E074 0000 Title
Primary Transfer Roller disengagement control error
Description Signal was not detected although the ITB Pressure Release Switch was
turned ON/OFF for 6 times.
Remedy
[Related parts]
• ITB Unit (Unit of replacement: INTER. TRANSFER BELT ASS’Y)
• Harnesses from the DC Controller PCB to the ITB Pressure Release Switch
1. DC Controller PCB (UN04/J162) to Relay Connector (2P) (Unit of
replacement: PROCESS CONTROL PCB ASS’Y)
2. Relay Connector (2P) to ITB Pressure Release Switch (SW07/J6005)
• Harness between the DC Controller PCB (UN04/J140) and the Primary
Transfer Separation Solenoid (SL01/J5708) (Unit of replacement: MAIN
DRIVE ASSEMBLY)
• Fuse in the DC Controller PCB (UN04/FU07) (Unit of replacement: DC
CONTROLLER PCB ASSEMBLY)
• ITB Guide Rail (Unit of replacement: RAIL, I.T.B., FRONT/RAIL, I.T.B.,
REAR)
• Main Drive Unit (Unit of replacement: MAIN DRIVE ASSEMBLY)
• 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] Perform the following in the order while checking whether the error
is cleared.
1. Check that the ITB Unit is installed in the machine.
2. Replace the ITB Unit.
3. Check the harness between the DC Controller PCB and the ITB Pressure
Release Switch.
4. Check the harness between the DC Controller PCB and the Primary
Transfer Separation Solenoid.
5. Measure the both ends of the fuse in the DC Controller PCB using a tester.
a. If the measurement value is less than 1 ohm (conduction state),
1. Replace the ITB Guide Rail (Front/Rear).
2. Replace the Main Drive Unit.
3. Replace the DC Controller PCB.
b. If the measurement value is 1 ohm or higher (non conduction state), replace
the DC Controller PCB.
[Caution] After replacing the DC Controller PCB, measure the resistance
value between the Low-voltage Power Supply PCB (UN01/J315/4-pin) and
the DC Controller PCB (UN04/J20/1-pin) using a tester before turning ON the
main power to prevent blowout of a fuse again. If the measurement value is 1
ohm or higher (non conduction state), perform the following in the order while
checking whether the error is cleared.
1. Replace the harness between the DC Controller PCB and the ITB Pressure
Release Switch.
2. Replace the harness between the DC Controller PCB and the Primary
Transfer Separation Solenoid.
