8.4.3 Identifying the Paper Size

The size of paper inside the cassette is detected by the cassette size dial, and is
communicated to the cassette size detection PCB.
As may as 15 positions may be detected with reference to the combinations of on and off
states of the array of 4 actuators mounted to the cassette size detection PCB on the printer
side and operating in conjunction with the cassette size dial.
In the absence of a cassette, all 4 actuators are off, causing the machine to assume there is
no cassette.
AB/Inch Switch
The cassette size dial is equipped with a switch operated to change between AB and Inch
configurations; the cassette size detecting switch will detect the configuration as soon as a
cassette is fitted in the machine.
