Compatible Video Formats
The projector supports computer displays ranging from VGA 
through UXGA. EPSON’s patented SizeWise
™ chip 
automatically resizes images as needed to display in the 
projector’s native format. The projector also supports the new 
Digital Visual Interface (DVI) format, as well as NTSC, PAL, 
SECAM, and HDTV international video standards.
To project images output from a computer, the computer’s 
video card must be set at a refresh rate (vertical frequency) 
that’s compatible with the projector; see the following table 
for compatible formats. Note that the frequencies of some 
computers may not allow images to be displayed correctly; 
see your computer’s documentation for details.

Positioning the Projector
The projector can be installed in three ways:
❏front projection
Place the projector on a sturdy, level surface, making sure 
there is plenty of space for ventilation around and under the 
projector.
❏overhead projection
To project from overhead, select 
Ceiling in the projector’s 
Advanced menu. To mount the projector, use the special 
attachments and adapters listed in “Optional Accessories” on 
page 14.
❏rear-screen projection
To project from behind a semi-transparent screen, select 
Rear Proj. in the projector’s Advanced menu.
When equipped with the standard lens, you can place the 
projector anywhere from 21 inches to 48 feet from the screen. 
Image size varies with projection distance, as shown below; for 
more information, see page 5.
Be sure to center the projector in front of the screen (not off to 
one side at an angle), or your image won’t be square.
Adjusting the Height of the Image
You won’t need to tilt the projector upward as long as you 
position it so that its lens is at least as high as the bottom of 
the screen, but no higher than the middle of the screen, as 
shown. This delivers the best-looking picture.Adjust the height of the image using the lens shift knob, as 
shown below. If the knob is recessed, press and release it so 
that it extends; then turn it clockwise or counterclockwise to 
move the image up or down. When you’re finished, press the 
knob back in.
If the image still isn’t high enough, you can raise it further 
using the projector’s feet. Pull up on the blue foot release 
levers to release the feet.
Once the image is positioned where you want it, release the 
levers to lock the feet in position. You can fine-tune the height 
of the projector by turning the feet.
If the image is no longer square after raising it, see the 
following section.
Correcting Keystone Distortion
If the projected image isn’t square or 
has “keystone” shape, press the 
Keystone button on top of the 
projector to correct it. Press on the 
right + or left – side of the 
Keystone 
button until the image looks correct.
After correction, your image will be slightly smaller.
Note: You can also correct the keystone shape using the projector’s 
Setting menu.

Using the Remote Control
The remote control uses a line-of-sight infrared signal. It lets 
you access the projector’s features from anywhere in the 
room—up to 32 feet away. You can point the remote either at 
the front or back of the projector or at the screen.
In addition to the functions described on the next page, you 
can also use the remote control as a wireless mouse in the 
following situations:
❏
❏❏ ❏when using EasyMP.net
The remote control lets you select the image you want to 
view, click through your PowerPoint slides, and draw on the 
screen to highlight your presentation. 
❏
❏❏ ❏when presenting from a computer
If you’re presenting from a laptop instead of using 
EasyMP.net, you can use the remote control’s built-in 
pointer and highlighting features. These let you annotate 
your presentation on-screen. 
You can also use the remote control in place of your 
computer’s mouse. This gives you more flexibility when 
delivering PowerPoint and other slideshow-style 
presentations, since you won’t need to stand next to your 
computer to change slides. To use the remote control in this 
way, you have to connect the projector’s mouse cable 
between your computer and the projector. 
❏
❏❏ ❏when accessing the projector’s help and menu functions
The remote control lets you access and use the projector’s 
help system. It also lets you navigate the menu system to 
fine-tune various projector features. 
Note: If the remote control isn’t working, make sure the on/off 
switch on its side is turned on and fresh batteries are installed. 
The remote control also may not work properly if a strong light 
source or radiant heater is present. See the next page for information on using the remote control 
buttons, shown below:

Using the Control Panel 
The following table summarizes the functions on the control 
panel:  
Cleaning the Lens 
Warning: Before you clean any part of the projector, turn off the 
projector and unplug the power cord. Never open any cover on the 
projector, except the lamp and filter covers. Dangerous electrical 
voltages in the projector can injure you severely. Do not try to 
service this product yourself, except as specifically explained below. 
Refer all other servicing to qualified service personnel.
Clean the lens whenever you notice dirt or dust on the surface.
❏Lightly wipe the lens surface with a soft, dry, lint-free cloth.
❏To remove dirt or smears on the lens, moisten a soft cloth 
with an alcohol-based cleaner and gently wipe the lens 
surface.
Cleaning the Projector Case 
Before you clean the projector case, 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, moisten a soft cloth with 
water and a neutral detergent. Then wipe the case. 
❏Do not use alcohol, benzene, thinner, or other chemical 
detergents. These can cause the case to warp.
Cleaning the Air Filter
Clean the air filter at the bottom of the projector after every 
100 hours of use. If it is not cleaned periodically, it 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 cable.
2. Turn the projector on its side so that the handle is on top 
and you can access the filter easily.
Note: Standing the projector with the handle at the top keeps 
dust from getting inside the projector housing.
