Laser Scanner error
Correction in timing of laser exposure to the Polygon Mirror (C, Bk) was not completed within the
specified period of time.
[Related parts] R1.00
- Small-diameter Coaxial Cable connecting from the Riser PCB (J9) to the Laser Driver PCB (C)
and (Bk) (UN15/J802 and UN14/J822)
- Connector between the Main Controller PCB and the Riser PCB
- Harness between the DC Controller PCB (UN1/J171) and the Laser Driver PCB (C) (UN15/J862)
- Laser Driver PCB (C) (UN15)
- Laser Driver PCB (Bk) (UN14)
- Main Controller PCB
- Riser PCB
- DC Controller PCB (UN1)
[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 error
An error in check sum of EEPROM on the Laser Scanner was detected (Y, M).
