I checked on Sane supported drivers, and your device is well supported (pixma backend):
http://www.sane-project.org/sane-backends.html#S-PIXMA "i-SENSYS MF240 Series Flatbed and ADF scan. All resolutions supported (up to 600DPI, ADF up to 300DPI). 216mm image width buggy, restricted to 215mm." Please install xsane and check if you could reproduce this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759889 Title: Simple scan multiple page issue - Unable to read frame from device - Canon mf244dw To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1759889/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
