I'm sorry about the issue. Please try the following fix:
1. Open the printer's front panel.2. Press the Clear/Back button. The printer's display should show: "REPLACE DRUM? 1. Yes 2. No"3. Ignore the display, but just press the 3 keys *00 on the keypad one at a time. (That is asterisk, zero, zero. Then it should show "Accepted" on the display.)4. Close the front panel. Then check printing.
Please reply at the box below. Thank you.
