Hello, from the logs I see you are running SANE 1.0.22. It would be nice if you could test on current git version. This can be done by downloading source code (see http://www.sane-project.org/snapshots/ ), unpack it, then run configure and make (you'll need libusb-devel), don't do make install, you can test as a normal user without installing by running this (in the backend directory): export SANE_DEBUG_GENESYS=255 export SANE_DEBUG_GENESYS_LOW=255 export SANE_DEBUG_GENESYS_GL124=255 export LD_PRELOAD=.libs/libsane-genesys.so genesys --clear-calibration --resolution 300 --mode Color 2>rl.log >rl.pnm Regards, Stef
