Error Messages and Codes
15 Check the Fuser signal.
1.Disconnect P/J17 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J17-1 pin on MCU Board?
Go to step 16. Replace the
MCU Board
(page 8-88).
16 Check the Exit Sensor for signal.
1.Measure the voltage across ground
<=> P/J17-3 on the MCU Board.
2.Does the voltage change when the
Actuator of the Exit Sensor is
activated?
Replace the
MCU Board
(page 8-88).
Replace the
Fuser
(page 8-12).
17 1. Check the wiring harness
connectors P/J23, P/J232, and P/
J2322 between the MCU Board and
the Registration Sensor.
2.Are the connectors securely
connected?
Go to step 18. Reconnect the
connectors.
18 Check the Registration Sensor
Harness for continuity.
1.Disconnect P/J2322 from the
Registration Sensor.
2.Disconnect P/J232 from the Right
Side Harness.
3.Check continuity between P/J232
<=> P/J2322.
Go to step 19. Replace the
Registration
Sensor
Harness.
19 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.
Go to step 20. Replace the
Right Side
Harness.
20 Check the Registration Sensor for
continuity.
1.Disconnect P/J23 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J23-8 pin on the MCU Board?
Go to step 21. Replace the
MCU Board
(page 8-88).
21 Check the Registration Sensor signal.
1.Measure the voltage across ground
<=> J23-10 pin on the MCU Board.
2.Does the voltage change when the
Actuator of the Registration Sensor
is activated?
Replace the
MCU Board
(page 8-88).
Replace the
Feeder Unit
(page 8-47).
