for testing the speaker. To stop beeping, press the [OK] button.
If the sensing status are as listed below, the LCD will show the following:
"C1P1C2P2T2T3BC**", "TNMPNTRMRSPOCV" and "DFDRDLDSFCFH****"
(which can be switched by pressing the [Start] button for machines.)
Given below is the relationship among the LCD indication, sensor names and sensor
status.
(2) Change the detecting conditions to check that the indication on the LCD changes
according to the sensor states. For instance, insert paper through the document front
