Printing 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
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.

Maintaining Your Printer
This chapter provides suggestions for maintaining the toner
cartridge and the printer.
This chapter includes:
• Maintaining the Toner Cartridge
• Cleaning the Printer
• 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 minute.
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 3,000 pages. (The
original toner cartridge supplied with the printer lasts an
average of 1,000 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 4.8. 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 Remove the toner cartridge from the printer.
Caution:
• 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.
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 the 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.
Replacing the Toner Cartridge
If the print remains light after redistributing 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.
5.4 MAINTAINING YOUR PRINTER
Cleaning the Printer
To maintain the print quality, follow the cleaning procedures
below each time the toner cartridge is replaced or if print quality
problems occur.
Notes:
• Do not use ammonia-based cleaners or volatile solvents, such as
thinner, on or around the printer. These can damage the printer.
• 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.
Cleaning the Outside
Wipe the outside surface of the printer with a soft, clean, lintfree cloth. You can dampen the cloth slightly with water, but be
careful not to be 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 specs 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 and remove the toner cartridge.
MAINTAINING YOUR PRINTER
5.5
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 minute. Cover it with a piece of paper,
if necessary. Also, do not touch the black transfer roller inside the
printer.
4 Reinsert the toner cartridge and close the cover.
5 Plug in the power cord, and turn the printer on.
5.6 MAINTAINING YOUR PRINTER
Printing a cleaning sheet
If you are experiencing blurred, faded or smeared printouts.
Printing a cleaning sheet cleans 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.
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
printing, turn the power off.
MAINTAINING YOUR PRINTER
5.7
Consumables and Replacement
Parts
From time to time, you will need to replace the roller and fuser
unit to maintain top performance and avoid print quality
problems and paper feed problems resulting from worn parts.
The following items should be replaced after you have printed a
specified number of pages. See the table below.
Items
Yield (Average)
Paper Feeding Roller
60,000
Transfer Roller
60,000
Pick-up roller
60,000
Fuser Unit

6.6 SOLVING PROBLEMS
Clearing Paper Jams
Occasionally, paper can be jammed during a print job. Some of
causes include:
• The tray is loaded improperly or overfilled.
• The tray has been pulled out during a print job.
• The front cover has been opened during a print job.
• Paper that does not meet paper specifications has been used.
See “Paper Specifications” on page 7.30.
• Paper that is outside of the supported size range has been
used. See “Paper Specifications” on page 7.30.
If a paper jam occurs, the On Line/Error LED on the control
panel lights red. Find and remove the jammed paper. If it is
invisible, look inside the printer.
In the Paper Exit Area
Note: Paper jams in this area may result in loose toner on the
page. If you get any toner on your clothes, wash them in cold
water as hot water will set the toner into the fabric.
1 If the paper jams as it exits to the output tray and a long
portion of the paper is visible, pull the paper straight out.
When you pull the jammed paper, if there is resistance and
the paper does not move immediately, stop pulling.

SOLVING PROBLEMS 6.11
Solving Print Quality Problems
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 7.30.
• 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 4.16 and 4.8 respectively.
• A combination of faded or smeared defects may indicate
that the toner cartridge needs cleaning. See “Cleaning the
Inside” on page 5.5.
Toner specs
• The paper may not meet specifications (for example, the
paper is too moist or too rough). See “Paper
Specifications” on page 7.30.
• The transfer roller may be dirty. See “Cleaning the Inside”
on page 5.5.
• The paper path may need cleaning. See “Cleaning the
Inside” on page 5.5.
Dropouts
If faded areas, generally rounded, occur randomly on the
page:
• A single sheet of paper may be defective. Try reprinting
the 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 7.30.
• 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 these steps do not correct the problems, contact a
service representative.
6.12 SOLVING PROBLEMS
Problem
Vertical lines
Solution
If black vertical streaks appear on the page:
• The drum inside the toner cartridge has probably been
scratched. Install a new toner cartridge.
Gray background
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 7.30.
• 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

on page 5.5.
• Check the paper type and quality. See “Paper
Specifications” on page 7.30.
• 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 5.5). After the printout, if
you still have the same problems, install a new toner
cartridge. See “Installing the Toner Cartridge” on
page 2.4.

occur on the back of the page, the problem will likely
correct itself after a few more pages.
• The fusing assembly may be damaged. Contact a service
representative.
SOLVING PROBLEMS 6.13
Problem
Solution
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 7.30.
• 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 by pressing the Cancel
button on the control panel when the printer is ready. For
service, contact a service representative.
Page skew
• Check the paper type and quality. See “Paper
Specifications” on page 7.30.
• 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
• Check the paper type and quality. Both high temperature
and humidity can cause paper curl. See “Paper
Specifications” on page 7.30.
• Turn over the stack of paper in the input tray. Also try
rotating the paper 180° in the input tray.
• Push the output lever and try printing to the face up
output slot.
6.14 SOLVING PROBLEMS

SOLVING PROBLEMS 6.15
Problem
Character Voids
Horizontal stripes
6.16 SOLVING PROBLEMS
Solution
Character voids are white areas within the parts of
characters that should be solid black:
• If you are using transparencies, try another type of
transparency. Because of the composition of the
transparency, some character voids are normal.
• You may be printing on the wrong surface on the paper.
Remove the paper and turn it around.
• The paper may not meet paper specifications. See “Paper
Specifications” on page 7.30.
If horizontally aligned black streaks or smears appear:
• The toner cartridge may be installed improperly. Remove
the cartridge and reinsert.
• The toner cartridge may be defective. Install a new toner
cartridge. See “Installing the Toner Cartridge” on
page 2.4.
• If the problem persists, the printer may require repair.
Contact a service representative.

