8.4.4 Paper Level Detection (cassette 3/4)
0015-4546
iR5065 / iR 5055 / iR5075 / / /
The machine checks the amount of paper remaining based on the reading of a variable resistor that operates in conjunction with the movement of the lifter drive
shaft.

8.4.5 Identifying the Size of Paper (cassette 3/4)

Outline
The machine uses the paper size sensor mounted to the rear of the cassette holder to identify the size of paper inside the cassette.
When the cassette is slid into the cassette holder, the paper size sensor is pushed by the boss on the cassette, permitting the machine to detect the width and the
length of paper. The DC controller PCB identifies the size of the paper with reference to the combination of its width and length, and communicates the result of
identification to the controller unit and the reader unit.
The boss pushing the paper size sensor works in conjunction with the guide plate inside the cassette, and its location is determined when the guide plate is set to
suit a specific paper size.
Identifying the Size Paper
The paper length sensor consists of 2 photointerrupters, and the combination of its 2 outputs is used to find out the length of paper.
The paper width sensor, on the other hand, is a variable resistor, and the machine refers to the reading (resistance) of the sensor to find out the width of paper.
