Chapter 5 Paper Selection

Wavy or tight edges can cause misfeeding and alignment anom-

alies. 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.

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 printer. All paper used in the printer should be long grain.

Other Paper Properties

Porosity:

Refers to the density of the paper structure; that is,

how openly or compactly the fibers are bonded.

Stiffness: Limp paper can buckle inside the printer, while paper

that is too stiff may bind. Either way the result is a paper jam.

Curl: Most paper has a natural tendency to curl in one direction.

The paper should be loaded so that the natural curl is downward,

to counteract the upward curl imparted by the printer. Printed

sheets will then come out flat. Most paper also has a top and bot-

tom surface. Loading instructions are usually given on the paper

package.

If the paper is considerably curled in one direction, e.g. when the

paper was used to print on one side, try to roll the paper in the

opposite direction to counteract the curl. Printed sheets will then

come out flat.

Electrostatic properties: 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, bright-

er appearance.

Quality control: Uneven sheet size, corners that are not

square, ragged edges, welded (uncut) sheets, and crushed edg-

es and corners can cause the printer 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 pro-

tect it from damage during transport. Quality paper obtained

from a reputable supplier is usually properly packaged.

This section explains printing on special paper. The page printer

can use the following types of special paper. In this case, set the

media type according to the table below.

When using the above types of paper, be sure to use products

that are specified for use with photocopiers and/or page printers.

Feed paper other than colored paper or preprinted paper from

the MP (multi-purpose) tray. Use paper that is sold specifically

for use with copiers (heat-fusing type). Label paper and enve-

lopes should not be placed in the cassette.

Since the composition and quality of special paper vary consid-

erably, special paper is more likely than white bond paper to give

trouble during printing. No liability will be assumed if moisture,

etc., given off in printing on special paper causes harm to the

machine or operator.

Before purchasing any type of special paper, test a sample on

the printer and check that print quality is satisfactory.

Specifications for each type of special paper are given below.

Transparency must be able to withstand the heat of fusing during

the printing process. It should satisfy the conditions given in the

table below.

If transparency jams frequently, pull the top of the sheet very

gently as it leaves the printer.
