Understanding print media guidelines Selecting print media Selecting the appropriate print media for the printer helps you avoid printing problems. The following sections contain guidelines for choosing the correct print media for the printer : • Paper • Transparencies • Envelopes • Labels • Card stock Paper To ensure the best print quality and feed reliability, use 75 g/m2 (20 lb) xerographic, grain long paper. Business papers designed for general business use may also provide acceptable print quality. Note: Certain paper types will not print at maximum speed. Always print several samples before buying large quantities of any type of print media. When choosing print media, consider the weight, fiber content, and color. The laser printing process heats paper to high temperatures of 210°C (410°F) for non-MICR applications. Use only paper able to withstand these temperatures without discoloring, bleeding, or releasing hazardous emissions. Check with the manufacturer or vendor to determine whether the paper chosen is acceptable for laser printers. When loading paper, note the recommended print side on the paper package, and load paper accordingly. For detailed tray loading instructions, see the following: • Loading the 250-sheet tray on page18 • Loading the manual feeder on page23 Paper characteristics The following paper characteristics affect print quality and reliability. It is recommended that these guidelines are followed when evaluating new paper stock. For detailed information, see the Card Stock & Label Guide available on the Lexmark Web site at www.lexmark.com/ publications. Weight The printer can automatically feed paper weights from 60 to 9 0 g/m2 (16 to 2 4 lb bond) grain long in the integrated and optional trays and paper weights from 60 to 16 3 g/m2 (16 to 4 3 lb bond) grain long in the manual feeder. Paper lighter than 60g/m 2 (16lb) might not be stiff enough to feed properly, causing jams. For best performance, use 7 5 g/m2 (20 lb bond) grain long paper. To use paper narrower than 182x257 mm (7.2x10.1in.), it is recommended that the weight be equal to 90g/m 2 (24lb bond). Curl Curl is the tendency of media to curve at its edges. Excessive curl can cause paper feeding problems. Curl can occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper unwrapped in hot, humid, cold, and dry conditions, even in the trays, can contribute to paper curling prior to printing and can cause feeding problems.
