wise damaged. Do not place objects on top of the power cable. If the power cable is damaged it could

overheat and cause a ire 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 ire 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 humidiier. Damp and dust build up inside the machine can lead to overheating and

cause a ire.

(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 ire.

(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.

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

ingers, 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 ire hazard.

(4) Do not install the machine in areas with high dust or moisture levels, beside on open window or close to a

humidiier 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 ire.

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-itting any parts do not use excessive force, especially when itting 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 luorescent 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 ield 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 classiied as “anti-static”

can generate electrical charges suficient to damage ESDs.

5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges suficient 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 loor, can generate static

electricity suficient to damage an ESD.
