CHAPTER 3 INSTALLATION
1. CONDITIONS REQUIRED FOR INSTALLATION
Any Laser beam printer is likely to be influenced by the environment of the set-up location. If
the printer is set-up in an inappropriate location, the printer may not perform as expected.
Therefore, the following factors should be taken into consideration before deciding where to
set-up the printer.
1.1. Environmental Conditions
The printer should not be set up in the locations referred to in the following items (1) through
(8) which specify inappropriate locations for set-up.
(1) Where it is likely to receive direct sunlight or similar light. (For example, next to a
window)
(2) Where it is likely to suffer a big difference in temperature and humidity between the
maximum and minimum levels. (Normal operation environment is within 10
q
C
a
32.5

a
80%RH and without any condensation.)
(3) Where it is likely to be in a draft of cold air from an air-conditioner or warm air from a
heater, or to receive direct radiant heat.
(4) Where it is likely to be excessively dusty or be subject to corrosive gases such as
ammonia.
(5) Where it is likely that an ultrasonic humidifier will be used.
(6) Where it is likely to have poor ventilation.
(7) Where it is likely to have unstable conditions such as when the set-up table is not strong
enough.
(8) Where it is likely to be tilted (angle from the horizontal should not be greater than
r
