ould you try to scan using USB first? The networking code uses the USB
code but adds a network stack to the USB interface. Therefore check
first if the device works over USB. If USB fails get the USB debug
information by setting SANE_DEBUG_PIXMA=11.
If USB works, but network scanning does not, please provide a debugfile
generated with SANE_DEBUG_BJNP=3. 
For details see man sane-pixma. If only netowrked scans fail, also check
the firewalling chapter in that man -page.

Kind regards, Louis
