Using Overlays
What is an Overlay?
Dear ABC
Regards
WORLD BEST
An overlay is text and/or images stored in the computer hard
disk drive (HDD) as a special file format that can be printed on
any document. Overlays are often used to take the place of
preprinted forms and letterhead paper. Rather than using
preprinted letterhead, you can create an overlay containing the
exact same information that is currently on your letterhead. To
print a letter with your company’s letterhead, you do not need
to load preprinted letterhead paper in the printer. You need only
tell the printer to print the letterhead overlay on your document.
Creating a New Page Overlay
To use a page overlay, you must create a new page overlay
containing your logo or image.
1 Create or open a document containing text or an image for
WORLD BEST
use in a new page overlay. Position the items exactly as you
wish them to appear when printed as an overlay. If needed,
save the file for later use.
2 To change the print settings from your software application,
access the printer properties. See page 4.2.
3 Click the Extras tab, and click Edit button in the Overlay
section.

MAINTAINING YOUR PRINTER
This chapter provides suggestions for high-quality and
economical printing and information for maintaining the
toner cartridge and the printer.
This chapter includes:
• Maintaining the Toner Cartridge
• Cleaning the Printer
• Printing Configuration Pages
• Consumables and Replacement Parts
Maintaining the Toner Cartridge
Toner cartridge storage
To get the maximum results 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 printer warranty does
not cover damage caused by using a refilled cartridge.
• Store toner cartridges 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 minutes.
Toner cartridge life expectancy
The life of the toner cartridge depends on the amount of toner
that print jobs require. When printing text at 5% coverage, a
new toner cartridge lasts an average of 5,000 pages. (The
original toner cartridge supplied with the printer lasts an
average of 3,000 pages.)
Saving toner
To save toner, press the Cancel button on the printer control
panel. The button will be lit. You can also enable the Toner Save
in the printer properties. Refer to “Using the Toner Save Mode”
on page 4.9. Selecting this option will extend the life of the toner
cartridge and reduce your cost per page, but will reduce the
print quality.
5.2
MAINTAINING YOUR PRINTER
Redistributing Toner
When toner is low, faded or light areas may appear on a printed
page. You may be able to temporarily improve the print quality
by redistributing the toner. The following procedures may allow
you to finish the current print job before replacing the toner
cartridge.
1 Grasp the front cover and pull it toward you to open.
2 Pull the toner cartridge and remove it from the printer.
CAUTIONS:
• Avoid reaching too far into the printer. The fusing area may be
hot.
• To prevent damage to the toner cartridge, do not expose it to
light for more than a few minutes. Cover it with a piece of paper,
if left exposed for more than a few minutes and keep it in a flat
and clean place.
MAINTAINING YOUR PRINTER
5.3
3 Gently shake the toner cartridge from side to side five or six
times to redistribute the toner.
NOTE: If toner gets on your clothing, wipe it off with a dry cloth
and wash clothing in cold water. Hot water sets toner into fabric.
4 Reinsert the toner cartridge into the printer. Ensure that the
toner cartridge snaps into place.
5 Close the front cover. Make sure that the cover is securely
closed. If it is not firmly closed, printing errors may occur
when you print.
5.4
MAINTAINING YOUR PRINTER
Replacing the Toner Cartridge
If the print remains light after redistributing the toner (see
page 5.3), replace the toner cartridge.
Remove the old cartridge and install a new toner cartridge. See
“Installing the Toner Cartridge” on page 2.4.
Cleaning the Printer
To maintain print quality, follow the cleaning procedures below
each time the toner cartridge is replaced or if print quality
problems occur.
NOTE: 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 quality problems.
CAUTION: Cleaning the cabinet of the printer with surfactants
containing large amounts of alcohol, solvent, or other strong
substances can discolor or crack the cabinet.
Cleaning the Outside
Clean the cabinet of the printer with a soft, lint-free cloth. You
can dampen the cloth slightly with water, but be careful not to
let any water drip onto the printer or inside of it.
Cleaning the Inside
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. Cleaning
the inside of the printer will eliminate or reduce these problems.
Cleaning inside the printer
1 Turn the printer off and unplug the power cord, then wait
for the printer to cool.

