There's a problem when you calibrate with command line. Once
calibration is
done, a scan is started. You have to put in a document so the scan can go on
so there is no error. To avoid this you have to add the -n or --dont-scan
option on the scanimage command line used:
scanimage -d genesys --calibrate --dont-scan
When default scanner settings aren't goo enough, it may not be able to
recognize the calibration target which must consist in a pure white sheet with
a full width horizontal black strip.
