Detection Description The HP of the Scanner Unit could not be detected when starting scanning operation.
Remedy
[Related parts] R1.00
- Harness between the CIS HP Sensor (J4205) and the Main Controller PCB (UN81/J4005)
- Harness between the Reader Motor (J4305) and the Main Controller PCB (UN81/J4005)
- Harness between the Main Controller PCB (J4507) and the Low-voltage Power Supply PCB
- CIS HP Sensor
- Reader Motor
- Low-voltage Power Supply PCB (UN01)
- Reader Assembly
- Main Controller PCB
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. At initial operation of the Reader startup after the main power is turned ON, check if the Reader
Motor operates (whether the Scanner Unit moves or operation sound is heard). If it operates, check
whether load on the Timing Belt for moving CIS is appropriate.
a. If it is appropriate, replace the CIS HP Sensor.
b. If it is not appropriate (overloaded), check/replace the Timing Belt, Drive Gear and pulley.
2. Check/replace the CIS Holder (soiling or damage on the surface).
3. Check/replace the related harness/cable, connector and parts.
