[sane-devel] How can I help with Canon Maxify MB2000 series testing?

[Patrick Roncagliolo]

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.

Seems that pages in the ADF are not recognised: see "ADF page count=0".
