Description: Charge current leak Type: 2 - Description - The main control board notifies the SCU that the charge current from the high-voltage power pack does not reach the target due to such causes as a leak or power pack failure. - Detection Timing - When the charge current is applied
Causes: • High voltage power supply • Leak locations SP-Log: 7-402-3
Code: SC320
Description: Polygon motor abnormal Type: 2 - Description - The main control board notifies the SCU when the polygon motor driver does not reach a defined number of rotations within a predetermined period of time. - Detection Timing - When starting the preparation for writing
Causes: • Polygon motor SP-Log: 7-402-3
Code: SC322
Description: Laser synchronizing signal error Type: 5 - Description - The main control board notifies the SCU when image transfer is aborted and the image transfer buffer (FIFO) on the printer main board is full or in an error condition. - Detection Timing - During the image transfer process
Causes: • Laser synchronizing detector board • Main control board • LD control board SP-Log: 7-402-3
Code: SC323
Description: LD drive current over (LD error) Type: 2 - Description - The main control board notifies the SCU of LD overcurrent. - Detection Timing - During LD writing
Causes: • LD control board SP-Log: 7-402-3
Code: SC325
Description: Magnification correction error Type: 5 - Description - When the polygon motor is activated, a laser synchronizing detection output cannot be detected within a certain time between the laser synchronizing detector boards 1 and 2. The main control board notifies the SCU when the detection fails three times. - Detection Timing - At the activation of the polygon motor
Causes: • Laser synchronizing detector board • Main control board • LD control board SP-Log: 7-402-3
Code: SC341
Description: Development motor abnormal Type: 2 - Description - The main control board notifies the SCU when the development motor does not start up within a predetermined period of time or does not output the LOCK signal for more than a predetermined period of time during the rotation. - Detection Timing - During the rotation of the development motor
Causes: • Development motor • Main control board SP-Log: 7-402-3
