SANE is the library that allows scanimage, scanadf, xsane, etc. to
talk to the scanner. If SANE isn't working, none of those work, i.e.
you can't get anything to work with the scanner.

Just because scanimage recognises the scanner doesn't mean that there
are no problems with it!

If you can scan properly with xsane, then SANE is evidently also OK.

It looks to me therefore as though scanimage has a problem talking to
your scanner. Please confirm this by trying the following at the
command line:

scanimage > image.pnm

If this scans properly, then please restart gscan2pdf with the --debug
option, try to scan, and post the output from the command line.

If scanimage doesn't scan properly from the command line try changing
the frontend in gscan2pdf in the Edit menu to scanadf. I've heard of a
couple of scanners that worked OK with scanadf but not with scanimage.
