Precautions
Precautions
Follow all warnings, precautions and maintenance as
recommended in this user’s guide to avoid injury, fire, electric
shock, and to maximize the life of your projector.
Warning—Do not look into the projector’s lens when the lamp is
on. The bright light may hurt your eyes. Never let children look
directly into the lens when the light is on.
Warning—Do not look into the laser beam or shine it into others’
eyes when using the remote control as a laser pointer. Laser light
seriously damage eyes.
can
Warning—Make sure that the projector is grounded properly by
connecting the power cord to a grounded electric AC outlet. Always
use the power cord that comes with your projector. Do not use an
ungrounded adapter with the grounded plug.
Warning—Except for the lamp cover, never open or disassemble
the product as this may cause electric shock. Dangerous electrical
voltages inside the projector can cause severe injury.
Warning—Do not overload wall outlets, extension cords, or multiplug receptacles as this can result in a risk of fire or electric shock.
Place the unit near an easily accessible wall socket. Do not place
the cord where it may be stepped on or become a tripping hazard.
Warning—To reduce the risk of fire or electric shock, do not
expose this product to rain or moisture. Do not place drinks on top
of the projector. Spilled drinks can cause an electric shock hazard
and can also damage the projector. If liquid or any solid object falls
into the cabinet, have the projector checked by a qualified
technician before operating it further.
Warning—Do not place your hands or objects near the ventilation
slots. The air coming out of the slots is hot. Do not block the
ventilation slots or place anything near these slots that may block
the free flow of air. Blocked ventilation may cause internal heat
build-up and cause picture degradation or damage to the projector.
Warning—The ventilation fan continues to operate after the
projector is powered off and until the projector is sufficiently cooled
down. Do not unplug the power cord until the fan stops.
Warning—Keep the plastic packaging material away from children,
especially small children. The plastic bags may result in death by
suffocation.

Do’s and Don’ts
Precautions
Do:
•Operate the projector in a well-ventilated room to avoid a
buildup of ozone from the projector’s high-performance lamp.
•Turn off the projector before cleaning.
•Use a dampened soft cloth to clean the display housing.
•Disconnect the power plug from AC outlet if the projector is not
being used for a long period of time.To disconnect the cord, pull
it out by the plug. Do not pull on the cord.
•Use lint-free gloves or finger cots when changing the lamp.
Never touch a lamp with your bare hands. The invisible residue
from the natural oil on your hands may shorten the lamp life.
Don’t:
•Place the projector on an unstable cart, stand, or table. If the
projector falls, it may be seriously damaged.
•Operate the projector near paper, cloth, or other combustible
material, or in proximity to inflammable substances, such as
paint thinner. Never operate the projector if covered with
combustible materials. The projector gets hot and combustible
and inflammable materials may catch fire.
•Use abrasive cleaners, waxes or solvents to clean the
projector.
•Use under the following conditions:
— In extremely hot, cold or humid environment.
— In areas susceptible to excessive dust and dirt.
— Near any appliance generating a strong magnetic field.
— In direct sunlight.
— Near any heat source, such as radiators, heat registers,
stoves, or other products (including amplifiers) that produce
heat.
— In a smoky area. Smoke residue may cause buildup on
critical parts, including the lens.
Attempt to service the projector yourself. Opening or removing
the coverings of the internal components may damage them
and void your warranty.

Maintenance
The projector needs proper maintenance. Keep the lens clean
because dust, dirt, or spots will project on the screen and diminish
image quality.
Keep the projector housing clean to maintain its appearance.
Before cleaning the lens or housing, always turn off the power first
and unplug the power cord.
Note that only the lamp is replaceable. If any other parts need
replacing, contact your dealer or qualified service personnel.
Warning—Never open any of the covers on the projector except
the lamp cover. Dangerous electrical voltages inside the projector
can cause serious injury. Do not attempt to service the projector
yourself. Refer all servicing to qualified service personnel.
Cleaning the Lens
1. Turn off the projector and let it cool down. Make sure the lens is
also cool.
2. Wipe the lens in a circular motion with lens cleaning paper.
Do not touch the lens with your hands.
Always keep the lens cap on the lens when the projector is not
in use.
Cleaning the Projector
1. Turn off the projector and let it cool down.
2. Unplug the power cord.