2 Open the front cover. Pull the toner cartridge and remove it
from the printer.
3 With a dry, lint-free cloth, wipe away any dust and spilled
toner from the toner cartridge area and the toner cartridge
cavity.
NOTE: To prevent damage to the toner cartridge, do not expose it
to light for more than a few minutes. Cover it with a piece of paper,
if necessary and keep it in a flat and clean place. Also, do not touch
the black transfer roller inside the printer.

MAINTAINING YOUR PRINTER
4 Reinsert the toner cartridge and close the cover. Make sure
that the cover is securely closed. If it is not firmly closed,
printing errors may occur when you print.
5 Plug in the power cord, and turn the printer on.
Printing a cleaning sheet
If you are experiencing blurred, faded, or smeared printouts,
printing a cleaning sheet will clean the drum inside the toner
cartridge. This process will produce a page with toner debris,
which should be discarded.
1 Ensure that the printer is turned on and in the Ready mode
with paper loaded in the tray.
2 Press and hold down the Cancel button on the control
panel for about 10 seconds.
MAINTAINING YOUR PRINTER
5.7
3 Your printer automatically picks up a sheet of paper from
the tray and prints out a cleaning sheet with dust or toner
particles on it.
NOTE: The cartridge cleaning process takes some time. To stop
the process, turn the power off.
Printing Configuration Pages
From the printer’s control panel, you can print a Configuration
page. Use the configuration page to view current printer
settings, to help troubleshoot printer problems, or to verify
installation of optional accessories, such as memory, optional
tray, and printer languages.
If your printer has a network card, the network configuration sheet
prints out with a printer configuration sheet.
To print configuration pages:
1 Ensure that the printer is turned on and in the Ready mode
with paper loaded in the tray.
2 Press and hold down the Cancel button on the control
panel for about 6 seconds.

Tips for Avoiding Paper Jams
By selecting the correct paper types, most paper jams can be
avoided. If a paper jam occurs, follow the steps outlined in
“Clearing Paper Jams” on page 6.7.
• Follow the procedures in “Loading Paper” on page 2.7. Ensure
that the adjustable guides are positioned correctly.
• Do not overload the paper tray. Ensure that the paper is below
the paper limit mark on the inside wall of the tray.
• Do not remove the paper from the tray while printing.
• Flex, fan, and straighten the paper before loading.
• Do not use creased, damp, or highly curled paper.
• Do not mix paper types in the tray.
• Use only recommended print materials. See “Paper
Specifications” on page E.3.
• Ensure that the recommended print side is facing down when
loading paper in the tray and facing up in the Multi-Purpose
Tray.
6.14 SOLVING PROBLEMS
Solving Print Quality Problems
If the inside of the printer is dirty, or paper is improperly loaded,
print quality maybe reduced. See the table below to
troubleshoot the problem.
Problem
Solution
Light or faded
print
If a vertical white streak or faded area appears on the page:
• The toner supply is low. You may be able to temporarily
extend the toner cartridge life. See “Redistributing Toner” on
page 5.3. If this does not improve the print quality, install a
new toner cartridge.
• The paper may not meet paper specifications (for example,
the paper is too moist or too rough). See “Paper
Specifications” on page E.3.
• If the entire page is light, the print resolution setting is too
light or Toner Save Mode is on. Adjust the print resolution
and Toner Save Mode in the printer properties. See
page 4.22 and page 4.9 respectively.
• A combination of faded or smeared defects may indicate that
the toner cartridge needs cleaning. See “Cleaning the Inside”
on page 5.5.
• The surface of the LSU may be dirty. Clean the LSU. See
“Cleaning the Inside” on page 5.5.

job.
• The moisture content of the paper is uneven or the paper has
moist spots on its surface. Try a different brand of paper. See
“Paper Specifications” on page E.3.
• The paper lot is bad. The manufacturing processes can cause
some areas to reject toner. Try a different kind or brand of
paper.
• The toner cartridge may be defective. See “Vertical repetitive
defects” on the next page.

