General Guidelines
The machine is designed to print on standard copier paper (the type used 
in ordinary dry copier machines), but it can also accept a variety of other 
types of paper within the limits specified below.
Selection of the right paper is important. Using the wrong paper can result 
in paper jams, curling, poor print quality, and paper waste, and in extreme 
cases can damage the machine. The guidelines given below will increase 
the productivity of your office by  ensuring efficient, trouble-free printing 
and reducing wear and tear on the machine.
Paper Availability
Most types of paper are compatible with a variety of machines. Paper 
intended for xerographic copiers can also be used with the machine.
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 machine. 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 jams 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 
machine’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 it causes printing problems.
Paper in each grade is available in a range of basis weights (defined 
later). The traditional standard weights are 60 to 120 g/m² (16 to 32 
pounds).

Selecting the Right Paper
This section describes the guidelines for selecting paper.
Condition
Avoid using paper that is bent at the edges, curled, dirty, torn, embossed, 
or contaminated with lint, clay, or paper shreds.
Use of paper in these conditions can lead to illegible printing and paper 
jams, and can shorten the life of the machine. In particular, avoid using 
paper with a surface coating or other surface treatment. Paper should 
have as smooth and even a surface as possible.
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.
Paper Sizes
Cassettes  and the MP tray  are available for the paper sizes listed in the 
table below. For details, including the paper sizes for the paper feeder 
(Optional paper feeder PF-520, PF-530) refer to  Cassette (1 to 4) Size 
(Setting the cassette paper size) on page 4-31 .
The dimensional tolerances are ±0.7 mm (±0.0276 inches) for the length 
and width. The angle at the corners must be 90° ±0.2°.

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 can cause multiple feeding and fogging problems. (Fogging is a 
gray background effect.)
Basis Weight
Basis weight is the weight of paper expressed in grams per square meter 
(g/m²). Paper that is too heavy or too light may cause feed errors or paper 
jams as well as premature wear of the product. Uneven weight of paper, 
namely uneven paper thickness may cause multiple-sheet feeding or 
print quality problems such as blurring because of poor toner fusing.
The recommended basis weight is:
Cassette: 60 to 163 g/m
2
MP tray: 60 to 220 g/m2
PF-520 (optional): 60 to 163 g/m2
PF-530 (optional): 60 to 220 g/m2
Paper Weight Equivalence Table
The paper weight is listed in pounds
 (lb) and metric grams per square 
meter (g/m²). The shaded part indicates the standard weight.
Thickness
The paper used with the machine should be neither extremely thick nor 
extremely thin. If you are having problems with paper jams, multiple 
feeds, and faint printing, the paper you are using may be too thin. If you

are having problems with paper jams and blurred printing the paper may 
be too thick. The correct thickness is 0.086 to 0.110 mm (3.4 to 4.3 mils).
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, feed 
ability, 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 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 jams and alignment anomalies. The 
moisture content of the paper should be 4 to 6 %.
To ensure correct 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. Re-wrap 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 machine 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 cu t 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 pr oblems in the machine. All paper 
used in the machine should be long grain.
Other Paper Properties
Porosity : Indicates the density of paper fiber.
Stiffness : Limp paper may buckle in the machine, resulting in paper 
jams.
Curl : Most paper naturally tends to curl one way if left unpacked. 
Electrostatic discharge : 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, brighter appearance.
Quality control : Uneven sheet size, corners that are not square, ragged 
edges, welded (uncut) sheets, and crushed edges and corners can cause 
the machine to malfunction in various ways. A quality paper supplier 
should take considerable care to ensure that these problems do not 
occur.
Note  When using coated paper, be aware that the sheets will 
stick together in a very humid environment.

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 correctly packaged.
Note  You might see the printer emitting steam in the area around 
the top tray if you use damp paper, but it is safe to continue 
printing.

Special Paper
The following types of special paper can be used:
Use paper that is sold specifically for use with copiers or printers (heat-
fusing type). When using transparencies, labels, thin paper, envelopes, 
postcards, or thick paper, feed the paper from the  MP tray. For details, 
refer to  Paper Source (Selecting the paper feed source) on page 4-37. 
Since the composition and quality of special paper vary considerably, 
special paper is more likely than  white bond paper to give trouble during 
printing. No liability will be assumed if moisture and so forth given off 
during printing on special paper causes harm to the machine or operator.
Transparency
Transparencies must be able to withstand the heat of fusing during the 
printing process. The recommended transparency product is 3M CG3700 
(Letter, A4).
The table below lists the specifications for transparency:

							3-9Handling Paper
To prevent printing problems, feed transparencies into the printer one 
sheet at a time from the 
MP tray. Always load the transparencies vertically 
(with the long edge towards the printer).
If the transparencies have rough edges on the back, it may cause a paper 
jam. Remove the rough edges, reverse the sides or feed the sheet from 
the opposite edge.
When unloading transparencies (e.g., for clearing jams), hold them 
carefully by the edges to avoid leaving fingerprints on them.
Labels
Labels must be fed from the  MP tray or optional paper feeder PF-530.
The basic rule for printing on adhesive labels is that the adhesive must 
never come into contact with any part of the machine. Adhesive paper 
sticking to the drum or rollers will damage the machine.
Label paper has a structure comprising of three layers, as shown in the 
diagram. The top sheet is printed on. The adhesive layer consists of 
pressure-sensitive adhesives. The carrier sheet (also called the linear or 
backing sheet) holds the labels until used. Due to the complexity of its 
composition, adhesive-backed label paper is particularly likely to give 
printing problems.
Adhesive label paper must be entirely covered by its top sheet, with no 
spaces between the individual labels. Labels with spaces in between are 
liable to peel off, causing serious paper jam problems.
Some label paper is manufactured with an extra margin of top sheet 
around the edge. Do not remove the extra top sheet from the carrier sheet 
until after printing is finished.
The table below lists the specifications for adhesive label paper.

Postcards
Fan the stack of postcards and align the edges before loading them in the 
MP tray. Make sure the postcards you are going to set are not curled. 
Feeding curled postcards may cause paper jams.
Some postcards have rough edges on the back (those are created when 
the paper is cut). In this case, put the postcards on a flat place and rub 
the edges with, for example, a ruler to smooth them.
Envelopes
Envelopes should always be fed from the MP tray, with the print-side up. 
Envelopes must be fed from the MP tray or optional paper feeder PF-530.
Since the composition of an envelope is more complex than that of 
ordinary paper, it is not always possible to ensure consistent printing 
quality over the entire envelope surface.
Normally, envelopes have a diagonal grain direction. Refer to  Paper 
Grain on page 3-6 . This direction can easily cause wrinkles and creases 
when envelopes pass through the printer. Before purchasing envelopes, 
make a test print to check whether the printer accepts the envelope. 
• Do not use envelopes that have an encapsulated liquid adhesive.
• Avoid a long printing session for envelopes only. Extended envelope  printing can cause premature printer wear.
• If jams occur, try setting a lesser number of envelopes on the MP tray.
• To avoid jams caused by curled envelopes, stack no more than 10  printed envelopes on the top tray.
