This section will help you:
• Choose a suitable location for the printer
• Identify the parts of the printer as you unpack it
Picking a Suitable Location
The first step is to pick a suitable location for your printer. For peak
performance and usability, follow these guidelines:
• Place the printer on a
sturdy, level surface.
• Choose a room that is well
ventilated and free of
excessive dust. Leave space
on either side of the printer
for proper ventilation.
• To avoid exposing the
printer to extremes of
temperature, do not put the
printer in direct sunlight or
near a heater. Ideal room
temperature is from 10°C
to 35°C (50°F to 95°F).
Humidity should be
between 20% and 80% RH
(no condensation).
• Use a grounded AC power
outlet. Do not use a three-
pronged adapter in an
ungrounded outlet.

DIGITAL Laser Printer LN15 User Manual 1-5
• Use only the power cord
furnished with the printer.
Do not use an extension
cord.
• Do not touch any
connector contacts and
corona wires to avoid
possible electrostatic
damage to the printer.
• Do not use a circuit shared
with equipment that causes
electrical noise, such as
motors.
• Do not use a circuit shared
with equipment that uses a
lot of power, such as a
copier or a coffee maker.
Unpacking and Checking Your Printer
As you unpack the printer, check each item carefully for damage. If
you find damage, notify your dealer. Check also that you have
received all the items.
This printer comes with everything you need except an interface
cable. If you do not yet have a cable, you must purchase one before
you can connect the printer to your computer.
Important:
Save the original carton and packing materials in case you need to
store or transport your printer.

This section describes how to assemble the printer and connect the
power cord after choosing a suitable location for the printer and
checking that you received all the parts.
Preparing the Print Unit and Installing the Toner Cartridge
This printer is shipped with the print unit mounted and protective
materials attached. Be sure to remove the two protective materials
from the print unit. This operation is possible with the print unit
mounted. First prepare and install the following two components:
• Print unit (photoconductor drum, developing unit, etc.)
• Toner cartridge
The toner cartridge first installed after you purchase the printer will
last about 2,500 printed pages under the condition of 5% coverage
on A4 paper. The succeeding toner cartridges last about 5,000
printed pages each.
Notice:
Do not touch any connector contacts and corona wires to avoid
possible electrostatic damage to the printer.
Be careful with the print unit’s drum (the green surface). The drum
is easily damaged by contamination or by exposure to light for more
than three minutes. Follow these guidelines:
• Never touch or scratch the drum surface.
• When the print unit is not in the printer, store it in a dark place or
cover it with a clean sheet of paper.
• When the print unit is in the printer, keep the printer top cover
closed. If you must work inside the printer for more than three
minutes, remove the print unit with the toner cartridge mounted
and store it in a dark place.
