• Code: E540-8006
• Description: The tray 1 shift motor acceleration error
  The lock detection signal does not turn ON when the tray 1 shift motor has been driven for 1 second.
• Remedy: 1. The tray 1 shift area sensor PCB is faulty. 2. The wiring between the finisher controller PCB and tray 1 shift motor is faulty. 3. The tray up/down mechanism is faulty. 4. The tray 1 shift motor (M107) is faulty. 5. The finisher controller PCB is faulty.

• Code: E540-8007
• Description: The tray 1 shift motor error
  The lock detection signal does not turn OFF when the tray 1 shift motor is at a stop.
• Remedy: 1. The tray 1 shift area sensor PCB is faulty. 2. The wiring between the finisher controller PCB and tray 1 shift motor is faulty. 3. The tray up/down mechanism is faulty. 4. The tray 1 shift motor (M107) is faulty. 5. The finisher controller PCB is faulty.

• Code: E542-0001
• Description: Additional Tray Lift Motor timeout error
  Unable to complete the operation even after the specified period of time during initial rotation. When the Motor remains in the same area for the specified period of time and the same symptom occurs again after the first retry, it is detected as an error.
• Remedy: 1. Check if the Motor (M12) Connector is physically removed. 2. Check if the Motor failure occurs. 3. Check if the Additional Tray Clock Sensor (S23) Connector is physically removed. 4. Check if the Additional Tray Clock Sensor (S23) failure occurs.

• Code: E542-0002
• Description: Additional Tray Lift Motor clock error
  At initial rotation, when the Tray Lift Motor rotates and clock signal is not detected within the specified period of time, it is detected as an error if the same symptom occurs again after the first retry.
• Remedy: 1. Check if the Motor (M12) Connector is physically removed. 2. Check if the Motor failure occurs. 3. Check if the Additional Tray Clock Sensor (S23) Connector is physically removed. 4. Check if the Additional Tray Clock Sensor (S23) failure occurs.

• Code: E542-8001
• Description: Tray 1 time out error
  If the tray does not return to home position when the tray 1 shift motor is driven for 25 seconds. If the tray does not move to other area when tray 2 shift motor is driven for 5 seconds.
• Remedy: 1. The Tray 2 shift area sensor PCB is faulty. 2. The wiring between the finisher controller PCB and tray 2 shift motor is faulty. 3. The tray up/down mechanism is faulty. 4. The Tray 2 shift motor (M105) is faulty. 5. The finisher controller PCB is faulty.

• Code: E542-8002
• Description: Tray 2 shift area error
  The upper limit area is reached before the tray 2 paper surface sensor 1 detects the paper surface during paper surface detection operation. A discontinuous area is detected during tray operation. During evacuation operation, arrival at the area beyond the tray 2 paper surface sensor 2 is detected before this sensor detects paper surface.
• Remedy: 1. The tray 2 shift area sensor PCB is faulty. 2. The wiring between the finisher controller PCB and tray 2 shift motor is faulty. 3. The tray up/down mechanism is faulty. 4. The tray 2 shift motor (M105) is faulty. 5. The finisher controller PCB is faulty.

• Code: E542-8004
• Description: The tray 2 shift motor clock error
  The FG input cannot be detected when the tray 2 shift motor has been driven for 0.2 second.
• Remedy: 1. The Tray 2 shift area sensor PCB is faulty. 2. The wiring between the finisher controller PCB and tray 2 shift motor is faulty. 3. The tray up/down mechanism is faulty. 4. The Tray 2 shift motor (M105) is faulty. 5. The finisher controller PCB is faulty.
