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

E073 0001 Title Interlock error
Description No detection of Interlock (24 V) although all the Doors (Front Cover and
Right Cover) of the host machine were closed.
Remedy [Related parts]
• Front Cover/Right Cover
• Harness between the Interlock Switch 1 and 2 (SW02 and SW03) and the
DC Controller PCB (UN04/J24/pin 1 and 2) (Unit of replacement: COVER,
INNER, FRONT, RIGHT)
• Harness between the Low-voltage Power Supply PCB (UN01/J315) and
the DC Controller PCB (UN04/J20) (Unit of replacement: CABLE, POWER
SUPPLY)
• DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB
ASSEMBLY)
• Low-voltage Power Supply PCB (UN01) (Unit of replacement: POWER
SUPPLY 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] Perform the following in the order while checking whether the error
is cleared.
1. Check that the Front Cover/Right Cover is closed.
2. Visually check that the Interlock Switch 1 and 2 are turned ON/OFF by
opening/closing the Front Cover/Right Cover.
3. Check that the harness between the Interlock Switch 1 and 2 and the DC
Controller PCB is not short-circuited (the harness does not come in contact
with the plate while the cable sheath is peeled).
4. Disconnect the connector (J24) of the DC Controller while the Front Cover
and the Right Cover are closed, and measure the resistance value between
the connectors J24/1-pin and the J24/2-pin on the J24 harness side using a
tester.
a. If the measurement value is less than 1 ohm (conduction state),
1. Replace the DC Controller PCB.
2. Replace the Low-voltage Power Supply PCB.
b. If the measurement value is 1 ohm or higher (non conduction state),
replace the harness between the Interlock Switch 1 and 2 and the DC
Controller PCB.
5. Check the harness between the Low-voltage Power Supply PCB and the
DC Controller PCB.
6. Replace the DC Controller PCB.
7. Replace the Low-voltage Power Supply PCB.
