Check Stack Height Sensor 1 Sensor
Harness continuity.
1. Disconnect P/J8331 on the Main Sensor
Harness, and P/J8302B on the Finisher
Main PWB.
2. Check for continuity at the following:
P/J8331-5 <=> P/J8302B-1
P/J8331-4 <=> P/J8302B-2
P/J8331-3 <=> P/J8302B-3
P/J8331-2 <=> P/J8302B-4
P/J8331-1 <=> P/J8302B-5
Are these conductive?
Go to Step 6. Repair the Stack
Height Sensor 1
Sensor Harness.
6
Check for +5 V to Stack Height Sensor 1.
Is there +5 V across J8302B-3 <=>
J8302B-1 on the Finisher Main PWB?
Go to Step 7. Replace the
Finisher Main
PWB
(
page 3-248).
7
Check Stack Height Sensor 1 signal.
Does the voltage across P8302B-2 <=>
P8302B-1 on the Finisher Main PWB
change when the sensor is blocked?
Replace the
Finisher Main
PWB
(
page 3-248).
Replace Stack
Height Sensor 1
(
page 3-140).
8
Test the Stack Height Sensor 2 (bottom).
Run the Service Diagnostics Stack Height
Sensor 2 test.
NOTE: Sensor requires a 10 second
timeout between sensing events.
Does the sensor state change when the
sensor is blocked?
Go to Step 14. Go to Step 9.
9
Check Stack Height Sensor 2 Sensor
Harness connections.
Are P/J8330 and P/J8302A connected?
Go to Step 11. Connect and go
to Step 10.
10
Print a Test Print.
Does the error still occur?
Go to Step 11. Problem solved.
11
Check Stack Height Sensor 2 Sensor
Harness continuity.
1. Disconnect P/J8330 on the harness, and
P/J8302A on the Finisher Main PWB.
2. Check for continuity at the following:
P/J8330-5 <=> P/J8302A-16
P/J8330-4 <=> P/J8302A-17
P/J8330-3 <=> P/J8302A-18
P/J8330-2 <=> P/J8302A-19
P/J8330-1 <=> P/J8302A-20
Are these conductive?
Go to Step 12. Repair the Stack
Height Sensor 2
Harness.
