• TCP/IP: Transmission Control Protocol/Internet Protocol
• DHCP: Dynamic Host Configuration Protocol
• BOOTP: Bootstrap Protocol
You need to set up the network protocols on the printer to use it as your
network printer. Protocols can be set up by the following two methods:
Via network administration programs
Configuring TCP/IP
You can configure your printer’s print server settings and manage the
printer via the following programs that came with your printer:
Your printer can be set up with a variety of TCP/IP network information,
such as an IP address, a subnet mask, a gateway, and DNS addresses.
There are several ways in which your printer can be assigned a TCP/IP
address, depending on your network.
• SyncThru™ Web Admin Service: A web-based printer management
solution for network administrators. SyncThru™ Web Admin
Service provides you with an efficient way of managing network
devices and lets you remotely monitor and troubleshoot network
printers from any site with corporate intranet access.
• Static addressing: A TCP/IP address is assigned manually by the
system administrator.
• SyncThru™ Web Service: A web server embedded to your network
print server, which allows you to configure the network parameters
necessary for the printer to connect to various network environments.
• Dynamic addressing via BOOTP/DHCP (default): A TCP/IP address
is assigned automatically by the server.
• SetIP: A utility program allowing you to select a network interface and
manually configure the addresses for use with the TCP/IP protocol.
Note
Before configuring TCP/IP, you need to set the network
protocol to TCP/IP.
For further details, refer to the user’s guide on the network utilities CD
that came with your printer.

5 Loading print media
Selecting print media
This chapter includes:
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:
•
Selecting print media
• Poor print quality
•
Loading paper
• Increased paper jams
•
Selecting an output location
• Premature wear on the printer.
This chapter will help you understand 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.
Properties, such as weight, composition, grain, and moisture content,
are important factors that affect the printer’s performance and the output
quality. When you choose print materials, consider the following:
• Desired outcome: The print media you choose should be appropriate
for your project.
• Size: You can use any size media that fits easily within the paper
adjusters of the paper tray.
• Weight: Your printer supports print media weights as follows:
- 16 to 24 lb (60 to 90 g/m2) bond for the tray 1 and optional tray 2
- 16 to 43 lb (60 to 163 g/m2) bond for the multi-purpose tray
- 20 to 24 lb (75 to 90 g/m2) for the duplex printing (ML-3051ND only)
• 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.
Caution

Guidelines for selecting and storing print media
Guidelines for special print media
When selecting or loading paper, envelopes, or other print materials,
keep these guidelines in mind:
Media type
• Always use print media that conform with the specifications listed on
page 5.3.
• 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 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.
• Store unused print media at temperatures between 15o C and 30o C
(59o F to 86o F). The relative humidity should be between 10% and
70%.
Envelopes
• 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.
Guidelines
• 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 (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
• Load special media types one sheet at a time through the multipurpose tray to avoid paper jams.
• To prevent print media, such as transparencies and label sheets, from
sticking together, remove them as they print out.
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 of 200° C (392° F) for
0.1 second. 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.
5.3

Media type
Guidelines
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 200° C (392° F), the printer’s fusing
temperature.
• 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 200° C (392° 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.
Card stock or
custom-sized
materials
Media type
Preprinted
paper
Guidelines
• 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 of 205° C (400° F)
for 0.1 second.
• 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 page 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.
Full ▲
• Do not print on media smaller than 76 mm
(3 inches) wide or 127 mm (5 inches) long.
• In the software application, set margins at least
6.4 mm (0.25 inches) away from the edges of
the material.
5.4

▲ Empty
Using the tray 1 or the optional tray 2
Press and hold the guide lock, and slide the paper length guide to
locate it in the correct paper size slot.
After inserting paper into the tray, adjust the support guide so that it
lightly touches the paper stack.
Squeeze the paper width guides, as shown and slide them to the
stack of paper until it lightly touches the side of the stack.
Use the print material you use for the majority of your print jobs in the
tray 1. The tray 1 can hold a maximum of 250 sheets of 75 g/m2 paper.
You can purchase an optional tray 2 and attach it below the tray 1 to load
an additional 250 sheets of paper.
To load paper, pull open the tray and load paper with the side to be
printed on face down.
You can load letterhead paper with the design side face down. The top
edge of the sheet with the logo should be placed at the front of the tray.
Notes
• If you experience problems with paper feed, place one sheet
at a time in the multi-purpose tray.
• You can load previously printed paper. The printed side
should be facing up with an uncurled edge at the front. If you
experience problems with paper feed, turn the paper around.
Note that the print quality is not guaranteed.
Changing the size of the paper in the tray 1
To load longer sizes of paper, such as Legal-sized paper, you need to
adjust the paper guides to extend the paper tray.

