If you use AirSane's web interface and choose "PDF" as format, and "Feeder" as source, does the same problem occur?
You might try the latest version from git. It has been changed to improve behavior with Automatic Document Feeders.
Thanks for your answer. I just updated to the latest version from git. Actually I don't have an ADF, I was simply scanning multiple times. In the web interface, I have selected 'Platen', it's the only available input source. I could not reproduce the error in the web interface. But I could reproduce it again using the gnome scanner. I noticed, that just a part of the document gets compressed, see here malformed_airsaned_scan_v2.pdf I probably put the paper in the other way around. Do you think it could be a sane driver fault? Journalctl show this error multiple times while scanning:
io/hpmud/dot4.c 120: unexpected DOT4CreditRequest: cmd=4, hid=4, pid=4, maxcredit=65535
I just scanned again on the server using scanimage
and now the first page also was affected, but the following 5 weren't. Maybe this isn't AirSane related
Maybe this isn't AirSane related
No irregularities show up when testing AirSane with SANE's "test" backend, or my physical scanner, a Canon LiDE 60.
Okay thanks, then I am closing this for now.
When scanning multiple pages using gnome document scanner, the pages go vertically compressed. See this example pdf: malformed_airsane_scan.pdf
When scanning using
scanimage
from the server running AirSane, this does not happen and when running it from a remote device using airscan sane backend, it does happen, so if I understand it correctly it should be related to AirSane.AirSane is compiled from the latest master, commit
