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.

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.
3. Connect the other end to a grounded electrical outlet.
The Power light on the projector turns orange, indicating
that the projector is receiving power and is in sleep mode,
but is not yet turned on.

Drag one monitor
icon on top of
the other

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.

3. Drag one monitor icon on top of the other.
If this option isn’t available, you may need to select one of
the Simulscan resolution settings. Click the Monitor icon,
then select a Simulscan resolution as shown. (Allow a few
seconds for the projector to sync up after making the
selection.)

What To Do If You See a Blank Screen
If you see a blank screen or a blue screen with the message No
Signal after turning on your computer or video source, do one
of the following:
❏ Make sure the cables are connected correctly, as described in
Chapter 1 of the User’s Guide.

Shutting Down the Projector
When you’ve finished using the projector, follow the
recommended procedure to shut it down. This extends the life
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.
1. If you’ve connected a computer or laptop and it’s displaying
only through the projector, shut down the computer first;
otherwise you won’t be able to see your computer’s display if
you try turning it off after the projector.
Power button on top of the projector or on
2. Press the red
the remote control. You see a confirmation message. (If you
don’t want to turn it off, press any other button.)

3. Press the Power button again. The Power light flashes
orange for a couple of minutes as the projector cools down.
When the projector has cooled, the orange
Power light
stays on and the fan shuts off.
If you want to turn the projector on again, wait until the
Power light stops flashing. Then press the
orange
Power button.
Caution:
To avoid damaging the projector or lamp, never unplug the power
cord when the Power light is green or flashing orange.
4. Replace the lens cap, retract the projector feet, and unplug
the power cord. Also turn off the remote control, if you were
using it.
5. If you’re using a VCR or other video source, turn it off after
you turn off the projector.

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.

6. Disconnect all equipment, and store the projector in a
protective case.

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 Menus

Cleaning the Lens

These on-screen menus let you adjust and customize the
projector features from the remote control:

Clean the lens whenever you notice dirt or dust on the surface.

❏ Video controls the look and quality of the projected image
(from a computer or video source).
❏ Audio adjusts the sound volume and tone.

❏ 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.

❏ Effect customizes the highlighting tools available on the
remote control.

❏ 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.

❏ Setting adjusts features such as the keystone setting, blank
screen color, message prompt, and sleep mode.

Caution:
Be careful not to get alcohol-based cleaner on the projector case.

❏ Advanced controls settings such as menu language, color
intensity, and rear or ceiling projection.
❏ About provides information about the current projector and
lamp settings, and lets you reset the lamp timer when you’ve
replaced the projector’s lamp.

menus are displayed on the left, and the options available for
the current menu are shown on the right.

Before you clean the projector case, turn off the projector and
unplug the power cord.

2. Press the top or bottom of the Enter button to scroll up or
down through the menus and view the available options.
3. Press the center of the Enter button to select a menu. The
highlight moves to the first menu option for that menu.
4. Press the bottom or the top of the Enter button to scroll
through the options. Press the right or left side of the Enter
button to change the setting.
If you want to go back to the default settings on any menu,
select Reset, press Enter, select Yes, and then press Enter.

❏ 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

5. Press the Esc button to save your changes and go back to the
main menu.

Clean the air intake vent after every 100 hours of use, or if the

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.

Let the lamp cool before replacing it. To avoid premature lamp
failure, do not touch the glass portion of the lamp assembly.
3. Turn the projector upsidedown to access the lamp
compartment.
4. To remove the lamp cover,
press on the two tabs and pull
out the cover.

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® Support
Service to obtain the name of the EPSON Customer Care
Center nearest to you. Call (800) 637-7661 and enter the PIN
on the card in your Owner’s Kit. If you can’t find your card,
dial (562) 276-4394 (U.S.) or (905) 709-3839 (Canada). Toll
or long distances charges may apply.

the two lamp cover screws;
you can’t remove the
screws. Then pull out the
lamp by the two notches.
6. Position the new lamp
correctly, then gently insert
it into the projector. Press it
into place and tighten the
retaining screws.

Replacing the Lamp
The projection lamp typically lasts for about 1500 hours of
use. It is time to replace the lamp when:
❏ The projected image gets darker or starts to deteriorate.
Error light on top of the projector is flashing red in
❏ The
1-second intervals.

❏ The LAMP REPLACE message appears on the screen when
the projector lamp comes on (after about 1500 hours of use).
To maintain projector brightness and image quality, replace
the lamp as soon as possible after you see the message.

7. Insert the lamp cover as shown and press it back into place.

Note:
To view the number of hours your lamp has been used, check the
About menu.

2. Allow the projector to continue cooling for at least one hour
(if it has been on).

8. Follow the instructions on page 11 to access the projector’s
About menu and reset the lamp counter to zero.
