• Code: SC440-13
• Description: Image Transfer Power Pack Error (low output) (M). 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: SC440-14
• Description: Image Transfer Power Pack Error (low output) (Y). 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: SC442-00
• Description: ITB Lift Error Even though the ITB lift motor rotates, the ITB lift sensor failed to detect the specified sensor feeler status within specified time. Details: • During home-positioning (operation for fixing the separated status) (separation movement) The sensor failed to detect the transition from “feeler present” to “feeler absent” (separation movement) within 2000 msec from the start of ITB lift motor rotation. • During normal contact/separation movement (printing/process control/MUSIC/forced toner consumption) Contact movement: The sensor failed to detect the transition from “feeler absent” to “feeler present” (contact) within 2000 msec from the start of ITB lift motor rotation. Separation movement: The sensor failed to detect the transition from “feeler present” to “feeler absent” (separation) within 2000 msec from the start of ITB lift motor rotation. • During contact/separation movement under special conditions (paper jam, paper end etc.) Separation movement: The sensor failed to detect the transition from “feeler present” to “feeler absent” (separation) within 2000 msec from the start of ITB lift motor rotation. Detection timing: During contact/separation movement Detection interval: 2msec or more
• Causes: • Sensor smudged • Motor/sensor defective • Harness broken or problem with connection (such as a disconnected connector)
• Remedy: • If smudged: cleaning • If defective or broken: replacement • Problem with connection: reconnection

• Code: SC443-01
• Description: Image transfer roller end-of-life (K). Resistance level of the image transfer roller was "R+3" during image transfer voltage detection.
• Causes: • Image transfer roller resistance increased through time (Roller endof- life) • Connection fault between the image transfer power pack and the image transfer roller (High voltage harness broken, connector disconnected, or contact failure of image transfer roller bushes, etc.) • Image transfer power pack defective
• Remedy: • Replace the image transfer roller. • Reconnect or replace the high voltage harness or the unit. • Fix or replace the image transfer power pack.

• Code: SC443-02
• Description: Image transfer roller end-of-life (C). Resistance level of the image transfer roller was "R+3" during image transfer voltage detection.
• Causes: • Image transfer roller resistance increased through time (Roller endof- life) • Connection fault between the image transfer power pack and the image transfer roller (High voltage harness broken, connector disconnected, or contact failure of image transfer roller bushes, etc.) • Image transfer power pack defective
• Remedy: • Replace the image transfer roller. • Reconnect or replace the high voltage harness or the unit. • Fix or replace the image transfer power pack.

• Code: SC443-03
• Description: Image transfer roller end-of-life (M). Resistance level of the image transfer roller was "R+3" during image transfer voltage detection.

• Remedy: • Replace the image transfer roller. • Reconnect or replace the high voltage harness or the unit. • Fix or replace the image transfer power pack.

• Code: SC443-04
• Description: Image transfer roller end-of-life (Y). Resistance level of the image transfer roller was "R+3" during image transfer voltage detection.
• Causes: • Image transfer roller resistance increased through time (Roller endof- life) • Connection fault between the image transfer power pack and the image transfer roller (High voltage harness broken, connector disconnected, or contact failure of image transfer roller bushes, etc.) • Image transfer power pack defective
• Remedy: • Replace the image transfer roller. • Reconnect or replace the high voltage harness or the unit. • Fix or replace the image transfer power pack.

• Code: SC445-01
• Description: ITB unit control error: driven shaft FB Error detected by the TDCU. If a command sent from the TDCU indicates an error, the engine issues an SC. ASAP command: 0x58_0x40
• Causes: • ITB motor defective • ITB unit set error • Connector disconnected or harness broken • Driven shaft encoder sensor defective • Driven shaft encoder smudged or damaged
• Remedy: • Replace the ITB unit. • Replace the ITB motor. • Set the ITB unit again. • Replace the driven shaft encoder. • Reconnect the connectors • Replace the harness.
