Hope someone can help. I have a Umax 2100U flatbed scanner, which I use as a backup to my Lexmark all-in-one.
The problem is that whatever I scan, the resultant image has a broad (2" approx) multi-coloured watermark, running vertically down the right-hand side. Apart from that, the image quality is perfect. However, the strange thing is that if I select COPY rather than SCAN, the output to the printer produces a perfect reproduction of the copied document but that is of no use to me when I want to save to file, since copy to file is not available.
Mysteriously, after several attempts, with different documents, the problem seems to have disappeared. The only difference was that I selected advanced settings instead of beginner.
