Hello!

If I scan with 1200 DPI with the ScanJet 4400c I get device IO error
every time after the scan started.

m@ryz:~$ scanimage --format png --output-file=test1200.png -d 'rts8891:libusb:001:006'  --resolution 1200 -v
scanimage: scanning image of size 10158x14078 pixels at 24 bits/pixel
scanimage: acquiring RGB frame
scanimage: min/max graylevel value = 0/214
scanimage: sane_read: Error during device I/O
m@ryz:~$ 

600 dpi (and others) don't produce that error.

Please tell me if you need further information.
