Looks like this takes a while without ready-made instructions, so I’ll jot ‘em down here for future reference.
- Pick up the Scan Tool zip archive from Epson’s site (not sure if the link works, but it’s in the support section. I picked Windows XP as my OS, the Linux option took me to a site which didn’t mention the 660 so I don’t know about that.
Euro/DATA/BIN/TAIL_061.BINfrom the archive.
- Toss the file into a suitable directory; I chose to create
/usr/local/share/sane/snapscanfor this purpose.
/etc/sane.d/snapscan.confand fix the firmware line to point to
TAIL_061.BINin wherever you put it in the previous point.
- Add your unprivileged self to the
scannergroup. Log out and back in to make it actual.
