• Code: SC53-07
• Description: The blowout of a 5V ICP for the AC drive board (ACDB) is checked. In the serial initial communication, a signal of the blowout of a 5V ICP (AC drive) is detected.
• Causes: Printer control board (PRCB) AC drive board (ACDB) DC power supply /1 (DCPS1) Loose connection

• Code: SC53-08
• Description: The 12V power source in the printer control board (PRCB) is checked. An error detection signal of the 12V in PRCB is detected.
• Causes: Printer control board (PRCB) AC drive board (ACDB) DC power supply /1 (DCPS1) Loose connection

• Code: SC53-11
• Description: The 24V power source for the SD/CL in the printer control board (PRCB) is checked. At the start, an error detection signal (blowout of ICP for the solenoid/clutch) is detected, and an error detection signal (24V cut off) is also detected.
• Causes: Each of the solenoids Each of the clutches Printer control board (PRCB) Wiring harness earth fault

• Code: SC53-12
• Description: The blowout of ICP for the SD/CL in the printer control board (PRCB) is checked. At the start, an error detection signal (blowout of ICP for the solenoid/clutch) is detected. However, an error detection signal (24V cut off) is not detected.
• Causes: Each of the solenoids Each of the clutches Printer control board (PRCB) Wiring harness earth fault

• Code: SC60-01
• Description: Although the main body sends out data according to the data retransmission request made by the DF, a retransmission request signal is received again.
• Causes: Overall control board (OACB) DF control board (DFCB) Communication system cable

• Code: SC60-02
• Description: When a checksum error or an SRGA reception error was detected while in the reception in serial communication, a signal was sent to make a request for sending data again. And when data is being received upon this request, a checksum error or an SRGA reception error is detected again.
• Causes: Overall control board (OACB) DF control board (DFCB) Communication system cable

• Code: SC60-03
• Description: When the main power switch (SW1) is ON, there is no response to the initial communication request from the main body to the DF even after a specified period of time elapses.
• Causes: DF control board (DFCB)

• Code: SC60-11
• Description: When the main power switch (SW1) is ON, a region into which no write was made by the ISW is detected in the DF control program.
• Causes: DF control board (DFCB) DF program
