Paper Composition
Use paper made from 100% chemical wood pulp. Paper that contains mechanically-
pulped wood or cotton is not recommended due to natural impurities, such as CaCO

Do not use coated paper containing material that will melt, vaporize, offset, discolor,
or release hazardous emissions when exposed to high temperatures.

Paper Cut
Paper cut is another significant factor affecting printer performance. The cut sheet is
produced by cutting a larger stack of paper. If a dull cutter is used, the paper will have
ragged edges, or what is called a “burr.” This burr can cause such problems as paper
jam, multiple feed, and large amounts of paper dust. Refer to

Paper Friction
The frictional properties of paper are very important for reliable paper picking.
Improper friction properties can cause poor pick up and multi-sheet feeding. High
quality xerographic paper has uniform friction. Refer to
