Description: MSU Output Error
Just after the machine was switched on, it could not detect that the MSU (Memory Super-charger Unit) was set.
Causes: • Replace the IPU.
Code: 392
Description: Development Bias Error
The development bias feedback voltage was less than 0.5 V for longer than 200 ms while the PWM duty value was more than 5% (indicating a development bias leak).
Causes: • Check the MCU connectors. • Check the harness on the MCU for damage. • Replace the high voltage cable. • Replace the CGB power pack.
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.
