Question about Canon DR-3080CII Path-Through Flatbed Scanner
We are getting a line on any page that doesnt have writing, so it isnt deleting blank pages as it should be.....
Can you give me so tips on how to get rid of the line??
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 too followed the advice of Cdubyuh. Inside the lower reader unit it was filthy with the white paper dust. You have to be very careful in disassembling the reader unit because mine had a few glue spots. It took some very careful prying to get it to snap apart without flexing too much the circuit boards. The white circuit board is ceramic, not fiberglass so extra care was needed. I fixed a used scanner I bought (which was "no returns") and saved myself from a disappointing purchase with this advice.

The lower reading unit is damaged. On the canon 3080cII and 3080c this is a notorious problem. It can happen just after prolonged usage but usually happens more often because staples left in scan jobs fall into this part. You can replace the part in about 10 minutes and order it from http://www.copierpartsexpress.com/product_info.php?products_id=245099 for $488.12 plus shipping.... expensive...yes but better than buying another 3080cII for $2200-2800.
