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 eld 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 classied as “anti-static”

can generate electrical charges sufcient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufcient 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 oor, can generate static electricity sufcient to damage an ESD.

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.

Error Phenomenon

Polygon Motor Error The Rotation of Polygon Motor can not reach stable

Hsync Error Though the rotation of Polygon Motor reach stable, the signal of Hsync is

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 Teon, 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 Teon. When a paper passes between a heat roller and a pressure roller, toner adheres to the surface

of a paper permanently.

Scan Part

1) Pictorial signal input part: output signal of CIS passes through Bypass Cap change to ADC at IP Main

and dened 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-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 xed data such as the low warning point, specied 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 Rell Toner Install

1) Perception of Rell Cartridge (when power is on or the cover is closed) End of Life / life span data initialization -> judge to be Rell Cartridge End of Life / life exhausted (simple rell) -> stop printing caused by life exhaustion

2) Operating It is impossible to control appropriate development parameters, for there’s no toner specication 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 reller initialize manufacture information and life span information.

2.3.1 Architecture

The belt CRUM interface board is a transmission belt CRUM interface board of the photoelectric Dry Color Laser Printer, mounted on the printer body, making it possible to physically combine the body and the belt CRUM board.

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.

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 nished. 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 retted 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 signicantly 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 ne

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.

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.
