I have an Acer ScanPrisa 620 UT. It works, but the RGB offsets are noticeable.
Other things which I noticed:
1. There seems to be some kind of calibration problem. I can reproduce the
problem mostly on grey-scale images with an area of about 50% grey value.
Some columns (1 pixel width) have darker grey values than the
immediate neighborhood.
2. If I look at a histogram of a scanned image it is noticeable that it has
"holes" for certain values, i.e. some rgb-values never get out of the scanner.
I would expect to get a continous histogram if I scan a photo (which I do get
if I use the scanner under windows).
