Such components are commonly called Electrostatically Sensitive (ES) Devices or ESDs. Examples of typical ESDs are: integrated circuits,some feld effect transistors, and semiconductor chip components.The techniques outlined below should be followed to help reduce the incidence of component damagecaused 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 classifed as anti-static can generate electrical charges suffcient to damage ESDs.5.Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges suffcient 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 ones foot from a carpeted foor, can generate static electricity suffcient to damage an ESD.Product OverviewService Manual2-1Samsung Electronics2.1 Product Summary 38 / 38 ppm Network-ready CMFP 20K/15K Black/Color toner 30K CMYK Imaging unit 100K ITB Machine Life : 1,000K or 5 Years Paper handling : Maximum 2,720 Sheets Paper Capacity : Finisher with stapler and offset stacking : 100sh DADF 160 GB HDD High Performance CCDM Easy to install ( CRU & Option ) Color Graphic Touch-Screen LCD Low Cost per Page Direct USB Giga-bit Network2.
