Print a Test Print.
Does the error still occur?
Go to Step 4. Problem solved.
4
Check the H-’Xport Harness continuity.
1. Disconnect the H-’Xport 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?
Go to Step 5. Repair the
harness.
5
Check for +5 V to the Entrance Sensor.
Is there +5 V across J8372-9 <=> J8372-
7 on the H-’Xport PWB?
Go to Step 6. Replace the H-
’Xport PWB
(
page 3-247).
6
Check the H-’Xport Entrance Sensor
signal.
Does the voltage across J8372-8 <=>
J8372-7 on the H-’Xport PWB change
when the sensor actuator is operated?
Replace the H-
’Xport PWB
(
page 3-247).
Replace the
sensor
(
page 3-117).
7
Test the H-’Xport Motor.
Run the Service Diagnostics H-’Xport
Motor test.
Does the motor rotate normally?
Replace the H-
’Xport PWB
(
page 3-247).
Go to Step 8.
8
Check the H-’Xport Motor connections.
Is the H-’Xport Motor correctly
connected to the harness?
Go to Step 10. Connect and go
to Step 9.
9
Print a Test Print.
Does the error still occur?
Go to Step 10. Problem solved.
10
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?
Go to Step 11. Repair the
harness.
11
Check the H-’Xport Motor resistance.
Is there some amount of resistance
across P8379-2/5(COM) and P8379-1/3/
4/6?
Go to Step 12. Replace the H-
’Xport Motor
(
page 3-113).
