Duplex Printing Mode

The printing operation flow in duplex printing mode is as follows. Initially, the first
sheet is fed and page 2 of the document is printed on one side of the sheet. The first
printed sheet is temporarily transferred to the duplexer. Then the printer feeds the
second sheet on which page 4 is printed on one side. After page 4 has printed, the
first sheet held in the duplexer is again sent to the printer’s transfer unit for printing
of page 1. This completes printing of the first sheet and this is output. Following
this and while the second sheet, on which page 4 has been printed on one side, is
retained on standby in the duplexer, the printer feeds the third sheet and prints page
6 on this sheet. The operation is now repeated as described above to perform the
duplex printing.

Duplex printing from the Multi-Purpose Tray

In first mode, be sure to set the MP tray to the same paper size, paper type and feed
direction as set for the current cassette. If the paper size, type or feed direction
differs, a paper jam may result. Also note that it is not possible to select the multi­purpose tray as the current cassette and perform duplex printing. We therefore
recommended that duplex printing be performed from the paper cassette.

Note In the case of an FS-7000, duplex printing is not possible from the

printer’s MP (multi-purpose) tray, the optional envelope feeder (EF-

1), or optional universal feeder (UF-1). If duplex printing is at­tempted from these paper sources, the mode is automatically
canceled and the printed paper is output from the face-up tray.
When the duplex printing mode is set to off, paper can also be
output from the face-down tray. However, when feeding paper from
the envelope feeder, output is through the face-up tray.

Paper Selection

Although the page printer is designed for printing on standard dry PPC photocopier
copy paper (standard paper), it can print on various types of paper that conform to
the specifications given in this chapter. For details on paper which can be used,
also refer to the printer’s User’s Manual.

Select paper carefully as using paper inappropriate for the printer may result in
paper jams or wrinkling of output paper. Low-quality paper may reduce printing
quality, not only wasting paper but possibly leading to damage to the printer. It is
possible to achieve efficient printing with few problems and minimize the risk of
printer damage or wear by following the precautions listed below.

Usable Paper

Be sure to use copy paper (standard paper) used in standard dry PPC photocopiers.

Note Some recylced paper does not meet the necessary specifications

(Table 1) for use in this printer due to conditions such as stored
water and pulp content. Before purchasing recycled paper, test a
sample on the printer and check that printing quality is satisfactory.
Be sure to select a brand of recycled paper which offers good
printing quality and does not contain excessive paper dust.

There are differences in grade between each paper manufacturer, and these
differences can affect printer operations. Satisfactory printing results cannot be
obtained through the use of poor-quality paper. Even inexpensive paper may turn
out to be uneconomical from a results standpoint if its quality is inappropriate for
the printer.

20

Basic Paper Specifications

The following table summarizes the basic paper specifications.

Table 1. Basic Paper Specifications

English

Item Specification

Weight 60 to 90 g/m
Thickness 0.086 to 0.110 mm
Dimensional accuracy ±0.7 mm
Squareness of corners 90° ±0.2°
Moisture content 4% to 6%
Pulp content 80% or more

2

Note When performing duplex printing on paper larger than A4, espe-

cially with thin paper weighing less than 65 g/m2, the edges may
become slightly dirty. Use standard paper weighing more than
70 g/m2.

Kyocera bears absolutely no responsibility for accidents resulting
from the use of inappropriate paper which does not meet the
specifications listed above. Consult with your Kyocera dealer before
purchasing any specially treated paper or special application paper.

Selecting the Right Paper

High quality printing is possible when using paper that conforms to the conditions
in Table 1. Points that must be taken into consideration when selecting paper for
duplex printing are discussed below.

Deutsch

FrançaisItalianoEspañol

Condition of the Paper

Avoid using paper that is folded at the corners, curled, dirty, torn, has rough edges,
fuzzy fibers, a rough surface or is easily torn.

Use of paper in these conditions can lead to illegible printing, misfeeding, and
paper jams, and can shorten the life of the printer. Select paper which has as
smooth and even a surface as possible. Note that the use of paper with a surface
coating or other surface treatement may damage the drum or fuser unit.

21

Composition

Do not use paper that has been coated or surface-treated and contains plastic or
carbon. The heat of fusing can cause such paper to give off harmful fumes, and
may damage the drum.
Bond paper should contain at least 80% pulp. Not more than 20% of the total paper
content should consist of cotton or other fibers.