If the amount of background shading becomes unacceptable,
the procedures below may fix the problem.
• Change to a lighter weight pages. See “Paper Specifications”
on page E.3.
• Check the printer’s environment; very dry (low humidity) or
high humidity (higher than 80% RH) conditions can increase
the amount of background shading.
• Remove the old toner cartridge and install a new one. See
“Installing the Toner Cartridge” on page 2.4.
Toner smear
• Clean the inside of the printer. See “Cleaning the Inside” on
page 5.5.
• Check the paper type and quality. See “Paper Specifications”
on page E.3.
• Remove the toner cartridge and install a new one. See
“Installing the Toner Cartridge” on page 2.4.
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the page at
even intervals:
• The toner cartridge may be damaged. If a repetitive mark
occurs on the page, print a cleaning sheet several times to
clean the cartridge; see page 5.7. After the printout, if you
still have the same problems, install a new toner cartridge.
See “Installing the Toner Cartridge” on page 2.4.
• Parts of the printer may have toner on them. If the defects
occur on the back of the page, the problem will likely correct
itself after a few more pages.

Background
scatter
Background scatter results from bits of toner 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 the printer properties.
Misformed
characters
• If characters are improperly formed and producing hollow
images, the paper stock may be too slick. Try a different
paper. See “Paper Specifications” on page E.3.
• If characters are improperly formed and producing a wavy
effect, the scanner unit may need service. Verify that it also
occurs on a demo page (see page 2.16). For service, contact
a service representative.

