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 re, 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 Movement
• It is necessary to remove the products when making the service of products put on the wall. At that time,
hold the product by two or more persons to prevent the product from dropping or a person from falling down.
1-2. Cautions during disassembling and assembling
1. When doing repairs, make sure that power plug is pulled out to insure safety.
2. Make sure that parts and 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 ame-resistance and anti-voltage properties.
When replacing parts, always use parts supplied from the factory.
4. After nishing 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 location that was worked on.
5. Be sure to use an earth band (wrist band) during repair and inspection.
6. Aluminum is used for this product as materials. During assembling and disassembling, be careful not to mistake the
type of screws. Depending on the screw used, the screw hole is damaged and parts may be unable to be xed
properly.
CAUTION: Never remove the two tension plates at the top and
bottom because they x a spring.
