• Code: 82
• Description: Recording paper jam in paper pull-in operation. (Although the registration sensor detects the paper, the paper width sensor fails to detect the leading edge of paper.)
• Causes:
• Remedy: Foreign materials in the paper path Remove foreign materials. Paper printed or paper with blackish leading edge fed Replace the paper with blank paper. Head flat cable connection failure Insert the head flat cables correctly. Paper width sensor defective Replace the carriage PCB ASSY. Main PCB defective Replace the main PCB.

• Code: 83
• Description: Recording paper jam. (The registration sensor detects paper abnormally early in paper feeding operation in the normal SF mode.) (The registration sensor sticks to ON in the highspeed feed mode.)
• Causes:
• Remedy: Paper double feeding caused by incorrect loading in the paper tray. Reload paper. Bank ASSY deformed. Replace the bank ASSY. Registration sensor actuator unhooked Set the registration sensor actuator into place. Main PCB defective Replace the main PCB. Registration sensor defective Replace the registration sensor PCB.

• Code: 84
• Description: Recording paper jam. (The registration sensor sticks to ON after completion of paper ejection operation.)
• Causes:
• Remedy: Foreign materials in the paper path Remove foreign materials. Registration sensor actuator caught on the surrounding parts Correct the surrounding parts on which the actuator caught. Registration sensor defective Replace the registration sensor PCB. PF timing belt come off Set the PF timing belt into place. The paper ejection roller does not rotate correctly Replace the engine unit. Main PCB defective Replace the main PCB.

• Code: 88
• Description: Recording paper jam. (Even after paper pulling-in operation, the registration sensor is still OFF.)
• Causes:
• Remedy: Jam clear cover not closed correctly Close the jam clear cover correctly. Registration sensor harness not connected correctly Correct the connection. Bank ASSY deformed Replace the bank ASSY. Paper pull-in rollers defective Replace the paper pull-in rollers. Mode switching lever (at the right end of CR guide rail) not sliding smoothly Clean the mode switching lever. At the ends of the paper feed roller shaft, any gear(s) damaged Replace the engine unit. Paper feed motor defective Main PCB defective Replace the main PCB.

• Code: 8A
• Description: The paper feed motor does not rotate.
• Causes:
• Remedy: Foreign materials in the machine Remove foreign materials. Paper feed motor harness not connected correctly Reconnect the paper feed motor harness. 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 engine unit. Paper feed motor defective Main PCB defective Replace the main PCB.

• 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 engine unit. Paper feed motor defective Main PCB defective Replace the main PCB.

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

• 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 PF encoder sensor defective Replace the engine unit. Paper feed motor defective Abnormal load applied to the paper feed roller Check the PF roller gear and its related gears. Main PCB defective Replace the main PCB.
