We have determined as a participating company in the International Energy Star
Program that this product is compliant with the standards laid out in the
International Energy Star Program.
About the International Energy Star Program
International Energy Star Program has as its basic goals the promotion of efficient
energy use and the reduction of the environmental pollution that accompanies
energy consumption by promoting the manufacture and sale of products that fulfill
program standards.
International Energy Star Program standards require that printers come equipped
with a “Sleep Mode”, allowing the device to enter a wait state where energy
consumption is automatically reduced to a minimum after a certain amount of time
elapses since it was last used.
This product is equipped with the following features as a result of its compliance
with International Energy Star Program standards.
• Sleep Mode
The device automatically enters “Sleep Mode” when 90 minutes have passed
since the device was last used. The amount of time of no activity that must pass
before “Sleep Mode” is activated may be lengthened. For more information see
“Auto Shutoff Function”.
• Paper Recycling
The Energy Star Program encourages the use of environmentally friendly
recycled paper. Your sales or service representative can provide information
about recommended paper types.
NOTE
• This Operation Guide applies to models KM-P4845w and KM-P4850w. For the
purposes of this guide, KM-P4845w is a 2.6 ppm (prints per minute) printer (A0
size) while KM-P4850w is a 3 ppm printer (A0 size).
• This Operation Guide contains content for both the inch and metric specification
models of the printer. When messages displayed on the printer’s display differ

INSTALLATION PRECAUTIONS
■ Environment
CAUTION
• Avoid placing the printer on or in locations which
are unstable or not level. Such locations may
cause the printer to fall down or fall over. This
type of situation presents a danger of personal
injury or damage to the printer. ............................
• Avoid locations with humidity or dust and dirt. If
dust or dirt become attached to the power plug,
clean the plug to avoid the danger of fire or
• Avoid locations near radiators, heaters, or other
heat sources, or locations near flammable items,
to avoid the danger of fire. ...................................
• To keep the printer cool and facilitate changing of
parts and maintenance, allow access space as
shown below.
Leave adequate space, especially around the left
right and rear covers, to allow air to be properly
ventilated out of the printer...................................
Rear:

• Always use the caster stoppers to stabilize the
printer once it is in place to keep it from moving
and/or falling over and causing injury. ..................
Other precautions
• Adverse environmental conditions may affect the safe
operation and performance of the printer. Install in an
air-conditioned room (recommended room temperature:
around 68°F [20°C], humidity: around 65%RH) and
avoid the following locations when selecting a site for
the printer.
.
Avoid locations near a window or with exposure to
direct sunlight.
.
Avoid locations with vibrations.
.
Avoid locations with drastic temperature fluctuations.
.
Avoid locations with direct exposure to hot or cold air.
.
Avoid poorly ventilated locations.

• If the floor is delicate against casters, when this product
is moved after installation, the floor material may be
damaged.
• During printing, some ozone is released, but the amount
does not cause any ill effect to one's health. If, however,
the printer is used over a long period of time in a poorly
ventilated room or when making an extremely large
number of copies, the smell may become unpleasant.
To maintain the appropriate environment for printing
work, it is suggested that the room be properly
ventilated.
■ Power supply/Grounding the printer
WARNING
• DO NOT use a power supply with a voltage other
than that specified. Avoid multiple connections in
the same outlet. These types of situations
present a danger of fire or electrical shock. .........
• Plug the power cord securely into the outlet. If
metallic objects come in contact with the prongs
on the plug, it may cause a fire or electric shock.
• Always connect the printer to an outlet with a
ground connection to avoid the danger of fire or
electrical shock in case of an electric short. If an
earth connection is not possible, contact your
service representative. .........................................
Other precautions
• Connect the power plug to the closest outlet possible to
the printer.
• The power supply cord is used as the main disconnect
device. Ensure that the socket/outlet is located/installed
near the equipment and is easily accessible.
■ Handling of plastic bags
WARNING
• Keep the plastic bags that are used with the
printer away from children. The plastic may cling
to their nose and mouth causing suffocation........

PRECAUTIONS FOR USE
■ Cautions when using the printer
WARNING
• DO NOT place metallic objects or containers with
water (flower vases, flower pots, cups, etc.) on or
near the printer. This type of situation presents a
danger of fire or electrical shock should they fall
• DO NOT remove any of the covers from the
printer as there is a danger of electrical shock
from high voltage parts inside the printer. ............
• DO NOT damage, break or attempt to repair the
power cord. DO NOT place heavy objects on the
cord, pull it, bend it unnecessarily or cause any
other type of damage.
These types of situations present a danger of fire
or electrical shock. ...............................................
• NEVER attempt to repair or disassemble the
printer or its parts as there is a danger of fire,
electrical shock or damage to the laser................
• If the printer becomes excessively hot, smoke
appears from the printer, there is an odd smell, or
any other abnormal situation occurs, there is a
danger of fire or electrical shock. Turn the main
switch OFF ( ) immediately, remove the power
plug from the outlet and contact your service
• If anything harmful (paper clips, water, other
fluids, etc.) falls into the printer, turn the main
switch OFF ( ) immediately. Next, remove the
power plug from the outlet to avoid the danger of
fire or electrical shock. Then contact your service
• DO NOT pull the power cord when removing it
from the outlet. If the power cord is pulled, the
wires may become broken and there is a danger
of fire or electrical shock. (ALWAYS grasp the
power plug when removing the power cord from
the outlet.) ............................................................
• ALWAYS remove the power plug from the outlet
when moving the printer. If the power cord is
damaged, there is a danger of fire or electrical
• If the printer will not be used for a short period of
time (overnight, etc.), turn the main switch OFF
( ).
If it will not be used for an extended period of
time (vacations, etc.), remove the power plug
from the outlet for safety purposes during the
time the printer is not in use. ................................
• When moving the printer, turn the leveler bolts to
keep them away from the floor. ............................
• For safety purposes, ALWAYS remove the power
plug from the outlet when performing cleaning
• If dust accumulates within the printer, there is a
danger of fire or other trouble. It is therefore
recommended that you consult with your service
representative in regard to cleaning of internal
parts. This is particularly effective if accomplished
prior to seasons of high humidity. Consult with
your service representative in regard to the cost
of cleaning the internal parts of the printer. ..........
• DO NOT remove or connect the power plug with
wet hands, as there is a danger of electrical
