Step Actions and Questions
4 Reseat Tray 2. Does the error still
occur?
Check the No Paper Actuator. Does the
5
Actuator operate smoothly?
Perform the Tray 2 No Paper test
6
(page 4-37): Service Mode
Diag > Sensor Test
Does the number on the Control Panel
increase by 1 every time the Actuator
is activated?
Check the wiring harness connectors
7
P/J23, P/J232, and P/J2321 between
the No Paper Sensor and the MCU
Board. Are the connectors securely
connected?
Check the Right Side Harness for
8
continuity.
1. Disconnect P/J23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
9 Check the Registration Sensor
Harness for continuity.
1. Disconnect P/J232 and P/J2321.
2. Check continuity between P/J232
<=> P/J2321.
Check the No Paper Sensor signal.

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