Well, the logs are partially usable, the first one fails probably before
the image data is sent from the scanner (Broken pipe), and the second
does just show only the very beginning of a scan sequence.
However, what is very curious, is that the first log shows the Pixma
dialect used here is different from all the ones implemented in the
But the first scanimage log you sent (which fails when image data is
about to be sent by scanner) uses the ImageClass Pixma dialect, so I
guess this model understands 2 different Pixma protocols ! Canon seems
to have reinvented the wheel again !
However, there's something we could try, as the MF8030 seems to
understand at least part of the ImageClass dialect:
The ImageClass file uses in fact 2 different ways to read image data, so
I've change a little bit the pixma_imageclass.c file to try an alternate
way. Could you try it, place the attached file in directory:
to replace the file already existing, recompile/reinstall, and take
another scanimage log as you sent in your first message.
