Hi Johannes,
First try to scan using a USB connection, does that work? It is
essential that the scanner works over USB.

And second, try WITHOUT mentioning the scanner in pxima.conf:
export set SANE_DEBUG_BJNP=4 
scanimage -L 2>log

and check if you get any response from the scanner in the log file.

And by the way: did you open the firewall (see man sane-pixma)
So far most Canons do support bjnp, but I learned of one type (forgot
which one) that does not support it.
If there is a bjnp response and the device works on USB, we can discuss
how to debug the issue.

best regards, Louis