Changing the Lamp
Precautions When Changing a Lamp
The projector automatically monitors the lamp life. As the lamp
reaches the end of its life, the image becomes darker and the color
hues weaker. The projector’s Lamp LED turns red to let you know
that the lamp must be changed soon before it fails completely.
When you see the red Lamp LED, please change the lamp as soon
as possible.
Note that lamp lifetimes vary according to the operating
environment and type of use. Lamp lifetimes are not guaranteed
and some lamps may end their lifetimes earlier than others.
NOTE: To order a new replaceable lamp module, please go to
www.xeroxprojectors.com.
•The lamp module is the only user-replaceable part in the
projector. To prevent electric shock, do not open the projector
case.
•Always wear protective gloves and eyeglasses when fixing or
replacing the lamp. Lamp contains mercury.
•To reduce the risk of personal injury, do not drop the lamp
module or touch the lamp bulb at any time. The lamp module
may explode if handled incorrectly, and may shatter and cause
injury if dropped.
•The lamp is hot! If you touch the lamp, you may scald your
fingers. Allow the projector to cool down at least 45 minutes
before opening the lamp compartment or changing the lamp.
•In the event that the lamp is dropped or broken, and explodes
or bursts, please leave the area immediately and ventilate it for
at least 30 minutes.
•Do not operate the projector with the lamp cover removed.
•Do not attempt to reuse an old lamp. An old lamp may explode
if reused.

projector. Also visit our web site at www.xeroxprojectors.com for
additional technical information.
Problem: No image appears on the screen.
Check for one of these possible problems:
•Are the cables loose or not plugged in securely? Inspect
the cable connections. Make sure the cables are plugged in
securely.
•Are any of the pins on the cables bent or broken? Inspect
the pins on the cable plugs to make sure none of the pins are
bent or broken.
•Is the projection lamp securely installed? Check that the
projection lamp is securely installed, especially if you just
changed it. See the section “Changing the Lamp” on page 28
for details about the lamp installation.
•Is the power on? Check that the projector’s power switch is
turned on and that the power cord is plugged in securely to a
working power outlet. If you are using a power strip, make sure
it is turned on and plugged in.
•Is the lens cap still on? Make sure you have removed the
lens cap from the lens at the front of the projector.
•Are the Brightness and Contrast set incorrectly? Adjust the
Brightness and Contrast until a picture appears. See “Image
Menu” on page 20.

Problem: Image is out of focus.
Try one of these possible solutions:
•Adjust the focus ring on the projector. Turn the focus ring until
the image comes into focus.
•Make sure the distance between the projector and the screen is
between 1.2m and 10.0m. See “Adjusting Projection Image
Size” on page 15 for details.
Problem: When the projector is connected to a DVD
player, playing a film with a 16:9 aspect ratio makes the
image looks stretched out.
Try one of these possible solutions:
•Reset your DVD player to display at a 4:3 aspect ratio. See the
DVD player user’s guide for the steps to adjust its aspect ratio.
•Using the OSD Menus, go to the Image Menu and select a new
Aspect Ratio. Change it to 4:3.
Problem: The colors of the projected image look different
than the colors of the image on the computer screen.
Use the OSD Image and Video menus to adjust the colors.

Maintenance
Problem: Image is reversed or inverted.
Use the OSD Advanced Menu to change the Rear or Ceiling option
to display the image properly.
Problem: No sound.
Make sure the audio cables and other cables are connected
properly.
Problem: Remote control does not work.
Check for one of these possible problems:
•Are you too far from the projector? The remote control has a
range of about 10ft (3m) and needs to be within 20° of the
sensor. Move closer to the projector and try again.
•Is anything blocking the infrared sensors on the projector?
Make sure the infrared sensors are not covered or blocked
from receiving signals from the remote control.
•Are the batteries in the remote control dead? Replace the
batteries in the remote control.
Problem: Lamp burns out or makes a popping sound.
When the lamp reaches its end of life, it may burn out and may
make a loud popping sound. If this happens, do not attempt to turn
on the projector until the lamp module has been replaced. See
