Hi creekriot.

Were you able to install the updated drivers at this link: 

mac-mf-v10113-00.dmg

If so, have you tried completely uninstalling the drivers from Mac HD> Library > Printers >  Canon, and then reinstalling the drivers?

NOTE: Please restart the computer after deleting the files. When the computer is back on, empty the Trash before reinstalling the drivers.

If the issue persists, please call us at 1-800-OK-CANON (652-2666), Monday - Friday 10:00 a.m. to 6:30 p.m. ET (excluding holidays).
