Important Safety Information
WARNING: Never look into the projector lens when the lamp is turned on; the bright light can damage your eyes.
Never let children look into the lens when it is on. Never open any cover on the projector, except the lamp and
filter covers. Dangerous electrical voltages inside the projector can severely injure you. Except as specifically
explained in this User’s Guide, do not attempt to service this product yourself. Refer all servicing to qualified service
personnel.
WARNING: The projector and its accessories come packaged in plastic bags. Keep plastic bags away from small
children to avoid any risk of suffocation.
Caution: When you replace the lamp, never touch the new lamp with your bare hands; the invisible residue left by
the oil on your hands may shorten the lamp life. Use a cloth or glove to handle the new lamp.

Setting Up the Projector
This chapter tells you how to unpack the projector and connect it to
a notebook or desktop computer or to video equipment, such as a
VCR, DVD player, or video camera.
You can also connect the projector to a USB storage device or digital
camera (EX51/EX71 only).
Follow the instructions in this chapter on:
■ Unpacking the projector
■ Positioning the projector
■ Connecting to a computer
■ Connecting to video equipment
■ Playing sound through the projector
■ Connecting to a digital camera or other USB device (EX51/EX71
only)
■ Turning the projector on and off
20 Setting Up the Projector
Unpacking the Projector
After unpacking the projector, make sure you have all these parts:
Save all packaging in case you need to ship the projector. Always use
the original packaging (or the equivalent) when you need to send the
projector to another location. See page 87 for transportation
instructions. (If you are moving the projector by hand, use the
carrying case.)

Additional Components
Depending on how you plan to use the projector, you may need
additional components:
■ To receive an HDMI signal from your video device, you’ll need
an HDMI cable (EX51/EX71 only). One may be provided with
your video equipment.
■ To receive a component video signal from a DVD player or other
video device, you’ll need a component-to-VGA video cable. One
may be included with your video equipment, or you can purchase
the ELPKC19 cable from Epson. See “Optional Accessories” on
page 16.
■ To receive an S-Video signal, you’ll need an S-Video cable. One
may be included with your video equipment, or you can purchase
one from Epson. See “Optional Accessories” on page 16.
■ To receive an audio signal, you’ll need an RCA-type audio cable
with two male plugs, or a stereo mini-jack audio adapter cable
(with red and white jacks on one end) for the EX31.
Positioning the Projector
If the projector isn’t already installed in the room you’re using, you’ll
probably want to place it on a table in front of the screen. This lets
you stand in the front of the room, face the audience, and remain
close enough to the equipment to be able to control it.
Keep these considerations in mind as you position the projector:
■ Place the projector on a sturdy, level surface.
■ Make sure there is plenty of space for ventilation around and
under the projector.
■ Make sure the projector is within 5.9 feet (1.8 meters) of a
grounded electrical outlet or extension cord.

Projector Placement Options
When projecting from the front, you should place the projector
directly in front of the center of the screen, facing the screen squarely.
The center of the lens should be about level with the bottom of the
screen.
If you place the projector below screen level, you may need to tilt it up
by extending the front adjustable foot. Tilting the projector causes the
image to become “keystone” shaped, bu/t you can correct the
distortion (see page 47). The EX51/EX71 may be able to correct the
distortion automatically.

connect a Kensington
MicroSaver
®
anti-theft
device to the lock port on the

page 16.
Front projection
Setting Up the Projector 27
You can also install the projector in three other viewing setups: ceiling
projection, rear projection onto a semi-transparent screen, or
rear/ceiling projection.
To project from overhead, you’ll need the optional ceiling mounting
hardware (see page 16). You’ll also need to select the appropriate
Projection setting in the projector’s Extended menu to orient the
image correctly (see page 71).
Connecting to a Computer
You can connect the projector to a Windows computer using the
projector’s
TypeB USB port. This lets you carry a lightweight cable
with you when you transport the projector (see page 28).
You can connect the projector to any computer that has a standard
video output (monitor) port, including desktop models, PC notebook
computers, Macintosh PowerBook
®
and iBook
®
computers, and
hand-held devices. See page 30 for instructions.
To play sound through the projector, connect an audio cable (see
page 37).
You may be able to use your remote control as a wireless mouse when
projecting from a computer (see page 56).

28 Setting Up the Projector
Connecting to the USB Port
You can connect a Windows Vista, XP, or Windows 2000 (SP4)
computer to the projector’s
TypeB (square) USB port and
project your computer’s display. A USB 2.0 connection
(recommended) provides better picture quality and response than
USB 1.1.
The first time you connect a computer to the projector’s USB port,
software from the projector is installed on your computer.
1. Follow the instructions beginning on page 40 to turn on the
projector.
2. Make sure the
USB Type B setting on the Extended menu is set
to
USB Display (see page 70).
3. Turn on your computer.
4. Connect the square end of a USB cable to the projector’s
TypeB
(square) USB port.

5. Connect the flat end of the cable to any available USB port on
your notebook or desktop computer.
Messages appear on your computer screen as the projector is
recognized and the software is installed automatically.
6. Follow the instructions on the screen to install the Epson USB
Display software. If you see a “Digital Signature Warning,” select
Continue or Continue Anyway. (You see these instructions only
the first time you connect.)
After the software is installed, you see your computer’s current
desktop displayed by the projector. You can switch the projector
to other image sources using the
Source Search or Search
button on the remote control or the projector.
7. You can connect an optional audio cable if you want to play
sound through the projector (see page 37).
When you’ve finished making connections, see Chapter 2 for
instructions on displaying and adjusting the image.
When you’re done projecting from your computer, disconnect the
USB cable.
note
If the software does not
install automatically, you
can install it manually.
30 Setting Up the Projector
Connecting to the VGA Computer Port
You can connect to the projector using the VGA computer cable that
came with it (the monitor port on your computer must be a D-sub
15-pin port).
1. Connect one end of the VGA computer cable to the projector’s
Computer (Component Video) port and the other end to your
computer’s monitor port.
2. You may need to change the
Input Signal setting in the
projector’s Signal menu to
RGB or Auto (see page 68).
3. You can connect an optional audio cable to play sound through
the projector (see page 37).
4. You may also be able to use the remote control as a wireless mouse
(see page 56).
caution
Don’t try to force a
connector to fit a port with a
different shape or number of
pins. You may damage the
port or connector, or the
device you are trying to
connect.
