• Code: SC701-02
• Description: Original pick-up motor driver error (1-pass ADF) Motor driver IC error flag was asserted when a jam occurred. Details: The protection mechanism of the motor driver IC detected overcurrent or overheat and output an error.
• Causes: Motor driver IC detected an error.
• Remedy: • Check the motor harness connection. • Check for torn paper on the paper path or foreign objects in the drive area. • Replace the motor harness. • Replace the motor. • Replace the board.

• Code: SC702-04
• Description: Protection device break error 4 (1-pass ADF) The non-interlock power supply system protection device broke the circuit with the 24V power supply on. Details: A motor defect or a short circuit occurred in either the pick-up motor, transmission stamp, or bottom plate lift motor and the non-interlock power system protection device broke the circuit.
• Causes: • Motor defect in non-interlock power supply system. • Harness broken
• Remedy: • Replace the pick-up motor, transmission stamp solenoid, or bottom plate lift motor. • Replace the harness of pick-up motor, transmission stamp solenoid, or bottom plate lift motor. • Replace the board.

• Code: SC702-05
• Description: Protection device break error 5 (1-pass ADF) The non-interlock power supply system protection device broke the circuit with the 24V power supply on. Details: A motor defect or a short circuit occurred in either the feed motor, pull-out motor, intermediate motor, scanning motor, or exit motor and the noninterlock power system protection device broke the circuit.
• Causes: • Motor defect in non-interlock power supply system. • Harness broken
• Remedy: • Replace the feed motor, pull-out motor, intermediate motor, scanning motor, or exit motor. • Replace the harness of feed motor, pull-out motor, intermediate motor, scanning motor, or exit motor. • Replace the board.

• Code: SC719-07
• Description: Downstream device communication error (D751) • Communication with the downstream device has established, but the device is not responding to the command sent out, even after being sent three times. • The port level of the downstream device does not become H level (break cancel) within specified time.
• Causes: • Interface cable (downstream device side) connector disconnected or broken • Board defective (Buffer pass unit or downstream device)
• Remedy: • Replace the interface cable between buffer pass unit and downstream device or reconnect the connectors. • Replace the board (of the buffer pass unit or downstream device).

• Code: SC719-08
• Description: Buffer pass unit_CTB_+24V_Power supply error Detected +24V power OFF of the Buffer pass unit PCB: CTB.
• Causes: • Buffer pass unit PSU defect • Connecter disconnected • Harness ground fault/broken • 24V load (motor/fan) layer short • PCB defective • Fuse tripped (PSU, PCB)
• Remedy: • Replace the Buffer pass unit PSU. • Reconnect the connector. • Replace the harness. • Replace the motor/fan. • Replace the PCB.

• Code: SC719-09
• Description: Buffer pass unit_CTB_+24VINT_Power supply error Detected +24VINT power OFF of the Buffer pass unit PCB: CTB.
• Causes: • Buffer pass unit PSU defect • Connecter disconnected • Harness ground fault/broken • 24V load (motor/fan) layer short • PCB defective • Fuse tripped (PSU, PCB) • PCB relay defect
• Remedy: • Replace the Buffer pass unit PSU. • Reconnect the connector. • Replace the harness. • Replace the motor/fan. • Replace the PCB.

• Code: SC720-01
• Description: Downstream device communication error (D703/D704) Communication with the downstream device has established, but the device is not responding to the command sent out, even after being sent three times.
• Causes: • Interface cable (downstream device side) connector disconnected or broken • PCB of downstream device defective • Controller PCB defective
• Remedy: • Replace the controller board. • Replace the PCB of downstream device. • Replace the interface cable.

• Code: SC720-03
• Description: Protection device break error 1 (D703/D704) Protection device break error (fuse tripped)
• Causes: • Short-circuit • Overload • Motor/solenoid defective
• Remedy: • Check the harness. • Replace the PCB/motor/solenoid.
