The i-sensys MF633c is mentioned as requiring 3.70 and the model of your printer is so close it's probably the saem family as that one .
It's weird, but many things about canon printers on non-supported linuxes are weird.

Canon also supports this driver on i686 and MIPS64 .
IF
you run archlinux (or something close to it) on such a processor
AND have a supported printer
AND are willing to help test necessary adjustments
THEN please send me an email.

The printers supported by this package are often networked.
problems can be in the cnrdrvcups-lb driver, but also with authentication over smb, vpn settings etc .
Troubleshooting those is often very hard.
Archlinux and derivatives are not supported by canon. Use whatever works for you, even if that means using canon drivers in a VM that runs a supported distro .
