Step Actions and Questions
1. Reseat Tray 2.
4
2. Does the error still occur when
printing?
1. Check the No Paper Actuator.
5
2. Does the Actuator operate
smoothly?
6 1. Perform the Tray 2 No Paper test
(page 4-51): Service Mode
Printer Diag >
Sensor Test >
2. Does the number on the Control
Panel increase by 1 every time the
Actuator is activated?
7 1. Check the wiring harness
connectors P/J23, P/J232, and P/
J2321 between the No Paper Sensor
and the MCU Board.
2. Are the connectors securely
connected?
8 Check the Right Side Harness for
continuity.
1. Disconnect P/J23 from the MCU
Board.
2. Disconnect P/J232 from the
Registration Sensor Harness.
3. Check continuity between P/J23 <=>
P/J232.
Check the Registration Sensor
9
Harness for continuity.
1. Disconnect P/J232 from the Right
Side Harness.
2. Disconnect P/J2321 from the No
Paper Sensor.
3. Check continuity between P/J232
<=> P/J2321.
Check the No Paper Sensor signal.

1. Disconnect P/J23 from the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-5 pin on the MCU Board?
11 Check the No Paper Sensor for
operation.
1. Measure the voltage across ground
<=> J23-7 on the MCU Board.
2. Does the voltage change when the
No Paper Sensor is activated?
Yes
