• Code: SC421-03
• Description: OPC home position signal detection error (M). Failed to detect the home position signal within specified time.
• Causes: • Home position sensor defective/Loose connection/Harness broken/Connecter disconnected • Home position sensor smudged
• Remedy: • Check the home position sensor connector. • Check the home position sensor harness. • Replace the home position sensor if it is found to be defective. • Check the sensor for smudges. Blow it with air and check again.

• Code: SC421-04
• Description: OPC home position signal detection error (Y). Failed to detect the home position signal within specified time.
• Causes: • Home position sensor defective/Loose connection/Harness broken/Connecter disconnected • Home position sensor smudged
• Remedy: • Check the home position sensor connector. • Check the home position sensor harness. • Replace the home position sensor if it is found to be defective. • Check the sensor for smudges. Blow it with air and check again.

• Code: SC440-01
• Description: Image Transfer Power Pack Voltage Leak (K). An interrupt checks the status of the power pack every 10 ms. This SC is issued if a problem exists with 50 consecutive samplings (500 ms). Details: SC issued when the image transfer power pack output current is leaking. The IOB checks for SC signals as described above.
• Causes: • Image transfer power pack output current is leaking.
• Remedy: Remove the high voltage cable from the output terminal of the image transfer power pack and check the following items. • PWM signal check If signal is fixed during image transfer, replace the cable or the IOB. • Image transfer power pack output check If output is fixed during image transfer, replace the power pack. If output is normal during image transfer, replace the high voltage cable, ITB or the transfer roller.

• Code: SC440-02
• Description: Image Transfer Power Pack Voltage Leak (C). An interrupt checks the status of the power pack every 10 ms. This SC is issued if a problem exists with 50 consecutive samplings (500 ms).

• Causes: • Image transfer power pack output current is leaking.
• Remedy: Remove the high voltage cable from the output terminal of the image transfer power pack and check the following items. • PWM signal check If signal is fixed during image transfer, replace the cable or the IOB. • Image transfer power pack output check If output is fixed during image transfer, replace the power pack. If output is normal during image transfer, replace the high voltage cable, ITB or the transfer roller.

• Code: SC440-11
• Description: Image Transfer Power Pack Error (low output) (K). The transfer roller resistance level was "R-3" (detected voltage was lower than 0.1kV).
• Causes: • Image transfer power pack defective • Problem with input harness to the image transfer power pack (loose connection, harness broken, or connector disconnected).
• Remedy: • Fix or replace the image transfer power pack. • Check the input harness and connector of the image transfer power pack.

• Code: SC440-12
• Description: Image Transfer Power Pack Error (low output) (C). The transfer roller resistance level was "R-3" (detected voltage was lower than 0.1kV).
• Causes: • Image transfer power pack defective • Problem with input harness to the image transfer power pack (loose connection, harness broken, or connector disconnected).
• Remedy: • Fix or replace the image transfer power pack. • Check the input harness and connector of the image transfer power pack.
