Hp HP OfficeJet 6110

HP Officejet 6110 scan error

WHen turning on the printer an annoying (grininding) noice starts. After a bit, an error message is displayed (scan error). Printer has been used very little. Scanner enven less.
Called HP and they were not of much use (suggested taking it for service to Staple or CompUSA while they no longer service the "out of warranty"printers).
Any ideas
This post helped me with the same problem...amazing how cleaning a little cloudiness off of the underside of the glass affects how the scanner engine senses the start position!

There are essentially no scanner parts available for your printer from HP if you have an outright failure. I suggest cleaning the underside of the scanner glass. Also Lubricate the rod that the scanner head runs on. Use a few drops of Tri-Flow or sewing machine oil. You can get Tri-Flow at cycle shops in small squeeze bottles.

Thanks for the answer
Unfortunatelly problem is still not fixed despite the implementation of your suggestions.
HP support is just useless. Now they offer an "exchange at a discount".

My HP 6110 All In One also is showing Scanner Failure - which it did from the start but turning of and back on usually fixed it. The last coupe times it has been harder and harder to reset. It usually happens after I change the cartridge. I would like to know how may others have this problem. At this point I have been trying for a couple days to reset to no avail. Tried all the tricks in the book and also spoke to HP tech on line. But I too can have 15\% off a new HP - doesn't come with a free bottle of asprin so I think I will pass.

i am having the same issue with my 6110. I use it with a mac, tiger, and often have to push "copy" just so prints go through, otherwise nothing happens.

The clicking started a while back and happens on startup of the printer -

power-on - after the hum of the scan head - a few whines of the small scan head motor - a fast paced clicking happens, as if a cog is turning against another that is fixed.

Turning off and on and unplugging helps but it has been getting worse.

Today I opened it up and see that the scanner head on startup is moved forward a bit, then slowly returned back to the 0 point in short bursts - (the few whines of the small motor). Once it gets there to the end of the track the motor continues and the clicking starts. The head is not registering that it is at the end of the track. I could not locate any sensors or anything on the scan head. This seems like a software problem but I am not sure.

Any help would be fantastic.

I fixed the problem by reading this thread:

the glass underside just needed a cleaning near the scan head.

I Work for HP Tech support ..

WE DO OUR BEST TO HELP OUT AS MANY AS WE CAN ! BUT not all problems are fixable sometimes.. Just like when a car breaks down is it always a guarentee a car can be fixed ? ..

And the reason probably why HP wont take it back and offering you an exchange is because the unit is out of warranty ( hence u get 365 days of warranty time from the date of ur purchase)

The problem appears to be inhererrent with all the printers of this model. I was told by the authorised repair center that they have many of these and it costs more to repair than to buy a new one. Also appears that HP is hiding behind a warranty period of 365 days when this model printer is in fact a lemon. For the cost of this printer, you would expect it to last atleast 2-3 years.

Try gpoing to RUN....type "net stop spooler"...then type "net start spooler" That worked usually but the it happens again periodically

IT worked. had the same problem,
Step 1.Power off. Loosen 5 screws at top
2.Lift up about 30 degrees so you can see Rod scaner moves on
3.Used Spanjaard lubricating switch cleaner on right of rod.
4. Clean under glas on right hand side.
5.power up.

Thanks Sean - Worked like a charm!!
I busted one of the front clips holding the assembly down but it doesn't seem to make a difference (Unless I hold the printer upside down and shake it!!) - Anonymous
Hi guys.

I had exactly the same problem with my OfficeJet 6110 as reported above (i.e. the scan head not knowing where the end-stop is).

This is how to fix it (this method worked for me)

1) Lift up the scanner/copier hinged lid. Around the edge of the scan glass are 4 Torx screws. Undo all four screws.

2) Carefully prise the control panel faceplate off. The buttons underneath are on a single panel. Slide this to the left and lift off.

3) Jiggle the lid of the scanner to get it off the main body of the printer.

