ensure the proper operation of the printer. Consider the following
points before installing the printer:
●
Install in a well-ventilated, dust-free area.
●
Install on a hard, flat and continuous surface, with all four printer
feet level. Do not install on carpet or other soft surfaces.
●
Ensure adequate power is supplied. Printer power requirements
are listed in Table 1-5. (Uninterruptable power supplies (UPSs)
are not recommended.)
●
Install where temperature and humidity is stable, away from water
sources, humidifiers, air conditioners, refrigerators, or other major
appliances.
●
Install away from direct sunlight, open flames, or ammonia fumes.
If the printer is placed near a window, make sure the window has
a curtain or blind to block any direct sunlight.
●
Install with enough space around the printer for proper access
and ventilation.
●
Install away from the direct flow of exhaust from air ventilation
systems.
