Select A Site
Select A Site
Select a printer site that meets all of the following requirements:
•
Cabinet models: Permits complete opening of the printer cover and both
doors of the floor cabinet. Allows at least three feet of clearance behind
the printer. (This permits air to circulate freely around the printer and
provides access to the paper stacking area.)
•
Pedestal models: Permits complete opening of the printer cover and
good access to the paper areas at the front and rear of the printer.
•
Has a standard power outlet that supplies 88-135 Volts AC or
178-270 Volts AC power, at 47 to 63 Hz. The printer automatically senses
and adjusts itself to conform to the correct voltage range.
•
Is relatively dust-free.
•
Has a temperature range of 10° C to 40° C (50° F to 104° F) and a
relative humidity from 15% to 90% non-condensing.
•
Is located within the maximum allowable cable length to the host
computer. This distance depends on the type of interface you plan to use,
as shown in Table 2.
