with the adf fujitsu scanners, in grayscale or color, we get fine, lightly colored lines as a part of the scanned image, and the 'background' behind the document when the scan window exceeeds the size of the paper looks mottled gray, as reported on this list.
i can find no way in the interface manual to prevent this in hardware, though it has been reported that the same scanners under twain do not display these problems. hence, i assume that this can be corrected in software. are any of the existing sane backends doing this internally? i would like to do something similar as an option in the fujitsu backend... thanks, allan noah -- "so don't tell us it can't be done, putting down what you don't know. money isn't our god, integrity will free our souls" - Max Cavalera
