Step Actions and Questions
Check the Registration Sensor
11
Harness for continuity.
1. Disconnect P/J232 from the Right
Side Harness.
2. Disconnect P/J2322 from the
Registration Sensor.
3. Check continuity between P/J232
<=> P/J2322.
Check the Right Side Harness for
12
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.
13 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?
Check the Registration Sensor signal.
14
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?
1. Check the wiring harness
15
connectors P/J23 and P/J236
between the MCU Board and the
Tray 1 Feed Solenoid.
2. Are the connectors securely
connected?
Check the Right Side Harness for
16
continuity.
1. Disconnect P/J23 from the MCU
Board.
2. Disconnect P/J236 from the Tray 1
Feed Solenoid.
3. Check continuity between P/J23 <=>
P/J236.
