1. COMPLIANCE OF SAFE REPAIR
Be sure to read this Service Manual before providing services. In the PLUS Copyboard, full consideration is
taken to ensure the safety for a fire, electric shock, injury, harmful radiation, and substance. Therefore, observe
the notice described in this Service Manual so that the safety is kept when providing services. Moreover, be sure
to observe the notice described in the User’s Manual.
Pay attention to the following during service inspection.
1-1. Cautions during Product Displacement
• It is necessary to remove the products when making the service of products put on the wall. At that time, hold
the products by two or more persons to prevent the products from dropping or a person from falling down.
1-2. Cautions during Disassembling and Assembling
1. This equipment contains parts under high voltage. When doing repairs, make sure that power plug is pulled
out to insure safety.
2. Make sure that parts, screws and wiring, etc. are returned to their original positions. Tube, tape and other
insulation materials have been used for safety reasons. The internal wiring has been designed to avoid
direct contact with hot parts or parts under high voltage when using clamps or other tools.
3. The parts used in this device have special safety features such as flame-resistance and anti-voltage proper-
ties. When replacing parts, always use parts supplied from the factory.
4. After finishing operations make sure that all parts and wires have been returned to their original position and
that there has been no deterioration of the area around the portion that was worked on.
5. Pay attention to static electricity when handling electronic parts on a board.
