Wes, I'm going to need a more detailed log to figure this out. Also,
there is no point in doing a command line redirection when doing a
duplex scan, you will throw away the back page.
SANE_DEBUG_FUJITSU=35 scanimage --resolution 100 --mode grayscale
--source 'ADF Duplex' --compression JPEG --batch=out%d.jpg 2>
If that doesn't demonstrate the error, you could try changing to color
mode or increasing the resolution. I am trying to avoid that to keep
the log size small.
Then you will likely need to compress 5900a.log and send it to me
directly. If it is too big, you will need to use something like
dropbox to send it.
