Replacing the Fitted Plug (for UK Only)
Important
The mains lead for this machine is fitted with a standard (BS 1363) 13 amp
plug and has a 13 amp fuse. When you change or examine the fuse, you
must re-fit the correct 13 amp fuse. You then need to replace the fuse cover.
If you have lost the fuse cover, do not use the plug until you have another fuse
cover.
Please contact the people from you purchased the machine.
The 13 amp plug is the most widely used type in the UK and should be
suitable. However, some buildings (mainly old ones) do not have normal 13
amp plug sockets. You need to buy a suitable plug adaptor. Do not remove
the moulded plug.
Warning
If you cut off the moulded plug, get rid of it straight away.
You cannot rewire the plug and you may receive an electric shock if you
plug it into a socket.
Important warning:
You must earth this machine.
The wires in the mains lead have the following color code:
• Green and Yellow: Earth
• Blue: Neutral
•Brown: Live
If the wires in the mains lead do not match the colors marked in your plug, do
the following:
You must connect the green and yellow wire to the pin marked by the letter
“E” or by the safety ‘Earth symbol’ or colored green and yellow or green.
You must connect the blue wire to the pin which is marked with the letter “N”
or colored black.
You must connect the brown wire to the pin which is marked with the letter “L”
or colored red.
You must have a 13 amp fuse in the plug, adaptor, or at the distribution board.

media
This chapter introduces you how select and load print media for your
machine.
This chapter includes:
• Selecting print media
• Verifying the output location
• Loading paper
• Printing on special print materials
• Setting the paper size and type
Selecting print media
You can print on a variety of print media, such as plain paper, envelopes,
and labels. Always use print media that meet the guidelines for use with
your machine. 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 on 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.
Caution
Using print media that does not meet these specifications may
cause problems, requiring repairs. Such repairs are not covered
by Samsung’s warranty or service agreements.
Note
• 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
When selecting or loading paper, envelopes, or other print materials,
keep these guidelines in mind:
• Always use print media that conform with the specifications listed on
page 4.2.
• 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 machines.
• Avoid using the following 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 machine.
• 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.
• Store unused print media at temperatures between 15 °C and 30 °C.
The relative humidity should be between 10% and 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 media types one sheet at a time through the multi-
purpose tray to avoid paper jams.
• To prevent print media, such as label sheets, from sticking together,
remove them as they print out.

Guidelines for special print media
Media type Guidelines
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/m2 or jamming may
occur.
- Construction: Prior to printing, envelopes
should lie flat with less than 6 mm 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 machine 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.
• Envelopes with a peel-off adhesive strip or with
more than one flap that folds over to seal must
use adhesives compatible with the machine’s
fusing temperature for 0.1 second. Check your
machine’s specification to view the fusing
temperature, see page 10.1. 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 from the edges of the
envelope.
• Avoid printing over the area where the
envelope’s seams meet.
Acceptable
Unacceptable
Labels • To avoid damaging the machine, use only labels
designed for use in laser machines.
• When selecting labels, consider the following
factors:
- Adhesives: The adhesive material should be
stable at your machine’s fusing temperature.
Check your machine’s specification to view the
fusing temperature, see page 10.1.
- 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 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 machine components.
• Do not run a sheet of labels through the machine
more than once. The adhesive backing is
designed for only a single pass through the
machine.
• Do not use labels that are separating from the
backing sheet or are wrinkled, bubbled, or
otherwise damaged.
Card stock or
custom-sized
materials
• Do not print on media smaller than 98 mm wide
or 148 mm long.
• In the software application, set margins at least
6.4 mm away from the edges of the material.
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 10.1.
• 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.
Media type Guidelines

4.4 <
Selecting and loading print media>
Verifying the output location
The machine has the output tray that collects paper face-down, in correct
order.
Loading paper
In the tray
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 150 sheets of 75 g/m2 (20 lb
bond) plain paper.
You can purchase an optional tray and attach it below the standard tray
to load an additional 250 sheets of paper. (See "Accessories" on
page 8.1.)
Loading paper in the tray 1 or optional tray
1Pull the tray out of the machine.
Note
• If you continuously print many pages, the surface of the output
tray may become hot. Be careful not to touch the surface, and
especially keep children away from the surface.
• The output tray can hold up to 100 sheets of paper. Remove
the pages so that the tray is not overloaded.
2Open the paper cover, and enlarge the tray by adjusting the paper
width guide.
3Flex the paper sheets back and forth to separate the pages and then
dan them while holding one edge. Tap the edges of the stack on a
flat surface to even it up.

