Error Messages and Codes
6 Perform the Registration Sensor test
(page 4-29): Service Mode > Engine
Diag > Sensor Test > Regi Sensor.
Does the number on the Control Panel
increase by 1 when the Actuator of the
Registration Sensor is activated?
Go to step 12. Go to step 7.
7 Check the wiring harness connectors
P/J23, P/J232, and P/J2322 between
the MCU Board and the Registration
Sensor. Are the connectors securely
connected?
Go to step 8. Reconnect the
connectors. Go
to step 8.
8 Check the Registration Sensor
Harness for continuity.
1. Disconnect P/J232 and P/J2322.
2. Check continuity between P/J232
<=> P/J2322.
Go to step 9. Replace the
Registration
Sensor
Harness.
9 Check the Right Side Harness for
continuity.
1. Disconnect P/J23 and P/J232.
2. Check continuity between P/J23 <=>
P/J232.
Go to step 10. Replace the
Right Side
Harness.
10 Check the Registration Sensor for
continuity.
1. Disconnect P/J23 on the MCU
Board.
2. Is there +3.3 V across ground <=>
J23-8?
Go to step 11. Replace the
MCU Board
(page 8-87).
11 Check the Registration Sensor signal.
1. Measure the voltage across ground
<=> J23-10 on the MCU Board.
2. Does the voltage change when the
Actuator of the Registration Sensor
is activated?
Replace the
MCU Board
(page 8-87).
Replace the
Feeder
(page 8-43).
12 Perform the Tray 3 Paper Size test
(page 4-39): Service Mode > Engine
Diag > Sensor Test > Tray 3 Paper
Size.
Does the Size Switch operate
properly?
Go to step 13. Replace the
Tray 3 Size
Switch
(page 8-105).
13 Check the Rollers for operation. Does
the Rollers rotate smoothly?
Replace the
MCU Board
(page 8-87).
Replace the
Tray 3 Retard
Rollers
(page 8-109).
