1.
Log in as 'root'.
$ su
2.
Delete the printer's spooler registration.
Enter the following command:
# /usr/sbin/lpadmin -x [Printer Name]
Example: To delete the registration "CANON-iR105+":
/usr/sbin/lpadmin -x CANON-iR105+
3.
Uninstall the UFR II printer driver module.
For rpm packages:
Enter the following command:
# rpm -e cndrvcups-ufr2-x.xx-x
For deb packages:
Enter the following command:
# dpkg -P cndrvcups-ufr2
4.
Uninstall the common module for CUPS drivers.
For rpm packages:
Enter the following command:
# rpm -e cndrvcups-common-x.xx-x
For deb packages:
Enter the following command:

NOTE
This procedure describes the version of each module as "x.xx-x". When entering commands, insert the version of the driver you are using.
To check the version of the printer driver you are using, refer to "Checking the Driver Version" in the "Appendix".
If you are using Debian, uninstall using the "dpfg -P" command. You do not need to include the module version ("x.xx-x") in the command.