SOLVING PROBLEMS 6.19
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,
therefore it is not possible for the Samsung 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, then 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.
6.20 SOLVING PROBLEMS
Problem
Possible Cause and Solution
The N-up setting does not
work correctly for some
of my documents.
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 Structing Conventions. Problems may
arise when using N-up and other features relying on postprocessing if the document being printed isn’t compliant.
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 length of the options may be
exceeded and some of your choices won’t be passed to the
programs 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.
SOLVING PROBLEMS 6.21
Problem
Possible Cause and Solution
How do I specify the IP
address of my SMB
server?
It can be specified in the “Add Printer” dialog of the
configuration tool, if you don’t use the CUPS printing
system. Unfortunately, CUPS currently doesn’t allow 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.
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 PCL (or SPL)
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 at probably fault, contact
your software vendor to inform them of the issue.
Common DOS problem
Problem
Possible Cause and Solution
When using the printer
in EPSON Dot Printer
Environment,
sometimes I can not get
the output I want.
Change the emulation to EPSON in the Config tab in the
Remote Control Panel. For detailed information about
selecting printer settings in the Remote Control Panel,
see page 7.22.

Printing from DOS Applications
While your printer is primarily a Windows printer, you can also
print from a DOS software program using the Remote Control
Panel utility provided in the supplied software CD-ROM.
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 programs. The
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
programs.
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 programs. Printer drivers are supplied by the
manufacturers of your DOS software programs. If your DOS
software program does not include a printer driver for your printer,
contact the manufacturer of the software program or use one of
the alternate printer drivers.
Installing the Remote Control Panel
The Remote Control Panel utility is provided on the printer
software CD-ROM.
1 Place the CD-ROM in the CD-ROM drive. Installation will
start automatically.
If the CD-ROM drive does not automatically run:

Selecting Print Settings
You can use this Remote Control Panel to select print settings
that may not be available on some DOS programs. Typically,
duplicate print settings that are selected from a DOS software
program override the ones that are selected in the Remote
Control Panel.
Starting Remote Control Panel
1 From the Start menu, select Programs.
2 Select Samsung ML-1750 Series, and then Remote
Control Panel.
3 The Remote Control Panel window allows you to access all
the information you need when using your printer. If
necessary, click other tabs on the top of the window to
access other features.
4 When you finish changing the settings, click Send until the
Print window is displayed.
7.22 APPENDIX
The Remote Control Panel allows you to access the following
features:
PRINTING
In this tab, you can configure general settings for printing.
• Paper Size sets the paper size.
• Orientation determines how the output is printed on the
page.
• Paper Tray sets the default paper source.
• Auto CR sets how the printer performs a carriage return.
• Copies sets the number of copies printed for each page.
• Quality specifies the print quality.
• Margins sets the top and left margin of the print material.
APPENDIX 7.23
CONFIG
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 when a manual feed print job is sent to the printer. If it
is checked, the printer will pick up the paper from the tray
after fifteen seconds. Otherwise, the printer will wait for you
to load paper in the manual feeder.
• 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 check, 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.
• Economode 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.
• Altitude: helps the printer optimize its output for a low
pressure area, such as a high mountain area.
7.24 APPENDIX
• Dark Text: allows all text in your document to be printed
darker than a normal document.
JOB
You can set options for improving the quality of your print job.
• Toner Density determines the toner density of page. The
default value is Medium.
• Paper Type provides the printer with information about the
type of paper to be used for a print job. For the best result,
set this to the paper type you loaded in the tray of the printer.
When using the plain paper, set this to Plain paper.
• Image Quality improves the print quality of your text and
image and make the characters and images appear smoother.
It is preset to None at the factory.
• Time out determins the amount of time (in seconds) the
printer will wait before printing the last pag of a print job that
does not end with a command to print the page or a formfeed
character. You can set from 0 to 300 seconds.
APPENDIX 7.25
TEST
This tab allows you to print a resident page to test your printer’s
performance.
• Self Test prints a configuration sheet. A list of the user
default settings and the amout of printer memory available
prints.
• Demo Page prints a demonstration page. It shows the
printer features and specifications.
7.26 APPENDIX
PCL
In this tab, you can configure various settings for PCL emulation.
• Typeface allows you to select the desired typeface. This
setting is ignored when the software application specifies a
font.
• Symbol Set determines the symbol set. A symbol set is a set
of alphabetic and numeric characters, punctuation, and special
symbols used when printing with a selected font.
• Pitch sets the font pitch (only if you have selected a scalable
monospaced font). Pitch refers to the number of fixed-space
characters in a horizontal inch of type.
• Point Size sets the font point size (only if you have selected
a scalable typographic font). Point size refers to the height of
the characters in the font. One point equals approximately
1/72 of an inch. You can select point sizes from 4.0 to 999.75
in increments of 0.25 points.
• Lines Per Page sets the number of lines that print on each
page. The setting can range from 5 to 128 lines per 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, insure 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.

APPENDIX 7.33
Printer and Paper Storage Environment
Paper storage environmental 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 required 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.
