• Code: E592-0009
• Description: Upper limit error with Puncher Side Registration Sensor (LDR) (Puncher Unit-BE1/BF1/BG1/BH1). The light-receiving voltage (PTR3) was 2.5V or less despite increase in sensor light-emission (LED3).
• Remedy: 1. Failure of Puncher Side Registration Sensor (PCB3/ PCB4) 2. Failure of Puncher Driver PCB (PCB1). 3. Failure of Finisher Controller PCB.

• Code: E592-000A
• Description: Lower limit error with Puncher Side Registration Sensor (LDR) (Puncher Unit-BE1/BF1/BG1/BH1). The light-receiving voltage (PTR3) was 2.0V or more despite reduction in sensor light-emission (LED3).
• Remedy: 1. Failure of Puncher Side Registration Sensor (PCB3/ PCB4) 2. Failure of Puncher Driver PCB (PCB1). 3. Failure of Finisher Controller PCB.

• Code: E592-000B
• Description: Upper limit error with Puncher Side Registration Sensor (A3) (Puncher Unit-BE1/BF1/BG1/BH1). The light-receiving voltage (PTR4) was 2.5V or less despite increase in sensor light-emission (LED4).
• Remedy: 1. Failure of Puncher Side Registration Sensor (PCB3/ PCB4) 2. Failure of Puncher Driver PCB (PCB1). 3. Failure of Finisher Controller PCB.

• Code: E592-000C
• Description: Lower limit error with Puncher Side Registration Sensor (A3) (Puncher Unit-BE1/BF1/BG1/BH1). The light-receiving voltage (PTR4) was 2.0V or more despite reduction in sensor light-emission (LED4).
• Remedy: 1. Failure of Puncher Side Registration Sensor (PCB3/ PCB4) 2. Failure of Puncher Driver PCB (PCB1). 3. Failure of Finisher Controller PCB.

• Code: E592-8001
• Description: Trailing edge sensor error (External 2 Hole Puncher). The voltage of the light received is 2.5 V or less even when the light emitting duty of the trailing edge sensor (LED5, PTR5) has been increased to 66 % or more.
• Remedy: 1. The wiring between the LED PCB/photosensor PCB and punch controller PCB is faulty. 2. The LED PCB and photosensor PCB is faulty. 3. The punch controller PCB is faulty. 4. The finisher controller PCB is faulty.

• Code: E592-8002
• Description: Trailing edge sensor error (External 2 Hole Puncher). The voltage of the light received is 2.0 V or more even when the light emitting duty of the trailing edge sensor has been decreased to 0 %.
• Remedy: 1. The LED PCB/photosensor PCB is faulty. 2. The punch controller PCB is faulty. 3. The finisher controller PCB is faulty.

• Code: E592-8003
• Description: Horizontal registration sensor 1 error (External 2 Hole Puncher). The voltage of the light received is 2.5 V or less even when the light emitting duty of the horizontal registration sensor 1 (LED1, PTR1) has been increased to 66 % or more.
• Remedy: 1. The wiring between the LED PCB/photosensor PCB and punch controller PCB is faulty. 2. The LED PCB/photosensor PCB is faulty. 3. The punch controller PCB is faulty. 4. The finisher controller PCB is faulty.

• Code: E592-8004
• Description: Horizontal registration sensor 1 error (External 2 Hole Puncher). The voltage of the light received is 2.0 V or more even when the light emitting duty of the horizontal registration sensor 1 (LED1, PTR1) has been decreased to 0 %.
• Remedy: 1. The LED PCB/photosensor PCB is faulty. 2. The punch controller PCB is faulty. 3. The finisher controller PCB is faulty.
