Uninstalling the Driver

IMPORTANT
When you upgrade a driver, you can overwrite the old driver with a newer one. Uninstalling the driver is not required before the upgrade.
1.
Open [System Preferences] → click [Print & Fax], [Print & Scan], or [Printers & Scanners].
2.
Select all devices set from the driver you are deleting → click [-].
3.
Delete the folders and files for the driver you are deleting.
[System Volume]/Library/Printers/Canon/CUPS_MF_Printer
[System Volume]/Library/Printers/PPDs/Contents/Resources/CNPZB***ZB.ppd.gz
Where *** indicates a character string that represents the printer model.
IMPORTANT
If you delete a "ppd.gz" file other than that of the printer model you want to delete, the driver may not work correctly.
NOTE
If the [Authenticate] dialog box is displayed, enter the administrators name and password → click [OK].
4.
Restart your computer.
Uninstallation is complete.
