• Code: 400
• Description: ID Sensor Auto Adjustment Error
  Vsg did not get to 4±0.2 V when the ID sensor was adjusted automatically in the SP mode.
• Causes: • Clean the ID sensor. • Check the ID sensor harness and connector. • Replace the ID sensor. • Replace the MCU. • Replace the development unit. • Replace the CGB power pack.

• Code: 401
• Description: ID Sensor Vsg Error
  The Vsg level was detected lower than 2.5 V two times.
• Causes: • Clean the ID sensor. • Check the ID sensor harness and connector. • Replace the ID sensor. • Replace the MCU. • Replace the development unit. • Replace the CGB power pack.

• Code: 402
• Description: ID Sensor Vsp Error
  The Vsp level was detected at 0 V or more than 2.5 V for 2 consecutive copies.
• Causes: • Under the left upper cover, make sure that the hex screw of the main drive gear of the drum is tight. • Clean the ID sensor. • Check the ID sensor harness and connector. • Replace the ID sensor. • Replace the MCU. • Replace the development unit. • Replace the CGB power pack.

• Code: 440
• Description: Transfer Output Error
  A high voltage feedback voltage of less than 1.0 V was detected for 200 ms.
• Causes: • Check and replace the high voltage cable if necessary. • Replace the CGB power pack.

• Code: 460-1
• Description: DC Separation Corona Output Error
  A dc separation feedback voltage of less than 1.0 V was detected after more than 200 ms while the PWM duty value was more than 15%.
• Causes: • Check and replace the high voltage cable if necessary. • Replace the CGB power pack.

• Code: 508
• Description: Cutter Error
  The left and right cutter HP sensors stayed on or off more than 2 seconds.
• Causes: • Check the connections of the HP sensors on the left and right side. • Replace the HP sensors.

• Code: 520
• Description: Main Motor Error
  The lock signal goes LOW after the motor starts and gets to the set speed. If the main motor lock signal stayed HIGH for 5 seconds during motor operation, the motor stopped because of overloading.
• Causes: • Check that the motor drive path is not overloaded. • Replace the motor harness. • Replace the motor.

• Code: 521
• Description: Drum Motor Error
  The lock signal goes LOW after the motor starts and gets to the set speed. If the drum motor lock signal stayed HIGH for 5 seconds during motor operation, the motor stopped because of overloading.
• Causes: • Check that the motor drive path is not overloaded. • Replace the motor.