4) Locate the scan engine motor (top right corner) and remove the two motor retaining screws (one on the left of the motor, the other on the right).

5) Lift out the entire mechanism (rod, drive belt, scan head) and turn over.

6) Thoroughly clean all glass and mirrored areas of the scan head. Also clean the scan lamp on the top of the scan head. Clean the tray inside the scanner (where the scan head travels back and forth). Also clean the inside and outside of the scanner glass pane itself.

7) Refit all parts, using the technique described above, in reverse order.

8) Switch on printer. It should now work OK.

Hope this helps, guys.

I took the darn thing apart, cleaned it up and whacked the side really hard. Bam, it started working.

Thanks. - Anonymous

Just wanted to say thanks for your (old) post regarding the 6110 dismantling & cleaning. Had just ordered a new (Canon) printer because my HP failed, but now it is working just great and I can cancel the order for the new printer. Thanks!

Great Post Morganp104

Did what you said and fixed my problem

Thanks - unknown
How did you remove the mirrors from the scanner head so you can clean them? It looks like there are 4?

Thanks much

Your instructions were very thorough and helpful.

With step 3, I would suggest adding that there are two tabs on the front of the lid assembly. The tabs are attached to a release mechanism; pull the tabs up and toward you when facing the front of the unit.

The other suggestion is for step 4; it is not necessary to remove the T9 Torx screw associated with the scan motor. The two screws are both T10. - unknown
Morganp104 - Thank you your instructions - they totally worked. Just one small addition - when lifting the lid off in #3 - there are two tabs in the front which need to be pulled toward you to release.

Also, I cleaned the glass with blue window cleaner and it worked great.

Thanks again !!! - Anonymous

I have two of these printers, one working 100\% and the other with this scanner error. If I replace the main board in the faulty unit, all works. It is definately the main board that is faulty. I have also heard that this seems to be a common problem and sometimes intermittent which is definately caused by this board. My question: - is there a component on this board that can be replaced?

I have a 6110 that was making the grinding noise and giving the scanner error message. I fixed this one by finding what appears to be the scanner shipping lock under a black cover (one screw) on the left side of the scanner assembly and sliding the locking mech back into run position.

Now if I could just find the flimsy black clips that keep the top half from completely opening when one changes cartridges. HP does seem to want this model to go away as these clips aren't even listed on partsurfer.

I tried WD40 (which is generally not recommended on these types of electronics) on the rod on which the carriage moves and my HP Officejet 6110 works like a charm! - Anonymous
I too just fixed this exact same problem, but the original cleaning didn't fix the problem. The reason? I cleaned everything EXCEPT the part that was causing the problem. What part was causing the problem? The mirrors on the bottom side of the scanning device. There are two mirrors. One is flat across the bottom, and the other is tilted at an angle right next to the other mirror. Both of these mirrors need to be cleaned, as they were visibly dirty. This alone fixes the problem!!

I have the same problem (scanner bar does not know when to stop going to thr right when turning the printer on, and it starts making grinding noises). I took it all apart and cleaned the mirrors on the bottom of the scanner bar, but it did not help. does anyone have any other suggestions? Has anyone figured out how the printer is supposed to sense when to stop the scanner bar? It must be related to the mirrors as I see no mechanical switch or sensor. We did not use the printer for a couple months ans=d then when I moved it and plugged it in I am now getting th scan error when turning it on.

thank you. The steps worked. My printer is an older 6110, bought new about 6 yrs ago or so. Could not get the lid all the way off. Had to reach my hand into tight spot to remove scanner to clean mirrors. I did not remove motor.

Can you believe that today 9/25/07 I finally came across this thread after 3 years of frustration of not having my HP 6110 work? Just too damm busy in this crazy world and a laymen in the computer world. It is depressing to have a product go bad right after a few months of use, and then to have horrible service from HP techs who have the gaul to recommend we spend more money on HP products (pure greed), and finally to have no decency to say hey, we have enough defective printers, let's call them back or extend their warranties, which we pay for anyways. Thumbs down to HP but a thousand thumbs up to all of you in this thread, except the HP guy!

