Unpacking the Projector After unpacking the projector, make sure you have all these parts: PDF manual and registration CD-ROM Password Protected sticker Projector Remote control Power cord VGA computer cable 2 AA batteries (for remote control) Save all packaging in case you need to ship the projector. Always use the original packaging (or the equivalent) when you need to send the projector to another location. See page 65 for transportation instructions.
Additional Components Depending on how you plan to use the projector, you may need additional components: ■ To receive a video signal from a computer with a USB port, you’ll need a USB cable. One may be provided with your computer, or you can purchase one from Epson. See “Optional Accessories” on page 11. ■ To receive a component video signal from a DVD player or other video device, you’ll need a component-to-VGA video cable.
Image size increases with distance, but can vary depending on the aspect ratio (image shape), how you zoom into the image, and whether you’ve adjusted other image settings. Use the illustrations and tables below to help you determine the projection distance.

6 Solving Problems T his chapter helps you solve problems with your projector and tells you how to contact technical support for problems you can’t solve yourself.
Using On-Screen Help If the image doesn’t look right or your audio isn’t working, you can get help by pressing the ? Help button on the projector or the remote control. 1. Press the ? Help button on the remote control or on the projector. You see the Help menu: 2. Use the arrow buttons on the remote control or the projector to highlight menu items. 3. Press the Enter button on the remote control or the projector to select the menu item and read the solutions. 4.
Checking Projector Status If your projector isn’t working correctly, first turn it off and unplug it. Then plug the power cord back in and turn on the projector. If this doesn’t solve the problem, check the lights on top of the projector. What To Do When the Lights Flash The lights on top of the projector indicate the projector’s status.
Error light(s) status Error light(s) status Description P Green or orange It’s time to replace the lamp. See page 60 for instructions. If you continue to use the lamp after the replacement warning, there is an increased possibility that the lamp may break. Flashing orange Off P Red Off Flashing orange P Red Off Red Rapid cooling is in progress. Although this is not an abnormal condition, projection will stop automatically if the temperature rises higher.
Solving Projector Operation Problems The power doesn’t turn on. ■ If the projector doesn’t turn on when you press the Ppower button, make sure the power cord is connected to the projector and plugged into a working electrical outlet. ■ The power cord may be defective. Disconnect the cord from the outlet and contact Epson as described on page 78. ■ If you’re using the Direct Power On function and you immediately plug the power cord back in after unplugging it, the power may not turn back on.
■ The attached computer may be in sleep mode or displaying a black screen saver. Try pressing a key on the computer. ■ If you are projecting from a DVD player or other video source, make sure you turn it on and press its Play button. ■ If you are projecting from a composite or S-Video video source, make sure the Video Signal setting is correct (see page 47). ■ You can also try resetting all of the menu settings (see page 45).
If you’re using Mac OS X: 1. Open System Preferences. 2. Click Displays. 3. Click Detect Displays. 4. Make sure the VGA Display or Color LCD dialog box is selected. 5. Click the Arrangement or Arrange tab. 6. Make sure the Mirror Displays checkbox is selected. The message Not Supported is displayed. ■ Make sure the correct input signal is selected in the Signal menu (see page 47). ■ Make sure your computer’s resolution and frequency or refresh rate is supported by the projector (see page 84).
■ If you’re projecting an image from a computer with dual display activated, turn dual display off. The image isn’t square, but keystone-shaped. If the image isn’t evenly rectangular, adjust its shape as described on page 33. The image contains static or noise. ■ If you’re using a computer cable longer than 6 feet (1.8 meters), or an extension cable, the image quality may be reduced. ■ Keep your computer and video cables away from the power cord as much as possible to prevent interference.
■ If the projector is angled sharply toward the screen, it may not be possible to focus the entire image. Move the projector to position it more directly in front of the screen. ■ Lower the projection angle to reduce the amount of keystone correction required. ■ Make sure the projector is within the proper range (projection distance) from the screen (see page 15). ■ Make sure the lens is not fogged by condensation.
3. Adjust the Sync setting to increase the image sharpness. The image is too light or dark, or colors are incorrect. note Because of the different technologies used, your projected image may not exactly match the colors on your notebook or computer monitor. ■ Select a different Color Mode option in the Image menu. See page 35 for details on the available options. ■ If you’re displaying video, adjust the Color Adjustment and Color Mode settings on the Image menu.
the volume control in your Windows system tray (lower right corner of the screen). On a Mac, you may be able to adjust the volume from your menu bar (top right corner of the screen) or via the volume control function keys. ■ If you’re using a DVD player or other video source, make sure the cables are connected correctly, as described on page 26.

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. Some images are automatically resized using Epson’s SizeWize™ technology to display in the projector’s native format.

Technical Specifications
B Notices This appendix includes safety instructions and other important information about your projector. Important Safety Instructions Follow these safety instructions when setting up and using the projector: ■ Do not look into the lens when the projector is on. The bright light can damage your eyes. ■ Do not place the projector on an unstable cart, stand, or table. ■ Do not operate the projector on its side, or while tilted to one side.
Notices ■ Never push objects of any kind through the cabinet slots. ■ Do not use or store the projector or remote control in a hot location, such as near a heater, in direct sunlight, or in a closed vehicle. ■ Do not block the slots and openings in the projector case. They provide ventilation and prevent the projector from overheating. Do not operate the projector on a sofa, rug, or other soft surface, or set it on top of loose papers, which could block vents underneath your projector.
■ Use the type of power source indicated on the projector. Use of a different power source may result in fire or electric shock. If you are not sure of the power available, consult your dealer or power company. ■ If you use the projector in a country other than where you purchased it, use the correct power cord for that country. ■ Do not overload wall outlets, extension cords, or power strips. Do not insert the plug into a dusty outlet. This can cause fire or electric shock.
