Code :

Code: C-4315#
Description: When the print is started, an error detection signal of the polygon cooling fan (FM9) is detected.
Causes: Confirmation of the wiring harness and the connector Polygon cooling fan (FM9) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

Code: C-4701
Description: FIFO address abnormality for the printer. While in the image write, the expansion processing of image data that is read in is not correctly terminated.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Gate array damaged

Code: C-4702
Description: An error interrupt occurs with the compression/expansion chip FIFO.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Gate array damaged

Code: C-4703
Description: Elongation abnormality.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Gate array damaged

Code: C-4704
Description: While in the execution of APC, no change is found in the output of the index sensor.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Write unit DC power supply /1 (DCPS1)

Code: C-4705
Description: While in the image write, the expansion processing from the memory to the printer does not terminate within a specified period of time. The output from the page memory to the printer does not terminate within a specified period of time. The PVV is not detected within a specified period of time.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Printer control board (PRCB)

Code: C-4706
Description: When writing images, in spite of no resource provided, an inappropriate processing such as an access to the elongation device is made.
Causes: Confirmation of the wiring harness and the connector Reinstalling firmware Overall control board (OACB) Printer control board (PRCB)

Code: C-4707
Description: While in the image write, APC is not applicable for the correction of the sub scan beam. Due to the 12V DC power for the laser drive not supplied, the MPC being wrong and the laser defective, the laser does not light up. Also, due to the rotation of the polygon mirror unavailable, the displacement of the index sensor, and the index sensor being defective, the index sensor cannot detect the laser.
Causes: Confirmation of the wiring harness and the connector Overall control board (OACB) Write unit DC power supply /1 (DCPS1)
