Jam at A (H-X'port Entrance Sensor) Troubleshooting Procedure (Continued)
Step Actions and Questions
5 Check the H-'Xport Harness continuity.
1. Disconnect the Entrance Sensor (J8380)
and P8372 on the H-'Xport PWB.
2. Check for continuity at the following:
P8372-7 <=> J8380-3
P8372-8 <=> J8380-2
P8372-9 <=> J8380-1
Are these conductive?
6 Check for +5 V to the Entrance Sensor.
Is there +5 V across J8372-9 <=> J8372-
7 on the H-'Xport PWB?
7 Check the Entrance Sensor signal.
Does the voltage across J8372-8 <=>
J8372-7 on the H-'Xport PWB change
when the sensor actuator is operated?
8 Check the H-'Xport Motor.
Run the Service Diagnostics H-'Xport
Motor test.
Does the motor rotate normally?
9 Check the H-'Xport Motor connections.
Is the H-'Xport Motor correctly
connected to the harness?
10 Print a Test Print.
Does the error still occur?
11 Check the harness for continuity.
1. Disconnect P/J8379 of the H-'Xport
Motor, and P8372 on the H-'Xport PWB.
2. Check for continuity at the following:
P8372-13 <=> J8379-6
P8372-12 <=> J8379-4
P8372-11 <=> J8379-1
P8372-10 <=> J8379-3
P8372-15 <=> J8379-2
P8372-3 <=> J8379-5
Are these conductive?
12 Check the H-'Xport Motor resistance.
Is there some amount of resistance
across P8379-2/5(COM) and P8379-1/3/
4/6?
13 Check for +24 V to the H-'Xport Motor.
Is there +24 V across J8372-15 <=>
J8372-7, and J8372-14 <=> J8372-7 on
the H-'Xport PWB?
