2 Check connectors P/J23 and P/J234
between the MCU Board and the No
Paper Sensor.
Are the connectors secure?
Go to step 3. Reconnect the
connectors.
3 Check Left Side Harness continuity.
Disconnect P/J23 from the MCU
Board and P/J234 from the No
Paper Sensor.
Is the harness damaged?
Repair or
replace the
harness
(PL10.4.18).
Go to step 4.
4 Check for +3.3 V at J23 on the MCU
Board.
