The fact that you can reproduce this with the scanimage frontend means that the bug is not in gscan2pdf, but with the Canon backend.
Which package is providing the Canon backend? The possibilities are libsane directly, or a package provided by Canon. Either way, the following command from the CLI should demonstrate the problem to the maintainer: scanimage --device-name='pixma:04A91746_EABCEA' --mode='Color' --source='Flatbed' -y 297 -l 0 --resolution='150' -x 210 -t 0 --batch ** Package changed: gscan2pdf (Ubuntu) => sane-backends (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1067163 Title: Scan "all" not working for Canon Pixma MP280 series To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1067163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
