Troubleshooting Procedure
Step Actions and Questions Yes No
1. Check the Duplex Jam Sensor operation.
Perform DC330 Component Control on
page 2-26 [071-128] to check the operation of
the Duplex Jam Sensor.
Is the Duplex Jam Sensor operating properly?
Replace the MCU PWB
(REP 12.4 MCU PWB
on page 4-206).
Go to step 2.
2. Check the connection between the Duplex Jam
Sensor and Duplex PWB.
Are the connectors P/J125 and P/J430 connected
securely?
Go to step 3. Connect the
connectors P/J125 and
P/J430.
3. Check the conductivity between the Duplex Jam
Sensor and Duplex PWB.
Is the connection between P/J125 <=> P/J430
conducting properly?
Go to step 5. Replace the Option
Duplex Sensor Harness
Assembly.
4. Check the voltage supply (+3.3VDC) to the
Duplex Jam Sensor.
Measure the voltage between the Duplex PWB
GND <=> P/J430-1.
Is there a voltage (approx. +3.3VDC) output?
Replace the Duplex
Jam Sensor (REP 14.7
Duplex Jam Sensor on
page 4-259).
Go to step 5.
5. Check the voltage supply (+3.3VDC) to the
Duplex PWB.
Measure the voltage between the Duplex PWB
GND <=> P/J428-7.
Is there a voltage (approx. +3.3VDC) output?
Replace the Duplex
PWB (REP 14.6 Duplex
PWB on page 4-257).
Go to step 6.
