Hi All,
Now we have Matthias on board with his MX375.
Please don't use the old patches. I started changing code in pixma.c
where we might get problems with other scanners, e.g. with the
Imageclass sub-backend. So, we should find a fix which affects
pixma_mp150.c only.
We should start at the beginning. Please use attached patch with latest
code from git. I added some additional debug outputs to show the status
of adf scanning. Please create a debug file with 'export
SANE_DEBUG_PIXMA=4'.
I also added TODO comments as hints for possible fixes.
Cheers,
Rolf
