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

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
