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 extra flaps and strips might cause wrinkling, creasing, or jams. Envelope Margins The following table gives typical address margins for a Commercial #10 or DL envelope. Table 1-12. Envelope Margins Type of Address Top Margin Left Margin Return Address 0.6 in (15 mm) 0.6 in (15 mm) Delivery Address 2 in (51 mm) 3.5 in (89 mm) Note For the best print quality, position margins no closer than 0.6 in (15 mm) from the edges of the envelope. 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, 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/m2) in Tray 1 or 28 lb (105 g/m2) 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. 1-20 Printer Description EN