I have had the "scanner clicking" issue for sometime I talked to HP and this is what they told me:

1. Unplug the power supply from the wall outlet.
2. Unplug the power supply from the back of the printer.
3. Wait at least 20 seconds, then plug in the supply back into the wall outlet.
4. Plug in the power supply back into the printer.
5. Press the power button to turn the printer on

I followed the steps (skeptically) and it worked.

I too was skeptical about the glass cleaning. The scanner issue had been off and on for the last 8 mo. or so, and was getting worse by the event. Turning off and on usually worked after a while. This time, it wasn't working and I was fed up with it. I tried cleaning the glass from the inside, mailnly by the scanner head, and it worked. When removing the four screws and pulling off the keyboard face plate, you'll find tabs on the outer part of the glass lid facing towards you. Pull these tabs towards you and upward to disengage them. Once lifted, pull the entire glass & scanner lid upward. Do not attempt to lift as if there were hinges in the back. You should be able to turn the whole thing upside down to thoroughly clean the glass. Good Luck!!

We have had this prob for a while and I noticed it was heat sensitive. If the unit was turned off and then back on without cooling down, the prob would show, but if left off for an hour or so, all was well. Until we got to summer that is, then the issue was permanent.

Anyway, cleaning the glass both sides didn't help, so I also cleaned the mirrors under the scan head, as well as the small area of glass on the main scan window that normally rests up against the white strip under the plastic glass surround. One of these two things fixed the prob it seems.

HP need a swift kick up the butt for their attitude one this issue, but seems even the best manufacturers are taking this stance with products, we had an issue with a 1 year old kyocera printer and they told us we should just buy a new one.

Seems electronics companies really don't care about all this electronic gear going to landfill, so long as they keep selling equipment...

Your closing statement LT, unfortunately, is probably correct or HP thinks that the general public is a bunch of bozos and can't follow simple maintenance instructions. Scads of people that visit this forum have proven them wrong if we're basically considered to be bozos.

A good example of HP's cynicism or dishonesty is illustrated on one of their web pages that actually tells you how to remove the scanner glass of some models. I quote "This document shows how to clean the scanner glass internal surface of some HP All-in-One products. A dirty or blurry scanner glass may cause a deficient scanning and copy quality." It has been amply proven by posts on this forum that copy quality it not the major problem caused by a dirty scanner glass, but rather scanner failure. Their web page also says that following their own procedure will void the warranty and to avoid doing anything other than cleaning the glass. Tell me HP, what has the user got to lose by fiddling with other scanner parts if it isn't working and taking it apart voids the warranty anyway?

Now I can relax and solve some geopolitical problems.

There are actually 4 mirrors and a receiving lens inside the scan assembly. I found that my lens was filthy. You can remove the black cover of the scan assembly by inserting a small screwdriver through the 2 square holes in the top of the assembly, then clean the lens with a swab soaked in glass cleaner. Good luck!

My 6110xi prints great, copies great and faxes great. What it wont do is send scanned images to my computer. I keep getting an error. I tried uninstalling everything and reinstalling it but nothing seems to help. The only thing it wont do is scan to my computer. The scanner itself is working fine making copies and what not. I just don't know what to do.

Download and run the software cleanup utility and then reinstall the driver software.

If you have a high speed internet connection you may also want to download the latest driver.

I followed all the cleaning procedures.. Every reflective service, flipped over the scanner assembly.. Cleaned the glass.. I even cleaned the CCFL lookin thing.. Finally replaced the scanner, and all works fine..

