fixing the purge unit - hope it works without)
as a after though would I get a paper jam error if there was paper in the top feeder (the one on top of the scanner)
also a quick question in advance.. will this printer work without the colour cartridges in?? is there any way to bypass the startup so it will start on scan etc as right now that is what I really need to use it for (the missus dropped our other printer) or even skip to the fax
I hope you's managed to follow me :)
thank you in advance
The 5C00 error is very standard in all Canon MPxxx printer and it is telling you that you have a diming error or cycle problem with the purge unit. There are many things that can cause this problem, but you said you cycled the purge unit by turning the gears (I hope you turned them towards the rear)and you did not see the wiper blades come forward. This is impossible unless something is out of gear. One of the main function of the purge unit is to move the wiper blades forward and "Wipe" the bottom of the printhead to remove any excess ink. There is a spring attached to the wiper are and once the blades are moved forward they are released from the gears and the spring brings the blades back to home position which is far back out of the way of the printhead. That is also why the pads drop down durning the cycle to get out of the way of the wiper blades. If anything in the purge unit is out of timing with the cam and sensor in the bottom of the purge unit you will get the 5c00 error. You also should have checked and cleaned you timing strip while you had access to it. You should of had my Repair Manual.
There isn't any paper.. (i havent used the auto feeder for ages!)
Is it an error that I need to request service for? :(
I've also noticed there are a spring on the front side of the purge unit with a tiny little white tab that can be pushed forwards but doesn't really do anything. I'm just wondering if perhaps this can't somehow block the movements of the cartridge unit.
I've looked everywhere and there are no pins, staples, torn paper or cats toys.
Any help will be greatly appreciated.
I found this post because I had the same problem. I didn't have any black ink coming out of my MP530. I use the printer on a regular basis, so I was really surprised that I had a clogged or dried up purge unit. So my first thought is that maybe it was a problem with the brand of ink since I just switched to the office max ink instead of the canon ink....but we will get into that later.
So I concluded that my purge unit was clogged. So I bought the service manual on ebay, took off the 16,000 covers...and finally got to the purge unit. By the way...the manual does not tell you how to take out the purge unit, you don't have to take out the NCU board, the NCU sub board, or the logic board to remove the purge unit. Just remove the 2 screws that hold the metal bracket of the NCU board and tilt it out of the way.
I service the new Direct To Garment printers and we never use water or alcohol on our print heads or capping stations (purge units)because it sets the ink and does not help clean anything. But I tried using that because this is pigment ink, so maybe its different. No....I found out that it is not. So I used what we use all the time...Windex and it worked perfectly. It dissolved the ink so quickly and unclogged the line immediately. It worked so fast, that I realized that I did NOT have to waste 2 hours of my life taking apart and flushing the purge unit. All I would do in the future if this happens again is use a syringe with a hose attached (or maybe a straw with Windex so I could reach the purge unit) and drop some Windex on the purge unit ink pads and do a deep cleaning. Then repeat a few times until it is unclogged.
I am eager to see if anyone can prove my theory. I hope this helps someone from wasting 2 hours of their life! :)
In regard to the ink...in my industry it is not uncommon to have 2 different brand inks react with each other and create a clog. Its no problem if you stay with one ink brand...but when you switch back and forth you may be creating a problem. I would recommend that if you do switch over to a cheaper brand...make sure you do a lot of printing or maybe a few deep cleanings to purge out a lot of the old ink. Just don't change a cartridge and let it sit for 3 weeks. Thats what I did, and it caused a clog.
I checked inside the cartridge area for anything foreign. No luck. I unplugged and replugged the printer. No luck. Can you send me the photo and instructions that you have sent others?
Now I'm running into a bit of trouble. I managed to remove the ADF unit, scanner unit and entire top and side covers. However, I wasn't able to figure out how to remove the purge unit. I removed countless screws, loosening the print unit and the NCU board assemblies, etc. but the purge assembly remains firmly attached to the print unit. Moreover, a black claw-shaped piece of plastic hopped out of the machine while I was poking around the purge unit. Does anybody have a diagram or photos showing how to remove the purge assembly? Also, where does that claw piece go?
The other day I was getting the same error message and I slid the ink cartridge bar (or whatever it may be called) left and right (I did this a few times) and I put it back in its place and shut it and put it back on- it worked after this for 2 printouts but a few days went by and this has happened again. Nothing I do is working.
Is it perhaps a greater issue, and is it worth taking it to Canon for servicing?
Thanks for your help!
What are my options at this point?
I sent you an email with a pic of my purge assembly and wipers.
Should I be concerned? What if anything do I need to do?
Way back in 2008 you mentioned, "I also sell a complete Repair Manual for specific Canon, HP, and Epson printers. I don't have the MP530 yet but I do have the MP730, and the MP780, and the Service Manuals for the MP800, MP810, MP830, MP960."
I'm wondering if you now have a Repair Manual (which includes a circuit diagram) for a Canon MP530?
The the AC Adaptor in the MP530 has two small plugs connected to it: 1 x 2 pin, and 1 x 8 pin. When the Adaptor was being replaced with a new one, the wires that go to the 2-pin plug were broken. I need a circuit diagram to determine the polarity (if any) of the wires connected to the 2-pin plug - and of course, knowledge of how to get the printer apart to do the repairs!
If you do not have a MP530 Repair Manual available, could you please suggest a web-site from where I may obtain one? It is not available on-line, to the 'general public', from any Canon web-site.
Looking forward to your assistance.
The cartridge moved though the sequence, and comes to the middle when the printer is opened. But when trying to print from the computer it sounds ok for a little bit, then it makes a different sound, like it wants to move but doesn't and I get the 6A00 error.
I believe I need the detailed instructions on how to clean /fix this. I'll email as well. Thanks.
5C00 code - stopped all function - sat for 6 months - on inspection wiper was extended - spring stretched - pushed it back but it wont stay back - pads pop up fine. Any ideas?
I just took apart my MP530 which produces the 6A00 error, and cleand the wiping pads, rubber blades and everything I could reach from the purge unit. I also cleaned the print head.
The waste ink level in the EEPROM is 66%.
Though it helps, something still gets wrong. After cleaning, I can print a few pages, but then I get again the 6A00 error, and when I go back to the pads, they are full of ink again ; they even overfill, so that the rubber below the pads is also full of ink.
Can anyone give me an hint regarding what is going wrong ? Do you know which princip is used to get the ink from the cleaning pads to the waste ink absorber ? Even if the printer think the waste ink level is 66%, can the absorber be full though ?
Thanks in advance,
After cleaning the purge unit squeejee and the two absorbers with damp towels located at the right of the printer the problem was still there. The absorber carriage unit seem not to respond for the up and down motion it should be doing. I then decided to spray a little bit of wd 40 on the absorder carriage unit and a little bit on the squeejes. Voilà the printer return to its normal state. Try it before throwing it out. It may well be your solution Jean-Marie. Ciao