Notes
• Do not push the paper width guide far enough to cause the
material to warp.
• If you do not adjust the paper width guide, it may cause paper
jams.
Load the paper with the side to be printed on facing up.
Using the multi-purpose tray
The multi-purpose tray can hold special sizes and types of print material,
such as transparencies, postcards, note cards, and envelopes. It is
useful for single page printing on letterhead or colored paper.
Depending on the media type you are using, keep the following
loading guidelines:
To load paper in the multi-purpose tray:
• Envelopes: Flap side down and with the stamp area on the top left
side.
Open the multi-purpose tray and unfold the multi-purpose tray
extension, as shown.
• Transparencies: Print side up and the top with the adhesive strip
entering the printer first.
• Labels: Print side up and top short edge entering the printer first.
• Preprinted paper: Design side up with the top edge toward the
printer.
• Card stock: Print side up and the short edge entering the printer
first.
• Previously printed paper: Previously printed side down with an
uncurled edge toward the printer.
Note
Make sure that you have not loaded too much print material.
The print material buckles if you load a stack that is too deep or
if you push it in too far.
Caution
If you are using paper, flex or fan the edge of the paper stack to
separate the pages before loading.
When you print on special material like envelopes, labels,
transparencies, or cards, the output location should be the
rear cover. Open the rear cover to use it. See page 5.8.
Squeeze the multi-purpose tray paper width guides and adjust
them to the width of the paper. Do not force too much, or the paper
will be bent, which will result in a paper jam or skew.
For transparencies, hold them by the edges and avoid touching the
print side. Oils from your fingers can cause print quality problems.

When you print a document, set the paper source and type in the
software application. See the Software Section.
Squeeze the multi-purpose tray paper width guides and adjust
them to the width of the paper. Do not force too much, or the paper
will be bent, which will result in a paper jam or skew.
When you print a document, set the paper source to Manual Feed
and select the appropriate paper size and type in the software
application. See the Software Section.
Print a document.
For information about setting the paper source and type on the
control panel, see page 2.3.
After printing, fold the multi-purpose tray extension and close the
multi-purpose tray.
Tips on using the multi-purpose tray
• Load only one size of print media at a time in the multi-purpose tray.
• To prevent paper jams, do not add paper when there is still paper in
the multi-purpose tray. This also applies to other types of print media.
• Print media should be loaded face up with the top edge going into the
multi-purpose tray first and be placed in the center of the tray.
• Always load only the print media specified in page 5.1 to avoid paper
jams and print quality problems.
• Flatten any curl on postcards, envelopes, and labels before loading
them into the multi-purpose tray.
• When you print on 76 mm x 127 mm (3 x 5 inches) sized media on
the multi-purpose tray, open the rear cover for straight paper path to
avoid paper jams.
The display shows a message prompting you to load paper and
press Stop (if you use the ML-3050) or OK (if you use the ML3051N or ML-3051ND).
• Make sure to open the rear cover when you print on transparencies. If
not, they may tear while exiting the printer.
Using manual feed mode
The printer picks up the print material and prints. After one page is
printed, the message appears again.
You can manually load a sheet of print material in the multi-purpose tray
if you select Manual Feed in the Source option from the Paper tab when
you change print settings to print a document. See the Software
Section. Manually loading paper can be helpful when you want to check
the print quality after each page is printed.
Note
If you do not press the button, after a pause the printer will
automatically pick the print material.
This loading procedure is almost the same as the procedure for loading
in the multi-purpose tray, except you load paper sheet-by-sheet in the
tray, send print data to print the first page, and press Stop (if you use the
ML-3050) or OK (if you use the ML-3051N or ML-3051ND) on the control
panel to print each following page.
Press Stop or OK.
Insert the next sheet into the multi-purpose tray and press Stop or
OK.
Repeat this step for every page to be printed.
Load the paper with the side to be printed on facing up.
5.7

