4 1. Reseat Tray 3.
2.Does the error still occur?
Go to step 5. Complete.
5 1. Check the No Paper Actuator.
2.Does the Actuator operate
smoothly?
Go to step 6. Replace the
Tray 3 Feeder
Assembly
(
page 8-107).
6 1. Perform the Tray 3 No Paper test
(page 4-36): Service Mode >
Engine Diag > Sensor Test > Tray 3
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/J421, P/J4212, and P/
J42121 between the No Paper
Sensor and the Tray 3 Feeder Board.
2.Are the connectors securely
connected?
Go to step 8. Reconnect the
connectors.
8 Check the C2 Chute Harness for
continuity.
1.Disconnect P/J421 from the
Optional Feeder Board and P/J4212
from the C2 No Paper Harness.
2.Check continuity between P/J421
<=> P/J4212.
Go to step 9. Replace the
Optional Sheet
Feeder
(
page 8-100).
9 Check the C2 No Paper Harness for
continuity.
1.Disconnect P/J4212 from the C2
Chute Harness and P/J42121 from
the No Paper Sensor.
2.Check continuity between P/J4212
<=> P/J42121.
Go to step 10. Replace the
Tray 3 Feeder
Assembly
(
page 8-107).
10 Check the No Paper Sensor signal.
1.Disconnect P/J421 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J421-3 pin?
Go to step 11. Go to step 12.
11 Check the No Paper Sensor for
operation.
1.Measure the voltage across ground
<=> J421-5 pin.
2.Does the voltage change when the
No Paper Actuator of the No Paper
Sensor is activated?
Go to step 12. Replace the No
