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 7 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.
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.
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.
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).
If you have to raise the projector by adjusting its feet (described on page 7), 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.)

Displaying an 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.

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 8.
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.
4 ft.8 ft.40 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.

Never look into the lens when the lamp is on. This can damage your eyes, and is especially dangerous for children.
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.)
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
button. (If a

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 9. Shutting down the projector correctly prevents premature lamp failure and possible damage to the projector from overheating.

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.

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:
Replace batteries as soon as they run out.
Do not mix old and new batteries.
If the batteries leak, wipe away battery fluid with a soft
cloth. If fluid gets on your hands, wash them immediately.
Remove batteries if you will not be using the remote for a
long period of time.

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.

Using the Remote Control as a Wireless Mouse

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.
To use the remote control as a mouse, you must first connect a mouse cable between your computer and the projector.
Note:
When you connect the mouse cable, your computer mouse is disabled and you can’t use another external mouse with your desktop computer. However, you may still be able to use the built­in mouse pointer on a laptop.
Follow these instructions to use your remote control as a wireless mouse:

Cleaning the Lens

Clean the lens whenever you notice dirt or dust on the surface.
To remove dust, use a canister of compressed air to spray the
lens surface, or lightly wipe the lens surface with a soft, dry, lint-free cloth.
To remove dirt or smears, use lens-cleaning paper. If
necessary, moisten a soft cloth with an alcohol-based cleaner and gently wipe the lens surface.
Caution:
Be careful not to get alcohol-based cleaner on the projector case.

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 outside with a soft, dry,
lint-free cloth.
To remove stubborn dirt or stains, clean the case using a soft
cloth moistened with water and a neutral detergent. Dry it using a separate cloth.
Do not use alcohol, benzene, thinner, wax, or other
.
chemicals. These can damage the case.

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.

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. 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, you may need to have the air intake vent replaced. Use the EPSON PrivateLine
