2.5 Printout Selector
The printout selector (located on the rear paper tray) allows you to choose
the output tray for the type of jobs you are printing. You can place the
selector in one of two positions as shown in Figure 2–1.

MLO-005121 (Figure 2-6; 16 picas)
The duplex/facedown position sends one-sided or two-sided output to the
top output tray. The envelope/faceup position sends one-sided output
and envelopes to the rear output tray. Only the rear output tray can
accommodate envelopes. (See Section 2.6.1 and Section 2.6.2.)
In the duplex/facedown position, the rear output tray is used as a paper
reversing area before the paper is fed back into the printer. The printout
selector must be in the duplex/facedown position to print in duplex mode,
and paper is always delivered to the top output tray (see Section 2.7).
