Chapter 2 Paper Selection
2-2
Composition
Do not use paper that has been coated or surface-treated and
contains plastic or carbon. The heat of fusing can cause such
paper to give off harmful fumes. Such paper may cause dam-
age to the drum.
Bond paper should contain at least 80 % pulp. Not more than
20 % of the total paper content should consist of cotton or
other fibers.
Paper Size
Cassettes and an MP tray are available for the paper sizes
listed in the table above. The dimensional tolerances are ±0.7
mm (±0.0276 inches) for the length and width. The angle at
the corners must be 90° ±0.2°.
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, however, can cause multiple
feeding and fogging problems. (Fogging is a gray background
effect.)
Basis Weight
Basis weight is the weight of a standard quantity of paper. In
the traditional system, the standard quantity is a ream
consisting of 500 sheets measuring 17
× 22 inches each. In the
metric system the standard quantity is 1 square meter.
Paper that is too light or too heavy can cause misfeeding,
jams, and premature wear of the printer. Uneven paper
weight can cause multiple feeds, print defects, poor toner
fusing, blurring, and other print quality problems. The proper
weight is 60 to 105 g/m
2
for the paper cassette, and 60 to 200
g/m
2
for the MP tray.