with your PC for further information on Windows error messages.
SOLVING PROBLEMS 6.21
Common Linux Problems
Problem
Possible Cause and Solution
I can’t change settings in
the configuration tool.
You need to have administrator privileges to be able to affect
global settings.
I am using the KDE
desktop but the
configuration tool and LLPR
won’t start.
Maybe you do not have the GTK libraries installed. These
usually come with most Linux distributions, but you may have
to install them manually. Refer to your distribution’s
installation manual for more details about installing additional
packages.
I just installed this
package but can’t find
entries in the KDE/Gnome
menus.
Some versions of the KDE or GNOME desktop environments
may require that you restart your session for the changes to
take effect.
I get a “Some options are
not selected” error
message while editing the
printer settings.
Some printers have conflicting settings, meaning that some
settings for two options can’t be selected at the same time.
When you change a setting and the Printer Package detects
such a conflict, the conflicting option is changed to a “No
Choice” value, and you have to choose an option that does
not conflict before being able to submit the changes.
I can’t make a printer the
system default.
In some conditions, it may not be possible to change the
default queue. This happens with some variants of LPRng,
especially on recent RedHat systems that use the “printconf”
database of queues.
When using printconf, the /etc/printcap file is automatically
refreshed from the database of printers managed by the
system (usually through the “printtool” command), and the
queues in /etc/printcap.local are appended to the resulting
file. Since the default queue in LPRng is defined as the first
queue in /etc/printcap, it is not possible for the Linux Printer
Package to change the default when some queues have
otherwise been defined using printtool.
LPD systems identify the default queue as the one named “lp”.
Thus, if there is already a queue by this name, and if it
doesn’t have any alias, you won’t be able to change the
default. To work around this, you can either delete the queue
or rename it by manually editing the /etc/printcap file.
The N-up setting does not
work correctly for some of
my documents.
6.22 SOLVING PROBLEMS
The N-up feature is achieved through post-processing of the
PostScript data that is being sent to the printing system.
However, such post-processing can only be adequately
achieved if the PostScript data conforms to the Adobe
Document Structuting Conventions. Problems may arise when
using N-up and other features relying on post-processing if
the document being printed isn’t compliant.
Problem
Possible Cause and Solution
I am using BSD lpr
(Slackware, Debian, older
distributions) and some
options chosen in LLPR
don’t seem to take effect.
Legacy BSD lpr systems have a hard limitation on the length
of the option string that can be passed to the printing system.
As such, if you selected a number of different options, the
limitation length of the options may be exceeded and some of
your choices won’t be passed to the programmes responsible
for implementing them. Try to select less options that deviate
from the defaults, to save on memory usage.
I am trying to print a
document in Landscape
mode, but it prints rotated
and cropped.
Most Unix applications that offer a Landscape orientation
option in their printing options will generate correct PostScript
code that should be printed as is. In that case, you need to
make sure that you leave the LLPR option to its default
Portrait setting, to avoid unwanted rotations of the page that
would result in a cropped output.
Some pages come out all
white (nothing is printed),
and I am using CUPS.
If the data being sent is in Encapsulated PostScript (EPS)
format, some earlier versions of CUPS (1.1.10 and before)
have a bug preventing them from being processed correctly.
When going through LLPR to print, the Printer Package will
work around this issue by converting the data to regular
PostScript. However, if your application bypasses LLPR and
feeds EPS data to CUPS, the document may not print
correctly.
I can’t print to a SMB
(Windows) printer.
To be able to configure and use SMB-shared printers (such as
printers shared on a Windows machine), you need to have a
correct installation of the SAMBA package that enables that
feature. The “smbclient” command should be available and
usable on your system.
My application seems to be
frozen while LLPR is
running.
Most Unix applications will expect a command like the regular
“lpr” command to be non-interactive and thus return
immediately. Since LLPR is waiting for user input before
passing the job on to the print spooler, very often the
application will wait for the process to return, and thus will
appear to be frozen (its windows won’t refresh). This is
normal and the application should resume functioning
correctly after the user exits LLPR.
How do I specify the IP
address of my SMB server?
It can be specified in the “Add Printer” dialogue of the
configuration tool, if you don’t use the CUPS printing system.
Unfortunately, CUPS currently doesn’t allow one to specify the
IP address of SMB printers, so you will have to be able to
browse the resource with Samba in order to be able to print.
Some documents come out
as white pages when
printing.
Some versions of CUPS, especially those shipped with
Mandrake Linux before the 8.1 release, have some known
bugs when processing the PostScript output from some
applications. Try upgrading to the latest version of CUPS (at
least 1.1.14). Some RPM packages for most popular
distributions are provided as a convenience with this Linux
Printing Package.
SOLVING PROBLEMS 6.23
Problem
Possible Cause and Solution
I have CUPS and some
options (such as N-up)
seem to be always enabled
even though I don’t pick
them in LLPR.
There may be some local options defined in your ~/.lpoptions
file, which is manipulated by the lpoptions command. These
options will always be used if not overridden by LLPR settings.
To get rid of all options for a printer, run the following
command, replacing “printer” with the name of the queue:
lpoptions -x printer
I configured a printer to
print to a file, but I get
“Permission denied” errors.
Most printing systems will not run as the super-user but as a
special user (usually “lp”). Therefore, make sure that the file
you have chosen to print to is accessible to the user owning
the spooler daemon.
On my SPL (or PCL)
printer, I sometimes get
error messages printing
instead of my document.
Unfortunately, some Unix applications may generate noncompliant PostScript output that may not be supported by
Ghostscript, or even the printer itself in PostScript mode. You
can try to capture the output to a file and view the results
with Ghostscript (gv or ghostview will allow you to do so
interactively) and see if you get error messages. However,
since the application is probably at fault, contact your
software vendor to inform them of the issue.

