Question about Canon Pixma MP800 All-In-One InkJet Printer
During scanning, I now see white dots on the photos. I could see dust on the inner part of the glass. How do I clean the inner part of the glass? I am quite technical guy so hopefully someone could point me in the right direction.
Generally you should not have to clean the underside of the glass unless you are in a high dust environment. This would require disassembly of most of the printer itself. The glass is held in by double-sided tape or a bead of glue, so don't try to remove the glass sheet itself.
The easy part is the beginning, removing the scanner cover. Next you will have to locate screws around the outside and start taking panels off. Keep note of the panels and the screws. After the side panels are off, there should be a set of screws around the scanner itself that hold the scanner and plastic casing with the scanner glass. Once those are removed, the scanner glass with its frame should be able to be removed. From there you can use whatever you would like for glass cleaning, make sure it is streak free.
Older scanners make this easier. Most of them are 4-6 screws and the top half pops off and can be easily cleaned. A multifunction isn't so fun in this sense.
Hope this helps!

Tips for a great answer:
The inner side of the Document Cover (white sheet) (C) is easily damaged, so wipe it gently.
If the glass of the ADF (A) is stained with ink, correction fluid, or the like, black streaks may appear on the printed paper when the document is loaded in the ADF. With a clean, soft, lint-free cloth, wipe the glass of the ADF.
With a clean, soft, lint-free cloth, wipe the Platen Glass (D), the inner side of the Document Cover (white sheet) (C), the glass of the ADF (A), and the inner side of the ADF (white area) (B) gently. Make sure not to leave any residue, especially on the Platen Glass.
Cleaning the ADF Caution
Be sure to turn off the power and disconnect the power cord before cleaning the machine.
1. Open the Document Tray.
2. Open the Feeder Cover.
3. With a soft, clean, lint-free and dry cloth, wipe off any paper dust from the inside of the Feeder Cover (A).
4. After wiping, close the Feeder Cover by pushing it until it clicks into place.
5. Close the Document Tray.
6. Reconnect the power cord then turn on the machine.
