During copying, some ozone is released, but the amount does not cause any ill effect to one's
health. If, however, the machine is used over a long period of time in a poorly ventilated room
or when making an extremely large number of copies, the smell may become unpleasant. To
maintain the appropriate environment for copy work, it is suggested that the room be properly
ventilated.
