You are using the standard epson backend that comes with sane and not
the epson kowa backend made by Epson?
Which version of SANE do you use on the server?

What error happens? Please show us the complete output in syslog that
was generated by saned. Example:
Jan 7 11:43:06 hmg1 saned: connect from hmg1
Jan 7 11:43:06 hmg1 saned: saned from sane-backends 1.0.9-cvs ready
Jan 7 11:43:06 hmg1 saned: check_host: access by remote host: 127.0.0.1
Jan 7 11:43:06 hmg1 saned: init: access by firstname.lastname@example.org accepted
Jan 7 11:43:23 hmg1 saned: quit: exiting
Does the error also happens if you use the test backend? e.g.

The implementation of the cancel function in SANE can be tricky and
the net backend sometimes shows bugs that aren't apperent without it.
But it's hard to tell the cause when the problem can't be reproduced.
So I guess it's up to the backend maintainer to find out what's wrong
here, if he can reproduce :-)
I tried with my (non-Epson) scanners and can cancel scans without
