Code: C-3803
Description: Thermistor /1 (TH1) detects a low temperature when a specified period of time elapses after the fusing heater lamp is turned ON for the fusing ON control.
Causes: Printer control board (PRCB) Fusing heater lamp /1 (L2) Fusing heater lamp /2 (L3) Fusing heater lamp /3 (L4) Thermistor /1 (TH1) Thermistor /2 (TH2) NOTE • C-3401 to C-3901 (fusing temperature related abnormalities) occur, be sure to repair defective parts before setting the software DipSW3-1 to 0. • Setting the DipSW3-1 to 0 with defective parts not repaired may result in a fire.

Code: C-3807
Description: The temperature of heater does not reach the specified temperature during warming up in alarm recovery.
Causes: Printer control board (PRCB) Fusing heater lamp /1 (L2) Fusing heater lamp /2 (L3) Fusing heater lamp /3 (L4) Thermistor /1 (TH1) Thermistor /2 (TH2) NOTE • C-3401 to C-3901 (fusing temperature related abnormalities) occur, be sure to repair defective parts before setting the software DipSW3-1 to 0. • Setting the DipSW3-1 to 0 with defective parts not repaired may result in a fire.

Code: C-3901
Description: Thermistor /1 (TH1) does not reach a specified temperature when a specified period of time elapses after the power switch (SW2) is turned ON for the fusing ON control.
Causes: Printer control board (PRCB) Fusing power board (FPB) Fusing heater lamp /1 (L2) Fusing heater lamp /2 (L3) Fusing heater lamp /3 (L4) Thermistor /1 (TH1) Thermistor /2 (TH2) NOTE • C-3401 to C-3901 (fusing temperature related abnormalities) occur, be sure to repair defective parts before setting the software DipSW3-1 to 0. • Setting the DipSW3-1 to 0 with defective parts not repaired may result in a fire.

Code: C-4101
Description: The lock signal of the polygon motor (M15) is not detected within a specified period of time when M15 starts or changes its speed.
Causes: Polygon motor (M15) Polygon motor drive board (PMDB) Printer control board (PRCB)

Code: C-4301
Description: The WRFAN1_EM signal shows an abnormal condition when a specified period of time elapses after the polygon cooling fan (FM2) turns ON. This abnormal condition recurs when a specified period of time elapses after FM2 is turned OFF and then ON again.
Causes: Polygon cooling fan (FM2) Printer control board (PRCB)

Code: C-4704
Description: While in the execution of APC, no change is found in the output of the index sensor.
Causes: Write unit Power connector of the overall control board (OACB)

Code: C-4705
Description: While in the image write, the expansion processing of image data from the memory to the printer is not correctly terminated. The output from the page memory to the printer does not terminate within a specified period of time.
Causes: Printer control board (PRCB) Overall control board (OACB)

Code: C-4707
Description: One of the following APC errors is detected: • APC is not applicable. • The 12V DC power for the laser drive is not supplied. • MPC is wrong. • Due to the laser defective, the laser does not light up. Or, the index sensor cannot detect the laser due to the followings: • The polygon mirror does not rotate. • The position of the index sensor is not correct. • The index sensor is defective.
Causes: Write unit Power connector of the overall control board (OACB) Printer control board (PRCB)
