EEPROM communication error
EEPROM data in DCON could not be read at startup.
[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.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
EEPROM communication error
The number of read/write job data (device information) to the DCON EEPROM exceeded the
specified value.
[Remedy] Turn OFF and then ON the main power.
[Reference] Data (device information) is reset by turning OFF and then ON the main power.
EEPROM communication error
The NACK (a negative reply sent by the reception side to the sending side) was received for 3
times in communication from the DC Controller PCB (CPU) to the SCNR EEPROM.

EEPROM communication error
Although access to the SCNR EEPROM from the DC Controller PCB (CPU) was executed for 3
times, no response was received and timeout occurred.
