excessive vibration.
If the printer is locate d in a cold room that is rapidly heated, or if t he prin te r is moved
from a cold place to a warm, humid plac e, condensation may occur w ithin the printe r,
degrading print quality. If this occurs, allow the printe r to adapt to the environment
for about one hour before use.
Away from water.
If using a humidifier or water v aporizer in the room with the printer, use only purified
or distilled water. Impuriti es in the water may be released into the air, where they can
accumulate inside the printer and cause degraded printer output.
At an altitude of 0–8202' (0–2500 m).
Near your computer—6.5' (2 m) or less for an IEEE 1284 bidirectional pa rallel c on-
nection; cables for other connections may be longer.
Close to an easily accessible grounded power supply on an exclusively dedicated
power outlet.
WARNING!
Do not connect the groun dwire to gas or water pipes or gro unding for telephone s.
Not connected to the same electrical outlet as noise-generating equipm ent . I f the
print er is connecte d to t he sa me circuit use d by ot her high-c urrent mac hines, such as a
copier or air co nditione r , o r to a n ele ctrically noisy machine , low volta ge or noi se may
cause overheating, com puting er rors resulting in data loss, a nd improper performance.
In a well-ventil ated area, but away from wind.
With enough space to allow adequa te ventilation and easy servicing.
