Chapter 5 Paper Selection
5-2
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.
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 cor-
ners 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.
Thickness (Caliper)
Thick paper is referred to as high-caliper paper and thin paper as
low-caliper paper. The paper used with the printer should be nei-
ther extremely thick nor extremely thin. If you are having prob-
lems 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.
The proper thickness is 0.086 to 0.110 mm (3.4 to 4.3 mils).
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 appear-
ance, feedability, curl, electrostatic properties, and toner fusing
characteristics.
The moisture content of the paper varies with the relative humid-
ity in the room. When the relative humidity is high and the paper
absorbs moisture, the paper edges expand, becoming wavy in
appearance. When the relative humidity is low and the paper los-
es moisture, the edges shrink and tighten, and print contrast may
suffer.
