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 or network card 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.
(6) Take care not to drop any small parts into the machine.
(7) Handling of the OPC Drum
- The OPC Drum can be irreparably damaged if it exposed to light.
Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandescent
room lighting. Exposure for as little as 5 mins can damage the surface? photoconductive properties
and will result in print quality degradation. Take extra care when servicing the printer. Remove the
OPC Drum and store it in a black bag or other lightproof container. Take care when working with the
covers(especially the top cover) open as light is admitted to the OPC area and can damage the OPC
Drum.

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.

ΘLSU(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.
Error
Phenomenon
Polygon Motor Error

Ι2nd Transfer Ass’y
• The life span: Print over 100,000 sheets (in 15~30 )
• Specification: Similar to CLP-300 Series
ΚFuser 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.

ΡFax
Implemented by based on the SiLab DAA (Data Access Arrangement) Solution, and is roughly composed
of two Chip Solution
• Si2435 (Modem) A Modem Chip which embeds SSD (System Side Device) for interfacing between LSD
and DIB of Si2435 Core
• Si3018 (DAA) A LIU (Line Interface Unit) Chip which is controlled by SSD and satisfies each PSTN
Requirements by modulating internal Configuration with connecting Tel Line.
Block Diagram
(SiliconDAA)
(Modem)
Signal Transition of DAA Solution
Line Interface Signal of Tel Line and LSD is Analog Signal. There are a A/D and a D/A Converter in the LSD,
so Analog Signal from Tel Line is converted in Digital through a A/D Converter in the DAA and transferred to
the SSD by the DIB Transformer. Digital Signal from the SSD is converted to Analog by a D/A Converter in
the DAA and transferred to Tel Line.

Scan Part
1) Pictorial 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) Pictorial 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.

2.2.3 CRUM
The CLX-317x 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, and electronics logo.
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)
-> Let cartridge refiller initialize manufacture information and life span information.

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 Help to the user although the error has occurred while printing.

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, re
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 re 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 rfe. 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 rst, 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 tted such as sensors,
motors or lamps as they may get hot.
3. Take care when tting, 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 retted 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.
