Positioning the Projector
Follow these guideline when deciding where to place the
projector:
❏ Place the projector on a sturdy, level surface.
❏ Make sure there is plenty of space for ventilation around
and under the projector. Do not set it on top of anything
that could block the vents under the projector.
❏ Make sure the projector is within 10 feet of a grounded
electrical outlet or extension cord.
Image size increases with distance, but varies depending on
how you’ve adjusted the optical zoom and other settings.
TBD
Calculating Image Size and Projection Distance
Use the formulas below either to find out how large your
image will be when you know the distance from the projector
to the screen, or to find out how far from the screen to place
the projector if you want an image of a certain size. Since the
size of the image can be changed by rotating the zoom ring,
formulas are given for calculating both the minimum and
maximum sizes.
Note: The formulas given here are for when the projector is placed
flat, without tilting it up at the screen. If you tilt it up by
extending the feet or use electronic keystone correction, your image
size may vary.
Wide Throw Zoom Lens (V12H004W03)
To determine the diagonal size of an image (in inches) when
you know the projection distance:
❏ Maximum diagonal size =
(((2.54
×
projection distance) / 100)
❏ Minimum diagonal size =

×
projection distance) / 100)
To determine the projection distance (in inches) when you
know the diagonal size of the screen image:
❏ Maximum projection distance =

It’s best to place the projector directly in front of the center of
the screen, facing the screen squarely. If it isn’t placed this
way, the image will be “keystone” shaped, instead of
rectangular.
Screen
Projector
Overhead View
If you place the projector below screen level, you’ll have to tilt
it up by extending the front adjustable foot. This also causes
the image to lose its rectangular shape. To correct distortion,
see “Adjusting the Image Shape” on page 7.

currently selected setting appears in the upper right corner of
the screen. You can also use the projector menu system to select
the Color Mode in the Video menu.
Projecting Images Without a Screen
Even if you don’t have a screen, you can project images onto
surfaces like blackboards and colored walls without loss of
image color. Your projector has a sensor that measures the
conditions of the projection surface and automatically adjusts
the colors and shading of your image.
Making Initial Color Corrections
Press the Wall Shot button on
either the remote control or the
projector’s control panel while
projecting an image.
Wall Shot’s status appears in the
upper right corner of your screen.
Then you see a sequence of colors
flash for approximately five
seconds while the sensor measures
the conditions of the projection
surface and adjusts the image.
Note: If the status message indicates
that Wall Shot is off, press the
Wall Shot button again to turn
it on.
Wall Shot ON
When you turn off the projector, it stores the correction values
obtained by the last Wall Shot measurements. This is useful if
you’re projecting against the same surface and under the same
conditions. To retrieve these corrections, just press the
Shot
button again while projecting an image.
Wall
Adjusting Color Corrections for a New Surface
Follow these steps to adjust the correction values if you’re
projecting on a new surface or in a new location:
1. Press the
Wall Shot button on the remote control or
projector while you’re projecting an image. Wait for the
Wall Shot status screen.
2. Press the
Readjustment
Wall Shot button until you see Wall Shot
on the status screen.
You see a sequence of colors flash for about five seconds as
the projector adjusts the color correction values for the new
projection surface.
Shutting Down the Projector
When you’ve finished using the projector, follow the
recommended procedure below to shut it down. This extends
the life of the lamp and protects the projector from possible
overheating.
Note: When 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. If you are done using the projector,
unplug the power cord. If you want to start projecting again, press
the P
Power button.
You can turn off sleep mode using the
Setting menu. If
Standby Mode has been set to Network ON
(in the Advanced1 menu), the lamp turns off but the projector
does not go into full sleep mode. (It provides enough operation to
allow network access.)
Follow these steps to turn off the projector:
1. Turn off any equipment plugged into the projector.
2. To turn off the projector, press the red P

After the projector has cooled, the orange light stays on and
the exhaust fan shuts off.
Caution: To avoid damaging the projector or lamp, never
unplug the power cord when the P power light is green or
flashing orange.
If you want to turn the projector on again, wait until the
orange light stops flashing. Then press the P

battery power.
7. Disconnect any equipment plugged into the projector.
Using the Remote Control
The remote control lets
you access your
projector’s features from
anywhere in the room
(up to 30 feet away).
If the projector does not respond to the remote control, make
sure batteries are installed and the switch on its side is turne d

projector, you have to set the remote control’s ID to match
that of the projector. Or you can control all of the projectors
simultaneously by setting the remote control’s ID to zero.

Using Password Protection
If you assign a password to 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 th e password before you ca n use
the projector.
Follow the instructions below to set the password, and then
turn on the password and/or user logo protection.

Managing Projectors from a Remote Computer
The projector’s software lets you monitor and control
projector(s) from a remote computer. These features are
intended for use by network administrators.
❏ Use EMP Monitor to see your projectors’ status, switch
image sources, and control basic settings.
❏ Use EMP NetworkManager to receive e-mail notifications
alerting you to possible problems.
❏ Use a network management utility running SNMP, such as
HP OpenView,
a pre-existing system.
Note: A plug-in is available to allow you to manage your
projectors in HP OpenView. Additionally, other SNMP
management utilities may be available in the future. Check with
Epson for availability.
Make sure you have installed the software (included on the
projector’s CD-ROM) on the computer you want to use to
monitor your projectors. (See the User’s Guide for

paper. If necessary, moisten a soft cloth with lens cleaner
and gently wipe the lens surface.
Caution: Do not use glass cleaner to clean the lens.

Cleaning the Air Filters and Vents
Clean the air filters and air intake vents after every 100 hours
of use. If they are not cleaned periodically, they can become
clogged with dust, preventing proper ventilation. This can
cause overheating and damage the projector.
Follow these steps:
1. Turn off the projector and unplug the power cord.
2. To clean the intake vents, Epson recommends using a small
vacuum cleaner designed for computers and other office
equipment. If you don’t have one, gently clean the vents
with a soft brush (such as an artist’s paintbrush).
3. Gently turn the projector over and remove the filters from
the side and bottom of the projector. Then use a small
vacuum cleaner or soft brush to clean the two filters. Slide
the filters back into place when you’re done.

Transporting the Projector
The projector contains many glass and precision parts. Follow
these guidelines to prevent injury or damage when
transporting it:
❏ When hand-carrying the projector, you should use the
handle to carry it only a short distance (for example, to set
it on a table).
❏ When shipping the projector for repairs, use the original
packaging material if possible. If you do not have the
original packaging, use equivalent materials, placing plenty
of cushioning around the projector.
❏ When transporting the projector a long distance, first place
it in a hard-shell shipping case, and then pack it in a firm
box, placing cushioning around the case. (An optional ATA
shipping case is available from Epson; see the following
table.)