Printing on preprinted paper
• Preprinted paper is paper that has some type of printing on it before it
is sent through the machine (paper that has a preprinted logo at the
top of the page, for example).
• Letterhead must be printed with heat-resistant ink that will not melt,
vaporize, or release hazardous emissions when subjected to the
machine’s fusing temperature of 180 °C (356 °F) for 0.1 seconds.
• Ink on letterhead must be non-flammable and should not adversely
affect machine rollers.
• Forms and letterhead should be sealed in 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 of preprinted paper, reducing the print quality.
To print on preprinted paper:
1Squeeze the paper length guide and slide it out to its full length.
2Load letterhead in the tray, with the print side up and the top and

Cleaning your machine
During the printing process, particles of paper, toner, and dust can
accumulate inside the machine. Over time, this build-up can cause print
quality problems such as toner specks or smearing. Your machine has a
cleaning mode that can correct and prevent these types of problems.
Cleaning the outside
Clean the machine cabinet with a soft, lint-free cloth. You can dampen the
cloth slightly with water, but be careful not to let any water drip onto or into
the machine.
Caution
Cleaning the machine cabinet with cleaning materials that
contain large amounts of alcohol, solvent, or other strong
substances can discolor or damage the cabinet.

Maintaining the cartridge
Toner cartridge storage
To get the most from the toner cartridge, keep the following guidelines in
mind:
• Do not remove the toner cartridge from its package until ready for use.
• Do not refill the toner cartridge. The machine warranty does not
cover damage caused by using a refilled cartridge.
• Store toner cartridges in the same environment as your machine.
• To prevent damage to the toner cartridge, do not expose it to light for
more than a few minutes.
Expected cartridge life
The life of a toner cartridge depends on the amount of toner that your print
jobs require. When printing text at 5% coverage, the toner cartridges last
an average of 4,000 pages for black and white printing and 2,000 pages
for each color printing.
Redistributing toner
When a print cartridge is low on toner, faded or light areas may appear.
It is also possible that colored images may be printed with incorrect colors
due to flawed mixing of toner colors when one of the colored print
cartridges is low on toner. The Smart Panel program window appears on
the computer telling you which color cartridge is low on toner. Also, when
the toner LED, on the control panel, indicating each individual print
cartridge according to its color, blinks, the print cartridge is low.
The machine is able to continue to print using the current toner cartridge
until the Smart Panel program window appears on the computer telling
you to replace the cartridge.
You may be able to temporarily improve print quality by redistributing the
toner.
To redistribute the toner:
1Open the front cover.
2Holding the corresponding toner cartridge’s handle, rotate it
counter-clockwise, and pull it out to remove from the machine.
3Holding the toner cartridge, shake thoroughly it from side to side to
redistribute the toner.

Maintenance>
4Grasp the toner cartridge and align it with the corresponding slot
inside the machine. Insert it back into its slot until it clicks into place,
and rotate the toner cartridge clockwise.
Note
If toner gets on your clothing, wipe it off with a dry cloth and
wash it in cold water. Hot water sets toner into fabric.
5Close the front cover. Make sure that the cover is securely closed.
Replacing the toner cartridge
The machine uses four colors and has a different toner cartridge for each
one: yellow (Y), magenta (M), cyan (C), and black (K).
When the toner colors LED, on the control panel, indicating each
individual toner cartridge according to its color, lights, and the Status LED
lights red, the machine cartridge is totally exhausted. Your machine stops
printing.
Also, the Smart Panel program window appears on the computer telling
you to replace the cartridge.
At this stage, the toner cartridge needs to be replaced. Check the type of
toner cartridge for your machine. (See "Supplies" on page 8.1.)
Note
The print quality may get poor if the refilled toner
cartridge is installed, since its characteristicsGmay
significantly differ from the genuineU

Condition Suggested solutions
Background scatter
Background scatter results from bits of toner
randomly distributed on the printed page.
• The paper may be too damp. Try printing
with a different batch of paper. Do not open
packages of paper until necessary so that
the paper does not absorb too much
moisture.
• If background scatter occurs on an
envelope, change the printing layout to
avoid printing over areas that have
overlapping seams on the reverse side.
Printing on seams can cause problems.
• If background scatter covers the entire
surface area of a printed page, adjust the
print resolution through your software
application or in printer properties.
Misformed
characters
• If characters are improperly formed and
producing hollow images, the paper stock
may be too slick. Try different paper. (See
"Specifications on print media" on page 4.2.)
• If characters are improperly formed and
producing a wavy effect, the scanner unit
may need service. Contact a service
representative.
Page skew
• Ensure that the paper is loaded properly.
• Check the paper type and quality. (See
"Specifications on print media" on page 4.2.)
• Ensure that the paper or other material is
loaded correctly and the guides are not too
tight or too loose against the paper stack.
Curl or wave
• Ensure that the paper is loaded properly.
• Check the paper type and quality. Both high
temperature and humidity can cause paper
curl. (See "Specifications on print media" on
page 4.2.)
• Turn the stack of paper over in the tray. Also
try rotating the paper 180° in the tray.
