Envelopes with double-side seams
An envelope with 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. Make sure that the seam extends all
the way to the corner of the envelope as shown in the following illustration:

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 in the printer: 200° C (392° F). The extra flaps and
strips might cause wrinkling, creasing, or jams.
Envelope storage
Proper storage of envelopes contributes to good print quality. You should store envelopes flat. If air is
trapped in an envelope, creating an air bubble, the envelope might wrinkle during printing.
Card stock and heavy media
You can print many types of card stock from the paper input tray, including index cards and postcards.
Some card stock performs better than others because its construction is better suited for feeding through
a laser printer.
For optimum printer performance, do not use paper heavier than 157 g/m 2 (42 lb). Paper that is too
heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print quality, or
excessive mechanical wear.
NOTE You might be able to print on heavier paper if you do not fill the input tray to capacity
and if you use paper with a smoothness rating of 100-180 Sheffield.
