3.1. General guidelines
The duplexer may not be used to print on paper not satisfying the require-
ments below. Also, special types of print media such as overhead projection
(OHP) film, envelopes, adhesive backed labels, and paper containing water-
marks 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.
Note 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 xerographic copiers can also be used with the duplexer and the
printer.
There are three general grades of paper: economy, standard, and premium.
The most significant 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 output will reflect.
Differences between paper from different suppliers can also affect the
duplexer's performance. 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 traditional 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-qual-
ity 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:
