• Code: SC23-07
• Description: It is checked that the movement of the blade motor (M14) is not completed, and 24V power source is also checked. The blade READY signal (READY condition) cannot be detected within a specified period of time after the blade replacement signal turns ON. Or, the blade READY signal (READY release condition) cannot be detected within a specified period of time after the blade replacement signal turns OFF. At this time, an error detection signal (24V cut off) is detected.
• Causes: Drum motor (M2) Blade motor (M14) Printer control board (PRCB) Blade sensor /1 (PS30) Blade sensor /2 (PS31) DC power supply /2 (DCPS2) Wiring harness broken Loose connection

• Code: SC23-08
• Description: The blowout of ICP for the blade motor (M14) in the printer control board (PRCB) is checked. The blade READY signal (READY condition) cannot be detected within a specified period of time after the blade replacement signal turns ON. Or, the blade READY signal (READY release condition) cannot be detected within a specified period of time after the blade replacement signal turns OFF. At this time, an error detection signal (blowout of ICP) of M14 is detected.
• Causes: Drum motor (M2) Blade motor (M14) Printer control board (PRCB) Blade sensor /1 (PS30) Blade sensor /2 (PS31) DC power supply /2 (DCPS2) Wiring harness broken Loose connection

• Code: SC23-09
• Description: It is checked that the movement of the blade motor (M14) is not completed. The blade READY signal (READY condition) cannot be detected within a specified period of time after the blade replacement signal turns ON. Or, the blade READY signal (READY release condition) cannot be detected within a specified period of time after the blade replacement signal turns OFF. At this time, an error detection signal is not detected.
• Causes: Blade motor (M14) Printer control board (PRCB) Blade sensor /1 (PS30) Blade sensor /2 (PS31) Wiring harness broken Loose connection

• Code: SC23-10
• Description: It is checked that the drum motor (M2) does not start. The drum READY2 signal (READY signal) is not detected within a specified period of time after M2 turns ON.
• Causes: Drum motor (M2) Printer control board (PRCB) Loose connection

• Code: SC23-11
• Description: The blowout of ICP for the toner supply motor (M11) in the printer control board (PRCB) is checked. An error detection signal (blowout of ICP) is detected when M11 turns ON.
• Causes: Toner supply motor (M11) Wiring harness broken

• Code: SC23-21
• Description: When the recycle pump motor (M24) is turned ON, an error detection signal is detected twice in a row within a specified period of time. (An error detection signal on the first time is ignored.)
• Causes: Recycle pump motor (M24) Recycle pump drive board (RCDB)

• Code: SC24-01
• Description: The temperature of the drum temperature sensor (TH5) detected a specified period of time after the main power switch (SW1) is turned ON is -3°C or lower, and also, the drum temperature after a specified period of time is -3°C or lower.
• Causes: Printer control board (PRCB) Drum temperature sensor (TH5)

• Code: SC24-02
• Description: 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: Printer control board (PRCB) Drum temperature sensor (TH5)
