2. Detecting the Cassette Size
The AB configuration and the Inch configuration are distinguished by the switch (SW654) on
the cassette switching PCB.
The size of the paper inside the cassette is identified with reference to the states (on/off) of
the switches (SW651 through 653) on the cassette size switch PCB.
Table 5-201 shows the combinations used to identify specific paper sizes.
