Envelopes

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. Many envelope manufacturers are now making envelopes optimized for laser printers.

●Weight: The weight of the envelope paper should be 75 to 105 g/m2 (20 to 28 lb) or jamming might result.

●Construction: Before printing, envelopes should lie flat with less than 6 mm

(0.25 inch) curl, and should not contain air. (Envelopes that trap air might cause problems.)

●Condition: Make sure that envelopes are not wrinkled, nicked, or otherwise damaged.

●Sizes in tray 1: Use standard and custom sizes from 76 by 127 mm (3 by 5 inches) to 216 by 356 mm (8.5 by 14 inches).

●Sizes in the optional envelope feeder: Standard sizes from

Monarch (98 by 191 mm, or 3.9 by 7.5 inches) to B5 (ISO) (176 by 250 mm, or 6.9 by 9.8 inches).

If you do not have an optional envelope feeder, always print envelopes from tray 1. If envelopes curl or jam, try opening the rear output bin.

CAUTION	Do not duplex envelopes. Damage to the printer might result.
	Do not send envelopes to the stacker or stapler/stacker. Damage to the stacker or stapler/stacker
	might result.

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 unless properly constructed. Be sure the seam extends all the way to the corner of the envelope.

Envelopes with adhesive strips or flaps

Envelopes that are use 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 jams.
