Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the paper in the Tray.
Is the paper in the Tray loaded correctly?
Go to step 2. Load the paper.
2. Check the No Paper Sensor 250 operation.
Perform DC330 Component Control on
page 2-26 [071-101] to check the operation of
the No Paper Sensor 250.
Is the Sensor working properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 3.
3. Check the connection between the No Paper
Sensor 250 and MCU PWB.
Are the connectors P/J4652A, P/J4651A, and
P/J465A connected securely?
Go to step 4. Connect the
connectors P/J4652A,
P/J4651A, and
P/J465A.
4. Check the conductivity between the No Paper
Sensor 250 and Relay Connector.
Is the connection between P/J4652A <=>
P/J4651A conducting properly?
Go to step 5. Replace the Feeder
Harness Assembly.
5. Check the conductivity between the Relay
Connector and MCU PWB.
Is the connection between P/J4651A <=>
P/J465A conducting properly?
Go to step 6. Replace the Main
Harness Assembly.
