2. Installation
The surrounding conditions of the machine affect the machine perfor-
mance greatly. Avoid installation to the following places.
Avoid high temperature, high humidity, low temperature, and low
humidity. Avoid sudden temperature change. (Avoid installation
near a stove, a humidifier, a cooler, etc.)
If not, paper absorbs moisture and dew forms in the machine,
causing paper jam or degraded image quality.
(Use condition: 15 ∼ 30°C, 20% ∼ 85%RH)
For an ultrasonic humidifier, use pure water for it. If top water is
used for an ultrasonic humidifier, mineral components are dis-
persed to be accumulated in the copier, causing copy dirt.
Avoid a dusty place.
If dusts enter the machine, copy dirt or some troubles may occur.
Allow enough space around the copier for proper operation and for
ventilation. (Allow clearances from the walls as shown.)

Ozone is produced during copying at a level which causes no
adverse effect to human bodies. When, however, making a great
volume of copies, it smells a little. It is better to install the copier in
a well ventilated place with a window or a ventilator.
@ If the copier is installed near a window, be careful not to subject
it to direct sunlight.
Avoid direct sunlight.
The plastic parts may be deformed or copy dirt may result.
Avoid a place where there is ammonia gas.
