Hello brave Linux community.
I have a CanoScan LiDE 200, which used to work seamlessly up to now, whenever I needed it (a couple of times per year).
Unfortunately the last time, although it is properly recognized and more-or-less working, it has a strange artifact. In the middle of the scanning area, there is a black bar only for bright colors (i.e. white or near-white).
This is not a fault of the scanner, since I tried it also once more under OSX and works perfectly.
To understand what is goung on, I have attached a linux scan as well as an osx scan to see the difference.
It might be related to this ancient question here, but the problem is that the scanner used to work up to recently.
Any ideas what is wrong?
