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.

2.2 System Overview
This chapter describes the functions and operating principles of the main components.
2.2.1 System Structure
The CLX-3185 series is roughly made up a Main Controller part (Main PBA), an Operation Panel part, a
Scanner part, a Fax part, and a Power part. Each part is separated modules which focus on common and
standard design of different kind products. The Main controller part is composed of one CPU and one Board
and works to control all the parts for printing, copying, scanning and faxing. The Operation Panel part is for
User’s interface. The Scanner part is composed of an ADF and a Platen and is connected with the Main
Controller by Harnesses. The Fax part and the ADF scanner part are not populated in the Model of CLX-3185
and CLX-3185N.

• No Manual Feeder
• Paper Detecting Sensor : Photo Sensor (Empty, Registration, Exit)
• Paper Size Sensor : None
② LSU(Laser Scan Unit)
The LSU unit is controlled by video controller. It scans the video data received from video controller with
laser beam by using the rotation principle of the polygon mirror to create the latent image on the OPC
drum. It is the core part of LBP.
The OPC drum rotates as the same speed as the paper feeding speed. It creates the /HSYNC signal and
sends it to the engine when the laser beam of the LSU reaches the end of the polygon mirror, and the
engine detects the /HSYNC signal to arrange the vertical line of the image on the paper. After detecting
the /HSYNC signal, the image data is sent to the LSU to arrange the its margin on the paper.
• Consisted of LD(Laser Diode) and Polygon Motor Control.

③ 2nd Transfer Ass’y
• The life span: Print over 100,000 sheets (in 15~30 )
④ Fuser Ass’y
This unit consists of Heat Roller, a Thermostat and a Thermistor. It melts and fuses the toner, transferred
by the transfer roller onto the paper, by applying pressure and high temperature to complete printing job.
* Heat Lamp : Kunckle Type
* Fusing system : 3-Roll Fusing type
- Heat roller : Pipe type (Lamp inside)
- Pressure roller
- Pressure roller Shaft
* Thermistor - Temperature-Measuring Device
* Thermostat - Critical Temperature-Detecting Device
* The life span – 100k(black)/color(25k)
Thermostat
When a heat lamp is overheated, a Thermostat cuts off the main power to prevent over-heating.
- Non-Cotact type Thermostat
Heat roller
The heat roller transfers the heat from the lamp to apply a heat on the paper. The surface of a heat
roller is coated with Teflon, so toner does not stick to the surface.
Pressure roller
A pressure roller mounted under a heat roller is made of a silicon resin, and the surface also is coated
with Teflon. When a paper passes between a heat roller and a pressure roller, toner adheres to the surface
of a paper permanently.

- Signal Transition of DAA Solution
1) Line Interface Signal of Tel Line and LSD is Analog Signal.
2) there is A/D, D/A Converter in LSD, so Analog Signal from Tel Line is converted in Digital through A/D
Converter in DAA and transfer to SSD by DIB Capacitor
Digital Signal from SSD is converted to Analog by D/A Converter in DAA and transfer to Tel Line
3) Transformer transfer Clock from SSD to LSD and Clock Frequency is 4.032MHz.
LSD full wave rectifies Clock to use as inner Power supply and also use as Main Clock for DIB Protocol
Sync between LSD and SSD. Transformer transfer Clock by separating Primary and Secondary, and
amplifies Clock Level to LSD by Coil Turns Ratio 1:1.16.
⑫ Scan Part
1) P
ictorial signal input part: output signal of CIS passes through Bypass Cap change to ADC at IP Main
and defined signal between AFE and IP Main processes the Image signal. When AFE accept each
pixel, CDS (Correlated Double Sampling) technique which samples arm-level twice is used on each
pixel by using IP signal.
2) P
ictorial image processing part: read CIS Pixel data in terms of 1200dpi Line and process LAT
algorithm on text mode, Error Diffusion Algorithm on Mixed mode, and store Data at Scan Buffer on PC
Scan mode without algorithm.
On every mode Shading Correction and Gamma Correction are executed ahead then processing is
executed later.

The CLX-3185 series engine will be equipped with electronics that can read and write data into EEPROM
otherwise known as CRUMs that reside within 1) C, M, Y, K Toner cartridges.
The CRUM has a company ID.
The CRUMs contain fixed data such as the low warning point, specified life point and also store the current
life count (pages count, pixels count, images count) and % of usage (gas gauge)
data.
■ In the case of Refill Toner Install
1) Perception of Refill Cartridge (when power is on or the cover is closed)
End of Life / life span data initialization -> judge to be Refill Cartridge
End of Life / life exhausted (simple refill) -> stop printing caused by life exhaustion
2) Operating
It is impossible to control appropriate development parameters, for there’s no toner specification data.
It runs with the setting of default development parameter. (Image quality will be degraded, for the lack of
appropriate respond to the change of time and environment.)
■ Process after CRU life expiration
1) Record the information of End of Life.
2) Clear some information of Operation Area.
-> Supplier/Model Name/MFC date/Serial Number (Manufacture Information)

Disassembly and Reassembly
3. 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.
3.1.2 Preautions when handling PBA
Static electricity can damage a PBA, always used approved anti-static precautions when handling or storing
a PBA.
>> Precautions when moving and storing PBA
1. Please keep PBA in a conductive case, anti-static bag, or wrapped in aluminum foil.
2. Do not store a PBA where it is exposed to direct sunlight.
>> Precautions when replacing PBA
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

3.2 Parts for Maintenance and Repair
3.2.1 Replacement interval for parts with a limited life
Some of the parts in this printer have a limited life, shorter than that of the whole machine. These parts must
be replaced periodically.
The table below shows the interval at which these parts should be replaced.
The table shows the life of each part, and is measured when using A4 paper. When servicing a machine
always check the status of these parts using the control panel and ensure that parts are replaced at the
appropriate times otherwise a general degradation in print quality will occur.

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
4) Disassembly of DEVE drive ass’y and
the main drive ass’y
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.
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.
2) Disassembly of the ITB unit
5) Disassembly of terminal parts
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.
Do not adjust the variable resistors on the PBA.
They have been already adjusted in the factory.
6) Disassembly of the fuser unit
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 cold 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.

- 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.

4.2.7 Common Linux Problems
I can't change settings in the

You need to have administrator privileges to be able
to change global settings.
I am using the KDE
desktop but the configuration tool
and LLPR won't start.
You may 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.
I get a "Some options

editing the printer
settings.
Some versions of the KDE or GNOME desktop
environments may require that you restart your
session for the changes to take effect.
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.
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.
The N-up setting
does not work correctly for some of my
documents.
I am using BSD lpr
(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.
