[sane-devel] Canon MF8200C Series

[Rolf Bensch]

Hi Troels,

I prepared a quick patch for your scanner in
'backend/pixma_imageclass.c'. The patch is based on recent development
version 1.0.25.

You also need to copy the attached udev rules file to '/etc/udev/rules.d'.

I also added MF8500C Series. Both scanners should work with this patch,
if they are similar to running MF4700 Series.

Please read README.linux for installing Sane and basic testing.

If you want to see some debug messages in a terminal or if you want to
use ethernet, please read sane-pixma man page.

Cheers,
Rolf
