Hello,
beside log file, there are also other *.pnm files created during
calibration (in the working directory where the scanimage command is
ran). Can you send them ? What I suspect is that there could be some
color pattern (some kind of notch) in a area expected to be white. So
shading calibration is wrong and leads to the artifact on the scanned
picture.
Regards,
Stef
