8.5.3 Identifying the Paper Size

/ / / / iR C3380i / iR C3380 / iR C2880i / iR C2880
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.
1. Size switch of AB configuration/Inch configuration
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 configu-
ration as soon as a cassette is fitted in the machine.
