Chapter 3 Paper specifications
3-1 DU-25
3.1. General guidelines
The duplexer may not be used to print on paper not satisfying the requirements below.
Also, special types of print media such as overhead projection (OHP) film, envelopes,
adhesive backed labels, and paper containing watermarks must not be used with duplex
printing.
These types can result in jams, misfeeds, and paper waste, and in extreme cases can
damage the duplexer.
Kyocera assumes no liability for problems that occur when paper not satisfying
these requirements is used with the duplexer.
Selection of the right paper is important. The wrong paper can result in jams, misfeeds,
curl, poor print quality, and paper waste, and in extreme cases can damage the duplexer
and the printer. The guidelines given below will increase the productivity of your office by
ensuring efficient, trouble-free printing and reducing wear and tear on the duplexer and
the printer.

3.1.1. Paper availability
Most types of paper are compatible with a variety of machines. Paper intended for xero-
graphic copiers can also be used with the duplexer and the printer.
There are three general grades of paper: economy, standard, and premium. The most sig-
nificant difference between grades is the ease with which they pass through the printer.
This is affected by the smoothness, size, and moisture content of the paper, and the way
in which the paper is cut. The higher the grade of paper you use, the less risk there will
be of paper jam and other problems, and the higher the level of quality your printed out-
put will reflect.
Differences between paper from different suppliers can also affect the duplexer's perfor-
mance. A high-quality printer cannot produce high-quality results when the wrong paper
is used. Low-priced paper is not economical in the long run if causes printing problems.
Paper in each grade is available in a range of basic weights (defined later). The tradi-
tional standard weights are 19, 20, and 24 pounds (70 g/m2 to 90 g/m2).

3.1.2. Selecting the right paper
Printer printing is a process involving laser light, electrostatic discharge, toner, and heat.
In addition, as the paper passes through the printer it undergoes considerable sliding,
bending, and twisting motions. A high-quality printing paper matching the requirements
withstands all these stresses, enabling the duplexer and the printer to turn out clean,
crisp printed copy consistently.
Remember that all paper is not the same. Some of the factors to consider when selecting
paper for duplex printing are as follows:
