Code: C-3402
Description: Fusing error detection 2 • Loose connection of the ADU drive board (ADUDB) and the printer control board (PRCB) • The malfunction of the serial communication • The malfunction of the sub- CPU on ADU
Causes: ADU drive board (ADUDB) Printer control board (PRCB) 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-3501
Description: Thermistor /1 (TH1) detects a temperature over a specified temperature 5 times in succession in a specified period.
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-3502
Description: Thermistor /1 (TH1) detects the followings: • The temperature of the sensor for detection is over a specified temperature. • The temperature of the sensor for compensation is over a specified temperature. • The temperature of the middle part of the fusing roller is over a specified temperature.
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-3503
Description: Thermistor /2 (TH2) detects a high temperature or a low temperature.
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-3801
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.
