Positioning the Projector
Before connecting the projector, you need to decide where to
place it. The location you choose depends on the size of the
room and what you are projecting.
❏ Place the projector on a sturdy, level surface, between
2.8 and 48.3 feet from the screen.
❏ Make sure there is plenty of space for ventilation around and
under the projector. Leave at least 8 inches between the
projector and a wall.
❏ Make sure the projector is within 6 feet of an 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 the screen squarely. Otherwise, your image
will not be rectangular.
Note:
It’s easier to position the projector when the screen is directly in
front of the room. If the screen is placed diagonally in a corner, it’s
much more difficult to aim the projector correctly at the screen and
get a rectangular image.
Use the figure below as a guideline to help you determine how
far from the screen to place the projector. Image size generally
increases with distance, but may vary depending on how you
position the zoom ring and whether you have adjusted the
image size with other settings.
29.8 to 48.3 feet 5.8 to 9.5 feet 2.8 to 4.7 feet
If you place the projector below the level of the screen, you’ll
have to tilt it up by extending the front adjustable foot, as
shown. Tilting the projector upward causes the image to lose its
rectangular shape, but the Auto Keystone feature corrects the
distortion automatically. If the image does not regain its
rectangular shape, the Auto Keystone feature may have been
disabled. To turn it on, see page 6.
If you place the projector level with the bottom of the screen,
the image will be rectangular and you won’t have to adjust it. If
you place the projector higher than the bottom of the screen,
the image will still be rectangular, but you won’t be able to fill
the whole screen with the image.
Starting Up the Projector
Make sure your projector and other equipment are connected
correctly. Then turn on your projector, as described below.
If you turn on your computer or video equipment before
starting the projector, the projector automatically detects and
displays the image source. If you turn on the projector first or
have multiple pieces of equipment connected, you may have to
select the source manually. See page 5.
1. Remove the lens cap.
To calculate measurements, use the following formulas:
❏ To find the projection distance when you know the screen’s
diagonal dimension:
Wide (inches) = ((Diagonal screen size [inches]
× 2.97334) –
2.3937) / 2.54
Tele (inches) = ((Diagonal screen size [inches]
× 3.61474) –
2.06831) / 2.54
❏ To find how large a screen’s diagonal dimension will be
when you know the projection distance:
Wide (inches) = (Projection distance [inches]
× 0.32827 ×
2.54) + 1.6767
Tele (inches) = (Projection distance [inches]
× 0.203 × 2.54)
+ 1.077
Caution:
Do not use the projector with the lens cap in place. The heat
generated by the lamp can damage the cap.
2. Connect one end of the power cord to the projector’s power
inlet. Then connect the other end to an electrical outlet.

Warning:
Never look into the lens when the lamp is on. This can damage
your eyes, and is especially dangerous for children.

If a projected image fails to appear, see “What To Do If You See
a Blank Screen” in the next column.
When you’re done with your presentation, shut down the
projector as described on page 7. Shutting down the projector

from overheating.

After you select a source, the screen goes dark for a moment
before the image appears. The name of the selected source (such
as

Adjusting the Image Shape
The projector automatically corrects images that are distorted
when the projector is tilted up or down (up to a 15° tilt). The

Using Password Protection
If you assign a password for the projector, a screen appears
requesting the password whenever you turn on the projector. If
you enter the password incorrectly three times in succession, the
projector’s operation is locked. Disconnect the projector and
reconnect it. If you enter the incorrect password 30 times in a
row, the projector is locked and remains locked until an
authorized Epson servicer can unlock it.
You can also create a user’s logo for the projector, to be
displayed as the startup screen and/or AV/Mute screen.
Unauthorized users cannot turn it off or change it. This
discourages theft and provides a way to identify the projector
should it be stolen.
Additionally, to make sure a borrowed projector is returned,
you can temporarily disable the password for a set period of
time. When that time has elapsed, the password function is
reactivated and you must enter the password before you can use
the projector.
Follow the instructions below to first set the password, and then
turn on the password and/or user logo protection.
Note:
If you should happen to enable the password before you set one, and
you see the prompt to enter the password, enter the default password
0000 to proceed.

Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
❏ Use a canister of compressed air to remove dust.
❏ To remove dirt or smears on the lens, use lens-cleaning
paper. If necessary, moisten a soft cloth with lens cleaner and
gently wipe the lens.
Caution:
Do not use glass cleaner to clean the lens.
Cleaning and Replacing the Air Filter
Clean the air filter and air intake and exhaust vents on the
bottom and rear of the projector after every 100 hours of use.
If not cleaned periodically, they can become clogged with dust,
preventing proper ventilation. This can cause overheating and
damage the projector. When the filter is clogged, the projector
displays the message
To clean the air filter and air vents, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug the
power cord.
2. Clean the air vent on the back of the projector.
Use a small vacuum cleaner designed for computers and
other office equipment. If you don’t have one, use a very soft
brush (such as an artist’s brush).
The projector is overheated.
Cleaning the Projector Case
Before you clean the case, first turn off the projector and unplug
the power cord.
❏ To remove dirt or dust, wipe the case with a soft, dry, lint-
free cloth.
❏ To remove stubborn dirt or stains, wipe the case with a soft
cloth moistened with a mild detergent.
Caution:
Do not use wax, alcohol, benzene, paint thinner, or other
chemical detergents. These can damage the case.
3. Turn the projector upside-down and clean the filter and air
intake vents on the base of the projector.
