Hi, I have exactly the same issue. I use Xubuntu 15.04 with a Canon Pixma MG5350 printer.
I added James Ring PPA and updated sane package, and this solved the issue. Please put the fix in official repository :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1512027 Title: open of device pixma:MX7600_... failed: invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1512027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
