10.8.6 Duplex Sensor Assembly Failure

1 There is a +5VDC between P213-1 and P213-2.
Y: Go to step 6.
N: Go to step 2.
2 There is a +5VDC between P124-8 and P124-7.
Y: Replace the Duplex PWB.
N: Go to step 3.
3 There is a +5VDC between P115-6 and P115-2.
Y: Replace the Fuser PWB.
N: Go to step 4.
4 There is a +5VDC between P111-A4 and P111-A3.
Y: Replace the HVPS.
N: Go to step 5.
5 There is a +5VDC between P15-A9 and P15-A10.
Y: Replace the Print Engine Controller to the HVPS Harness.
N: Replace the Print Engine Controller. If the problem is not resolved, go to RAP 7.4.5 Low
Voltage Power Supply (LVPS) Assembly Failure (+5VDC).
6 The voltage is between P213-3 and P213-2 at a high level when the Duplex Sensor is not
actuated and at a low level when actuated.
Y: Go to step 7.
N: Verify the continuity of the Sensor Harness. If this is fine, replace the Duplex Sensor.
7 The voltage is between P117-2 and P117-7 at a high level when the Duplex Sensor is not
actuated and at a low level when actuated.
Y: Go to step 8.
N: Replace the Duplex PWB.
8 The voltage is between P115-11 and P115-2 at a high level when the Duplex Sensor is not
actuated and at a low level when actuated.
Y: Go to step 9.
N: Replace the Fuser PWB.
9 The voltage is between P15-A5 and P15-A10 at a high level when the Duplex Sensor is not
actuated and at a low level when actuated.
Y: Replace the Print Engine Controller.
N: Validate the continuity of the Print Engine to the HVPS Harness. If this is fine, replace
the HVPS.
