......... not sure why .........

but the post from Amsicora is coming up with a different heading, and I cannot reply to it:

Ansicora:

try this link

All-in-Ones (Multifunction Inkjet Printers) | AVASYS CORPORATION

it has Epson drivers; I wonder if you install this if they will drive your printer; (and scanner);

if you work on getting the printer going first;

if you try in a terminal

sane-find-scanner -q
that should find the scanner

then try

scanimage -L
if no joy on that, there is a permissions issue

(copy and paste the two commands, in sequence ...)
