2.9.1 Manually Feeding Paper, Labels, and Transparencies
Use the following procedure to manually feed paper, labels, and
transparencies. Refer to Chapter 5 for the specifications required for print
media. Be sure the printer is set up to print on the media size you are
using — either through the paper (size) feature in the INITIAL Menu, or
by using commands from the host computer — before feeding media (see
Section 2.9).
NOTE:
You can use the rear output tray or the top output tray when
manually feeding paper. You must use the rear output tray when feeding
labels or transparencies to prevent excessive curl.
1. Set the printout selector to the envelope/faceup position.
