Description: Bar code number mismatch Type: 2 - Description - The SCU compares the bar code data read by the CCD and analyzed by the scanner IPU board with the machine identification number stored in the machine. If they do not match, the SCU determines that there is a bar code number mismatch. - Detection Timing - When the power switch is turned on
Causes: • SCU (System Control Unit) SP-Log: 7-402-1
Code: SC193
Description: IDU failure Type: 2 - Description - The IDU board diagnostics notify the scanner IPU board that it is faulty at power-on. Then the scanner IPU board notifies the SCU of this. - Detection Timing - When the power switch is turned on
Causes: • IDU SP-Log: 7-402-1
Code: SC196
Description: Extended IPU abnormal Type: 4 - Description - The extended IPU board diagnostics notify the scanner IPU board when its image processing ASIC on the extended IPU board is faulty at power-on. Then the scanner IPU board notifies the SCU of this. This check is not made if the extended IPU board is not installed. - Detection Timing - When the power switch is turned on
Causes: • Extended IPU SP-Log: 7-402-1
Code: SC197
Description: Extended IPU connection abnormal (A189 machine only) Type: 4 - Description - The SCU detects when the extended IPU is not connected. - Detection Timing - When the power switch is turned on
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
