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. The printer's maximum temperature is
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.
Cardstock and heavy media
You can print many types of cardstock from the media input trays, including index cards and postcards.
Some cardstock 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.
Cardstock construction
● Smoothness: The 135-157 g/m 2 (36-42 lb) cardstock should have a smoothness rating of
100-180 Sheffield; 60-135 g/m 2 (16-36 lb) cardstock should have a smoothness rating of
100-250 Sheffield.
● Construction: Cardstock should lie flat with less than 5 mm (0.2 inches) of curl.
