Positioning the Projector
The location in which you choose to set up your projector
depends on the size of the room and your presentation style.
❏ Place the projector on a sturdy, level surface, within this
distance from the screen:
3.3 to 36 feet in Wide mode
3.9 to 43.2 feet in Tele mode
(see page 6 for more information on these modes)
❏ 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 your
computer and/or video source.
If you have to raise the projector by adjusting its feet
(described on page 6), you’ll need to square-up the sides of
image by pressing the Keystone button (also on page 7).
If you’ll be projecting from overhead, you’ll get the bestlooking picture by mounting the projector upside-down,
parallel to the ceiling, with the bottom of its lens level with the
top of the screen. (You’ll also need to select ceiling projection
mode in the projector’s Advanced menu.)
❏ Place the projector directly in front of the center of the
screen, facing it toward the screen squarely. Otherwise, your
image will not be square.
Displaying an Image
Note:
It’s best to position the screen directly in front of the room. If it’s
placed diagonally in a corner, it’s much more difficult to aim the
projector at the screen correctly and get a square image.
Once you’ve connected the projector to your computer or
other equipment, you’re ready to turn on the projector, adjust
the image, and give your presentation.
Most presenters find it convenient to place the screen in the
front of the room with the projector back near the front of the
audience, leaving ample room between the screen and
projector to get a good-sized image. Then the presenter can
stand in front of the room, facing the audience and control the
equipment from there.
Use the figure below as a guideline to help you determine how
far from the screen to place the projector. Your image size may
not exactly match these sizes; its actual size depends on
whether you have adjusted the image size setting (using
keystone correction or the Wide/Tele button).
Turning On Your Equipment
Make sure your projector and other equipment are set up and
connected correctly. Then plug in and turn on your
equipment, as described below.
Note:
If you have more than one source connected, you may have to
switch to the one you want to use, as described on page 5.
Follow these steps to plug in and turn on your equipment:
1. If you’re projecting video, first plug in and turn on your
VCR, DVD player, or other video source. (If you’re
projecting from a computer, go to step 2.)
2. To turn on the projector, first connect one end of the power
cord to the projector’s power inlet on its left side.

8 ft.
4 ft.
distance from
the screen
When projecting from a table, the ideal arrangement is to set
the projector flat on its surface with the base of the lens at
about the level of the bottom of the screen. This delivers the
best-looking picture.
3. Connect the other end to a grounded electrical outlet.
The Power light on the projector turns orange, indicating
that the projector is receiving power and is in sleep mode,
but is not yet turned on.

4. Remove the lens cap.
❏ Try restarting your computer.
5. Press the red
Power button on top of the projector. (You
can also turn on the projector using the remote control, but
you must turn on the remote control first.)
❏ If you still don’t see an image and you’re using a PowerBook
or a PC laptop, see the next sections.
If You’re Using a PowerBook . . .
The
Power light flashes green and then stays on. You see
a blue screen with the message No Signal displayed.
You may need to set up your system to display on the
projector screen as well as the LCD screen. Follow these steps:
Warning
Never look into the lens when the lamp is on. This can damage
your eyes, and is especially dangerous for children.
1. From the Apple menu, select Control Panels, then click
Monitors and Sound.
2. Click the Arrange icon.
6. If you’re projecting images from a computer, turn on your
computer. In a few moments, you should see your computer
display projected. (If a projected image fails to appear, see
the next section for help.)
Click here
Note:
Windows only: If you see a New Hardware Found message saying
that Windows has found a plug-and-play monitor, click Cancel.
7. If you’re projecting video, press the Play button. (If a
projected image fails to appear, see the next section for help.)
Drag one monitor
icon on top of
the other
Once you see your image, turn to page 6 for instructions on
focusing and making other image adjustments.
When you’re done with your presentation, shut down the
projector as described on page 8. Shutting down the projector
correctly prevents premature lamp failure and possible damage
to the projector from overheating.
3. Drag one monitor icon on top of the other.
If this option isn’t available, you may need to select one of
the Simulscan resolution settings. Click the Monitor icon,
then select a Simulscan resolution as shown. (Allow a few
seconds for the projector to sync up after making the
selection.)
What To Do If You See a Blank Screen
If you see a blank screen or a blue screen with the message No
Signal after turning on your computer or video source, do one
of the following:
❏ Make sure the cables are connected correctly, as described in
Chapter 1.
Click here
❏ Make sure the
Power light is green and not flashing and
the lens cap is off.
❏ If you’ve connected more than one input source, you may
need to press the Source button on top of the projector or
the Computer, Video, or S-Video button on the remote
control to select the source you want to use. (Allow a few
seconds for the projector to sync up.)

