thanks for the answer
unfortunately the scanner is still not stable
I use this command:
scanimage -t 50 -l 80 -x 35 -y 5 -v -p --resolution=4800 --format=tiff >
it makes some noise, little movement than it stops forever
after ca 10 sec I do ctrl-c, it is saying " trying to stop scanner..."
than it scans the image, shows properly progress, save it, and stop the
head in the middle (doesnt park it)
if I do scanimage -L for example, than it parks head properly
it seems to me, may be there is a bug in the backend....
I see in the code there is en extensive debugging/logging facility -
could you give me some hints how to activate/use it? than I could share
with you the log
