Question about Canon CanoScan 5000F Flatbed Scanner
The glass plate seems to be "foggy" on the inside of the scanner. As a result, the pictures which are scanned are also "foggy." This is a relatively recent problem with the machine.
Is there any way of removing and cleaning the glass plate?
1st step. Remove the lid. It just pulls out at the hinge end by lifting straight up, horizontal if you like. Where the two lid posts insert in the scanner body you will find 2 screws, undo them, no need to remove at this point, too hard. Rememeber you left them in there though.
2nd step. Around the 4 buttons at the control end is a striped trim panel that is the full width of the scanner. Locate the join between this trim and the light grey underside of the scanner body and just left and right of the COPY & EMAIL buttons, Using your fingernails lift with some gentle force. This edge will pop up. Note, the trim panel has 3 location tabs that insert under the grey border edge around the glass. So pop the front edge first and pull towards yourself.
3rd step. Once this trim is removed you will note 4 little grey plugs equally spaced under this area. remove the plugs and you will find 4 screws. Unscrew them, no need to remove, remember point above.
4th step. Time for CAUTION. You will be able to lift the upper part of the scanner up in which the glass is mounted. ***There is a lead with little play connected to the 4 buttons PCB which is attached to the upper panel. To ensure you don't damage it accidently when cleaning the glass you can remove the 2 screws attaching it to the upper panel.
5th step. See if you can wipe it, with a VERY SOFT LINT FREE cloth, without putting you finger on it somewhere......................
6th step. reassembly is the same in reverse

According to the Canon USA website, this "fog" is deliberately applied as an antiglare coating by the manufacturer. The website says that even though it may look uneven and patchy, this is normal and it should not be removed. I had this same question some time ago and Canon tech support said the same thing.
The disassembly instructions were spot on, though. Thanks! I used them to try to fix a jammed scan bar.
