Positioning the Projector
The location in which you choose to set up your projector
depends on the size of the room and your presentation style.
❏ Place the projector on a sturdy, level surface, within this
distance from the screen:
3.3 to 36 feet in Wide mode
3.9 to 43.2 feet in Tele mode
(see page 7 for more information on these modes)
❏ Make sure there is plenty of space for ventilation around and
under the projector.
❏ Make sure the projector is within 6 feet of a grounded
electrical outlet or extension cord, and within 5 feet of your
computer and/or video source.
❏ Place the projector directly in front of the center of the
screen, facing it toward the screen squarely. Otherwise, your
image will not be square.
Note
:
It’s best to position the screen directly in front of the room. If it’s
placed diagonally in a corner, it’s much more difficult to aim the
projector at the screen correctly and get a square image.
Most presenters find it convenient to place the screen in the
front of the room with the projector back near the front of the
audience, leaving ample room between the screen and
projector to get a good-sized image. Then the presenter can
stand in front of the room, facing the audience and control the
equipment from there.
Use the figure below as a guideline to help you determine how
far from the screen to place the projector. Your image size may
not exactly match these sizes; its actual size depends on
whether you have adjusted the image size setting (using
keystone correction or the
Wide/Tele
button).
If you have to raise the projector by adjusting its feet
(described on page 7), you’ll need to square-up the sides of
image by pressing the
Keystone
button (also on page 7).
If you’ll be projecting from overhead, you’ll get the bestlooking picture by mounting the projector upside-down,
parallel to the ceiling, with the bottom of its lens level with the
top of the screen. (You’ll also need to select ceiling projection
mode in the projector’s Advanced menu.)
Displaying an Image
Once you’ve connected the projector to your computer or
other equipment, you’re ready to turn on the projector, adjust
the image, and give your presentation.
Turning On Your Equipment
Make sure your projector and other equipment are set up and
connected correctly. Then plug in and turn on your
equipment, as described below.
Note:
If you have more than one source connected, you may have to
switch to the one you want to use, as described on page 8.
Follow these steps to plug in and turn on your equipment:
1. If you’re projecting video, first plug in and turn on your
VCR, DVD player, or other video source. (If you’re
projecting from a computer, go to step 2.)
2. To turn on the projector, first connect one end of the power
cord to the projector’s power inlet on its left side.
4 ft.8 ft.40 ft. distance from
the screen
When projecting from a table, the ideal arrangement is to set
the projector flat on its surface with the base of the lens at
about the level of the bottom of the screen. This delivers the
best-looking picture.

Never look into the lens when the lamp is on. This can damage
your eyes, and is especially dangerous for children.
6. If you’re projecting images from a computer, turn on your
computer. In a few moments, you should see your computer
display projected. (If a projected image fails to appear, see
the next section for help.)
Note:
Windows only: If you see a New Hardware Found message saying
that Windows has found a plug-and-play monitor, click Cancel.
Play
7. If you’re projecting video, press the
button. (If a
projected image fails to appear, see the next section for help.)
Once you see your image, turn to page 6 for instructions on
focusing and making other image adjustments.
When you’re done with your presentation, shut down the
projector as described on page 9. Shutting down the projector
correctly prevents premature lamp failure and possible damage
to the projector from overheating.

1. Stand behind the projector. Pull up the blue foot release
levers and lift the front of the projector. This unlocks the
feet.
2. Raise or lower the front of the projector as necessary.
Caution:
To avoid damaging the lens, do not lift the projector by the lens.

4. To fine-tune the height,
rotate the feet clockwise to
raise the projector and
counterclockwise to lower it.

of the lamp and protects the projector from possible
overheating.
Note:
If sleep mode is enabled and the projector has not received any
input signals for 30 minutes, it automatically turns off the
projector lamp and enters “sleep mode.” This conserves electricity,
cools the projector, and extends the life of the lamp. In sleep mode,
the Power light is orange. If you are done using the projector,
unplug the power cord. If you want to start projecting again, press
the Power button on the projector or the remote control.

If you connected a mouse cable to the projector, you can also
use the remote control as a wireless mouse to run your
presentation.
Note:
You can aim the remote control at your projection screen and
reflect the signal back into the sensor on the front of the projector,
but this shortens the operating distance of the remote control.
Installing the Remote Control Batteries
The remote control operates the projector and lets you access
its setup menus. You can also use it as a wireless mouse.
Follow these steps to install the
batteries:
1. Press the tab to release the
battery cover and lift it up to
remove it.
2. Insert the two AA batteries
included with the projector
as shown.
3. Replace the battery cover.
Caution:
When replacing batteries, take the following precautions:
❑ Replace batteries as soon as they run out.
❑ Do not mix old and new batteries.
❑ If the batteries leak, wipe away battery fluid with a soft
cloth. If fluid gets on your hands, wash them immediately.
❑ Remove batteries if you will not be using the remote for a
long period of time.
Using the Remote Control
The remote control lets you access projector features from
anywhere in the room—up to 32 feet away. You must also be
within a 30° horizontal and a 15° vertical angle from the
infrared receiver at the front of the projector. You can use it to
turn the projector on and off, zoom the image, display the
projector menus, and other uses.

Using the Remote Control as a Wireless Mouse
Using the remote control as a wireless mouse gives you more
flexibility; you don’t need to stay near your computer or the
projector to run your presentation.
To use the remote control as a mouse, you must first connect a
mouse cable between your computer and the projector.
Note:
When you connect the mouse cable, your computer mouse is
disabled and you can’t use another external mouse with your
desktop computer. However, you may still be able to use the builtin mouse pointer on a laptop.

Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
❏ To remove dust, use a canister of compressed air to spray the
lens surface, or lightly wipe the lens surface with a soft, dry,
lint-free cloth.
❏ To remove dirt or smears, use lens-cleaning paper. If
necessary, moisten a soft cloth with an alcohol-based cleaner
and gently wipe the lens surface.
Caution:
Be careful not to get alcohol-based cleaner on the projector case.

Cleaning the Projector Case
Before you clean the projector case, turn off the projector and
unplug the power cord.
❏ To remove dirt or dust, wipe the outside with a soft, dry,
lint-free cloth.
❏ To remove stubborn dirt or stains, clean the case using a soft
cloth moistened with water and a neutral detergent. Dry it
using a separate cloth.
❏ Do not use alcohol, benzene, thinner, wax, or other
.
chemicals. These can damage the case.
Cleaning the Air Intake Vent
Clean the air intake vent after every 100 hours of use, or if the
Error
light on top of the projector turns red.
If the vent is not cleaned periodically, it can become clogged
with dust, preventing proper ventilation. This can cause
overheating and damage the projector.

Follow these steps to clean the vent:
1. Turn off the projector, let it cool down, and unplug the
power cord.
2. Stand the projector on its back panel with the lens pointing
upward.
3. To clean the vent, EPSON recommends using a small
vacuum cleaner designed for computers and other office
equipment. If you don’t have one, use a dry, lint-free cloth.
If the dirt is difficult to remove, you may need to have the air
intake vent replaced. Use the EPSON PrivateLine
