A totally different idea:
Your office12-scanimage.open.strace shows: --------------------------------------------------------------------------- open("/home/per/.sane/hewlett-packard-scanjet-2400c.cal",... --------------------------------------------------------------------------- this together with what "man sane-genesys" tells about calibration in particular things like --------------------------------------------------------------------------- If you plug the scanner in another machine or use it with another account, calibration will have to be redone. --------------------------------------------------------------------------- and --------------------------------------------------------------------------- --threshold percent 0..100% (in steps of 1). Select minimum brightness to get a white point. Pixels whith brightness below that value will be scanned as black. --------------------------------------------------------------------------- and how your office12-scanimage-scan10.pnm looks like:
Perhaps your current calibration is wrong?
Could you move /home/per/.sane/hewlett-packard-scanjet-2400c.cal away and test again and furthermore re-do the calibration and test again?
Okay, I did the following> power off/on scanner (to reset) rm ~/.sane/hewlett-packard-scanjet-2400c.cal scanimage --mode color --resolution 300 >scan001.pnm
weird colours. scanimage --mode color --resolution 150 >scan002.pnm weird colours. scanimage --mode color --resolution 300 >scan003.pnm weird colours.
I have never calibrated this scanner before, it was bought in June 2007, even if it came with a calibration sheet, it is long gone. Also, when I use it from office11 (openSUSE 13.1), it works fine. -- You are receiving this mail because: You are on the CC list for the bug.
