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 shown 
below. The dimensional tolerances are ±0.7mm 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 blank spaces 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 between 60 and 120g/m² (16 to 31.9 
lib/ream) for the cassette and between 60 and 220g/m² (16 to 59 
lib/ream) for the MP tray.
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 s hould 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 0.110mm (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. U. S. Bond Weight (lb) Europe Metric Weight (g/m²)

2-6Paper Handling
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 cut 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 problems 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. When 
paper passes through the fixing unit, it curls upward a little. To produce 
flat printouts, load the paper so that the upward pressure from the 
machine can correct their curling.
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.
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.

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, envelopes, cardstock, 
coated, or thick paper, feed the paper from the MP Tray.
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 fed to the MP Tray. One transparency can be 
loaded at a time.
Transparencies must be able to withstand the heat of fusing during the 
printing process. The recommended transparency product is 3M PP2500 
(Letter, A4).
Transparencies must be placed on the MP tray with the long edge 
towards the printer.
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 to the MP Tray. One label can be loaded at a time.
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.Paper type to be used Paper type to be selected

2-8Paper Handling
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
Up to 10 postcards can be 
loaded at a time. 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.

Paper Handling2-9
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
Up to 5 envelopes can be loaded at a 
time. Envelopes should be fed in the 
face-up position, right edge first.
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 2-6. 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 less envelopes on the MP tray.
• To avoid jams caused by curled envelopes, stack no more than 10 
printed envelopes on the output tray. 
Thick Paper
Fan the stack of paper and align the edges before loading them in the 
MP tray. Align the edges before loading it in the MP tray. Some types of 
paper have rough edges on the back (those are created when the paper 
is cut). In this case, put the paper on a flat place and rub the edges once 
or twice with, for example, a ruler to smooth them. Feeding rough edged 
paper may cause paper jams.
Colored Paper
Colored paper should satisfy the same conditions as white bond paper. 
Refer to  Paper Specifications  on page2-2. In addition, the pigments 
used in the paper must be able to withstand the heat of fusing during the 
printing process (up to 200°C or 392°F).
Note If the thick paper 
jams:
• Load one sheet at 
a time.
• Hold the paper with 
your hands when it 
is being fed.
• Load the paper in 
the MP Tray with 
the leading edge 
raised up a few millimeters as shown in the illustration.

Preprinted Paper
Preprinted paper should satisfy the same conditions as white bond 
paper. Refer to Paper Specifications  on page2-2.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.
Recycled paper
Select recycled paper that meets the same specifications as the white 
bond paper except for whiteness. Refer to  Paper Specifications on 
page 2-2.
Note Before purchasing recycled paper, test a sample on the 
machine and check that the printing quality is satisfactory.
