1 GENERAL PRECAUTIONS
1.1.
Safety Precautions
1. Before servicing, unplug the power cord to prevent electrical shock hazard.
2. When replacing parts, use only manufacture’s recommended components for safety.
3. Check the condition of power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the wire dressing, insulation barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, perform the following electrical tests to prevent shock hazard.
6. The power supply unit in this scanner contains dangerous levels energy.
1.2.
Electrical Tests
1. Unplug the power cord and check for continuity between the earth ground connection on the plug and the metal cabinet.
There should be zero ohm resistance found.
2. With the unit unplugged, short the AC Live-Neutral of the plug with a jumper wire. 
3. Turn ON the power switch.
4. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part, such
as screwheads, etc.
Note
   Some exposed parts may be isolated from the chassis by design. They read infinity.
5. If the measurement is less than 1 M
, there may be a danger of electric shock.
Note
   This hazardous condition must be corrected before the unit is returned to the end user. 
1.3.
Standard for Repair Service
Repair service shall be provided in accordance with repair technology information such as service manual
so as to prevent fires, injury or electric shock, which can be caused by improper repair work.
1. When performing repairs, neither the products nor its parts or components shall be modified.
2. If cable assembly is supplied as the smallest unit when servicing, make sure to replace
the cable assembly.
