Hello Hans,

Sorry to read none of the suggestions helped. I now recommend you look at deleting the Canon UFR2 from your Mac and then reinstalling it. If you open Finder you can delete the following folders and files. This information is from the Canon UFR2 v2.10 Mac User Guide.

Mac HD > Library > Printers > Canon > UFR2
Mac HD > Library > Launch Agents > jp.co.canon.UFR2.BG.plist
Mac HD > Library > Printers > PPDs > Contents > Resources > en.lproj > CNTD***Z*2*.ppd.gz

(where *** indicates the printer model and 2 indicates the language of driver used)

With all these files deleted and trash emptied, unplug the USB cable to the MF4370dn and restart the Mac. Then run the installer for the v2.10 driver and when it has completed, reconnect the MF4370dn USB cable and open System Preferences > Print & Fax to add the printer queue.
