• Remedy: 1. The aligning plate rear home position sensor (PI107) is faulty. 2. The wiring between the finisher controller PCB and aligning plate rear motor is faulty. 3. The rear aligning plate is faulty. 4. The rear aligning plate motor (M104) is faulty. 5. The finisher controller PCB is faulty.

• Code: E540-0001
• Description: Tray Lift Motor timeout error (Inner Finisher)
  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 (M11) Connector is physically removed. 2. Check if the Motor failure occurs. 3. Check if the Stack Tray Clock Sensor (S14) Connector is physically removed. 4. Check if the Stack Tray Clock Sensor (S14) failure occurs.

• Code: E540-0005
• Description: Tray Lift Motor clock error (Inner Finisher)
  At initial rotation, when the Tray Lift Motor rotates and clock input 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 (M11) Connector is physically removed. 2. Check if the Motor failure occurs. 3. Check if the Stack Tray Clock Sensor (S14) Connector is physically removed. 4. Check if the Stack Tray Clock Sensor (S14) failure occurs

• Code: E540-8001
• Description: Tray 1 time out error (Staple/Booklet Finisher)
  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 1 shift motor is driven for 5 seconds.
• 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: E540-8002
• Description: Tray 1 shift area error
  The dangerous area is reached before the tray 1 paper surface sensor detects paper surface during the paper surface detection operation. A discontinuous area is detected during tray operation.
• 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: E540-8003
• Description: Swing guide switch/Staple safety switch error
  The swing guide switch or staple safety switch is activated while the tray is operating.
• 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: E540-8004
• Description: The tray 1 shift motor clock error
  The FG input cannot be detected when the tray 1 shift motor has been driven for 0.2 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.
