GL841 based sheet-fed scanners (like your scanner) calibration has
been improved in SANE 1.0.23 . So you should upgrade SANE on your system
to get working calibration.
Regarding the Xerox travel scanner 150, if sane-find-scanner
reports it as genesys ASIC based, I can add support for it provided
someone send me one.
