Code :

Code: 8B
Description: The paper feed motor stops suddenly.
Causes:
Remedy: Abnormal load applied to the paper feed roller PF-related gear(s) broken Replace the PF-related gear(s). PF encoder disk stained or scratched Replace the PF encoder disk. PF encoder sensor defective Replace the PF sensor PCB. Paper feed motor defective Replace the paper feed motor. Main PCB defective Replace the main PCB.

Code: 8C
Description: Current protection for the driver IC activated in paper feeding operation.
Causes: The driving current has exceeded the limit due to an abnormal load applied to the PF-related gears and rollers.
Remedy:

Code: 8D
Description: The paper feed motor rotates in the reverse direction.
Causes:
Remedy: PF encoder disk stained or scratched Replace the PF encoder disk. PF encoder disk dislocated Replace the PF encoder disk. PF encoder sensor defective Replace the PF sensor PCB. Abnormal load applied to the paper feed roller Check the PF roller gear and its related gears. Paper feed motor broken Replace the paper feed motor. Main PCB defective Replace the main PCB.

Code: 8E
Description: Max. speed error in the paper feed motor.
Causes:
Remedy: Abnormal load applied to the paper feed roller Check the PF roller gear and its related gears. PF encoder disk stained or scratched Replace the PF encoder disk. PF encoder sensor defective Replace the PF sensor PCB. Paper feed motor broken Replace the paper feed motor. Main PCB defective Replace the main PCB.

Code: A1
Description: Scanner cover (scanner unit) opened.
Causes:
Remedy: Scanner open sensor broken Replace the rubber keypad. Scanner open sensor actuator unhooked Set the scanner open sensor actuator into place. Control panel PCB defective Replace the control panel PCB.

Code: A2
Description: Document length exceeding the scan limitation. During scanning, 90 cm or longer of a document is detected. During document feeding or ejecting, 400 cm or longer of a document is detected.
Causes:
Remedy: Document jam Remove the jammed document. Document rear sensor actuator caught on the surrounding parts Correct the surrounding parts on which the actuator caught. Document rear sensor broken Replace the document rear sensor.

Code: A3
Description: The document rear sensor does not come ON during document pull-in operation.
Causes:
Remedy: Document jam Remove the jammed document. Document rear sensor actuator caught on the surrounding parts Correct the surrounding parts on which the actuator caught. Document rear sensor broken Replace the document rear sensor.
