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.
* The image is resized using Epson’s SizeWise Technology.
Positioning the Projector
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.
Follow these guideline when deciding where to place the
projector:
❏ Place the projector on a sturdy, level surface.
Wide Throw Zoom Lens (V12H004W03)
❏ 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.
To determine the diagonal size of an image (in inches) when
you know the projection distance:
❏ Make sure the projector is within 10 feet of a grounded
electrical outlet or extension cord.
❏ Maximum diagonal size =
(((2.54 × projection distance) / 100) × 36) + 2.13
Image size increases with distance, but varies depending on
how you’ve adjusted the optical zoom and other settings.
❏ Minimum diagonal size =
(((2.54 × projection distance) / 100) × 26.84) + 1.29
To determine the projection distance (in inches) when you
know the diagonal size of the screen image:
TBD
❏ Maximum projection distance =
(((diagonal size – 1.29) / 26.84) × 100 / 2.54
❏ Minimum projection distance =
(((diagonal size – 2.13) / 36) × 100 / 2.54
27 to 36.5 ft
5.3 to 7.2ft
2.5 to 3.5 ft
Middle Throw Zoom Lens (V12H004M03)
approx. distance
from screen
To determine the diagonal size of an image (in inches) when
you know the 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.
❏ Maximum diagonal size =
(((2.54 × projection distance ) / 100) × 27.42) + 1.49
Minimum diagonal size =
(((2.54 × projection distance) / 100) × 20.48) + 1.1
To determine the projection distance (in inches) when you
know the diagonal size of the screen image:
Screen
❏ Maximum projection distance =
(((diagonal size – 1.1) / 20.48) × 100 / 2.54
Projector
❏ Minimum projection distance =
(((diagonal size – 1.49) / 27.42) × 100 / 2.54
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.

Epson PowerLite 7900p Projector - 3
Epson PowerLite 7900p Projector
Long Throw Zoom Lens (V12H004L05)
The projector should automatically detect the correct source.
To determine the diagonal size of an image (in inches) when
you know the projection distance:
Note: If it fails to detect the source, make sure the Computer
Input and BNC Input options in the Setting menu are set to
Auto. See the User’s Guide for more information.
❏ Maximum diagonal size =
(((2.54 × projection distance) / 100) × 20.4) + 1.93
If necessary, you can switch to the correct source by pressing
the corresponding source button on the remote control or
projector. See page 5 for details.
❏ Minimum diagonal size =
(((2.54 × projection distance) / 100) × 15.23) + 1.45
To determine the projection distance (in inches) when you
know the diagonal size of the screen image:
Playing Sound Through the Projector
You can play sound through the projector’s speaker system or
you can attach an external speaker system.
❏ Maximum projection distance =
(((diagonal size – 1.45) / 15.23) × 100 / 2.54
You can use either of these commercially available audio
cables:
❏ Minimum projection distance =
(((diagonal size – 1.93) / 20.54) × 100 / 2.54
❏ If your computer or video equipment is connected to the
Computer or DVI port, use a stereo mini-jack cable.
❏ If your equipment is connected to the Video or S-Video
port, or to the BNC ports, use an RCA-style audio cable.
Connecting the Projector
You can connect the projector to three computer sources or
four video sources—up to a total of four sources altogether.
You can include an independent sound channel for each
source. (See the Quick Setup poster or the User’s Guide for
complete setup instructions.)
Using the Remote Control as a Wireless
Mouse
If you’ve connected a computer to the projector, you can
use the projector’s remote control as a wireless mouse by
connecting a USB cable to both the projector and your
computer. The wireless mouse function is supported on
systems with a USB port running Windows XP, 98, 2000, or
Me; or Macintosh OS 8.6 to OS X 10.2. See the User’s Guide
for details.
Note: The preview feature lets you see all the sources at a glance,
so you can easily switch among them. See page 5.

Readjustment 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.
To change the color mode, press the Color Mode button on
the remote control until you see the mode you want. The
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.
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.
Projecting Images Without a Screen
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.
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.
You can turn off sleep mode using the Sleep Mode option in 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.)
Making Initial Color Corrections
Press the Wall Shot button on
either the remote control or the
projector’s control panel while
projecting an image.
Follow these steps to turn off the projector:
1. Turn off any equipment plugged into the projector.
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.
2. To turn off the projector, press the red P Power button on
the projector or remote control.
Wall Shot ON
You see a confirmation
message. (If you don’t want
to turn it off, press any
other button.)
Note: If the status message indicates
that Wall Shot is off, press the Wall Shot button again to turn
it on.

Controlling Multiple Projectors
Using Password Protection
If you’re using more than one projector, you can control all
the projectors—or just selected ones—by using the projector
ID system with just one remote control. To operate a
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.
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.
Setting the Projector ID
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.
The projector’s default ID is 1. If you need to change it,
follow these steps:
1. Access the projector’s Advanced2 menu, highlight
Projector ID and press Enter.

Understanding the Notification Messages
4. Verify that the network settings are correct. (If DHCP is
on, you don’t need to verify network settings.)
If a projector experiences a problem, it sends an e-mail
message to each of the addresses you provided using EMP
NetworkManager. The message includes the heading “Epson
Projector” in the subject line. The body of the message
contains the name of the projector, the projector’s IP address,
and a description of the problem. The problem descriptions
are similar to the errors reported by EMP Monitor listed on
page 17.
❏ Make any desired changes to the projector’s network
address configuration (turning off DHCP enables the
manual settings).
❏ You can give the projector a name up to 15 characters
long. Do not include the following symbols: ! @ # $ %
^ & ' . _ { } ~.
Naming the projector helps you identify it in EMP
Monitor and EMP NetworkManager, especially if you’re
managing a lot of projectors.
If a plus (+) sign appears before the description, it indicates
that a problem has occurred. A minus (–) sign appears when
the problem goes away or is resolved.

Cleaning the Air Filters and Vents
Replacing the Lamp and Air Filters
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.
The life span of the projection lamp is about 2000 hours. It is
time to replace the lamp when:
❏ The projected image gets darker or starts to deteriorate.
❏ The message LAMP REPLACE appears on the screen when
the lamp comes on (after about 1900 hours) and the
lamp warning light is flashing orange. To maintain
projector brightness and image quality, replace the lamp as
soon as possible.
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).
❏ The
lamp warning light is flashing red (the lamp is
burnt out).
Contact your dealer or call Epson at (800) 873-7766 in the
United States for a replacement lamp. Request part number
V13H010L22. In Canada, please call (800) 463-7766 for
dealer referral.
Note: When you get a replacement lamp for your projector, new
air filters are included. You should replace the filters when you
replace the lamp. You can check how long the lamp has been in
use (see page 22).
Warning: Let the lamp cool fully before replacing it. In the
unlikely event that the lamp has broken, small glass fragments
may be present and should be removed carefully to avoid injury.
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.
9. Gently insert the new lamp.
10. Once the lamp is fully inserted, tighten its screws and
replace the cover. (The projector won’t come on if the lamp
cover is loose.)
❏ 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.)
11. Reset the lamp timer as described in the next section.
