I managed to get it work just installing drivers (they gave couple errors though as I am running 16.04 and some newer softwares), installing scanner program from Ubuntu´s Applications and last editing following SANE file through terminal:
sudo gedit /etc/sane.d/epson.conf
And I did add there my printers static ip settings (autodiscovery in case that you use DHCP on your router):
net 192.168.2.2 (Check yours from the printer)
I had also epson2.conf file and you may want to edit that too if not working or just to be sure. Just add the same line(s).
"SANE (Scanner Access Now Easy) is the linux way of scanning. sane supports a great many scanners, and the community around SANE adds support for more scanners all the time. By and large, most supported scanners are plug and play simple (plug them in and your ready to scan). However, some scanners will require manual installation."
