Paper Grain - Kyocera FS-2020D Operation Manual

Paper Handling
• 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.

Paper Grain

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 grain paper can cause feeding problems in the machine. All paper
used in the machine should be long grain.
Other Paper Properties
Porosity: Indicates the density of paper fiber.
Stiffness: Limp paper may buckle in the machine, resulting in paper
jams.
Curl: Most paper naturally tends to curl one way if left unpacked. When
paper passes through the fixing unit, it curls upward a little. To produce
flat printouts, load the paper so that the upward pressure from the
machine can correct their curling.
Electrostatic discharge: During the printing process the paper is
electrostatically charged to attract the toner. The paper must be able to
release this charge so that printed sheets do not cling together in the
Output Tray.
Whiteness: The contrast of the printed page depends on the whiteness
of the paper. Whiter paper provides a sharper, brighter appearance.
Quality control: Uneven sheet size, corners that are not square, ragged
edges, welded (uncut) sheets, and crushed edges and corners can
cause the machine to malfunction in various ways. A quality paper
supplier should take considerable care to ensure that these problems do
not occur.
Packaging: Paper should be packed in a sturdy carton to protect it from
damage during transport. Quality paper obtained from a reputable
supplier is usually correctly packaged.
