[sane-devel] Canon MF4660 test/debug

[Nicolas Martin]

This Multifunction scanner should be candidate to be handled by the
pixma backend, where it is declared. 

In order to check what's going on, could you run scanimage as follows:

$ export SANE_DEBUG_PIXMA=10
$ scanimage -T

and send back the content of the console.
