• Code: SC80-40
• Description: When the main power switch (SW1) is ON, a region into which no write was made by the ISW is detected in the FS control program.
• Causes: FS control program

• Code: SC80-45
• Description: When the main power switch (SW1) is ON, a region into which no write was made by the ISW is detected in the IC program.
• Causes: IC program

• Code: SC90-01
• Description: Initial communication check between the ADU drive board (ADUDB)/ printer control board (PRCB). ADU drive serial input abnormality 1. Within a specified period of time after the ACK at the time of the main power switch (SW1) being turned ON, a serial data from ID = 0 of the ADUDB is not received.
• Causes: ADU drive board (ADUDB) Printer control board (PRCB) Loose connection

• Code: SC90-02
• Description: Communication error check between the ADU drive board (ADUDB)/ printer control board (PRCB). ADU drive serial input abnormality 1. Within a specified period of time after the ACK at the time of the main power switch (SW1) being turned ON, a serial data from ID = 7 of ADUDB is not received.
• Causes: ADU drive board (ADUDB) Printer control board (PRCB) Loose connection

• Code: SC93-01
• Description: 12V ICP blowout in the ADU drive board (ADUDB). A -5V ICP blowout signal and blowout of a 12V ICP signal are detected for the serial initial communication.
• Causes: ADU drive board (ADUDB) Printer control board (PRCB) Loose connection

• Code: SC93-05
• Description: 24V power source check. At the start of operation, an error detection signal (solenoid/blowout of clutch ICP) is detected, and also an error detection signal (24V cut off) is detected.
• Causes: Each of the solenoids Each of the clutches DC power supply /2 (DCPS2) Loose connection Wiring harness earth fault ADU drive board (ADUDB)

• Code: SC93-06
• Description: At the start of operation, an error detection signal (solenoid/blowout of clutch ICP) is detected. However, an error detection signal (24V cut off) is not detected.
• Causes: Each of the solenoids Each of the clutches DC power supply /2 (DCPS2) Loose connection Wiring harness earth fault ADU drive board (ADUDB)

• Code: SC95-01
• Description: A specified period of time after the ADU cooling fan /1 (FM10), /2 (FM11) turns on, the F10/11 signal gets into an abnormal condition. This abnormal condition still recurs a specified period of time after it is turned ON again after being turned OFF, and also an error detection signal (24V cut off) is detected.
• Causes: DC power supply /2 (DCPS2) ADU drive board (ADUDB) ADU cooling fan /1 (FM10) ADU cooling fan /2 (FM11) Wiring harness earth fault Loose connection
