16 Print Media Guidelines Print media can be paper, labels, envelopes, and coated paper among others. Your printer provides high-quality printing on a variety of print media. Selecting the appropriate print media for your printer helps avoid printing troubles. This section describes selecting print media, caring for print media, and loading the print media in Multipurpose Feeder (MPF) or Priority Sheet Inserter (PSI). NOTE: The images used in this manual are those of the Dell™ C1765nfw Color Multifunction Printer unless otherwise mentioned. Paper For the best print quality in color, use 75 g/m2 (20 lb) xerographic, grain long paper. For the best print quality in black and white, use 90 g/m2 (24 lb) xerographic, grain long paper. Before buying large quantities of any print media, it is recommended that you try a sample first. When loading paper, identify the recommended print side on the paper package, and load the paper accordingly. See "Loading Print Media in the Multipurpose Feeder (MPF)" on page 211 and "Loading Print Media in the Priority Sheet Inserter (PSI)" on page 219 for detailed loading instructions. Paper Characteristics The following paper characteristics affect print quality and reliability. It is recommended that you follow these guidelines when evaluating new paper stock. Weight Both MPF and PSI automatically feed paper whose weights range from 60 to 163 g/m2 (16 to 44 lb bond) grain long. Paper lighter than 60 g/m2 (16 lb) may not feed properly, and could cause paper jams. For best performance, use 75 g/m2 (20 lb bond) grain long paper. Curl Curl 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, even in the feeder, can contribute to paper curling prior to printing and cause feeding problems regardless of humidity. When printing on curled paper, straighten the paper and then insert it into the MPF or PSI. Smoothness The degree of paper smoothness directly affects print quality. If the paper is too rough, the toner does not fuse to the paper properly, resulting in poor print quality. If the paper is too smooth, it can cause paper feeding problems. Smoothness between 150 and 250 Sheffield points produces the best print quality. Moisture Content The amount of moisture in the paper affects both print quality and the ability of the printer to feed the paper properly. Leave the paper in its original packaging until you are ready to use it. This limits the exposure of the paper to moisture changes that can degrade its performance. Grain Direction Grain refers to the alignment of the paper fibers in a sheet of paper. Grain is either grain long, running the length of the paper, or grain short, running the width of the paper. For 60 to 135 g/m2 (16 to 36 lb bond) paper, grain long fibers are recommended. For paper heavier than 135 g/m2 (36 lb bond), grain short is preferred. Print Media Guidelines 203
