     Hello,

     scans of white areas with my LiDE 700F are OK. To rule out the 
problem may come from simplescan, could you run the appended script and 
check the sc300.pnm picture ? Copy it in an empty directory and run it 
from the command line so all the debug files will be in one place.
      If it is still affected by the problem, please send me the 
sc300.log file and all *.pnm files created during calibration so I can 
analyze what could be going on.

Regards,
     Stef
