EPSON PowerLite 8150i Projector
6 - EPSON PowerLite 8150i Projector 5/01
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.
