I.e. when I try to scan a full page, whether I specify the full -x and -y or simply say scanimage, it only gets the first 16.5cm for the width and 22cm for the length rather than the full 21.5cm x 27.5cm (US letter size). In Windows it correctly scans the whole page though. It wouldn't take 3200 resolution, instead giving the message "scanimage: rounded value of resolution from 3200 to 2400" and then giving a "scanimage: sane_start: Error during device I/O" message. Unplugging and replugging the USB cable was required to do another scan after that. 2400 only gives the "scanimage: sane_start: Error during device I/O" message and it hangs for a while again. The next step down is 1200 which works fine, albeit slow. I haven't tried the transparency unit yet. The most critical issue thus seems to be that the driver doesn't copy the whole page. Is this something that's "easy to fix", is there any way I can help out? Thank you, Bjorn.
