4-1-2 Paper feeding mechanism

When a paper feed start signal is received from the engine board of the printer, the paper
feed clutch 1 turns on to rotate the pickup roller 2 and feed roller 3, to start the paper
feed operation. At this point, multiple paper feeding is prevented by the retard pulley 4. The
paper feed motor 5 then conveys the paper through the conveying roller 6 and feed pulley
7 into the printer by rotating the conveying roller 6. The paper feed sensor 8 detects
paper jams.

4-2-2 Operation of circuit board (1) Paper feeder board

The paper feeder board serially communicates with the engine board of the printer and the
paper feeder board of the lower paper feeder to exchange control signals.
Upon reception of a paper feed start signal from the engine board of the printer, CPU IC3
controls the paper feed operation by operating the paper feed motor and paper feed clutch.
The motor drive circuit consists mainly of motor driver IC5. It drives the paper feed motor
based on the control signals (PFM, PWM) from CPU IC3.
The reset circuit consists mainly of reset IC1. It monitors the 5 V DC supply voltage. When
the power is turned on or when the power supply becomes low, it outputs a RESET signal to
CPU IC3, to prevent system malfunction or runaway.

7-1 General guidelines

The paper feeder 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 printing with the paper feeder.

These types can result in jams, misfeeds, and paper waste, and in extreme cases can damage the
paper feeder.

NOTE Kyocera mita assumes no liability for problems that occur when paper not satisfying

these requirements is used with the paper feeder.

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 paper feeder 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 paper feeder and the printer.

7-1-1 Paper availability

Most types of paper are compatible with a variety of machines. Paper intended for xerographic
copiers can also be used with the paper feeder 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 paper feeder's performance.
A high-quality printer cannot produce high-quality results when the wrong paper is used. Low­priced 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 16, 20, and 28 pounds (60 g/m2 to 105 g/m2).

7-3

PF-60

7-1-2 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 paper feeder 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 is as
following in the next section.

PF-60

7-4

7-2 Paper specifications

The following table summarizes the basic paper specifications that should be applied to the paper
used with the paper feeder. Details are given following the table.

Table 7-2-1 Specifications

Item Specification

Weight 60 to 105 g/m2 (16 to 28 lbs./ream)
Thickness 0.086 to 0.110 mm (3.4 to 4.3 mils)
Dimensional accuracy ±0.7 mm (±0.0276 inches)
Squareness 90° ±0.2°
Moisture content 4 to 6 %
Direction of grain Long grain
Pulp content 80 % or more

7-2-1 Points of consideration

The following section provides general information which should be considered when selecting
paper for using with the paper feeder.

(1) Condition of the paper

Avoid using paper that is bent at edges, curled, dirty, torn, or contaminated with lint, clay, or paper
shreds.
Used of paper in these conditions can lead to illegible printing, misfeeding, and paper jams, and can
shorten the life of the paper feeder and the printer. In particular, avoid using paper with a surface
coating or other surface treatment. The paper should have as smooth and even a surface as possible.

(2) 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.
Bond paper should contain at least 80% pulp. Not more than 20% of the total paper content should
consist of cotton or other fibers.

7-5

PF-60

(3) Paper size

The paper feeder is usable with the paper sizes as tabled below.

Table 7-2-2 Paper size

Paper size Dimension

ISO A4 210 × 297 mm
JIS B5 182 × 257 mm
ISO A5 148 × 210 mm
Letter 8-1/2 × 11 inches
Legal 8-1/2 × 14 inches

(4) 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 background effect.)

(5) Basis weight

Paper that is too light or too heavy can cause misfeeding, jams, and premature wear of the 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 105 g/m2 (16 to 28 Ibs/
ream).

(6) Thickness (Caliper)

Thick paper is referred to as high-caliper paper and thin paper as low-caliper paper . The paper used
with the paper feeder should be neither extremely thick nor extremely thin. If you are having problems
with paper jams, multiple feeds, and faint printing, the paper may be too thin. If you are having
problems with paper jams, and blurred printing the paper may be too thick. The proper thickness is

0.086 to 0.110 mm (3.4 to 4.3 mils).

(7) 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 is
appearance. When the relative humidity is low and paper loses moisture, the edges shrink and
tighten, and print contrast may suffer.

PF-60

7-6

Wavy or tight edges can cause misfeeding and alignment anomalies.
The moisture content of the paper should be 4 % to 6 %.
T o 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 head, sunlight, or damp.

(8) Paper grain

When paper is manufactured, it is cut into sheets with the gain running parallel to the length
(long grain) of parallel to width (short grain).
Short grain paper can cause feeding problems in the paper feeder and the printer . All paper used
in the paper feeder and the printer should be long grain.

7-2-2 Other paper properties

(1) Porosity

Refers to the density of the paper structure; that is, to how openly or compactly the fibers are
bonded.

(2) Stiffness

Limp paper can buckle inside the paper feeder and the printer, while paper that is too stiff may
bind. Either way the result is a paper jam.

(3) 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 bottom surface. Loading instructions are usually
given on the paper package.

(4) 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.

(5) Whiteness

The contrast of the printed page depends on the whiteness of the paper. Whiter paper provides a
sharper, brighter appearance.

(6) Quality control

Uneven sheet size, corners that are not square, ragged edges, welded (uncut) sheets, and crushed
edged and corners can cause the paper feeder and the printer and the printer to malfunction in
various ways. A quality paper supplier should take considerable care to ensure that these problems
do not occur.

(7) Packaging

Paper should be packed in a sturdy carton to protect it from damage during transport. Quality paper
obtained from a reputable supplier is usually properly packaged.

7-2-3 Special paper

The following types of special paper can be used:

Colored paper
Preprinted paper

Use paper that is sold specifically for use with copiers (heat-fusing type).
Since the composition and quality of special paper very considerably, 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.

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

and the printer and check that printing quality is satisfactory.

Specifications for each type of special paper are given on next page.

(1) Colored paper

Colored paper should satisfy the same conditions as white bond paper, listed in used in the paper
must be able to withstand the heat of fusing during the printing process (up to 200 °C or 392 °F).

(2) Preprinted paper

Preprinted paper should have a bond paper base. 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, such as the type of paper commonly used for
calendars.
