Hi Rolf, I tested scanimage with different options today. In particular, I tested all the combinations of connection/resolution/color available with flatbed mode:
--Connection: usb/net --Resolution: 75/150/300/600/1200 --Color: color/gray/lineart ...for a total of 30 tests. I can confirm that all the combinations work, I have a folder with all the scans and a script, so I can replicate the operation while collecting debug info by setting SANE_DEBUG_PIXMA if necessary, and share all the results somewhere (eg. Google Drive). But ADF _do not_ work for me using scanimage or scanadf. Here's a sample output (SANE_DEBUG_PIXMA=3 PIXMA_EXPERIMENT=1): [pixma] pixma is compiled with pthread support.
