Code :

Code: C-4708
Description: When accessing to the memory device, a defective software is detected.
Causes: Confirmation of the wiring harness and the connector Reinstalling firmware Overall control board (OACB) Printer control board (PRCB)

Code: C-4709
Description: The expansion processing from the memory to the page memory is not terminated within a specified period of time. The compression processing from the page memory to the memory is not terminated within a specified period of time. The development from the memory into the page memory is not terminated within a specified period of time. The transmission of the compressed data from memory to memory is not terminated within a specified period of time.
Causes: Confirmation of the wiring harness and the connector Reinstalling firmware Overall control board (OACB) Printer control board (PRCB)

Code: C-4721#
Description: The print operation starts before the paper mis-centering adjustment is terminated. (The mis-centering adjustment is too late.)
Causes: Confirmation of the wiring harness and the connector Centering sensor (PS1) ADU drive board (ADUDB)

Code: C-4722#
Description: A PWM gamma curve is not created properly.
Causes: Cleaning of the IDC sensor Confirmation of the wiring harness and the connector IDC sensor board (IDCB) Printer control board (PRCB)

Code: C-5010#
Description: Communication error check between OACB/PRCB. Overall control board (OACB) communication serial reception error detection abnormality.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Printer control board (PRCB)

Code: C-5101
Description: A speed error signal of the fusing motor (M1) is checked. An error detection signal is detected twice in succession a specified period of time after M1 turns ON. (The first signal is ignored.)
Causes: Confirmation of the wiring harness and the connector Fusing motor (M1) Printer control board (PRCB) DC power supply /2 (DCPS2)

Code: C-5102#
Description: The 24V power source for the total counter (TCT) is checked. When TCT is turned ON from OFF, an error detection signal (blowout of ICP/24V cut off) is detected.
Causes: Confirmation of the wiring harness and the connector Total Counter (TCT) AC drive board (ACDB) DC power supply /2 (DCPS2)

Code: C-5103#
Description: The blowout of ICP for TC in the AC drive board (ACDB) is checked. When the total counter (TCT) is turned ON from OFF, an error detection signal (blowout of ICP) is detected. However, an error detection signal (24V cut off) is not detected.
Causes: Confirmation of the wiring harness and the connector Total Counter (TCT) AC drive board (ACDB) DC power supply /2 (DCPS2)
