2.2 Selecting the Right Paper

2.2.2 Paper 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.
