E029 5008 05 Title Registration Patch Sensor (Front) light intensity error
Detection The background regular reflection output of the Registration
description Patch Sensor at the front side did not fall within the specified
range for 2 consecutive times at initialization.
Remedy [Related parts]
- Registration Patch Sensor Unit (Front) (UN31) (Unit of
replacement: REGISTRATION SENSOR ASSEMBLY)
- Registration Patch Sensor Unit (Front) Shutter (Unit of
replacement: SHUTTER, REGISTRATION SENSOR)
- Registration Shutter Solenoid (SL03) (Unit of replacement:
SOLENOID)
- Harness between the Registration Patch Sensor Unit (Front)
and the DC Controller PCB
1. Registration Patch Sensor Unit (Front) (UN31/J5603) to
Relay Connector (16P) (Unit of replacement: CABLE, REG.
DETECT)
2. Relay Connector (16P) to Relay Connector (16P) (Unit of
replacement: CABLE CONNECTING ASSEMBLY)
3. Relay Connector (16P) to DC Controller PCB (UN04/J170)
(Unit of replacement: 2ST TRANS. H.V. CONTACT ASS'Y)
- DC Controller PCB (UN04) (Unit of replacement: DC
CONTROLLER PCB ASSEMBLY)
[Points to note at work] When checking the harness/cable or
connector, perform the following work.
1. Disconnect and then connect the connector to check that
there is no bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.
3. If there is any error, replace the corresponding harness/cable.

Remedy [Remedy] Perform the following in the order while checking
whether the error is cleared.
Check the background regular reflection output value (front) in
COPIER (level 2)> DISPLAY> DENS> P-B-P-C.
a. If the value is less than 10,
1. Check if the sensor window of the Registration Patch
Sensor Unit (Front) is soiled. If it is soiled, clean it with a blower.
2. Check that the Registration Patch Sensor Unit (Front)
Shutter is properly installed and it is not damaged or deformed.
If it is deformed or damaged, replace the Registration Patch
Sensor Unit (Front).
3. Check the operation of the Registration Shutter Solenoid.
3-1. If the Registration Shutter Solenoid moves,
3-1-1. Replace the Registration Patch Sensor Unit (Front).
3-1-2. Replace the DC Controller PCB.
3-2. If the solenoid does not move, replace the Registration
Shutter Solenoid.
b. If the value is above 250,
1. Check the harness between the Registration Patch Sensor
Unit (Front) and the DC Controller PCB.
2. Replace the harness between the Registration Patch
Sensor Unit (Front) and the DC Controller PCB.
3. Replace the Registration Patch Sensor Unit (Front).
4. Replace the DC Controller PCB.
[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.
