Dell Photo All in One Printer 964-scan/copy problem

The toothed drive belt under the glass platen skips over the cog on the scanner/copier unit that tracks under the glass platen to scan the features of the targeted document. One hears a loud clicking sound as the teeth from the drive belt skip over the complementary teeth on the cog of the scanner/copier and no motion of the scanner/copier unit can be seen.

    Doesn't seem to be my problem...wish it was that easy though! We've had the machine for 15 months and it's worked fine until now.

    I have the same issue but cannot follow the posted instructions for getting under the glass to the belt area. I have removed all obvious screws that hold the white area to the black area that supports the belt mechanism. I popped loose two tabs under the front end; the front end now separates but it is still attached at the back. I cannot figure out what to do to detach the back and am reluctant to force anything. I don't understand the instructions about regarding "levering off control panel shrouds" there is nothing near the control panel that is still holding this; I need to loosen something at the back. Any help would be greatly appreciated!

I have exactly the same problem - has just suddenly occurred after 18 months of light use. I just posted my own problem before I saw yours.

Having got into the machine, If I move the carriage by turning the plastic cogs slowly with my finger, the problem doesn't occur. If I try and move the carriage with my hand, it does. I'm going to see if I can find a way of tensioning the belt bettet. There is a tensioning spring on the right hand side below the scanner carriage steel guide rod that runs from left to right at the rear of the scanner compartment. It may be that I can put a spacer at the end of the spring to increase spring tension.

By the way, to get into the machine, you have to do the following:
a) Undo all obvious screws on the top of the scanner
b) lever off the 3 black control panel shrouds with a small screw driver
c) Undo the 2 screws holding the control panel on - then get a slightly larger flat scew driver to lever this off. There is a flat cable that just pulls out of a connector block on the rear.
d) You should now be able to prize open the scanner - there is a recessed screw top left corner by some cables - be careful to remove this as well.

I'll let you know how I get on.

    I managed to fix this by adding a small steel washer to the right hand side of the belt tensioning spring - thereby increasing the tension in the spring. You need to lever the spring out first. It's much easier to ad the washer to the right hand end rather than the left hand end (and get the spring back again).

    Before re-assembling make sure the scanner guide rod is correctly seated - you will have lifted this away to get to the spring. Alsoensure that the scanner carriage is engaged with the toothed belt properly. Wind the scanner back to the left hand side using the plastic drive gear before re-assembly. If it still doesn't work, try adding a second washer. Make sure the hole in the washer is large enough to go over the nylon lug but small enough so that the spring doesn't work its way through.

This sounds like a problem I've had with a Lexmark scanner. It turned out that there was a switch on the bottom of the scanner that would lock the mechanism in place for shipping. Do you see anything similar on this unit, or am I barking up the wrong tree?

How do I dismantle the Scanner Unit (the box with the platen glass on top)?

Hello, my name is Steve.

Even if you are able to try to clean the Scanner (in this case it is not setup like a "full-size Copier, scanner" .

There are many very small wired plugs, ribbon cables the require to be removed from the logic board . The room of removal and re-install requires patients, as well as carefully unfastening the hidden snap clips.

I believe that the scanner head is the cause of the problem, unfortunately, there are no replacement parts. Call up Canon and see if it is under some warranty or is they offer a replacement of this model .

I hope this assists you, best regards,Steve

Getting a black vertical line on paper when using top feed, does not do it when placed on scanner


1. Check the Automatic Document Feeder for any debris (paper, lint, etc.)
2. Open the top cover to reveal the platen glass.
3. Look to the far left, you'll see a thin strip of platen glass seperate from the bigger plate where you place flatbed scans on.
4. Check the thin strip of platen glass for any marks (correction fluid, marker ink, etc.)
5. Wipe glass with a damp cloth and some Window cleaning detergant.

Does the line still appear now when you scan using the ADF?

Scanning a document from the ADF results in a line down the middle of each page scanned. Scanning from the platen (not using the ADF) works fine

Lift the scanner cover so that you can see the platen glass. Look to the left of the large sheet of glass and you will see a narrow strip of glass. This is the area used to scan documents fed from the ADF. Make sure that this glass is very clean. Use a damp cloth to clean any dirt or buildup.

The scanning feature doesn't work

Make sure once you have the software installed properly that you set up the file ( address) correctly. You need to have the designation specified.

Dell 1815 dn printer scanner issue: single line appears in scans

Do you get the same line when you use the adf for other purposes?

If so, check the scanner glass just before the platen for something like white-out on it. Clean both the scanner glass and platen glass with Windex.

That is a common problem on all ADF scanners.

Good Luck

White spots on scanned photos

There's probably nothing you can do for dust under the glass, but in the Advanced settings for your scanner, there is an option to turn on "Reduce Dust & Scratches", with three different 'strengths'. You may want to try this to see if it helps.
