Hmm, I finally had some time to look at this log, and the scanner is sending entirely black data. This might be a calibration problem, or it might be that the scanner does not support grayscale. Perhaps you could try a color scan? allan On Mon, Apr 20, 2015 at 8:12 PM, m. allan noah wrote: > hmm

Duplex & resolution appear to be interpreted, since the number of files and scanning speed varies, but the ouput is always a black image. Tried combinations of: scanimage --resolution {100,600} {,--mode Color} {,--source "ADF Duplex"} --batch Le lun. 6 avr. 2015 à 21:40, m. allan noah a écrit

I have attached a patch which will hopefully improve the situation. I have guessed at most of the parameters, and so we might have to experiment. Please apply this to a current git repo, and try some scans, simplex, duplex, color, gray, etc. allan On Wed, Apr 1, 2015 at 9:57 AM, Nicolas Marchildo

I went back and extracted the image data from your windows log. The image format from this machine is nothing like that from the DR-C125, and our attempt to descramble it using the same functions fails. Can you get another usb log from windows, but this time with a low resolution, color duplex scan

The log looks very similar to the DR-C125. Can you try building a current sane-backends git snapshot, and try the code? You might have to run as root user until we get the permissions sorted out. allan On Tue, Mar 31, 2015 at 9:31 AM, Nicolas Marchildon wrote: > After few attempts (reboot, locke

my scripts currently don't handle having this kind of mixed data in one log. I could update them I suppose, but it would be easier to get a smaller log- can you try bypassing the hub when making the log? Connect the scanner directly to the machine? allan On Mon, Mar 30, 2015 at 10:06 PM, Nicolas
