2.6 Printing in Simplex Mode
Printed paper is delivered and stacked either facedown or faceup depending
on the printout position selected (Figure 2–2). When envelope/faceup is
selected, printed paper is delivered faceup to the rear output tray. Although
the rear output tray can be used to stack paper faceup from a cassette, it
is used primarily to stack envelopes, transparencies, labels and heavier
weight (thicker) papers. See Section 2.9 for information about manually
feeding print media.
When duplex/facedown is selected, printed paper is delivered facedown to
the top output tray. Your print job is collated in the correct page order when
it is delivered to the top output tray.
NOTE:
You cannot select the printout delivery (envelope/faceup or
duplex/facedown) through a command from the host computer; positioning
the printout selector is the only way to select the printout delivery for all
modes of operation.

CAUTION: Do not try to change the printout selector while the printer is
printing. Changing the printout selector during printing causes paper jams.