Paper Size

Cassettes and the MP (multi-purpose) tray can handle the paper sizes listed in Table

2. The printer automatically detects the paper size loaded in a cassette.

Table 2. Paper Sizes for Paper Feeding

Paper Size

ISO A3 297 × 420 mm
ISO A4 210 × 297 mm
ISO A5 148 × 210 mm
JIS B4 257 × 364 mm
JIS B5 182 × 257 mm
Ledger 11 × 17 inches
Letter 8.5 × 11 inches
Legal 8.5 × 14 inches

Smoothness

Although it is important to use paper with a smooth and even surface, do not use
paper which has been coated. Paper that is too smooth can cause multiple feeding
and paper jams.

Basis Weight

Basis weight is the weight of a one square meter sheet of paper. Paper that is too
light or too heavy can cause misfeeding, jams, and premature wear of the printer.
Uneven paper weight can cause multiple feeds, print defects, poor toner fusing,
blurring, and other print quality problems. The appropriate paper weight range for
normal paper is 60 to 90 g/m2 (16 to 24 lbs/ream) and 90 to 200 g/m2 (24 to 53 lbs/
ream) for thick paper.

22

Thickness

The paper used with the printer should be neither extremely thick nor extremely
thin. If you are having problems with multiple feeds and paper jams, the paper may
be too thin. The paper may also be too thick if you are having problems with paper
jams. The proper thickness is 0.086 to 0.110 mm (3.4 to 4.3 mils).

Moisture Content

English

Moisture content is defined as the percentage 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 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 the
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 dry, well-ventilated location.

• Keep the paper flat and 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. Keep paper away from boarded or concrete floors during rainy
weather.

• Avoid leaving paper where it is exposed to heat, sunlight, or damp.

Other Paper Properties

Stiffness: Paper that is too limp or too stiff may fold or bend inside the printer,

resulting in a paper jam.
Curl: Most paper has a natural tendency to curl in one direction or the other if it is

stored unwrapped. Paper will curl slightly upward when it passes through the fuser
unit. Load the paper with its natural curl downward so that it will come out flat.
Some paper also has a front and back surface. If this is indicated on the paper’s
packaging, be sure to load the paper into the cassette face down.

Note If curl is large, load the paper into the cassette in such a manner

that the paper’s back surface is facing down.

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.

Quality control: Uneven sheet size, corners that are not square, ragged edges,
welded (uncut) sheets, and crushed edges and corners can cause the printer to
malfunction in various ways. Pay particular attention to these considerations if you
are choosing paper yourself.

Packaging: Select paper that is wrapped by the ream and then placed in a box.
The best wrapping is one whose inner surface is coated to protect against humidity.

Specially treated paper: We recommend that you avoid using paper listed
below which has been specially treated, even if it meets basic specifications. If you
wish to use such paper, test a sample on the printer and check that the printing
quality is satisfactory before purchasing.

• Paper with a glossy finish

• Paper with sections cut out

• Paper which is embossed

• Paper with feed holes in it

• Paper with punch holes in it

24

Special paper

The page printer can use the following types of special paper:

• Colored paper

• Preprinted paper (letter head, etc.)

When using the above types of paper, be sure to use products that are specified for
use with photocopiers and/or page printers.

Since the composition and quality of special paper vary considerably, special paper
is more likely than white bond paper to give trouble during printing. Some special
paper will emit harmful gases during printing. When using a new type of special
paper for the first time, make sure to perform a test first.

English

Deutsch

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

printer and check that the printing quality is satisfactory.

Following are the specifications for special paper.

Colored paper

Colored paper should meet the same specifications as those listed for white bond
paper in Table 1. In addition, the pigments used in the paper must be able to
withstand the heat of fusing during the printing process.

Preprinted paper (letter head, etc.)

When printing on preprinted paper, the preprinted ink must be able to withstand the
heat of fusing during the printing process, and must not be affected by silicone oil.

Do not use paper with any kind of surface treatment.

Note In the duplex printing mode, page 2 is printed first. When using

letter head paper, etc. for duplex printing, it is recommended to
place the paper with the sides reversed in the cassette.