Shutting Down the Projector
When you’ve finished using the projector, follow the
recommended procedure to shut it down. This extends the life
of the lamp and protects the projector from possible
overheating.
Note:
If sleep mode is enabled and 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. In sleep mode,
the Power light is orange. If you are done using the projector,
unplug the power cord. If you want to start projecting again, press
the Power button on the projector or the remote control.
1. If you’ve connected a computer or laptop and it’s displaying
only through the projector, shut down the computer first;
otherwise you won’t be able to see your computer’s display if
you try turning it off after the projector.
2. Press the red
Power button on top of the projector or on
the remote control. You see a confirmation message. (If you
don’t want to turn it off, press any other button.)
3. Press the Power button again. The Power light flashes
orange for a couple of minutes as the projector cools down.
When the projector has cooled, the orange
Power light
stays on and the fan shuts off.
Caution:
To avoid damaging the projector or lamp, never unplug the power
cord when the Power light is green or flashing orange.
4. Replace the lens cap, retract the projector feet, and unplug
the power cord. Also turn off the remote control, if you were
using it.
5. If you’re using a VCR or other video source, turn it off after
you turn off the projector.
6. Disconnect all equipment, and store the projector in a
protective case.
Using the Remote Control
The remote control lets you access projector features from
anywhere in the room—up to 32 feet away. You must also be
within a 30° horizontal and a 15° vertical angle from the
infrared receiver at the front of the projector. You can use it to
turn the projector on and off, zoom the image, display the
projector menus, and other uses.
If you connected a mouse cable to the projector, you can also
use the remote control as a wireless mouse to run your
presentation.
Note:
You can aim the remote control at your projection screen and
reflect the signal back into the sensor on the front of the projector,
but this shortens the operating distance of the remote control.
Installing the Remote Control Batteries
The remote control operates the projector and lets you access
its setup menus. You can also use it as a wireless mouse.
Follow these steps to install the
batteries:
1. Press the tab to release the
battery cover and lift it up to
remove it.
2. Insert the two AA batteries
included with the projector
as shown.
3. Replace the battery cover.

Caution:
When replacing batteries, take the following precautions:
Using the Remote Control as a Wireless
Mouse
❑
Replace batteries as soon as they run out.
❑
Do not mix old and new batteries.
Using the remote control as a wireless mouse gives you more
flexibility; you don’t need to stay near your computer or the
projector to run your presentation.
❑
If the batteries leak, wipe away battery fluid with a soft
cloth. If fluid gets on your hands, wash them immediately.
To use the remote control as a mouse, you must first connect a
mouse cable between your computer and the projector.
❑
Remove batteries if you will not be using the remote for a
long period of time.
Note:
When you connect the mouse cable, your computer mouse is
disabled and you can’t use another external mouse with your
desktop. However, you may still be able to use the built-in mouse
pointer on a laptop.

Cleaning the Air Intake Vent
Clean the air intake vent after every 100 hours of use, or if the
Error light on top of the projector turns red.
If the vent is not cleaned periodically, it can become clogged
with dust, preventing proper ventilation. This can cause
overheating and damage the projector.
01/01
EPSON Powerlite 50c/70c
Follow these steps to clean the vent:
1. Turn off the projector, let it cool down, and unplug the
power cord.
2. Stand the projector on its back panel with the lens pointing
upward.
3. Turn the projector upsidedown to access the lamp
compartment.
4. To remove the lamp cover,
press on the two tabs and pull
out the cover.
5. Use a screwdriver to loosen
the two lamp cover screws;
you can’t remove the
screws. Then pull out the
lamp by the two notches.
3. To clean the vent, 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, replace the air intake vent.

6. Position the new lamp
correctly, then gently insert
it into the projector. Press it
into place and tighten the
retaining screws.
Replacing the Lamp
The projection lamp typically lasts for about 1500 hours of
use. It is time to replace the lamp when:
❏ The projected image gets darker or starts to deteriorate.
❏ The
Error light on top of the projector is flashing red in
1-second intervals.
7. Insert the lamp cover as shown and press it back into place.
❏ The LAMP REPLACE message appears on the screen when
the projector lamp comes on (after about 1500 hours of use).
To maintain projector brightness and image quality, replace
the lamp as soon as possible after you see the message.

To view the number of hours your lamp has been used, check the
About menu.
Request replacement lamp part number ELPLP13.

1. Turn off the projector, let it cool down, and unplug the
power cord.
2. Allow the projector to continue cooling for at least one hour
(if it has been on).

flashes and the projector lamp won’t turn on if the cover is open.
8. Follow the instructions on page 10 to access the projector’s
About menu and reset the lamp counter to zero.
Warning:
Let the lamp cool before replacing it. To avoid premature lamp
