Error Messages and Codes
7 Check the Fuser signal.
1.Disconnect P/J17 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J17-1 pin?
Go to step 8. Replace the
MCU Board
(
page 8-86).
8 Check the Exit Sensor for signal.
1.Measure the voltage across ground
<=> P/J17-3 pin.
2.Does the voltage change when the
Actuator of the Exit Sensor is
activated?
Replace the
MCU Board
(
page 8-86).
Replace the
Fuser
(
page 8-11).
9 1.Perform the Registration Sensor
test (page 4-30): Service Mode >
Engine Diag > Sensor Test > Regi
Sensor.
2.Does the number on the Control
Panel increase by 1 when the
Actuator of the Registration Sensor
is activated?
Go to step 15. Go to step 10.
10 1.Check the wiring harness
connectors P/J29, P/J292, and P/
J2922 between the MCU Board and
the Registration Sensor.
2.Are the connectors securely
connected?
Go to step 11. Reconnect the
connectors.
11 Check the Registration Sensor
Harness for continuity.
1.Disconnect P/J292 from the Right
Side Harness and P/J2922 from the
Regi Sensor.
2.Check continuity between P/J292
<=> P/J2922.
Go to step 12. Replace the
Registration
Sensor
Harness.
12 Check the Right Side Harness for
continuity.
1.Disconnect P/J29 from the MCU
Board and P/J292 from the Regi
Sensor Harness.
2.Check continuity between P/J29 <=>
P/J292.
Go to step 13. Replace the
Right Side
Harness.
13 Check the Registration Sensor for
continuity.
1.Disconnect P/J29 from the MCU
Board.
2.Is there +3.3 V across ground <=>
J29-8 pin?
Go to step 14. Replace the
MCU Board
(
page 8-86).
