Check Stacker Encoder Sensor Harness
connections.
Are P/J8328 and P/J8302B connected?
Go to Step 6. Connect and go
to Step 5.
5
Print a Test Print.
Does the error still occur?
Go to Step 6. Problem solved.
6
Check Stacker Encoder Sensor Harness
continuity.
1. Disconnect the sensor P/J8328, and P/
J8302B on the Finisher Main PWB.
2. Check for continuity at the following:
P/J8328-3 <=> P/J8302B-12
P/J8328-2 <=> P/J8302B-13
P/J8328-1 <=> P/
J8302B-14
Are these conductive?
Go to Step 7. Repair the
Stacker Encoder
Sensor Harness.
7
Check for +5 V to the Stacker Encode
Sensor.
Is the voltage across J8302B-14 <=>
J8302B-12 on the Finisher Main PWB?
Go to Step 8. Replace the
Finisher Main
PWB
(
page 3-248).
8
Check Stacker Encode Sensor signal.
Does the voltage across P8302B-13 and
P8302B-12 on the Finisher Main PWB
change when the sensing area is
blocked or opened?
Replace the
Finisher Main
PWB
(
page 3-248).
Replace Stacker
Encode Sensor
(
page 3-142).
9
Check the Elevator Motor.
Run the Service Diagnostics Stacker Motor
Up and Down tests alternately.
Does the Elevator Motor operate?
Replace the
Finisher Main
PWB
(
page 3-248).
Go to Step 10.
10
Check the Elevator Motor connection.
Is P/J8305 connected to the Finisher
Main PWB?
Go to Step 12. Connect and go
to Step 11.
11
Print a Test Print.
Does the error still occur?
Go to Step 12. Problem solved.
12
Replace the Elevator Motor.
Print a Test Print.
Does the error still occur?
Replace the
Finisher Main
PWB
(
page 3-248).
Problem solved.
