EEPROM communication error
Although write polling to the SCNR EEPROM from the DC Controller PCB (CPU) was performed
for 3 times, no response was received and timeout occurred.
[Related parts] R1.00
- Harness between the DC Controller PCB (UN04/J110) and the Y/M/C/Bk Laser Driver PCB
(UN05/J202)
- Harness between the DC Controller PCB (UN04/J184) and the Developing High-voltage PCB
(UN06/J241)
- Y/M/C/Bk Laser Driver PCB (UN05)
- Developing High-voltage PCB (UN06)
- DC Controller PCB (UN04)
[Remedy] Check/replace the related harness/cable, connector and parts.
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.
