1 Safety Precautions 1.1. General Guidelines 1. IMPORTANT SAFETY NOTICE There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Circuit Board Layout, Exploded Views and Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent X-RADIATION, shock, fire, or other hazards.
1.2. Before Repair and Adjustment Disconnect AC power to discharge AC capacitor (in SMPS Module) as indicate below diagram through a 10 Ω, 10 W resistor to ground. Figure 1-2 Caution: DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices. After repairs are completed, restore power gradually using a variac to avoid overcurrent.
1.4. Power Supply using SMPS Module This model uses Switching Mode Power Supply (SMPS Module) to provide the power supply to the unit. Here is the supplied part no. for the Module 1) N0AB2GP00003 Figure 1-3...
1.5. Safety Parts Information Safety Parts List: There are special components used in this equipment which are important for safety. These parts are marked by in the Schematic Diagrams, Exploded View & Replacement Parts List. It is essential that these critical parts should be replaced with manufacturer’s specified parts to prevent shock, fire or other hazards.
2 Warning 2.1. Prevention of Electrostatic Discharge (ESD) to Electrostatically Sensi- tive (ES) Devices Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Elec- trostatically Sensitive (ES) Devices. The following techniques should be used to help reduce the incidence of component damage caused by electrostatic discharge (ESD).
2.3. General description about Lead Free Solder (PbF) The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this equipment in considering the globally environmental conservation. The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin (Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30 degrees C (86°F) more than that of the normal solder.
ble cable, cut off the antistatic FFC. Figure 2-1 2.5. Grounding for electrostatic breakdown prevention • As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working environ- ment. Repair in the working environment that is grounded. 2.5.1.
