2.2 Selecting the Right Paper2-52.2.2 Paper propertiesSmoothnessPaper should have a smooth, uncoated surface. Paper with a rough or sandy surface cancause gaps in printouts. However, paper with surfaces that are too smooth may causemultiple-sheet feeding and fogging problems (fogging is a gray background effect).Basis weightsBasis weight is the weight in pounds of 500 sheets (called a ream) of paper cut to the basicsize, which is 17 × 22 inches. The number of sheets in a ream and the basic paper sizerelating to basis weights depend on paper classifications. In the metric system, the basisweight is expressed in grams per square meter (g/m²).Paper that is too heavy or too light may cause misfeeds, jams, and premature wear of printerparts. Uneven weight of paper can cause multiple-sheet feeding, print defects, poor tonerfusing, blurring, and other print quality problems. The recommended basis weights for thisprinter are between 64 and 90 g/m² (17 to 24 lb per ream).When you use paper with basis weights of 135 to 220 g/m², use the face-up tray forhigh-quality printouts.Paper Weight Equivalence TableThe paper weight is listed with expression in U.S. bond weight (lb) and European metric(g/m²).
