Go to the SP5-102-203 (input check SP for the proximity sensor).
Cover the sensor with 10 sheets of plain paper, and then execute SP to confirm if it
becomes "0". (Do not place your hand near the sensor even over the papers when
covering the sensor)
Remove the papers from the sensor and confirm if it becomes "1".
If there is no issue after the confirmation in step 2 and 3, confirm that there are no
possible factors around the machine that may cause the temperature change such as
heater or fan. (Deal with the issue as necessary)
Replace the proximity sensors and proximity sensor board if the abnormal value is
detected after the confirmation in step 2 and 3.
Turn on the main power on and perform step 1, 2, and 3 again.
If SC is not solved, turn the main power off and replace the harness which connects
proximity sensors and proximity sensor board.
If SC is still not solved, there is a possibility that the other parts of the machine such as
