• Remedy: Disconnect and then connect J651 and J652 of the fixing motor. Replace the fixing motor. Replace the relay PCB. Replace the DC controller PCB.

• Code: E015-0000
• Description: The pickup motor rotation is faulty.
  The pickup motor has gone on, but the FG signal of the motor is not detected for 2 sec or more.
• Remedy: Disconnect and then connect J621 and J622 of the pickup motor. Replace the pickup motor. Replace the relay PCB. Replace the DC controller PCB.

• Code: E019-0000
• Description: The waste toner case is full.
  After the waste toner case has become full, 50,000 prints (A4) or more have been made without disposing of the waste toner.
• Remedy: Dispose of the waste toner. Check the operation of the waste toner bottle base. Disconnect and then connect J514 of the DC controller PCB. Replace the waste toner case full sensor. Replace the DC controller PCB.

• Code: E020-0001
• Description: The developing assembly is out of toner. The buffer motor rotation is faulty. The toner feed motor (sub hopper) rotation is faulty. After correcting the fault, be sure to reset the error. (COPIER>FUNCTION>CLEAR>ERR)
  The absence of toner inside the developing assembly is detected of 120 sec or more even when toner supply operation has been executed for the assembly.
• Remedy: Disconnect and then connect the connector (J504, J512) of the DC controller PCB. Replace the developing cylinder clutch (CL4). Replace the buffer motor (M18). Replace the magnet roller drive clutch (CL1).

• Code: E020-0002
• Description: The developing assembly is out of toner. The buffer motor rotation is faulty. The toner feed motor (sub hopper) rotation is faulty. After correcting the fault, be sure to reset the error. (COPIER>FUNCTION>CLEAR>ERR)
  The absence of toner in the buffer is detected for 60 sec even after toner supply operation for the buffer has been executed and when there is toner inside the hopper.
• Remedy: Disconnect and connect the connector (J504, J511) of the DC controller PCB. Replace the buffer motor (M18). Replace the following: magenta roller drive clutch (CL1), toner transport motor (sub hopper; M22), toner transport clutch (sub hopper; CL23), buffer inside toner sensor (TS1), buffer inside toner lower limit sensor (TS2).
