Error Messages and Codes
4 Reseat Tray 2. Does the error still
occur?
Go to step 5. Complete.
5 Check the No Paper Actuator. Does the
Actuator operate smoothly?
Go to step 6. Replace the
Feeder
(page 8-43).
6 Perform the Tray 2 No Paper test
(page 4-37): Service Mode > Engine
Diag > Sensor Test > Tray 2 No Paper.
Does the number on the Control Panel
increase by 1 every time the Actuator
is activated?
Replace the
MCU Board
(page 8-87).
Go to step 7.
7 Check the wiring harness connectors
P/J23, P/J232, and P/J2321 between
the No Paper Sensor and the MCU
Board. 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/J23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
Go to step 9. Replace the
Right Side
Harness.
9 Check the Registration Sensor
Harness for continuity.
1. Disconnect P/J232 and P/J2321.
2. Check continuity between P/J232
<=> P/J2321.
Go to step 10. Replace the
Registration
Sensor
Harness.
10 Check the No Paper Sensor signal.
1. Disconnect P/J23 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-5?
Go to step 11. Replace the
MCU Board
(page 8-87).
11 Check the No Paper Sensor for
operation.
1. Measure the voltage across ground
<=> J23-7.
2. Does the voltage change when the
No Paper Sensor is activated?
Replace the
MCU Board
(page 8-87).
Replace the No
Paper Sensor
(page 8-48).
