HP LaserJet 3055 - Manual (Page 49)

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 all-in-one: 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 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. The HP LaserJet 3390/3392 all-in-one is designed to accommodate card
stock by opening the rear output door to use the straight-through output path.
For optimum performance, do not use paper heavier than 157 g/m 2 (42 lb). Paper that is too heavy
might cause misfeeds, stacking problems, 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.
Card stock construction
● Smoothness: 135-157 g/m 2 (36-42 lb) card stock should have a smoothness rating of
100-180 Sheffield. 60-135 g/m 2 (16-36 lb) card stock should have a smoothness rating of
100-250 Sheffield.
● Construction: Card stock should lie flat with less than 5 mm (0.2 inch) of curl.
● Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged.
Card stock guidelines
Set margins at least 2 mm (0.08 inch) away from the edges.
