PWB Chassis (-).
YN
Check the wire between the H Transport Interlock Sensor p/j and the Finisher PWB
p/j for an open circuit or poor contact.
+5 VDC is measured between the H Transport Interlock Sensor p/j (+) and 3 (-).
YN
Check the wire between the Finisher PWB p/j and the H Transport Interlock Sensor
p/j and between the Finisher PWB p/j and H Transport Interlock Sensor p/j for an
open circuit or poor contact.
If no problems are found, replace the Finisher PWB (PL 17.13).
Replace the H Transport Interlock Sensor (PL 17.4).
