8.4.3 Detecting the Level of Paper
0010-8202
The machine indicates the level of paper inside the deck and the cassette in four readings (including No
Paper) on the control panel.
T-8-7
In the case of the deck right/left, two sensors are used to detect the position of the deck, and combinations
of the states of the sensors (on/off) are used to find out the level of paper.
For the absence of paper, an exclusive sensor is used.
F-8-15
T-8-8
In the case of cassette 3/4, the resistance of the variable resistor operating in conjunction with the move-
ment of the lifter drive shaft is used to find out the level of paper.
