A few questions first:
- Is the firewall opened correctly (see man sane-pixma)
- does this scanner even support the bjnp interface? Lately Canon is
excluding bjnp support from (certain?) new scanners:
check using avahi-discover and see if it repots something like:
Found service 'Canon MB5000 series-4' of type '_canon-bjnp1._tcp' in
domain 'local' on 2.0.
or
Browsing for services of type '_canon-bjnp1._tcp' in domain 'local' on
2.1 ...
Browsing for services of type '_canon-bjnp1._tcp' in domain 'local' on
2.0 ...
Do NOT specify the scanner in pixma.conf UNLESS it is in a different
ipv4 subnet (within one subnet it will auto-discvoer the scanner if it
supports bjnp)
