Welcome to Fixya
Error you provided means there is something wrong with the toner. Have you replaced the toners?
You may try this torubleshooting. Depress the Additional Function key, then the 2 & 8 keys at the
same time, and the additional function key again. This will display the service mode menu. Touch the Copier key. Across the top of the screen you should see " Function ". Touch it, look for CLEAR in the middle column. Touch it, then ERR, then
OK. Turn off the copier and wait a few seconds then turn it back on.
Thank you for using Fixya! If you need further help, reach me via phone at
