8.4.3 Identifying the Paper Size

iR3225 / iR3225N / iR3235 / iR3235N / iR3245 / iR3245N
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 configu-
ration as soon as a cassette is fitted in the machine.

MEMO:
-
SW4 is used to detect the state of the AB/Inch-configuration switch.
- The machine will assume the absence of a cassette if it detects a combination not found in the table. At this time, it does not move up the cassette lifter.
- Since the paper size is not identified, there will be no indication of a paper size on the control panel; when the cassette in question is selected, the machine will
indicate a message prompting the supply of paper.
- If an envelope size is detected, an envelope cassette must be fitted.