Good Luck if you bought an HP.. Next time I'll stick to Epson. - unknown
Well, I guess I am not alone... Isn't there like a DIP switch setting or a key combo(like some copiers have a CROP code...Hold Copy, Repeat, Override(single sheet feed), and Print all at the same time to get to hidden menus.) Just need some way to disable the POST. I use it primarily as a printer anyhow.

This is my 3rd time cleaning under the glass. I have never had a problem in the past. This time around, I now have a "cover open- close document feeder cover". Does anyone know what this means and what I possibly did wrong in putting it back together? I have disassembled it and put it back together, but the same response. I have had this scanner/ printer/ fax for 6 years- I can't seem to part w/ it yet, despite the dirty glass every 2 years.

Ive tried everything but cant get the unit to get past the grinding noise. In the past the cleaning steps have helped. But now nothing works. 6+* while plugging in to reset the unit doesnt work. This problem has been intermittent for some time and seems to be less responsive with each issue. Next step is the garbage. Any different ideas to fix this nonsense?

You are all Genius'!!!!!!!!!!!!!!!!!!!

I had this once before and it stopped on it's own and then today, when I changed the cartridges, it happened again. I have had this for about 4 - 5 years and it has been a great little machine. I suppose that wear and tear will do funny things but I was about to follow the instructions by Morganp104 and I thought I'd just clean the glass first before I start unscrewing things. Bingo!!! I tried it and it is working. Busy printing as I type this. Thanks so much for the feedback and I don't know why I don't come to these forums first before I waste my time on the phone. Thanks all!!! :)

I had the same problem. Cleaned the scanner & the underside of the glass as described in this thread. Still had a problem with the screeching, grinding & then aborted print jobs. I then cleaned the metal rod on which the ink cartridges slide back & forth over. I applied WD-40 on a cloth & wiped down the entire metal rod. That has fixed my problem. Hope this helps.

Mine started perpetually trying to scan after several blips of power loss during an electical storm. Reading the threads about taking the thing apart sounded like a massive undertaking for a someone with little computer, or mechanical, expertise. I tried the suggestion about unplugging from power source, then unplugging the the power cord from the back of printer....waiting 20 seconds...then plugged in the main power source and then plugged the power back into the printer. worked!!! Thank you!

Scanner and Printing Problems.
My machine developed the grinding noise and carried out the glass and mirror cleaning exersise. I have also oiled the cartridge runner. Where the display once showed "scanner error. switch off then on again" I now get displayed "open door. clear cartridge jam and press enter" When I open up the the machine the cartridges do not move to the centre of its run so that I can reseat the cartridges. If I push enter the machine it is only good for reproducing on page of print before it displays the "open door etc" again . Also when photo copying the copy printing keeps off setting to the left hand as it goes down the page.
How do I sort out this problem

I looked for simple solutions before disassembing the printer. Fortunately, a simple one worked. Anon on 6/5/08 suggested cleaning the white strip on the underside of the lid. I did the same just now using the cloth intended for cleaning anti-reflective eyeglass lenses and a solution designed for the same purpose. I cleaned the white strip (its on the left side of the underside of the lid as you stand facing the front of the printer). Unbelievably, cleaning that strip stopped the scan error and the constant clicking noise. I'll bookmark this thread if problems crop up again. Thanks everyone!

For my printer the solution was also cleaning the white strip as suggested by Anonymous 6/5/08 and Mike in LA. Thank you.

I unscrewed the lid and removed the glass pane from the underside of the lid. Peeled the white strip carefully off the glass and cleaned it with a Q-tip and some Windex. I also cleaned the part of the glass where the strip was placed. Waited until it was all dry and reattached the white strip to the glass. Placed the glass pane on the lid again and reattached the lid. It fixed the problem!!! Thanks again.

Thanks everyone for all the tips..

morganp104, did you notice that the middle hinge on the scanner lid makes a full circle around the pin? It doesn't want to come off of the pin even with some prying with a flat head screwdriver. Anyone have a tip on how to remove the middle hinge so I can remove the upper portion of the scanner before removing the main glass?
