3. Installation

3.1 Conditions for Installation Laser beam printer is likely influenced by the environment of set-up location.

IF Printer was set up at the inappropriate location, the printer may not perform the characteristic functions as expected. Therefore, the following factors should be taken into consideration prior to deciding where to set.

(1). Environmental Conditions

Printer should not be set up at the locations referred to by the following

items (a) through (d) specifying the inappropriate locations for set-up.

(a). Likely to receive the direct sunbeam or similar light.

(For example, window side)

(b). Likely to cause the big difference in temperature and humidity between

the maximum and minimum level. (Normal operation environment is

within 10 ~ 35 , 20 ~ 80%RH and without any condensation.)

(c). Likely to receive cold wind from air-conditioner or worm wind from

heater, or to receive direct radiant heat. (d). Likely to cause much dust or have corrosive gas like ammonia. (e). Users to select the location of good ventilation and set a printer on the

flat surface.

(f). Users to check the maximum tilt of set-up location to be within 1 .

(2). Basic Layout of Printer Set-Up Location

Fig.3-1 shows the basic layout of printer set-up location suitable for the smooth operation and maintenance of printer.
