Laser Shutter Error
Home position was not detected although the Laser Shutter was closed.
[Related parts] R1.00
- Harness connecting from the Feed/Drum Driver PCB (UN2/J224) to the Laser Shutter Motor and
Laser Shutter Sensor (M28/J6060 and PS29/J6123)
- Laser Shutter Sensor (PS29)
- Laser Shutter Motor (M28)
- Feed/Drum Driver PCB (UN2)
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check that the Laser Shutter Motor is properly installed.
2. Check that there is no damage or deformation with the Laser Shutter Sensor Flag.
3. Check/replace the related harness/cable, connector and parts.
