if swallowed you should contact a doctor.
1.2.2 Electric Shock and Fire Safety Precautions
Failure to follow the following instructions could cause electric shock or potentially cause a fire.
(1) Use only the correct voltage, failure to do so could damage the printer and potentially cause a fire or electric
shock.
(2) Use only the power cable supplied with the printer. Use of an incorrectly specified cable could cause the cable
to overheat and potentially cause a fire.
(3) Do not overload the power socket, this could lead to overheating of the cables inside the wall and could lead to
a fire.
(4) Do not allow water or other liquids to spill into the printer, this can cause electric shock. Do not allow paper
clips, pins or other foreign objects to fall into the printer these could cause a short circuit leading to an electric
shock or fire hazard..
(5) Never touch the plugs on either end of the power cable with wet hands, this can cause electric shock. When
servicing the printer remove the power plug from the wall socket.
(6) Use caution when inserting or removing the power connector. The power connector must be inserted completely otherwise a poor contact could cause overheating possibly leading to a fire. When removing the power
connector grip it firmly and pull.
(7) Take care of the power cable. Do not allow it to become twisted, bent sharply round corners or otherwise
damaged. Do not place objects on top of the power cable. If the power cable is damaged it could overheat and
cause a fire or exposed cables could cause an electric shock. Replace a damaged power cable immediately,
do not reuse or repair the damaged cable. Some chemicals can attack the coating on the power cable,
weakening the cover or exposing cables causing fire and shock risks.
(8) Ensure that the power sockets and plugs are not cracked or broken in any way. Any such defects should be
repaired immediately. Take care not to cut or damage the power cable or plugs when moving the machine.
(9) Use caution during thunder or lightening storms. Samsung recommend that this machine be disconnected from
the power source when such weather conditions are expected. Do not touch the machine or the power cord if it
is still connected to the wall socket in these weather conditions.
(10) Avoid damp or dusty areas, install the printer in a clean well ventilated location. Do not position the machine
near a humidifier. Damp and dust build up inside the machine can lead to overheating and cause a fire.
(11) Do not position the printer in direct sunlight. This will cause the temperature inside the printer to rise possibly
leading to the printer failing to work properly and in extreme conditions could lead to a fire.
(12) Do not insert any metal objects into the machine through the ventilator fan or other part of the casing, it could
make contact with a high voltage conductor inside the machine and cause an electric shock.

Precautions
1.2.3 Handling Precautions
The following instructions are for your own personal safety, to avoid injury and so as not to damage the printer
(1) Ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could cause
the printer to tip or fall.
(2) The printer contains many rollers, gears and fans. Take great care to ensure that you do not catch your fingers,
hair or clothing in any of these rotating devices.
(3) Do not place any small metal objects, containers of water, chemicals or other liquids close to the printer which if
spilled could get into the machine and cause damage or a shock or fire hazard.
(4) Do not install the machine in areas with high dust or moisture levels, beside on open window or close to a
humidifier or heater. Damage could be caused to the printer in such areas.
(5) Do not place candles, burning cigarettes, etc. on the printer, these could cause a fire.
1.2.4 Assembly / Disassembly Precautions
Replace parts carefully, always use Samsung parts. Take care to note the exact location of parts and also
cable routing before dismantling any part of the machine. Ensure all parts and cables are replaced correctly.
Please carry out the following procedures before dismantling the printer or replacing any parts.
(1) Check the contents of the machine memory and make a note of any user settings. These will be erased if the
mainboard is replaced.
(2) Ensure that power is disconnected before servicing or replacing any electrical parts.
(3) Disconnect printer interface cables and power cables.
(4) Only use approved spare parts. Ensure that part number, product name, any voltage, current or temperature
rating are correct.
(5) When removing or re-fitting any parts do not use excessive force, especially when fitting screws into plastic.

