Hi Troels,<br>
<br>
I prepared a quick patch for your scanner in
'backend/pixma_imageclass.c'. The patch is based on recent
development version 1.0.25.<br>
<br>
You also need to copy the attached udev rules file to
'/etc/udev/rules.d'.<br>
<br>
I also added MF8500C Series. Both scanners should work with this
patch, if they are similar to running MF4700 Series.<br>
<br>
Please read README.linux for installing Sane and basic testing. <br>
<br>
If you want to see some debug messages in a terminal or if you want
to use ethernet, please read sane-pixma man page.<br>
<br>
Cheers,<br>
Rolf<br>
