Envelopes

---

Envelopes can be printed from Tray 1 or Tray 2. Select the type of envelope that you are using from the Print dialog box or the printer driver.

In your program, set the margins for the envelope. The following table gives typical address margins for a commercial #10 or DL envelope.

Type of address	Top margin	Left margin
Return address	15 mm (0.6 inch)	15 mm (0.6 inch)
Delivery address	51 mm (2 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 seams meet.

Envelope storage

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

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/m2 (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, stuck together, or otherwise damaged. Never use envelopes that have clasps, snaps, windows, coated linings, self-stick adhesives, or other synthetic materials.
●	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	Minimum	Maximum
Tray 1 or Tray 2	76 x 127 mm (3 x 5 inches)	216 x 356 mm (8.5 x 14 inches)

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 indicated in the following illustration.

1	Acceptable
2	Unacceptable

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

CAUTION	Failure to follow the guidelines above can result in jams.
