Smoothness; Basis Weight; Moisture Content; Paper Storage - Kyocera ECOSYS P3060dn Service Manual

command of the PRESCRIBE command language to tell the printer the size of the paper or envelope. Refer to the
printer's Prescribe II Command reference in the CD-ROM supplied with the printer.

(2-3) 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 back-
ground effect.)

(2-4) Basis weight

Basis weight is the weight of a standard quantity of paper. In the traditional system the standard quantity is a ream consist-
ing 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 bulk paper feeder and 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 200 g/m

(2-5) 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
appearance, feedability, 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
paper loses moisture, the edges shrink and tighten, and print contrast may suffer.
Wavy or tight edges can cause misfeeding and alignment anomalies. The moisture content of the paper should be 4% to
6%.
To ensure the proper 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. Rewrap 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 printer for 48 hours before use.
Avoid leaving paper where it is exposed to heat, sunlight, or damp.

(3) Paper storage

When the bulk paper feeder is not to be used for a long time of period, the paper must be removed from the bulk paper
feeder and wrapped in moisture-proof paper for storage.
