Paper Size The paper size in the cassette is detected by the cassette size-sensing
switches (CSW1, 2, and 3) on the cassette size-sensing board. Loading
the cassette will turn the switches on or off as applicable. The CPU on
the DC controller detects the presence of the cassette and its size by this
switch combination.
