1. As a rule, perform schedule servicing every 500,000 prints.
2. Before setting out for a visit, check the service book, and take parts for which replacement is expected.
3. If cleaned with alcohol, each charging wire must be checked to make sure that it is fully dry (solvent) before putting it back in the machine.
4. If left alone for a long time in an area subject to dust, humidity, or oil smoke, the power plug can collect dust, which will absorb moisture to suffer an insulation
fault, turning into a possible source of fire.
Be sure to disconnect it on a periodical basis, and clean it and the area around the power outlet using a dry cloth.
