Actuator: Plastic tabs on the
side of a cassette tray
actuate leaf springs, which
press microswitches on the
sheet feeder controller
board.
Note: The sheet feeder uses
a 500-sheet universal
cassette. As with the upper
250-sheet universal
cassette, the tabs are set
manually by adjusting a
selection dial on the cassette.
