This scanner is not in our list of supported scanners as far as I can
see. Which backend do you use? Could you send the output of
sane-find-scanner and scanimage -L on the server?

Which version of SANE is used on the server and which one on the
client (scanimage --version)?

The first problem is that saned sent a strange value to the net
backend. The net backend has detected that. This may be caused by a
crash on the server.

The second problem is that there seems to be a bug in the detection of
such problems which leeds to a segfault. Such a bug was fixed in
sane-backends 1.0.16 but without detailed logs I can't say if it's the
same problem.

We need more input. A full log on the client and server side may help.

Server:
Disable saned in (x)inetd.conf
export SANE_DEBUG_BACKEND=255 (use your backend name instead of "BACKEND")
saned -d128 (must be restarted after each call)

Client:
SANE_DEBUG_NET=255 scanimage -L

Bye,
