Recycled Media
Choose recycled media that meets the same specifications as
standard paper (see “Supported Media Weights and Sizes for Input
Trays” earlier in this chapter). HP recommends that recycled media
contain no more than five percent ground wood.
Envelopes
Envelopes can only be printed from tray 1. The weight of the envelope
paper should not exceed 24 lb (90 g/m 2 ) bond; otherwise, jamming
might occur. For more information on printing envelopes, see “Printing
Envelopes from Tray 1” later in this chapter.

Envelopes should lie flat, with less than 0.25 inches (6.35 mm)
curl.
Output envelopes to the left (face-up) output bin rather than to the
top (face-down) output bin to reduce curl.
The optional multi-bin mailbox does not support envelopes except
in its left (face-up) output bin.
Do not use envelopes with windows or clasps.
Make sure envelopes are not wrinkled, nicked, or otherwise
damaged.
Envelopes with a peel-off adhesive strip or with more than one
flap must use adhesives compatible with the printer's fusing
temperatures (approximately 374° F, or 190° C). Extra flaps or
strips can result in wrinkling or creasing, and can cause jamming.
All folds must be well scored and sharply creased.
Envelopes must be tightly constructed and should not contain air.
Envelopes that contain air may wrinkle as they pass through the
printer.
