8.4.5 Identifying the Size of Paper (cassette 3/4)
0009-3177
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.

8.4.6 Markings on the Width Guide Rail
0009-3179
The width guide rail mounted inside the cassette is provided with paper size detecting holes identified by means of markings from A through M.
If the user reports skew movement, for instance, ask him/her to communicate the marking so that you will know if the paper width is correctly set.
(The purpose of these markings is not disclosed to the user.)
