1. Warning for servicing
1) Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.
Avoid complex wiring, which may lead to a fire or an electric shock.
2) If there is any abnormality such as smoke or an abnormal smell,
interrupt the job and disconnect the power plug.
It may cause a fire or an electric shock.
3) Be sure the machine is properly grounded. Failure to ground the
machine properly may result in an electric shock or fire.
To protect the machine and the power unit from lightening, ground-
ing must be made.
ing must be made.
4) When connecting the ground wire, never connect it to the following
points as it may cause an explosion, fire, or an electric shock:

2) Place of much vibrations
It may cause a breakdown.
3) Poorly ventilated place
An electro-static type copier will produce ozone inside it.
The quantity of ozone produced is designed to a low level so as not
to affect human bodies. However, continuous use of such a
machine may produce a smell of ozone. Install the machine in a
well ventilated place, and ventilate occasionally.
