Envelope storage and construction
Proper storage of envelopes helps contribute to 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 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
Weight: The weight of the envelope paper should not exceed 90 g/m
Construction: Before 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: Use envelopes that are compatible with the heat and pressure of the printer. This
printer's fusing temperature is 210° C (410° F).
Size: Use only envelopes that are within the following size ranges.
Tray 1 or Tray 2
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.
