Error Messages and Codes
5 1. Check the No Paper Actuator.
2.Does the Actuator operate
smoothly?
Go to step 6. Replace the
Feeder
Assembly
(
page 8-36).
6 1. Perform the Tray 2 No Paper test
(page 4-38): Service Mode >
Engine Diag > Sensor Test > Tray 2
No Paper.
2.Does the number on the Control
Panel increase by 1 every time the
Actuator is activated?
Replace the
MCU Board
(
page 8-86).
Go to step 7.
7 1. Check the wiring harness
connectors P/J29, P/J292, and P/
J2921 between the No Paper Sensor
and the MCU Board.
2.Are the connectors securely
connected?
Go to step 8. Reconnect the
connectors.
Go to step 8.
8 Check the Right Side Harness for
continuity.
1.Disconnect P/J29 from the MCU
Board and P/J292 from the Regi
Sensor Harness.
2.Check continuity between P/J29 <=>
P/J292.
Go to step 9. Replace the
Right Side
Harness.
9 Check the Registration Sensor
Harness for continuity.
1.Disconnect P/J292 from the Right
Side Harness and P/J2921 from the
No Paper Sensor.
2.Check continuity between P/J292
<=> P/J2921.
Go to step 10. Replace the
Registration
Sensor
Harness.
10 Check the No Paper Sensor signal.
1.Disconnect P/J29 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J29-5 pin?
Go to step 11. Replace the
MCU Board
(
page 8-86).
11 Check the No Paper Sensor for
operation.
1.Measure the voltage across ground
<=> J29-7 pin.
2.Does the voltage change when the
No Paper Actuator of the No Paper
Sensor is activated?
Replace the
MCU Board
(
page 8-86).
Replace the No
Paper Sensor
(
page 8-45).
