hi,
I tried to do a duplex scan with a fujitsu fi-4120c
and USB interface ( the source code is 2004-08-24
version). It can not correctly scan with the duplex
mode of "both"(paper are half locked in the machine).
When set duplex mode to "back", it scan the same side
as mode "front".
I found an article at
http://lists.alioth.debian.org/pipermail/sane-devel/2004-April/010688.html,
but no more information about the solution. I find a
"[fujitsu] 5/38/0: Invalid field in parm list " in
the error log. what's mean?
Do the new version of the fujitsu backend solved this
problem? Where can I download the fixed version?
thanks!
Best Regards,
Qian
