The following are default sizes the machine will assume when U1 through U4 are detected:
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.
