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.
