(Wiring diagram: Main body (2/4): 13-A) 4. Replace FM44. 5. Replace PRCB. 6. Replace ACDB.

Code: C-2401
Description: The fall-off of the erase lamp (EL) CN is detected. When turning ON the power, an error detection signal (fall-off) is detected a specified period of time after the fall-off detection control signal of the EL CN turns ON.
Causes: • Erase lamp (EL) • Printer control board (PRCB)
Remedy: 1. Check the EL section, and clean/repair it if any abnormality. (Wiring diagram: Main body: 15-I) 2. Check the connector connection and the wiring between PRCB and EL, and repair it if any abnormality. 3. Replace EL. 4. Replace PRCB.

Code: C-2402
Description: Drum temperature sensor wiring harness breakage. When the change in temperature of the drum temperature sensor (TH5) is less than -2°C a specified period of time after the main power switch (SW1) turns ON to start the control of the dehumidification heater /1 (HTR1) and the drum temperature is below 10°C after 1minute.
Causes: • Drum temperature sensor (TH5) • Printer control board (PRCB)
Remedy: 1. Check the connector connection and the wiring between PRCB and TH5, and repair it if any abnormality. 2. Check TH5, and repair/replace it if any abnormality. (Wiring diagram: Main body (3/4): 20-I) 3. Replace TH5. 4. Replace PRCB.

Code: C-2403
Description: Drum temperature sensor wiring harness breakage. When the main power switch (SW1) turns ON with the fusing temperature below 50°C, the detected temperature of the drum temperature sensor (TH5) is more than 52°C, and when the detected temperature is above 52°C after a specified period of time.
Causes: • Drum temperature sensor (TH5) • Printer control board (PRCB)
Remedy: 1. Check the connector connection and the wiring between PRCB and TH5, and repair it if any abnormality. 2. Check TH5, and repair/replace it if any abnormality. (Wiring diagram: Main body (3/4): 20-I) 3. Replace TH5. 4. Replace PRCB.

Code: C-2411
Description: TCR sensor (TCRS) output abnormality 1. The TCRS output is detected more than 3.0V (153step) in printing.
Causes: • TCR sensor (TCRS) • Printer control board (PRCB)
Remedy: 1. Check the TCRS, and clean/replace it if any abnormality or dirt on sensor (Wiring diagram: Main body (3/4): 20-I) 2. Check the developing section, and clean/repair it if there is sensor dirt or any abnormality. 3. Check the connector connection and the wiring between PRCB and TCRS, and repair it if any abnormality. 4. Replace TCRS. 5. Replace PRCB.

Code: C-2412
Description: TCR sensor (TCRS) output abnormality 2. The TCRS output is detected more than 0.5V (25step) in printing.
Causes: • TCR sensor (TCRS) • Printer control board (PRCB)
Remedy: 1. Check the TCRS, and clean/replace it if any abnormality or dirt on sensor (Wiring diagram: Main body (3/4): 20-I) 2. Check the developing section, and clean/repair it if there is sensor dirt or any abnormality. 3. Check the connector connection and the wiring between PRCB and TCRS, and repair it if any abnormality. 4. Replace TCRS. 5. Replace PRCB.
