Status Indicator RAPs Initial issue
12-303 H Transport Interlock Open
The H Transport Interlock Sensor detected open.
Procedure
Block the H Transport Interlock Sensor with a sheet of paper ( Figure 1 ). 012-303 is cleared.
Y N
+5 VDC is measured between the H Transport Interlock Sensor P/J853-1 and -3
(
Figure 2 ).
Y N
Disconnect Finisher PWB P/J845 . +5 VDC is measured between Finisher PWB
P845-A1 and -A3.
Y
N
Replace the Finisher PWB ( PL 17.13 ) ( Figure 3 ).
Repair the open circuit between Finisher PWB J845-A1 and -A3 and H Transport
Interlock Sensor J853-1 and -3.
+5 VDC is measured between Finisher PWB P/J845-A2 and ground.

Replace the Finisher PWB ( PL 17.13 )
+5 VDC is measure between H Transport Interlock Sensor P/J853-2 and ground.
Y
N
Check the wire between the H Transport Interlock Sensor P/J853-2 and the Finisher
PWB
P/J845 -A2 for an open circuit or poor contact.
Replace the H Transport Interlock Sensor ( PL 17.4 ).
Check misalignment between the H Transport Cover and the H Transport Interlock Sensor.
Check the H Transport Cover for improper installation, the Actuator for breakage and bending,
and the Magnet for improper mounting.
