2.2.2Paper properties

Smoothness

Paper should have a smooth, uncoated surface. Paper with a rough or sandy surface can cause gaps in printouts. However, paper with surfaces that are too smooth may cause multiple-sheet feeding and fogging problems (fogging is a gray background effect).

Basis weights

Basis weight is the weight in pounds of 500 sheets (called a ream) of paper cut to the basic size, which is 17 × 22 inches. The number of sheets in a ream and the basic paper size relating to basis weights depend on paper classifications. In the metric system, the basis weight 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 printer parts. Uneven weight of paper can cause multiple-sheet feeding, print defects, poor toner fusing, blurring, and other print quality problems. The recommended basis weights for this printer 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 for high-quality printouts.

Paper Weight Equivalence Table

The paper weight is listed with expression in U.S. bond weight (lb) and European metric (g/m²). The shaded point indicates the standard weight.

16	60
17	64
20	75
21	80
22	81
24	90
27	100
