Smoothness
The paper should have a smooth, uncoated surface. Paper with a rough
or sandy surface can cause voids in the printed output. Paper that is too
smooth can cause multiple feeding and fogging problems. (Fogging is a
gray background effect.)

Basis Weight

Basis weight is the weight of paper expressed in grams per square meter
(g/m²). Paper that is too heavy or too light may cause feed errors or paper
jams as well as premature wear of the product. Uneven weight of paper,
namely uneven paper thickness may cause multiple-sheet feeding or
print quality problems such as blurring because of poor toner fusing.

Paper Weight Equivalence Table

The paper weight is listed in pounds (lb) and metric grams per square
meter (g/m²). The shaded part indicates the standard weight.

Thickness
The paper used with the machine should be neither extremely thick nor
extremely thin. If you are having problems with paper jams, multiple
feeds, and faint printing, the paper you are using may be too thin. If you
are having problems with paper jams and blurred printing the paper may
be too thick.

Moisture Content

Moisture content is defined as the percent ratio of moisture to the dry
mass of the paper. Moisture can affect the paper's appearance, feed
ability, curl, electrostatic properties, and toner fusing characteristics.