Printing to the rear cover (Face up)
Selecting an output location
Using the rear cover, paper comes out of the printer face up.
The printer has two output locations; the rear cover (face up) and the
output tray (face down).
Printing from the multi-purpose tray to the rear cover provides a straight
paper path. Using the rear cover might improve the output quality with
special print media.
To use the rear cover, open it by pulling down.
Unfold the duplex guide.
rear cover
output tray
The printer sends output to the output tray by default. To use the output
tray, make sure that the rear cover is closed.
Notes
• If paper coming out of the output tray has problems, such as
excessive curl, try printing to the rear cover.
• To avoid paper jams, do not open or close the rear cover while
the printer is printing.
Printing to the output tray (Face down)
Caution
The output tray collects paper face down, in the order in which the sheets
were printed. The tray should be used for most print jobs.
The fuser area inside the rear cover of your printer becomes
very hot when in use. Take care when you access this area.

8 Maintenance
Cleaning the printer
During the printing process, paper, toner, and dust particles can
accumulate inside the printer. This buildup can cause print quality
problems, such as toner specks or smearing. Your printer has a cleaning
mode that can correct and prevent these types of problems.
This chapter provides information for maintaining your printer and the
toner cartridge, as well as suggestions for high-quality and economical
printing.
This chapter includes:
•

cartridge. Use the handle on the cartridge to avoid touching
this area.
8.1

3
With a dry lint-free cloth, wipe away any dust and spilled toner from
the toner cartridge area and the toner cartridge cavity.
In the ML-3051N and ML-3051ND, this process will produce a page with
toner debris, which should be discarded.
Make sure that the printer is turned on with paper loaded in the tray.
Press Menu until System Setup appears on the bottom line of the
display and press OK.
Press the Scroll buttons until Maintenance appears and press OK.
When Clean Drum appears, press OK.
Or, press the Scroll buttons until Clean Drum or Clean Fuser

Maintaining the toner cartridge
Caution
While cleaning the inside of the printer, be careful not to touch
the transfer roller, located underneath the toner cartridge. Oil
from your fingers can cause print scan quality problems.
Toner cartridge storage
To get the most from the toner cartridge, keep the following guidelines in
mind:
Locate the long strip of glass (LSU) inside the top of the cartridge
compartment, and gently swab the glass to see if dirt turns the
white cotton black.
• Do not remove the toner cartridge from its package until ready for
use.
• Do not refill the toner cartridge. The printer warranty does not cover
damage caused by using a refilled cartridge.
• Store toner cartridge in the same environment as the printer.
• To prevent damage to the toner cartridge, do not expose it to light for
more than a few minute.
Expected cartridge life
Reinsert the toner cartridge and close the front cover.
Plug in the power cord and turn the printer on.
The life of the toner cartridge depends on the amount of toner that print
jobs require. When printing text at ISO 19752 5% coverage, a new toner
cartridge lasts an average of either 8,000 or 4,000 pages. (The original
toner cartridge supplied with the printer lasts an average of 4,000
pages.) The actual number may also be different depending on the print
density of the pages you print on, and the number of pages may be
affected by operating environment, printing interval, media type, and
media size. If you print a lot of graphics, you may need to change the
cartridge more often.
Printing a cleaning sheet
Saving Toner
If you are experiencing blurred, faded, or smeared printouts, you can
clear the problem by printing a cleaning sheet, provided by your printer.
You can print:
To save toner, press Toner Save on the control panel. The button
backlight turns on.
Using this feature extends the life of the toner cartridge and reduce your
cost per page, but it also reduces print quality.

Clearing paper jams
Note
When removing paper that is jammed in the printer, if possible
always pull the paper in the direction that it normally moves so
as not to damage internal components. Always pull firmly and
evenly; do not jerk the paper. If the paper tears, ensure that all
fragments of paper are removed; otherwise a jam will occur
again.
This chapter provides helpful information for what to do if you encounter
an error while using your printer.
