Hello, i have bought a new Canon LiDE 20. I have me decide for these Scanner, because these is list on the website from the sane-project with status "complete". Also have another LiDE 20 user from the ELUG(Essener Linux User Group) send me demo-scans. These scans have also a good quality.
Yesterday, i have install the Scanner on Debian etch(testing) with follow sane version: $ scanimage --version scanimage (sane-backends) 1.0.15; backend version 1.0.15 The Scanner runs also, only the quality is under Linux bad. The pictures have dark vertical lines through the scans. :-( I have make test scans, that you can see these vertical lines. Please follow the links to the testscans below. The lines are not on the glass plate of the scanner and not on the original photos. Yesterday, i have try adjust the settings in xsane. These adjust was of no avail. :-( Now, i have these scanner install on windows. There are no vertical lines in the scans. See the links to my testscans below. I have yesterday also tested the latest snapshot of sane-backends. With these, there was the same dark vertical lines. How can I remove the dark vertical lines in the scans on linux? Why are these lines not at the demo-scans of the other LiDE 20 user from the ELUG on Linux? Where do the dark vertical lines come from and why are they not on windows?
