<Function>
This function checks whether sensors work normally.
<Operating Procedure>
(1) Enter [3] and [2] in the initial stage of the maintenance mode.
The machine sounds 1,100 Hz and 400 Hz tones cyclically through the following
volumes for testing the speaker.
Note To stop tones from the speaker, press [SET] or [Menu].
If the sensing statuses are as defined below, the LCD shows the 1st sensor group
"DFDRCVRSCCP1****".
(2) Press [Mono Start] to switch to the next sensor group.
If asterisks ("**") appear on the LCD, it means that the corresponding sensor does not
exist on the model.
Given below is the relationship between the LCD indication, sensor name and sensor
status.
*1 For ADF models only
*2 For Ink Cartridge models and MFC-T800W only
*3 For Ink Cartridge models only
