For a couple of days I have been trying to get Scan to PC and/or Scan to PC GUI to work with SCX-3185FN. I have tried under Xubuntu 16.04 (64-bit), and - since it did not work - alternatively under Ubuntu 14.04 (i386).
Basically the scanner gets recognised (e. g. under Xsane, also under scanimage - L and netdiscovery), but - according to log - after the service recognises the device, it ends with some error, and on scanner I always get "not available".
I tried experimenting with several different versions of drivers (3.x, 4.x, 1.x...), but it did not resolve the issue. I also tried changing config files, as described under Scanning Questions (such as setting tcp address in .conf files). I also completely disabled the firewall.
I have a couple of question:
1. Under which Ubuntu (Xubuntu) version is Scan to PC working, preferably with my scanner model?
2. Does the Samsung driver has its support of Scan to PC?
3. Is it enough to select Scan to PC (and/or GUI version) from Synaptic with its (default) dependencies, or do I need to install some extra packages?
4. What else could I try?
If you want, I will attach my logs as well.
