Print media guidelinesStoring print mediaIdentifying print media sources and specificationsPrint media is paper, card stock, transparencies, labels, and envelopes. Your printer provides high qualityprinting on a variety of print media. Selecting the appropriate print media for your printer helps you avoidprinting problems. This chapter provides information on how to help you make print media selections, how tocare for the print media, and how to load it in the standard tray or optional trays.PaperFor the best print quality, use 75 g/m2 (20 lb) xerographic, grain long paper. Try a sample of any paper youare considering using with the printer before buying large quantities.When loading paper, note the recommended print side on the paper package, and load paper accordingly.See Loading print media in standard and optional trays and Using and loading the multipurpose feeder fordetailed loading instructions.Paper characteristicsThe following paper characteristics affect print quality and reliability. We recommend that you follow theseguidelines when evaluating new paper stock.WeightThe printer can automatically feed paper weights from 60 to 135 g/m2 (16 to 36 lb bond) grain long. Paperlighter than 60 g/m2 (16 lb) might not be stiff enough to feed properly, causing jams. For best performance,use 75 g/m2 (20 lb bond) grain long paper. To use paper narrower than 182 x 257 mm (7.2 x 10.1 in.), werecommend that the weight be greater than or equal to 90 g/m2 (24 lb bond).CurlCurl is the tendency of print media to curve at its edges. Excessive curl can cause paper feeding problems.Curl usually occurs after the paper passes through the printer, where it is exposed to high temperatures.Storing paper unwrapped in humid conditions, even in the paper tray, can contribute to paper curling prior toprinting and can cause feeding problems, also.SmoothnessThe degree of smoothness of paper directly affects print quality. If the paper is too rough, the toner does not
