     Hello,

     I haven't really work on color calibration. In order to improve it, 
would you run scanimage from the command line with the following 
environment variable set :

export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
export SANE_DEBUG_GENESYS_GL841=255
export SANE_DEBUG_GENESYS_GL843=255
export SANE_DEBUG_GENESYS_GL847=255
export SANE_DEBUG_GENESYS_GL124=255
scanimage -d genesys --clear-calibration --resolution 75 --mode Color 
 >scan.pnm 2>scan.log

     Then send me the various *.pnm files and the scan.log files. They 
will hold information that will allow me to tune the colors.

Regards,
     Stef
