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!
