Code :

Code: C40A1
Description: Mechanical controller sub-CPU communication error. A CPU communication error is detected.
Causes: MFP board (MFPB)
Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace MFPB.

Code: C40A2
Description: Mechanical controller PF communication data error. A CPU communication error is detected.
Causes: MFP board (MFPB)
Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace MFPB.

Code: C40A3
Description: Mechanical controller PF transmission timeout. A CPU communication error is detected.
Causes: MFP board (MFPB)
Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace MFPB.

Code: C40A4
Description: Mechanical controller PF communication pulse error. A CPU communication error is detected.
Causes: MFP board (MFPB)
Remedy: 1. Turn OFF the main power switch, disconnect and then connect the power cord. Wait for 10 sec. or more after connect the power cord, and turn ON the main power switch. 2. Rewrite the firmware. 3. Replace MFPB.

Code: C4101
Description: Polygon motor rotation trouble. • The polygon motor fails to turn stably even after the lapse of a given period of time after activating and changing rotation speed the polygon motor. • Motor lock signal detects HIGH for a given period time consecutively during the polygon motor is rotating.
Causes: • PH unit • MFP board (MFPB)
Remedy: 1. Check the connector between the PH unit-MFPB CN18 for proper connection and correct as necessary. 2. Replace the PH unit. 3. MFPB F15E conduction check 4. Replace MFPB.

Code: C4501
Description: Laser malfunction. • SOS signal is not detected even after the lapse of a given period of time after starting the laser output. • SOS signal is not detected for a given period of time during printing.
Causes: • PH unit • MFP board (MFPB)
Remedy: 1. Check the connector between the PH unit-MFPB CN18 for proper connection and correct as necessary. 2. Replace the PH unit. 3. Replace MFPB.

Code: C5102
Description: Transport motor failure to turn. The motor lock signal remains HIGH for a predetermined continuous period of time while the motor is turning.
Causes: • Transport motor (M1) • MFP board (MFPB)
Remedy: 1. Check the connector between M1-MFPB CN19E for proper connection and correct as necessary. 2. Check the loading status of the transfer roller drive, and correct the error as necessary. 3. M1 operation check • Control signal: MFPB CN19E-3 to 7 • Location of electrical component: 26-C 4. Replace M1. 5. MFPB F10E conduction check 6. Replace MFPB.

Code: C5103
Description: Transport motor turning at abnormal timing. The motor lock signal remains LOW for a predetermined continuous period of time while the motor remains stationary.
Causes: • Transport motor (M1) • MFP board (MFPB)
Remedy: 1. Check the connector between M1-MFPB CN19E for proper connection and correct as necessary. 2. Check the loading status of the transfer roller drive, and correct the error as necessary. 3. M1 operation check • Control signal: MFPB CN19E-3 to 7 • Location of electrical component: 26-C 4. Replace M1. 5. MFPB F10E conduction check 6. Replace MFPB.
