The site you downloaded from is a bit confusing. It provides downloads
- Image Scan! for Linux (provides epkowa backend)
- Image Scan v3 (provides imagescan backend)
These aren't the same thing and both cater to different sets of
scanners. I would assume that Andrea's scanner is supported via Image
Scan! for Linux which includes a SANE epkowa backend. The Image Scan v3
bundle includes a SANE imagescan backend.

Quite a few distributions also implicitly include the snippets below
/etc/sane.d/dll.d/ as if they were part of /etc/sane.d/dll.conf. Both
Image Scan v3 and Utsushi install the configuration file snippets there,
IIRC. Not sure anymore about Image Scan! for Linux.

Please note that support for network attached devices with the imagescan
(or utsushi) backends relies on a non-free plugin. This is despite the
fact that Epsons's Software License Agreement makes you believe the
whole package/bundle is GPLv3.

Hope this helps,
