I'm posting this to let you know of my progress with the Canon MF8230 (Mf8200 series):
Scanning from Simple Scan, XSane, Picasa works! In case of XSane it is especially sweet, since it only scans/enumerates devices once, (which for some reason takes ~20 sec on my box right now.) I'm still suffering from the phenomenen, that the scanner hangs in "Scanning ..." state after scanning has ended. Has anybody any ideas on why? I have therefore made two tcpdump's. One from scanning with sane and one from scanning with windows(in VirtualBox). My thought is that I eventually can track the differences in the traces, and find out what command the sane backend must send. Any pointers on tools or the like is most welcome. (Right now I have the hex dump from tcpdump) /Troels > > 2014-07-30 0:18 GMT+02:00 Troels Thomsen <troels.pil.thom...@gmail.com>: > > >> Thx Rolf >> >> -patch and scanner really works! >> >> I'm pulling code from git, and have followed the install guide, and am >> observing the following: >> >> - Scan --mode=grey/color works >> >> - Scan --resolution=600 works (and 75) >> >> - Buttons ... could not make it work >> >> - "scanimage -x 55 -y 55" works but "scanimage -x auto -y auto" does not >> >> - after scanning completes, the scanner is still printing "scanning ..." >> in the display, and can not print another page until it is forced out of >> this state (red 'clear' button, - are you sure? - yes) >> >> - There is a pause of 10 seconds before everything.
