Unpacking and setting up the Colorwriter
• Report any shipping damage. If there is any evidence of
shipping or handling damage to the Colorwriter packing boxes
or their contents, save the damaged boxes and parts, call the
shipper immediately to file a claim, and notify your authorized
service/support center.
• Do not operate the printer until all packaging materials
(packing tape, spacers, and styrofoam molds) have been
removed.
• Before connecting the printer to a power source, check the
voltage rating label at the back of the printer to ensure that the
printer voltage matches that of the power source.The voltage
rating label is located on the rear of the printer. If the voltage
label is missing, contact the nearest authorized dealer or your
place of purchase.
• Be sure to unravel the power cord prior to plugging it in. Using
it tied up may lead to damage, overheating, a short-circuit, or
fire.
• Be sure to plug the power cord well into the power outlet, as any
flammable material caught between an opening may result in
fire.
• Avoid using an extension cord. If it is unavoidable, be sure to
take the following precautions. Failure to do this may lead to
overheating, fire, or cause flickering due to a drop in voltage.
• Be sure not to exceed the allowed rating current of the
extensioncord.Makesurethat the total ampere rating ofthe
products plugged into the extension cord does not exceed
the extension cord ampere rating.
• Usea short extensioncord.Donot connect severalextension
cords together.
• Be sure to connect the printer to a ground terminal.
• The power cord should be routed so that it is not likely to be
walked on or pinched by items placed on or against it. Pay
particular attention to the plug, the receptacle, and the point
where the cord exits the unit.
• When connecting cables or disconnecting cables from the
printer, make sure that the power switch is in the off position.
• Keep the power cord and cables away from children.
• Do not handle plugs with wet hands.

• Be sure to turn off the power before unplugging or plugging in
the printer power cord or interface cable.
• Be sure to use a surge suppressor on the Colorwriter.
Operating the Colorwriter
• Slots and openings in the cabinet are provided for ventilation.
To ensure reliable operation of the printer and protect it from
overheating, these openings should never be blocked or covered.
• The printer is equipped with a 3-wire grounding type plug,
which has a third (grounding) pin.This plug will fit only into a
grounding-type power outlet. If you are unable to insert the
plug into the outlet, contact your electrician to replace your
obsolete outlet. Do not defeat the purpose of the grounding-
type plug.
• If the printer will not be used for a long period of time, turn the
power off and unplug the power cord.
• Unplug the printer from the wall outlet before cleaning. Use a
damp cloth for cleaning. Do not spray liquid cleaners or aerosol
cleaners directly on the cabinet or the openings, as the spray
could penetrate inside the printer and contaminate internal
parts.
• Never push objects of any kind into the printer through
openings in the enclosure, as the objects may touch dangerous
voltage points or short out parts. This could cause a fire or
electrical shock.
• Never spill any liquids into the printer.
• The outlet should always be free from any obstacles so as to
allow easy access.
• When unplugging the printer, always disconnect the power cord
by pulling on the plug, not the cord itself.

Colorwriter LSR 2000 Printer
Service Guide
• Any misuse of electrical equipment is hazardous. Do not allow
children to handle power cords or cables.
• Avoid operating the printer when the waste toner bottle and/or
silicone oil bottle is not installed; otherwise the printer may be
damaged.
• Do not attempt to modify the printer.
• Do not remove the warning or instruction labels on the printer.
• Do not dispose of the used waste toner box or the silicone oil
box into a fire.
Network precautions
• Never alter an existing network without permission from the
network administrator.The Colorwriter will probably be
connected to an existing Local Area Network (LAN) based on
Ethernet

hardware. The network is the link between the
customer’s computer other equipment. Never disturb the LAN
by breaking or making a network connection, altering
termination, installing or removing networking hardware or
software, or shutting down networked devices without the
knowledge and express permission of the system or network
administrator or the shop supervisor.
• Never enter an IP address in Colorwriter Network Setup. Only
the network administrator should enter an IP address on a
network device. Assigning a Colorwriter an incorrect IP address
cancause unpredictable errors onany or alldevices connected to
the network.

Those who are particularly sensitive to ozone odor may rarely feel
sick if exposed to it excessively. To avoid this, make sure that the
following measures are taken.
• Install the printer in a well ventilated room.
• Avoid using multiple laser printers simultaneously.
• Avoid facing the exhaust port directly toward users.
• Replace a disposable ozone filter after about 60,000 prints.
• Avoid using the printer without a filter.

Toner safety
Toner is a harmless substance. If you get toner on your skin or
clothes, remove as much as possible with a dry tissue and then wash
it with cold water. Do not use hot water; the toner may gel and
become hard to remove.Toner easily decomposes vinyl material;
therefore you should not let it come into contact with this material.
