I had the same issue on a fresh install of 16.04, after installing the brother drivers with their automatic script.
I ran an strace of simple-scan, as recommended by Kuwanger in the IRC, and found that simple-scan didn't have permission to access some cache files. The problem was that simple-scan's cache files were owned by root, and not accessible by the user. The solution was to run sudo chown -R <yourusername> ~/.cache/simple-scan Of course, replace <yourusername> with the name of your user. I hope that helps! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1376300 Title: Scanning works only as root after upgrade to 14.04 LTS, fixable by adding user to group lp To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/1376300/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