Precautions
1.3 ESD Precautions
Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called
“Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits, some field
effect transistors, and semiconductor “chip” components.
The techniques outlined below should be followed to help reduce the incidence of component damage caused by
static electricity.
Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any
electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the
unit under test.
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as
aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static” can
generate electrical charges sufficient to damage ESDs.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage ESDs.
6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most
replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conductive material.
7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing
together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to
damage an ESD.

2.3.2 Language Monitor
Language Monitor is a part of the Printer Driver and the Windows Spool System. The main roll of the Language
Monitor is that sends a job start message to the Status Monitor. Therefore the Status Monitor
can start polling to get the printer status.
The second roll is that sends the job information such as User ID and Job ID to the Status Monitor and the Printer
F/W. Hence the Status Monitor can stop polling because the Printer F/W informs the Status Monitor that printing
job is complete.
2.3.3 Status Monitor
Status Monitor has no user interface. It shows only HTML help when any error occurs during printing jobs.

Status Monitor Data Flow
After polling is started, Status Monitor has to know when it stops the polling. For this reason, the Network
Printer Server should inform of completing job when the printing job is finished.
When Status Monitor requests a job status, the Printer Server returns the job table that contains user id, job
id, and job status (printing or complete or canceled).
2.3.5 Printer Driver <-> Status Monitor
The Printer Driver and the Status Monitor can set/get some data to the system registry to share the Status Monitor
information such as the polling interval.
When the user wants to set the option of the Status Monitor manually, he or she can set it using the Printer Driver
User Interface. So, if the user set option that the Status Monitor is disabled, the Status Monitor can’s show HTML

Disassembly and Reassembly
3.1 Precautions when replacing parts
3.1.1 Precautions when assembling and disassembling
* Use only approved Samsung spare parts. Ensure that part number, product name, any voltage, current or
temperature rating are correct. Failure to do so could result in damage to the machine, circuit overload,
fire or electric shock.
* Do not make any unauthorized changes or additions to the printer, these could cause the printer to malfunction and create electric shock or fire hazards.
* Take care when dismantling the unit to note where each screw goes. There are 19 different screws. Use of
the wrong screw could lead to system failure, short circuit or electric shock.
* Do not disassemble the LSU unit. Once it is disassembled dust is admitted to the mirror chamber and will
seriously degrade print quality. There are no serviceable parts inside.
* Regularly check the condition of the power cord, plug and socket. Bad contacts could lead to overheating
and firfe. Damaged cables could lead to electric shock or unit malfunction.

1. Disconnect power connectors first, before disconnecting other cables
2. Do not touch any soldered connections, connector terminals or other electronic parts when handling
insulated parts.
>> Precautions when checking PBA
1. Before touching a PBA, please touch other grounded areas of the chassis to discharge any static electrical charge on the body.
2. Take care not to touch the PBA with your bare hands or metal objects as you could create a short circuit or get an electric shock. Take extra care when handling PBAs with moving parts fitted such as sensors, motors or lamps as they may get hot.
3. Take care when fitting, or removing, screws. Look out for hidden screws. Always ensure that the correct
screw is used and always ensure that when toothed washers are removed they are refitted in their original positions.
3.1.3 Releasing Plastic Latches
Many of the parts are held in place with plastic latches. The latches break easily; release them carefully.
To remove such parts, press the hook end of the latch away from the part to
which it is latched.

3.2.2 Printer Cleaning
A printer should be regularly cleaned, especially if it is used in a dusty environment. This will ensure that
print quality remains high and failure due to contamination of printing services is less likely to occur.
* Clean the printer with a soft, lint free, cloth dipped in a "Recommended cleaner"
"Recommended cleaner" can be purchased from our service center. (where available)
* Do not touch the transfer roller when cleaning the inside of the printer. Grease and oils from the
skin will contaminate the surface and reduce print quality.
* Do not touch transfer roller when cleaning inside of machine. If transfer roller gets dirty, printing
quality could be low.
* Please refer to the User Manual for cleaning instructions.

