Envelope construction is critical. Envelope fold lines can vary considerably, not only between
manufacturers, but also within a box from the same manufacturer. Successful printing on
envelopes depends upon the quality of the envelopes. When selecting envelopes, consider
the following components:
Weight: The weight of the envelope paper should not exceed 105 g/m
(28 lb) or
jamming might occur.
Construction: Prior to printing, envelopes should lie flat with less than 6 mm (0.25 inch)
curl, and should not contain air.
Condition: Envelopes should not be wrinkled, nicked, or otherwise damaged.
Temperature: You should use envelopes that are compatible with the heat and
pressure of the printer.
Size: You should use only envelopes within the following size ranges.
Minimum: 76 x 127 mm (3 x 5 inches)
Maximum: 216 x 356 mm (8.5 x 14 inches)
Use only tray 1 or the optional envelope feeder to print envelopes.You might experience
some jams when using any media with a length less than 178 mm (7 inches). This might be
caused by paper that has been affected by environmental conditions. For optimum
performance, make sure you are storing and handling the paper correctly (see
paper storage environment
). Choose envelopes in the printer driver (see
Using the printer
Appendix D Media specifications
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. Be sure the seam extends all the
way to the corner of the envelope as illustrated below.
Acceptable envelope construction
Unacceptable envelope construction
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 compatible with the heat and pressure in the printer. The extra flaps and
strips might cause wrinkling, creasing, or even jams and might even damage the fuser.
The following gives typical address margins for a commercial #10 or DL envelope.
Type of address
15 mm (0.6 inch)
15 mm (0.6 inch)
51 mm (2.0 inches)
89 mm (3.5 inches)
For the best print quality, position margins no closer than 15 mm (0.6 inch) from the edges
of the envelope. Avoid printing over the area where the envelope's seams meet.
Proper storage of envelopes helps contribute to print quality. Envelopes should be stored
flat. If air is trapped in an envelope, creating an air bubble, then the envelope might wrinkle
