Simple Scan cannot find the Canon MF731C/733C multi-function printer/copier/scanner.
The same computer prints to the Canon MF731C/733C without issue.

If I make an entry in pixma.conf specific to the MF731C/733C, XSANE says it cannot read the MAC address and then that is cannot read the make and model.

avahi-discover can see the scanner including manufacturer and model when it does the _scanner._tcp scan.