3.3 Information Related to Disassembly and Assembly.
3.3.1 Special service parts
Never disassemble or adjust the items mentioned, a stock of these items should be maintained.
1) Disassembly of the LSU unit
There are no serviceable parts inside the
LSU. Alignment of the mirrors is critical.
Opening the LSU will allow dust into the
laser and significantly reduce print quality.
It is very dangerous to operate or service
a machine with the LSU open or system
interlocks disabled. Exposure to laser
radiation can cause blindness.
2) Disassembly of the ITB unit
Do not disassemble the ITB. The alignment of the home sensor is critical and is
set up in the factory on a special jig.
Incorrect re-assembly will cause print
quality degradation.
3) Care of the Toner cartridge
Toner cartridges contain an extremely fine
powder. Please keep toner cartridges
away from children. The toner powder
contained in the toner cartridge may be
harmful and if swallowed you should contact a doctor. Take care not to spill toner spillages should be cleaned with a
vacume cleaner and washed in could
water (hot water sets the toner). Do not
touch the developer roller surface as contamination will reduce print quality. Take
care not to damage the roller's surface
when installing or removing a toner cartridge.
4) Disassembly of DEVE drive ass'y
and the main drive ass'y
The alignment of the drive mechanism is
critical and it has been set up in factory
using a jig and a driving gear. It is adjusted for the best gearing alignment. If the
motor is disassembled alignment would
not be maintained and this could cause
operational noise and image problems:
image alignment and toner distribution
may be affected.
5) Disassembly of terminal parts
Do not adjust the variable resistors on the
PBA. They have been already adjusted in
the factory.
6) Disassembly of the fuser unit
- The fuser melts toner onto the paper at
a high temperature: therefore, you need
to take special care not to get burned by
a hot fuser. When removing the fuser
from a set that has recently been operating you need to take extra care.
- Do not touch an AC line (Copper contact) on a main frame even after removing the fuser.

(Slackware, Debian, older
distributions) and some options chosen
in LLPR don't seem to
take effect.
I am trying to print a document in
Landscape mode, but it prints
rotated and cropped.
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. The
default queue in LPRng is defined as the first queue
in /etc./printcap, and therefore 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 an 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.
The N-up feature is achieved through postprocessing of the PostScript data that is 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 that rely on post-processing if the
document being printed isn't compliant.
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, you may have exceeded
the length of the options and some of your choices
won't be passed to the programs
responsible for implementing them. Try to select
fewer options that deviate from the defaults, to save
on memory usage.
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 set to its default
Portrait setting, to avoid unwanted rotations of the
page that would result in cropped output.

Some pages come
out all white (nothing is printed), and
I am using CUPS.
I can't print to an SMB (Windows) printer.
My application seems to
be frozen while LLPR is running.
How do I specify the IP
address of my SMB server?
Some documents come out
as white pages when printing.
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.
To be able to configure and use SMB-shared printers
(such as printers shared on a Windows printer), 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.
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.
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 you 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 versions of CUPS, especially those shipped
with Mandrake Linux before the 8.1 release, have
some known bugs when processing PostScript
output from some applications. Try upgrading to the
latest version of CUPS (at least 1.1.14). Some RPM
packages for the 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
choose them in LLPR.
I configured a printer to
print to a file, but I get "Permission
denied" errors.
There may be some local options defined in your ~/ .
lpoptions file, which are manipulated by the lpoptions
command. These options are always 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
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 GDI)
printer, I sometimes get error messages
printing instead of my
document.
Unfortunately, some Unix applications may generate
non-compliant 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.
Some color images come out all black.
This is a known bug in Ghostscript (until GNU
Ghostscript version 7.05) when the base color space
of the document is indexed color space and it is
converted through CIE color space. Because
Postscript uses CIE color space for Color Matching
System, you should upgrade Ghostscript on your
system to at least GNU Ghostscript version 7.06 or
later. You can find recent Ghostscript versions at
www.ghostscript.com.
