4 Reseat Tray 2. Does the error still
occur?
Check the No Paper Actuator. Does the
5
Actuator operate smoothly?
6 Perform the Tray 3 No Paper test
(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/J421, P/J4212, and P/J42121
between the No Paper Sensor and the
Tray 3 Feeder Board. Are the
connectors securely connected?
Check the C2 Chute Harness for
8
continuity.
1. Disconnect P/J421 and P/J4212.
2. Check continuity between P/J421
<=> P/J4212.
9 Check the C2 No Paper Harness for
continuity.
1. Disconnect P/J4212 and P/J42121.
2. Check continuity between P/J4212
<=> P/J42121.
Check the No Paper Sensor signal.
10
1. Disconnect P/J421 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J421-3?
Check the No Paper Sensor for
11
operation.
1. Measure the voltage across ground
<=> J421-5.
2. Does the voltage change when the
No Paper Actuator is activated?
