Thanks for the reply. I was able to get my scanner to work by following a different route.
1. Uninstalled and re-installed sane and sane-utils (not sure this step was necessary) 2. Downloaded and installed the drivers from the official Brother website (in order to use their brsaneconfig4 util) 3. Used brsaneconfig4 to configure the network scanner: sudo brsaneconfig4 -a name=BrotherScanner model=MFC-L8850CDW ip=<address> Just listing the steps in case someone else has the same problem. sane.service still shows inactive (dead), but apparently, as it was mentioned earlier, it gets activated on demand. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1577137 Title: saned.service masked and cannot be unmasked Status in sane-backends package in Ubuntu: Invalid Bug description: After upgrading to 16.04 (from 14.04) I noticed the sane daemon (sane- utils 1.0.25+git20150528-1ubuntu2) was no longer running.
