Hello, I have an appendix to make – maybe someone has a hint for me, why the scanner behaves really strange:
Depending on the scanning resolution, the shifting on the color range is different! I used the following command to test this: scanimage --batch --source "ADF Duplex" --page-width 210 --page-height=297 -l 0 -t 0 -x 210 -y 297 --mode Color --resolution 300 Then I tried all available resolutions: 100, 150, 200, 240, 300, 400, 600. The results are strange: Scanning with 100,150,200 gives me: Blue -> Red Red -> Green Green -> Blue Scanning with 300 and 400 gives me: Blue -> Green Green -> Red Red -> Blue And scanning with 240 and 600 shows the RIGHT colors. How is that possible? And how can this problem be solved? I installed Rolf Bensch’s PPA (https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git), because it solved the back page cutting problem when scanning Duplex. (see http://permalink.gmane.org/gmane.comp.graphics.scanning.sane.devel/24903) Other than that, I only installed the Canon "DR-C125 Driver for Linux V1.0 (v1.0)". Any hint is appreciated! el-ti Am 04.03.2016 um 10:59 schrieb el-ti: > Dear Sane-developers and users, > > through this very helpful discussion > (http://permalink.gmane.org/gmane.comp.graphics.scanning.sane.devel/24903), > I managed to get my Canon Scanner working in Duplex without cutting 1 cm > of the back page. > > Everything seems to work fine.
