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.
4)

Plastic parts and ink may be deformed, discolored, or may
undergo qualitative change.
It may cause a breakdown or copy dirt.
5)
Place which is full of organic gases such as ammonium
The organic photoconductor (OPC) drum used in the machine
may undergo qualitative change due to organic gases such as
ammonium.
Installation of this machine near a diazo-type copier may result
in dirt copy.
6)
Place of much dust
When dusts enter the machine, it may cause a breakdown or
copy dirt.
7)
Place near a wall

If intake and exhaust of air are not properly performed, copy
dirt or a breakdown may be resulted.
When installing the machine, make sure that the sides and
back of the machine are at least 11-13/16" (30 cm) away from
any walls.
