A bit of clarification:
 
Canon released a packaged frontend+backend named scangearmp. This
program works fine as a whole, independently from SANE, with a few pixma
models only.

Among this package, there are some files named libsane-canon_mfp.* ,
which look like a closed source SANE backend. 
But as Daniel pointed out, never heard about any successful experience
in using these files with SANE. And I'm wondering whether they really
conform to the SANE standard ...
