Envelopes with double-side seams
An envelope with double-side-seam construction (vertical seams at
both ends of the envelope rather than diagonal seams) is more likely
to wrinkle. Make sure 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.
Card stock and heavy media
For optimum performance, do not use paper heavier than 157 g/m
2
(42-pound). 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 to 180 Sheffield.
