Cartridge Error:
The new toner sensor could not detect the new toner cartridge correctly.
Error code 4F01
User Check:
• If the machine is on the uneven surface, place it on a level surface.

Solution:
  1. Connection failure of the relay front harness
    Reconnect the relay front harness.
  2. New toner actuator coming off or caught in some sections of the machine
    Reattach the new toner actuator.
  3. Develop joint coming off or caught in some sections of the machine
    Reattach the develop joint.
  4. New toner sensor failure Replace the relay front PCB ASSY.
  5. Paper feed drive gears failure Replace the main frame L ASSY.
  6. If the error display is not cleared after replacing the toner cartridge with a new one again, the main PCB is faulty.
    Replace the main PCB ASSY.
