Robert Preston :

If the error is still there, perform a drum reset:


a. Open front cover.


b. Press the CLEAR/BACK on the control panel of the machine. The LCD will read "Replace Drum? 1. Yes 2. No".


c. Press 1. The LCD will display "Accepted".


NOTE: If you do not see the word “Accepted” on the display, perform step 8b and 8c again.


d. Wait for the machine to display Cover Is Open, Close the Front Cover.


e. Close the front cover making sure it latches on both sides.
