Positioning the Projector
Follow these guidelines to get the best results when projecting:
❏Place the projector on a sturdy, level surface, between
3 and 48 feet from the screen.
❏Make sure there is plenty of space for ventilation around and
under the projector.
❏Make sure the projector is within 6 feet of a grounded
electrical outlet or extension cord and within 5 feet of the
computer and/or video source.
❏Face the projector squarely toward the screen. Otherwise,
your image will be distorted.
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 squarely at
the screen and get a non-distorted 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:
Note: If you have to raise the front of the projector, you can use
the projector’s keystone correction to eliminate distortion. See
“Adjusting the Image Shape” on page 7.
If you’ll be projecting from overhead, you’ll get the best-
looking picture by mounting the projector parallel to the
ceiling, with its lens at least as high as the middle of the screen,
but no higher than the top of the screen. Then use the lens
shift knob to position the image on-screen. You’ll also need to
select ceiling projection in the projector’s Advanced menu.
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.
Standard Lens
To determine the diagonal size of an image when you know
the projection distance:
❏Inches:
Maximum diagonal size = (0.6676 × projection distance) + 1.8
Minimum diagonal size = (0.5173

Resizing the Image
If only part of your computer screen is displayed, your
computer may be set for a higher resolution than the
projector’s “native” display: 1024 ×768 pixels (PowerLite
8100i) or 1280 ×1024 (PowerLite 9100i). You can resize the
image to fit the resolution of your projector.
❏Press the Resize button on the remote control or the control
panel. The screen image is automatically compressed.
❏Continue pressing the Resize button to pan around the
screen in the original resolution.

Note: You can also resize your image with the Resize button
when you’re projecting from a VCR or other video source.
Projector Status Lights
The lights on top of the projector indicate the projector’s
operating status.
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. (This distance may be shorter if
the remote control batteries are low.) You must also be within
a ±30° angle from the front or rear receiver. If you have
connected the mouse cable, you can also use the remote
control as a wireless mouse.
The projector may not respond to remote control commands
in these conditions:
❏You are too far away or not within 30°to the left or right of
and 15°above or below the front or rear sensor
❏The R/C (remote control) switch is in the OFF position
❏Batteries are weak
❏Ambient light is too bright
❏A fluorescent light is shining into the infrared receiver
❏A strong light source (such as direct sunlight) shines into the
infrared receiver
❏Other equipment emitting infrared energy is present (such as
a radiant room heater)

Cleaning and Replacing 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
prevents dust from getting inside the projector housing.
3. To clean the filter, EPSON recommends using a small
vacuum cleaner designed for computers and other office
equipment. If you don’t have one, use a dry, lint-free cloth.
If the dirt is difficult to remove or if the filter is torn, replace
it.
Note: When you get a replacement lamp for your projector, a
new air filter is included. You should replace the filter when
you replace the lamp.
4. If you need to replace the filter, pull up on the tab to release
the filter and remove it.
5. Insert the new filter as shown.
Replacing the Lamp
The projection lamp typically lasts for about 2000 hours of
use. It is time to replace the lamp when:
❏The projected image gets darker or starts to deteriorate.
❏The lamp light is flashing red or orange.
❏The message LAMP REPLACE appears on the screen when
the projection lamp comes on (after about 1900 hours). To
maintain the projector brightness and image quality, replace
the lamp as soon as possible.
Warning: Let the lamp cool before replacing it. Also, do not touch
the glass portion of the lamp assembly. Touching the glass portion
of the lamp will result in premature lamp failure.
1. Turn off the projector and unplug the power cable.
2. Allow the projector to cool down for at least an hour (if it
has been on).
3. Use a screwdriver to loosen the two retaining screws on the
lamp cover. When the screws are loose, lift off the lamp
cover. (You cannot remove these screws from the cover.)

EPSON PowerLite 8100i/9100i Projector
12 - EPSON PowerLite 8100i/9100i 3/01
4. Use a screwdriver to loosen the three screws holding the
lamp unit in place. (You cannot remove these screws
completely.) Then lift up the handle and pull out the lamp
unit.
5. Gently insert the new lamp as shown below. Make sure it’s
inserted securely. Tighten the screws on the new lamp.
6. Replace the lamp cover and tighten the screws. (Make sure
the lamp cover is securely fastened. The projector turns itself
off if the lamp cover is open.)
7. Reset the lamp timer as described below.
Resetting the Lamp Timer
After you install a new lamp, you need to reset the timer so the
projector can keep track of how many hours it has been used.
Follow these steps:
1. Press the Help button and hold it down for at least 5
seconds. The Help menu will be displayed and then you will
see a menu asking if you want to reset the lamp ON time.
2. Use the left arrow button (control panel) or press left on the
Enter button (remote control) to select Yes.
3. Press Enter to reset the timer.
