Printing on special print media
This section contains guidelines for printing on special print media, which includes
envelopes, letterhead, transparencies, postcards, and heavy paper, and for printing full-
bleed images.
Choosing and printing on envelopes
You can print on envelopes from tray 1, which holds up to 10 envelopes, and send them to
the face-up bin. Many types of envelopes can be printed from tray 1.
Printing performance depends on the construction of the envelope. Always test printing on
a few sample envelopes before purchasing a large quantity.
Envelope construction
Envelope construction is critical. Envelope fold lines can vary considerably, not only
between manufacturers but also within a box from the same manufacturer.
● Construction: Before printing, envelopes should lie flat with less than 6 mm
(0.25 inch) curl and should not contain air. (Envelopes that trap air can cause printing
problems.)
● Condition: Make sure that envelopes are not wrinkled, nicked, or otherwise damaged.
Envelopes with adhesive strips or flaps
Envelopes with a peel-off adhesive strip, or with more than one flap that folds over to seal,
must use adhesives that are compatible with the heat and pressure of the MFP. The extra
flaps might cause wrinkling, creasing, or jams.
Envelopes with double-side seams
Double-side-seam construction has vertical seams at both ends of the envelope rather
than diagonal seams. This style might be more likely to wrinkle. Make sure that the seam
extends all the way to the corner of the envelope.
Envelope storage
Proper storage of envelopes contributes to good print quality. Envelopes should be stored
flat. If air is trapped in an envelope and creates an air bubble, then the envelope might
wrinkle during printing.
Envelope margins
The following table gives typical address margins for a Commercial #10 or DL envelope.
For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges
of the envelope.
Type of address Top margin Left margin
