I would be curious to see scanned photo of this issue.

I know there are kits available that contain new rollers.

What about scanning a picture that you have allready successfully scanned and making the two available for comparisons.

Have you cleaned more than just the glass? There is a process to follow cleaning other stuff in the scanner. I also cleaned my pictures with 99 percent alcohol. You tube video on cleaning the scanner may be helpful.

For starters I'd say don't long into Microsoft but create a local account.

For the love of humanity this needs to be reported to the proper authorities.

What are you talking about? Windows ISO?