About the Remote Control Panel
DOS users have access to many printer features through specific
DOS printer drivers; however, many software manufactures do
not develop printer drivers for their software programmes. Your
printer provides the software control panel for improved printer
control when DOS printer drivers are not available or when
certain print settings are not available through DOS software
programmes.
NOTE: The printer’s Remote Control Panel is not a printer driver.
It should be used to set print settings that are not available
through DOS software programmes. Printer drivers are supplied by
the manufacturers of your DOS software programmes. If your DOS
software Programme does not include a printer driver for your
printer, contact the manufacturer of the software or use one of the
alternate printer drivers.
Installing the Remote Control Panel
1 Insert the supplied CD-ROM into your CD-ROM drive.
The CD-ROM should automatically run and an maintenance
window appears.
If the maintenance window does not appear, click Start and

You can configure various printer features.
• Emulation selects the emulation for printing a document.
The factory default is Auto.
• Power Save determines the length of time the printer waits
after a job is printed before it goes to a reduced power state.
If the printer is used frequently, select OFF which keeps the
printer ready to print with the minimum warm-up time. This
uses more power to keep the printer warm and ready to print.
• Auto Continue determines what action the printer should
take if the Multi-Purpose Tray is empty when a manual feed

pick up the paper from the tray 1 after fifteen seconds.
Otherwise, the printer will wait for you to load paper in the
Multi-Purpose Tray.
• Jam Recovery determines what action the printer should
take when a paper jam occurs. If it is unchecked, the printer
does not reprint a page that has jammed. If it is checked, the
printer keeps the image in memory for a printed page until
the printer signals that the page has successfully printed. The
printer reprints all jammed pages.
• Toner save determines the toner quantity the printer should
use when printing. If it is checked, the printer conserves
toner when printing. The default value is unchecked, which
provides 100% usage.
C.6 PRINTING FROM DOS APPLICATIONS
Job Tab
You can set options for improving the quality of your print job.
• Toner Density determines the toner density of the page.

Paper Specifications
Overview
Your printer accepts a variety of print materials, such as cutsheet paper (including up to 100% recycled fiber content
paper), envelopes, labels, transparencies, and custom-size
paper. Properties, such as weight, composition, grain, and
moisture content, are important factors affecting the printer’s
performance and the output quality. Paper that does not meet
the guidelines outlined in this User’s Guide can cause the
following problems:
• Poor print quality
• Increased paper jams
• Premature wear on the printer.
NOTES:
• Some paper may meet all of the guidelines in this guide 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 paper, ensure that the
paper meets the requirements specified in this User’s Guide.
CAUTION: Using paper that does not meet these specifications
may cause problems, requiring repairs. These repairs are not
covered by the Samsung warranty or service agreements.

Guidelines for Using Paper
For the best result, use conventional 75 g/m2 (20 lb) paper.
Ensure that the paper is of good quality, and free of cuts, nicks,
tears, spots, loose particles, dust, wrinkles, voids, and curled or
bent edges.
If you are unsure of what type of paper you are loading, such as
bond or recycled paper, check the label on the package.
The following problems may cause print quality deviations,
jamming, or even damage to the printer.

NOTES:
• Do not use letterhead paper printed with low-temperature inks,
such as those used in some types of thermography.
• Do not use raised or embossed letterhead.
• The printer uses heat and pressure to fuse toner to the paper.
Insure that any coloured paper or preprinted forms use inks that
are compatible with this fusing temperature (200 °C or 392 °F
for 0.1 second).

