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.
✍

• An interface cable is not a standard accessory. Please purchase
an appropriate cable according to the interface you intend to
use.
• The power cord may differ slightly from this figure depending
on the country where you purchased the 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.

Installing the Optional Multi-function Feeder
The optional multi-function feeder (MFF) is useful to print a lot of
envelopes or transparencies. The MFF can hold and deliver 100
sheets of paper or 30 envelopes.

Notice:
When using paper, do not leave the paper in the multi-function
feeder for a long time. It may cause waving of paper and dropouts in
printing.
Because the MFF does not have a mechanism that detects the
physical size of paper in use, you must inform the printer of the
paper size. Use the MFF paper size menu to select a paper size which
equals the size of paper loaded in the MFF.
To install the multi-function feeder, follow these steps:
Notice:
Be sure that the printer is turned off before installing or removing
the multi-function feeder.
1. Open the front cover.
☞ ☞

DIGITAL Laser Printer LN15 User Manual 1-16
2. Fasten the feeder to the
printer. Insert the left and
right supports and hooks of
the multi-function feeder
into the corresponding
openings at the front of the
printer so that the hooks
catch the pins firmly.
3. Connect the feeder cable.
Connect the feeder cable to
the connector at the right
side of the printer. Orient
the arrow mark of the
cable’s connector right.
Notice:
To avoid paper jams or other feeding errors, make sure that each of
the left and right hooks securely hangs on the pin.
Connecting the Power Cord
This printer comes equipped with one of the two voltage ratings:
• 120 VAC (such as for the USA)
• 220 to 240 VAC (such as for Europe)
The manufacturer’s nameplate on the back of the printer indicates this
rating. Confirm that the rated voltage of your printer matches the voltage
of your power outlet.
1. Check that the printer is
turned off. The “O”-marked
side of the switch should be
depressed.
2. Plug the female end of the
power cord into the
connector on the left back of
the printer.

3. Plug the male end into a
wall outlet.
Caution:
For your safety, use only a properly grounded outlet. To avoid possible
electromagnetic interference or power supply problems, do not use an
extension cord.
This section explains how to connect the printer to your computer via
the parallel interface.
Notice:
The following restrictions apply to interface cables:
• To comply with regulations for radio frequency emissions, use only
shielded cable for computer-to-printer communications.
• The length of the parallel interface cable must be 3 meters (10 feet) or
less.
About Interfacing
You can connect the printer to your computer using a standard parallel
interface. Many computers have a parallel interface port. However, if
your computer does not have the parallel interface port, or for printers
used in a network, the following optional interfaces
are available.

Connecting the
Printer to Your
Computer

DIGITAL Laser Printer LN15 User Manual 1-18
• Serial (RS-232C/422A)
Use a serial interface if the printer is not near the computer. Many
computers have both parallel and serial interface ports. Serial
communication can operate up to 15 meters (50 feet). Parallel
communication is normally limited to 3 meters (10 feet).
• LocalTalk
Use the LocalTalk interface if the printer is connected to a Macintosh
computer.
• Ethernet
Use the Ethernet interface if the printer is used in a network
environment.
Notice:
The DIGITAL Laser Printer LN15N-A and LN15N-B are equipped with
an Ethernet interface.
Connecting to the Parallel Port
This printer does not come with a parallel interface cable. You can use a
standard Centronics interface cable (sold separately) for this purpose.
Your dealer can advise you on the cable you require.
Notice:
Be sure the printer is turned off before connecting the interface.
To make the connection, plug
the cable connector into the
parallel interface port on the
back of the printer. Secure the
connector with the wire clips.
Plug the other connector into
your computer’s parallel port.
