• Code: SC36-05
• Description: Thermistor /1 (TH1) low temperature detection (hardware). The TH1 detects an abnormal condition with the fusing error detection signal 3.
• Causes: Printer control board (PRCB) AC drive board (ACDB) Fusing heater lamp /1 (L2) Fusing heater lamp /2 (L3) Fusing heater lamp /3 (L4) Thermistor /1 (TH1) Thermistor /2 (TH2) Thermistor /3 (TH3) Thermistor /4 (TH4) Caution: • When SC34-**, SC35-** or SC36-** (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.
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC36-06
• Description: Thermistor /3 (TH3) low temperature detection (hardware). The TH3 detects an abnormal condition with the fusing error detection signal 6.
• Causes: Printer control board (PRCB) AC drive board (ACDB) Fusing heater lamp /1 (L2) Fusing heater lamp /2 (L3) Fusing heater lamp /3 (L4) Thermistor /1 (TH1) Thermistor /2 (TH2) Thermistor /3 (TH3) Thermistor /4 (TH4) Caution: • When SC34-**, SC35-** or SC36-** (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.
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC41-01
• Description: It is checked that the movement time for the scanner motor (M27) is over, and the 24V power source is also checked. The scanner home sensor (PS51) or the APS sensor /1 (PS52) does not turn ON within a specified period of time after the home position search is started. And an error detection signal (24V cut off) is detected with the scanner motor (M27).
• Causes: DC power supply /1 (DCPS/ 1)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC41-02
• Description: The blowout of a fuse for the scanner motor (M27) in the scanner drive board (SDB) is checked. The scanner home sensor (PS51) or the APS sensor /1 (PS52) does not turn ON within a specified period of time after the home position search is started. And an error detection signal (blowout of a fuse) is detected with the M27. At this time, an error detection signal (24V cut off) is not detected with the M27.
• Causes: Scanner drive board (SDB) Scanner motor (M27)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC41-03
• Description: The time for the movement of the scanner motor (M27) is over. The scanner home sensor (PS51) or the APS sensor /1 (PS52) does not turn ON within a specified period of time after the home position search is started. And an error detection signal (blowout of a fuse/24V cut off) is not detected with the M27.
• Causes: Scanner drive board (SDB) Scanner motor (M27) Scanner home sensor (PS51)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC41-10
• Description: The abnormal speed of the polygon motor (M21) is checked, and the 24V power source is also checked. When switching the speed of the M21, the lock signal of the M21 is not detected within a specified period of time after the switchover is started, and an error detection signal (24V cut off) is detected.
• Causes: DC power supply /1 (DCPS/ 1)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC41-11
• Description: The abnormal speed of the polygon motor (M21) is checked. When switching the speed of the M21, the lock signal of the M21 is not detected within a specified period of time after the switchover is started.
• Causes: Polygon motor (M21) Printer control board (PRCB)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).

• Code: SC42-01
• Description: The rotation of the scanner cooling fan (FM19) is checked, and 24V power source is also checked. An abnormal condition occurs with the FM19 EM signal a specified period of time after the FM19 turns ON. This abnormal condition recurs even a specified period of time after the FM19 is turned OFF and then turned ON, and an error detection signal (24V cut off) is detected.
• Causes: DC power supply /2 (DCPS/ 2)
• Remedy: The main body stops immediately to turn OFF the RL1 (main).