Printer and Paper Storage Environment
Paper storage environment conditions directly affect the feed
operation.
Ideally, the printer and paper storage environment should be at
or near room temperature, and not too dry or humid. Remember
that paper is hygroscopic; it absorbs and loses moisture rapidly.
Heat works with humidity to damage paper. Heat causes the
moisture in paper to evaporate, while cold causes it to condense
on the sheets. Heating systems and air conditioners remove
most of the humidity from a room. As paper is opened and used,
it loses moisture, causing streaks and smudging. Humid
weather or water coolers can cause the humidity to increase in
a room. As paper is opened and used it absorbs any excess
moisture, causing light print and dropouts. Also, as paper loses
and gains moisture it can become distorted. This can cause
paper jams.
Care should be taken not to purchase more paper than can be
used in a short time (about 3 months). Paper stored for long
periods may experience heat and moisture extremes, which can
cause damage. Planning is important to prevent damage to
large supplies of paper.
Unopened paper in sealed reams can remain stable for several
months before use. Opened packages of paper have more
potential for environment damage, especially if they are not
wrapped with a moisture-proof barrier.
The paper storage environment should be properly maintained
to ensure optimum printer performance. The optimum condition
is 20° to 24°C (68° to 75°F), with a relative humidity of 45% to
55%. The following guidelines should be considered when
evaluating the paper’s storage environment:
• Paper should be stored at or near room temperature.
• The air should not be too dry or too humid.
• The best way to store an opened ream of paper is to rewrap it
tightly in its moisture-proof wrapping. If the printer
environment is subject to extremes, unwrap only the amount
of paper to be used during the day’s operation to prevent
unwanted moisture changes.
SPECIFICATIONS
E.7
Envelopes
Envelope construction is critical. Envelope fold lines can vary
considerably, not only between manufacturers, but also within a
box from the same manufacturer. Successful printing on
envelopes depends upon the quality of the envelopes. When
selecting envelopes, consider the following components:
• 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 in.) 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.
• Size: You should only use envelopes within the following size
ranges.
Minimum
Multi-Purpose
Tray
76 X 127 mm
(3 X 5 in.)
Maximum
216 X 356 mm
(8.5 X 14 in.)
NOTES:
• Use only the Multi-Purpose Tray to print envelopes.
• You may experience some paper jams when using any media
with a length less than 127 mm (5.0 in.). This may be caused by
paper that has been affected by environmental conditions. For
optimum performance, make sure you are storing and handling
the paper correctly. Please refer to “Printer and Paper Storage
Environment” on page E.7.
E.8
SPECIFICATIONS
Envelopes with Double Side Seams
Double side-seam construction has vertical seams at both ends
of the envelope rather than diagonal seams. This style may be
more likely to wrinkle. Be sure the seam extends all the way to
the corner of the envelope as illustrated below.
Correct
Incorrect
Envelopes with Adhesive Strips or Flaps
Envelopes with a peel-off adhesive strip or with more than one
flap that folds over to seal must use adhesives compatible with
the heat and pressure in the printer. The extra flaps and strips
might cause wrinkling, creasing, or even jams and may even
damage the fuser.
Envelope Margins
The following gives typical address margins for a commercial
#10 or DL envelope.
Type of Address
Minimum
Maximum
Return address
15 mm (0.6 in.)
51 mm (2 in.)
Delivery address
51 mm (2 in.)
89 mm (3.5 in.)
NOTES:
• For best print quality, position margins no closer than 15 mm
(0.6 in.) from the edges of the envelope.
• Avoid printing over the area where the envelope’s seams meet.
Envelope Storage
Proper storage of envelopes helps contribute to print quality.
Envelopes should be stored flat. If air is trapped in an envelope,
creating an air bubble, then the envelope may wrinkle during
printing. See “Printing on Envelopes” on page 3.14.
SPECIFICATIONS
E.9
Labels
CAUTIONS:
• To avoid damaging the printer, use only labels recommended for
laser printers.
• To prevent serious jams, always use the Multi-Purpose Tray to
print labels and always use the rear output tray.
• Never print on the same sheet of labels more than once and
never print on a partial sheet of labels.
When selecting labels, consider the quality of each component:
• 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 with spaces
between the labels, causing serious jams.
• Curl: Prior to printing, labels must lie flat with no more than
13 mm (.5 in.) of curl in any direction.
• Condition: Do not use labels with wrinkles, bubbles, or other
indications of separation.
See “Printing on Labels” on page 3.17.
Transparencies
Transparencies used in the printer must be able to withstand
200 °C (392 °F), the printer’s fusing temperature.
CAUTION: To avoid damaging the printer, use only transparencies
recommended for use in laser printers.
See “Printing on Transparencies” on page 3.19.
