Envelope Storage Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored flat. If air is trapped in an envelope, creating an air bubble, then the envelope may wrinkle during printing. Card Stock and Heavy Paper Many types of card stock can be printed from Tray 1, 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 53 lb (199 g/m 2 ) in Tray 1 or 28 lb (105 g/m 2 ) in other trays.
Paper that is too heavy might cause misfeeds, stacking problems, paper jams, poor toner fusing, poor print quality, or excessive mechanical wear. Note Printing on heavier paper may be possible if the tray is not filled to capacity, and paper with a smoothness rating of 100-180 Sheffield is used. Card Stock Construction z Smoothness: 36-53 lb (135-199 g/m 2 ) card stock should have a smoothness rating of 100-180 Sheffield. 16-36 lb (60-135 g/m 2 ) card stock should have a smoothness rating of 100-250 Sheffield. z Construction: Card stock should lie flat with less than 0.2 in (5 mm) of curl. z Condition: Make sure card stock is not wrinkled, nicked, or otherwise damaged. z Sizes:
Use only card stock within the following size ranges: • minimum: 3 by 5 in (76 by 127 mm) • maximum: 8.5 by 14 in (216 by 356 millimeters) Note Before loading card stock in Tray 1, make sure it is regular in shape and not damaged. Also, make sure the cards are not stuck together. Card Stock Guidelines z If cards curl or jam, try printing from Tray 1 and opening the rear output bin. z Set margins at least 0.08 in (2 mm) away from the edges of the paper. 1-18 Printer Description EN
