<Function>
This function allows you to check whether the 20 sensors work correctly.
<Operating Procedure>
(1) Press the [3] and [2] keys in this order in the initial stage of the maintenance mode.
The machine beeps 1100 Hz and 400 Hz tones cyclically through the following volumes
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
(or rear) sensor or the registration sensor (s), open the front cover or the document
cover, remove the toner cartridge, jam paper at the paper outlet, insert paper from the
manual feeder, and load a recording paper tray, etc.
