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 90 g/m

2

 (24 lb) or jamming

might occur.

●

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. The fusing temperature of this printer is 210°C (410°F).

●

Size: Use only envelopes that are within the following size ranges.

●

Minimum: 6 x 127 mm (3 x 5 inches)

●

Maximum: 216 x 356 mm (8.5 x 14 inches)

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 shown in the illustration.

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 in the printer. The extra
flaps and strips might cause wrinkling, creasing, or even jams and might damage the fuser.

Select the type of label that you are using from the Print dialog box or the printer driver.

To avoid damaging the printer, use only labels that are recommended for laser printers. To
prevent serious jams, always use tray 1 to print on labels and always use the straight-
through paper path. Never print on the same sheet of labels more than once or print on a
partial sheet of labels.
