The changes in the epson backend between 1.0.19 and 1.0.20 and between
1.0.20 and 1.0.21 are so trivial there is no reason that that backend no
longer works with either scanner mentioned below.
Of course, it doesn't get built with 1.0.21 so people are "stuck" with
the epson2 backend.

This bug is fairly annoying. It affects are growing number of Epson
scanners. Any idea when a fix will be forthcoming?
People could alternatively try the epkowa backend which comes with Image
Scan! for Linux. Available from:
Just make sure you pick the download menu that corresponds to your type
of device. Models for the Japanese market are available via:

The Epson Stylus CX3200 is not listed anywhere on our download pages but
if you select the CX3500 you should be fine. Note though that Image
Scan! for Linux has not been pushed through our testing program with the
CX3200. Also, we have not done any testing on MEPIS.

Are you sure the epson backend is included in SUSE's sane-backends
1.0.21 package? If so,

The latest upstream version for Image Scan! for Linux (iscan) is 2.25.0.
What version is SUSE's iscan-free?
You could give the latest upstream iscan packages a spin.

Which backend(s)? The epson backend, epson2 or both?

As Allen suggested, logs may be helpful answering that but I'd prefer
logs generated using the distribution's package over a git snapshot.
This ought to do the trick for the epson backend.

Just replace the backend names for epson2 and/or epkowa.
