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.
The correct thickness is 0.086 to 0.110mm (3.4 to 4.3 mils).
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.
The moisture content of the paper varies with the relative humidity 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 loses moisture, the edges shrink and tighten,
and print contrast may suffer.
Wavy or tight edges can cause jams and alignment anomalies. The
moisture content of the paper should be 4 to 6 %.
To ensure correct moisture content, it is important to store the paper in a
controlled environment. Some tips on moisture control are:
• Store paper in a cool, dry location.
• Keep the paper in its wrapping as long as possible. Re-wrap paper
that is not in use.
• Store paper in its original carton. Place a pallet etc. under the carton
to separate it from the floor.
• After removing paper from storage, let it stand in the same room as
the machine for 48 hours before use.
• Avoid leaving paper where it is exposed to heat, sunlight, or damp.
When paper is manufactured, it is cut into sheets with the grain running
parallel to the length (long grain) or parallel to the width (short grain). Short
