I'm looking for some advice from someone knowledgable about scanner hardware. If this isn't the place, I really hope someone can direct me to an appropriate forum.
Basically, I have two multifunction devices, both Canon MultiPass systems, a generation or two apart from each other. While they've been fine for me with all the printing, faxing, etc I've done, I recently noticed an issue while scanning photo prints. Specifically, I can see lines on the scanned images where very distinct small lines run across the image. They lines aren't white, they're simply lighter than the rest of the image in color. The lines are perfectly straight and thin. This effect shows much more easily on some images than others...sometimes I have to magnify on the screen to see them, sometimes they're very apparent (especially on dark prints). The strange thing is that it seems to occur on both MP scanner devices I own, even though they aren't even of the same generation of hardware. I'm considering buying a new scanner just for my photo prints, but if all scanners behave this way I certainly don't want to waste the money. I also can't afford to spend hundreds on a scanner. I'd really like to better understand what is causing the problem in order to figure out how to better address it.
Thanks.
