Scanner is leaving black strips on the sides of paper

replied on August 23, 2021

It can be hard to see things on the glass strip, best to just use a swab and rubbing alcohol to clean it really good. It should either be dirty glass or a problem with the light.

If there was something on the glass, wouldn't it be putting black strips along both sides of the paper it is scanning? It's only showing up on the back sides of the pages being scanned. The first side of the page looks fine. The back side of the same page has the black strip running all the way down the side of the paper.

The scanner should have a front scanner glass and a back scanner glass on opposite sides (top/bottom) of the scan path. If you are getting the issue only on the back page, then the glass you need to clean is the glass that the back side of the page passes in front of. Use a lot of elbow grease and clean the whole width and depth of the glass. Then when you think it is clean, clean it a bit more.
