Seems like 8c51579..0655b05 have changed things a bit for 1133, I've spotted this behaviour now: - scanimage; scanimage // OK - xsane // preview stuck, power cycle - scanimage; scanimage // OK - xsane // preview stuck, read Rolf's cable replug notice, ok - scanimage; scanimage // OK again - xsane // now scan instead of preview -- worked! - xsane // preview stuck again > > 6140 also exhibited weird behaviour at 600dpi (the sound's also > > different from 75/150/300 which scanned just fine): the head > > might have been hitting the edge for a second or two with the > > result being gray bands along the scanning direction at the end > > of the file, I've uploaded a (8Kx5K) sample here just in case: > > http://fly.osdn.org.ua/~mike/tmp/sane-pixma/Canon-MF6140dn-xsane-600dpi.jpeg This holds; the scans are also strictly one-time, I've not been able to find a scanimage/xsane (both starting with preview or not) combos that wouldn't hang reliably until USB cable is replugged between libsane clients' invocations. > > 1133 didn't hit that (the 600dpi sound is also different) but the > > image quality suffers from some kind of a "cellular" effect, see > > http://fly.osdn.org.ua/~mike/tmp/sane-pixma/Canon-iR1133iF-xsane-600dpi.jpeg > > (300dpi and lower are fine though). This seems to have disappeared as of commit 0655b05.
