Question about HP Photosmart 3310 Printer

Cleaning scanner glass

I have a HP 3310 all-in-one printer scanner. The glass is very dusty underneath and I would like to clean it to improve the quality of photos I am scanning. There isn't any information via HP on how to clean the underside of the glass. I have removed two screws from the front left and front right of the scanner but there is something holding the 'frame' in place at the back. Some online help sites say to press clips (on other scannners) but I don't see anything obvious here. Has anyone managed to accomplish this?

    I have the same problem, and when I chatted on line with HP they said to take it to a service center near me and asked for my zip code and gave me the address to the nearest service center, which I will take today to be cleaned.

    I need to be able to take my glass out of my HP OfficeJet 7310 xi, but am unable to find any information from HP. I do not wish to take it to an authorized dealer as I normally have the skill to perform this myself. However, I am unable to get the ADF lid to come apart as well as the control panel. Once I am able to do that, I will be fine. Should something break, the warrantee is expired anyway, not such a great loss. Any type of schematic would be best but I can live with a step-by-step solution. Thanks.

    Cleaning scanner glass HP PS 3110, 3310, C7180

    The solution is valid for my 3110 and C7180 as well. The screws are torx #10 . On the hinge lugs I clipped off the locking projections from the lugs to make the lid easier to remove. I do this sometimes when the scanned item is large.

This solution is for the HP 3310 all-in-one.
How to clean under the glass.
1. Find the small wire that runs from the lid to a jack on the back and disconnect it, un-clip the wire from the holders and let it hang free.
2. Lift the lid and pull it straight up about 3/4 of an inch, you will see two indents in the hinge, push these one at a time to release the lid. Remove it completely.
3. 3 screws are located under the hinge, remove them as well as the two in the front.
4. In the back, gently pull on the silver end pieces to release the top from the unit.
5. You can now turn it over to clean the glass.
6. to reinstall reverse the steps and remember to plug the jack back in.
That's it, easy when you know how. Pay HP service nothing!

    Thanks LaziMon for your input. I had the HP 750xi . Followed your instruction with a little modification and I was able to get into my bottom glass. I raised the top lip all the way up and when it was at a 90% just pulled top cover straight up and out. The slots where the lid came out there are two torx screws left and right side I used the black handle torx screw and remove both screws. Lifted cover gently about 3/4 inch. On the front of the unit I pulled gently out and up. and the hold cover came up. BE CAREFULL AT THIS POINT BECAUSE YOU HAVE ELECTRCAL TAPE THAT YOU DON' T WANT TO DAMAGE. GOOD LUCK

1Step One Gather your cleaning materials. You'll need a soft, lint-free cloth (anti-static rags are particularly good for this purpose); and Endust for Electronics, an eyeglass cleaner, or a mild, non-streak glass cleaner. 2Step Two Check your owner's manual. If the manufacturer has provided specific instructions, follow them. 3Step Three Unplug the scanner. 4Step Four Spray glass cleaner on your cloth. 5Step Five Raise or remove the scanner lid. 6Step Six Wipe glass until visible dust specks and grease have been removed. 7Step Seven Immediately wipe the screen dry with a dry portion of the rag or a second rag. 8Step Eight If you are not satisfied with the results, repeat the process. 9Step Nine Clean the chassis with the same fluid or with any other product suitable for cleaning plastic. (Some manufacturers recommend mild detergent dissolved in water.) 10Step Ten Clean under the glass (the underside of the glass and inside of the chassis) only if recommended by the manufacturer. Some manufacturers recommend carefully cleaning the mirror with a camel-hair brush or compressed air; most manufacturers recommend professional service for interior cleaning. Tips & Warnings good luck

Ihave a hp all in one printer scanner and copier, there is dust under side of glass how do I clean it the model is b110, been like it from new don't seem to be able to get hold off hp

HP says below that for your printer it can't be cleaned except by an authorized dealer. I know from experience that flat bed scanners/all-in-one's have small holes in and around the tray that houses the scanner assembly. If you take canned air and use the long straw that comes with it, you can usually do a fairly decent job cleaning the underside of the glass. It won't necessarily be perfect, but I've found that it's better than what I had before.

You may be able to find several spots to feed the straw through to blow air at the glass.

PLEASE....DO NOT TURN THE CAN UPSIDE DOWN AND SPRAY. You'll inject liquid into the scanner assembly tray and onto the glass. Have someone help you turn the printer upside down or on it's side if you need to get the angle to spray.


Flatbed products have a large scanner glass under the top cover.
The underneath side of the scanner glass cannot be cleaned on any product. This is unlikely to be necessary and should only be done by an authorized service provider.

How do I clean the mirrors on the HP 7680 All In One so that the scanned photos do not look dusty?

More than likely on that model, the mirrors as you call it will not get dirty it is sealed.If the glass appears foggy, that does not affect the quality of you scans generally.Alot of the newer scanners create that on the glass.And frequently the new replacemtn scanners have that too.

Yes you can. Just be careful not to force any movement of the scanner lamp. Be gentle. Otherwise you have nothing to fear.

Clean glass on MP830?

Best left alone this one, even printer technicians dont remove glass on the scanner unit they just replace the whole scanner assembly, the reason? there are a lot of plastic clips holding it together and springs and cables that are easily dislodged,

often the improvement in scan quality isn't as great as one would think.
the scanner assembly can be replaced as a unit for around $200

Solution: I found a very small piece of paper between the glass and the scanner housing. The lamp's seen that and sent the error message. Nobody find that little stucked paper and the "IT expert" sad: need to buy a new machine because he can't repair it. So, sometimes the solution is very easy just need some attention. :)
