NOTE Choose transparencies in the printer driver. Card stock and heavy media You can print many types of card stock from the paper 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. For optimum printer performance, do not use paper heavier than 157g/m2 (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. Card stock construction ● Smoothness: 135-157g/m2 (36-42 lb) card stock should have a smoothness rating of 100-180 Sheffield. 60-135g/m2 (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 in.) of curl. ● Condition: Make sure that the card stock is not wrinkled, nicked, or otherwise damaged. ● Sizes: Only use card stock within the following size ranges: ● Minimum: 76 x 127 mm (3 x 5 in.) ● Maximum: 216 x 356 mm (8.5 x 14.0 in.) Card stock guidelines Set margins at least 2 mm (0.08 in.) away from the edges. Letterhead and preprinted forms Many manufacturers now offer premium paper advertised as laser-compatible or laser-guaranteed. Some of the rougher surface finishes, such as cockle, laid, or linen, might require the special fuser modes that are available on some printer models in order to achieve adequate toner adhesion. NOTE Some page-to-page variation is normal when printing with laser printers. This variation cannot be observed when printing on plain paper. However, this variation is obvious when printing on preprinted forms because the lines and boxes are already placed on the page. To avoid problems when using preprinted forms, embossed paper, and letterhead, observe the following guidelines: ● Avoid using low-temperature inks (the kind used with some types of thermography). ● Use preprinted forms and letterhead paper that have been printed by offset lithography or engraving.
