Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the Bypass Tray No Paper Sensor
operation.
Perform DC330 Component Control on
page 2-26 [071-100] to check the operation of
the Bypass Tray No Paper Sensor.
Is the Sensor working properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 2.
2. Check the connection of the Bypass Tray No
Paper Sensor.
Check the connection between the Bypass Tray
No Paper Sensor and MCU PWB.
Are the connectors P/J4752, P/J4751, and P/J475
connected securely?
Go to Step 3 Connect the
connectors P/J4752,
P/J4751, and P/J475.
3. Check the conductivity between the Bypass Tray
No Paper Sensor and Relay Connector.
Is the connection between P/J4752 <=> P/J4751
conducting properly?
Go to step 4. Replace the Front
Harness Assembly.
4. Check the conductivity between the Relay
Connector and MCU PWB.
Is the connection between P/J4751 <=> P/J475
conducting properly?
Go to step 5. Replace the Main
Harness Assembly.
