Laser Scanner error
BD signal was not detected although a specified period of time had passed during operation of the
Laser Scanner (Y, M).
[Related parts] R1.01
- Small-diameter Coaxial Cable connecting from the Riser PCB (J9) to the Laser Driver PCB (Y)
and (M) (UN13/J101 and UN12/J822)
- Connector between the Main Controller PCB and the Riser PCB
- Harness between the DC Controller PCB (UN1/J171) and the Laser Driver PCB (Y) (UN13/J851)
- Harness between the Relay PCB (UN5/J416) and the Laser Driver PCB (M) (UN12/J830)
- Laser Driver PCB (Y) (UN13)
- Laser Driver PCB (M) (UN12)
- 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.
