4 Loading print media
This chapter will help you understand the types of paper you can use
with your printer and how to properly load paper in the different paper
trays for the best print quality.
This chapter includes:
•Selecting print media
•Loading paper
•Printing with a prescribed paper size
•Knowing an output location
Selecting print media
You can print on a variety of print media, such as plain paper, envelopes,
labels, and transparencies. Always use print media that meet the
guidelines for use with your printer. Print media that does not meet the
guidelines outlined in this user’s guide may cause the following
problems:
• Poor print quality
• Increased paper jams
• Premature wear output trayn the machine.
Properties, such as weight, composition, grain, and moisture content,
are important factors that affect the machine’s performance and the
output quality. When you choose print materials, consider the following:
• The type, size and weight of the print media for your machine are
described later in this section.
• Desired outcome: The print media you choose should be appropriate
for your project.
• Brightness: Some print media are whiter than others and produce
sharper, more vibrant images.
• Surface smoothness: The smoothness of the print media affects how
crisp the printing looks on the paper.
Notes
• Some print media may meet all of the guidelines in this section
and still not produce satisfactory results. This may be the
result of improper handling, unacceptable temperature and
humidity levels, or other variables over which Samsung has no
control.
• Before purchasing large quantities of print media, ensure that
it meets the requirements specified in this user’s guide.

Guidelines for selecting and storing print media
Guidelines for special print media
When selecting or loading paper, envelopes, or other print media, keep
these guidelines in mind:
• Always use print media that conform with the specifications listed on
the next column.
• Attempting to print on damp, curled, wrinkled, or torn paper can cause
paper jams and poor print quality.
• For the best print quality, use only high quality copier grade paper
specifically recommended for use in laser printers.
• Avoid using the following print media types:
- Paper with embossed lettering, perforations, or a texture that is too
smooth or too rough
- Erasable bond paper
- Multi-paged paper
- Synthetic paper and thermally reactive paper
- Carbonless paper and Tracing paper.
• Use of these types of paper could result in paper jams, chemical
smells, and damage to your printer.
• Store print media in its ream wrapper until you are ready to use it.
Place cartons on pallets or shelves, not on the floor. Do not place
heavy objects on top of the paper, whether it is packaged or
unpackaged. Keep it away from moisture or other conditions that can
cause it to wrinkle or curl.
o
• Store unused print media at temperatures between 15
o
F to 86o F). The relative humidity should be between 10% and
(59
C and 30o C
70%.
• Store unused print media in a moisture-proof wrap, such as a plastic
container or bag, to prevent dust and moisture from contaminating
your paper.
• Load special print media types one sheet at a time through the
manual tray to avoid paper jams.
• To prevent print media, such as transparencies and label sheets, from
sticking together, remove them as they print out.
TypeGuidelines
Envelopes• Successful printing on envelopes depends
upon the quality of the envelopes. When
selecting envelopes, consider the following
factors:
- Weight: The weight of the envelope paper
should not exceed 90 g/m
2
(24 lb) or jamming
may occur.
- Construction: Prior to printing, envelopes
should lie flat with less than 6 mm
(0.25 inches) curl, and should not contain air.
- Condition: Envelopes should not be wrinkled,
nicked, or otherwise damaged.
- Temperature: You should use envelopes that
are compatible with the heat and pressure of
the printer during operation.
• Use only well-constructed envelopes with sharp
and well creased folds.
• Do not use stamped envelopes.
• Do not use envelopes with clasps, snaps,
windows, coated lining, self-adhesive seals, or
other synthetic materials.
• Do not use damaged or poorly made
envelopes.
• Be sure the seam at both ends of the envelope
extends all the way to the corner of the
envelope.
Acceptable
Caution
• If you print 20 envelopes in succession, the surface of the top
cover may become hot. Please exercise caution.
4.3 <
Unacceptable
• Envelopes with a peel-off adhesive strip or with
more than one flap that folds over to seal must
use adhesives compatible with the printer’s
fusing temperature for 0.1 second. Check your
machine’s specification to view the fusing
temperature, see page 11.1. The extra flaps
and strips might cause wrinkling, creasing, or
jams, and may even damage the fuser.
• For the best print quality, position margins no
closer than 15 mm (0.6 inches) from the edges
of the envelope.
• Avoid printing over the area where the
envelope’s seams meet.

TypeGuidelines
TypeGuidelines
Transparencies• To avoid damaging the printer, use only
transparencies designed for use in laser
printers.
• Transparencies used in the printer must be able
to withstand the machine’s fusing temperature.
Check your machine’s specification to view the
fusing temperature, see page 11.1.
• Place them on a flat surface after removing
them from the printer.
• Do not leave them in the paper tray for long
periods of time. Dust and dirt may accumulate
on them, resulting in spotty printing.
• To avoid smudging caused by fingerprints,
handle them carefully.
• To avoid fading, do not expose printed
transparencies to prolonged sunlight.
• Ensure that transparencies are not wrinkled,
curled, or have any torn edges.
Labels• To avoid damaging the printer, use only labels
designed for use in laser printers.
• When selecting labels, consider the following
factors:
- Adhesives: The adhesive material should be
stable at 180° C (356° F), the printer’s fusing
temperature.
- Arrangement: Only use labels with no
exposed backing between them. Labels can
peel off sheets that have spaces between the
labels, causing serious jams.
- Curl: Prior to printing, labels must lie flat with
no more than 13 mm (5 inches) of curl in any
direction.
- Condition: Do not use labels with wrinkles,
bubbles, or other indications of separation.
• Make sure that there is no exposed adhesive
material between labels. Exposed areas can
cause labels to peel off during printing, which
can cause paper jams. Exposed adhesive can
also cause damage to printer components.
• Do not run a sheet of labels through the printer
more than once. The adhesive backing is
designed for only a single pass through the
printer.
• Do not use labels that are separating from the
backing sheet or are wrinkled, bubbled, or
otherwise damaged.
Preprinted
paper
• Letterhead must be printed with heat-resistant
ink that will not melt, vaporize, or release
hazardous emissions when subjected to the
printer’s fusing temperature for 0.1 second.
Check your machine’s specification to view the
fusing temperature, see page 11.1.
• Letterhead ink must be non-flammable and
should not adversely affect printer rollers.
• Forms and letterhead should be sealed in a
moisture-proof wrapping to prevent changes
during storage.
• Before you load preprinted paper, such as
forms and letterhead, verify that the ink on the
paper is dry. During the fusing process, wet ink
can come off preprinted paper, reducing print
quality.
Loading paper
Load the print media you use for the majority of your print jobs in the tray
1. The tray 1 can hold a maximum of 250 sheets of 20 lb plain paper.
You can purchase an optional tray (tray 2) and attach it below the
standard tray to load an additional 250 sheets of paper. For order
information for an optional tray, see 7.1.
The paper level indicator on the front of the tray 1 and the optional tray
2 shows the amount of paper currently left in the tray. When the tray is
empty, the indicator of the bar is completely lowered.
