You need to go farther than the lens glass. The dust is actually on the photo board itself. I'm assuming that the problem is on the bottom scanning side. You will need to dis assemble the scanner to remove the scanning unit. This can be done by remove the back, the sides, and the two front pieces. Once inside remove the silver metal cover over the rollers. This will help you get the actually scanning equipment out. Remove the black scanning unit behind the silver metal cover.

Make sure to ground yourself before continuing or you could short the boards.
Under the lens glass there are three boards. Two are visible. One is white, long and skinny. On the backside one is green. The one you need to get to is hidden between the black piece, and silver metal piece. There should be 6 screws that you will need to remove first.
Very gently pry the plastic from the metal. The problem that you are looking for is there.
Wipe the photo cells with an alcohol swab, and you should be good to go.

I've cleaned the glass and still have a black line on the image


Scan a document in 300 dpi in full width. Check where the line appears in the image. For example if the black line appears at vertical position say 1900, then it means the dirt is at 1900/300 i.e., 6.3 inches from left. Clean the area thoroughly. Check if any pin had created a scratch in the glass. At different contrast levels, if the line appears different, it is definitely unclean glass. On the contrary, if the line appears constant at various levels of contrast, then it is possible that scan module is faulty.

Getting vertical lines on scanned pages when duplex scanning on canon dr-3080c II scanner Only on duplex side of pages, though. Front page still shows up clean.


It is dust on the glass, clean it thoroughly. You will find it at the same location for all drawings and may get faded for lower brightness!

How do I clean the rollers on a canon DR-3080CII The paper seems to be slipping a little.


Lightly dampen a cloth with water or rubbing alcohol. Gently rub across the roller side-to-side, rotate a little, and continue until you've gone all the way around. The most important rollers are the 3 at the paper feeding area  (2 top & 1 bottom). The bottom roller will be harder to turn than the top 2. Just be gentle & patient to avoid tearing the rubber. Frequent light cleanings are better than waiting for problems to crop up.

I have a Canon DR-3080CII scanner that is making a lot of noise.


If you haven't had problems then they are probably fine. The feed rollers are rated for 500K pages, and usually last at least half that even under severe duty.  Regular light cleanings by the operator are recommended. Once a year a service tech should do a more thorough cleaning of the transport rollers & sensors. When the rollers do wear out, you can purchase them from online retailers like ScannerSolutions.com, but they aren't designed for easy user installation. Call your local dealer for a quote; the extra expense is worth the saved effort, and they should do a complete cleaning at the same time.
