Paper Delivery Choices
Your laser printer can deliver paper facedown on top of the printer
or faceup into the face-up output tray. The advantage of printing
facedown is that when the printed stack is turned over, the pages
are collated from first page to last. On the other hand, the face-up
output tray gives you immediate viewing of your printed output.
The faceup method of delivery is necessary for printing on media
that require a straight-through paper path, such as envelopes, labels,
heavy paper, and overhead transparencies.
To select faceup printing, simply move the paper path selector
(located on the left side of the printer) to the down position. Also be
sure that the face-up output tray is installed. (See Chapter 1 for
details.) To select face-down printing, move the paper path selector
to the up position.
