I tried your command, it did not work the first time, the second time
returned a reasonable looking image.
$ scanimage -d genesys --resolution 100 --mode Color > scan100dpi.pnm
scanimage: sane_start: Error during device I/O
$ scanimage -d genesys --resolution 100 --mode Color >scan100dpi.pnm
# no output
The [image](http://img851.imageshack.us/img851/7334/scan100.jpg) looks
good to me.
When I tried to scan an A4 document, it worked on the third try. And the
scanner seemed slower to me. Additionally, it made some strange noises
that sounded like the head would move in two directions at once. The
error was the same “Error during device I/O”.
The image quality seems lower than the results that I got with Canon's
MP Navigator EX 2.0 on Mac OS X 10.5 before. I there used 200 DPI,
grayscale and textdocument as a source, writing a JPEG. Now I used
scanimage --mode Gray -x 210 -y 297 --resolution 200
and the [result](http://img708.imageshack.us/img708/8666/10543314.jpg)
does not look too good.
This is better than before, but the I/O errors are still strange. Is
there anything else, that I can do about that?
