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: l Weight: See "Paper specifications" on page 47 for supported envelope weight. l Construction: Prior to printing, envelopes should lay flat with less than 6 mm (0.25 inches) curl and should not contain air. (Envelopes that trap air may cause problems.) l Condition: Make sure envelopes are not wrinkled, nicked, or otherwise damaged. l Sizes in optional Tray 1: See "Supported sizes of paper for input and output" on page 48 for supported paper sizes. 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 of the printer. The extra flaps and strips 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 may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope. Envelope storage Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored flat. If air is trapped in an envelope creating an air bubble, then the envelope may wrinkle during printing. Paper specifications

Envelopes
Note
To print envelopes, use optional Tray 1 and print them either to the face-down bin or to the face-up bin.
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:
l
Weight:
See “Paper specifications” on page 47 for supported envelope weight.
l
Construction:
Prior to printing, envelopes should lay flat with less than 6 mm (0.25 inches) curl and
should not contain air. (Envelopes that trap air may cause problems.)
l
Condition:
Make sure envelopes are not wrinkled, nicked, or otherwise damaged.
l
Sizes in optional Tray 1:
See “Supported sizes of paper for input and output” on page 48 for supported
paper sizes.
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 of the printer. The extra flaps and strips 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 may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope.
Envelope storage
Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored flat. If air is
trapped in an envelope creating an air bubble, then the envelope may wrinkle during printing.
