Images are displayed in true XGA and SVGA full color
(16,670,000 colors) at a resolution of 1024 × 768(EMP­7550/7500) and 800 × 600(EMP-5550/5500) pixels. Your
projector produces bright images that can be easily seen in
rooms light enough to take notes. Audio can be produced
from the projector’s 1W+1W stereo, which employ a built-in
SRS 3D sound® for output that is rich and powerful. You can
also connect an external speaker when further amplification is
required.

A totally new AVTSS™ (Automatic Video Tracking and
Synchronization Sensing, patent pending) provides automatic
set-up of image from a computer for quick and easy
projection of beautiful images every time.

You can control your projector through a hand-held remote
control unit, with menus being provided for image source
switching and image adjustment. The remote control can also

source. To display composite video, first disconnect the
S-Video source.

The projector supports NTSC, PAL, PAL 60 and SECAM
video formats, and automatically detects and identifies the
video format. However, you can specify that a single
broadcast format being detected. (See “Video menu” in
Chapter 3.)
Note that the projector will then be able to detect only one
type of video format.

The type of cable you use to connect the video source to
the projector depends on whether you have composite
video, S-Video or G Sync-Video. For composite video, use
the audio/video (A/V) cable supplied with the projector.
For S-Video, use the S-Video cable and the audio cable
supplied with your video device or obtain one from your
computer dealer. For G Sync-Video, use the BNC type
cable came with your video source.

■

To connect a video source to the projector:

1. Turn off the projector and video source if they are on.

2. If your composite video uses an RCA-type composite

video connector, you will need the A/V cable supplied
with your projector. If your video uses a S-Video, you will
need to provide YOUR OWN S-Video or use the S-Video
cable that came with your video source.

3. For composite video, connect the yellow RCA plug at one

end of the A/V cable to the projector’s Video jack.
Connect the other yellow RCA plug to the video-out jack
on the video source.

Resize Button

The Resize button lets you switch between Resize display and
Window display.

The Resize button cannot be used with XGA(1024 × 768
pixels) for EMP-7550/7500 and SVGA(800 × 600 pixels) for
EMP-5550/5500.

How to switch

With images up to XGA(1024 × 768 pixels) size (for example
a 600 × 480 pixels VGA image), press the Resize button
alternately. The Resize display changes the VGA(600 × 480)
image into the SVGA(800 × 600) image. The Window display
projects the VGA(600 × 480) image as it is. The projected
image gets smaller than SVGA(800 × 600) image.

With images SVGA(800 × 600 pixels) size, the image is
displayed with the maximum size in both Resize and Window
display. Pressing the Resize button does not make any
change.

With images larger than SVGA(800 × 600 pixels) size (for
example a 1024 × 768 pixels XGA image), you can either
select to display a portion of the projected image (Window
display) or the entire projected image (Resize display).

Each time you press the Resize button, the projected image is
displayed in the following order:

1. The XGA image is reduced to the SVGA size.

2. The projected image is displayed with XGA size, and only

the upper of the right image is projected on the screen.

3. The upper of the left image is projected on the screen.

4. The bottom of the right image is projected on the screen.

5. The bottom of the left image is projected on the screen.

6. The center of the image is projected on the screen.
After the step 6, press the Resize button again to return to the

step 1.

Maintenance

Your projector needs little maintenance. You should keep the

lens clean because any dirt or smears appear on the screen.
You also need to periodically clean the air filter at the bottom
of the projector.

A clogged air filter can block ventilation needed to cool the
projector and keep it from overheating.

The only parts you should replace are the lamp and air filter.
If any other part needs replacing, contact your dealer or a
qualified service person.

♦

Warning:

Cleaning the Lens

Clean the lens whenever you notice dirt or dust on the
surface. Wipe the lens surface gently with a soft, dry, lint-free
cloth. To remove dirt or stains on the lens, moisten a soft
cloth with water and a neutral detergent and gently wipe the
lens surface.

Cleaning the Projector Case

To clean the projector case, first unplug the power cable. To
remove dirt or dust, wipe the casing with a soft, dry, lint-free
cloth. To remove stubborn dirt or stains, moisten a soft cloth
with water and a neutral detergent. Then wipe the casing.

Cleaning 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. To
clean the air filter, 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 keeps
dust from getting inside the projector housing.

3. Pull up the filter cover tab to release the filter cover.

Remove the cover.

4. The filter is attached to the inside of the filter cover. It is

recommended that you use a small vacuum cleaner
designed for computers and other office equipment to
clean the filter. 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. Contact your dealer or call EPSON Service
Center.

5. Replace the filter cover when you're done.

Troubleshooting

This chapter describes the problems indicated by the status

lights and provides information how to solve problems with
the projector. It is divided into the following sections:

• "Problems with the Projector" on page 58 and 59 tells you

what to do if any of the projector's warning lights come on.

• "Problems with the Image or Sound" on page 60 and 61

describes what to do if you cannot project an image, if the
screen image is not good, or if there is no sound.

If you have a problem, check the appropriate section and
follow all suggestions that apply to your problem. If none of
the suggestions solve the problem, call your dealer or contact
EPSON Service Centre.

Problems with the Projector

If you have problems with the projector, first turn it off and
unplug it. Then plug the power cord back in and turn on the
projector. If this does not solve the problem, check the
warning lights at the top of the projector. These lights alert
you to problems with projector operation.

See the following pages for information on what to do when
you see these warning lights or encounter other specific
problems with the projector.

❑ The operation indicator is flashing orange and you

cannot turn on the projector.

Operation Indicator

Lamp Indicator

Temperature Indicator

■ ■ ■ ■

The lamp is cooling down. Wait until the light turns off and
then turn on the projector.

❑ The operation indicator does not come on.

Turn off the projector, check that the power cable is
connected securely both at the power outlet and the
projector, and press the Power button again.

❑ Projected images get darker or start to deteriorate,

or the lamp indicator is red.

Replace the projector lamp as described on page 54.

■

❑ The temperature indicator is red.

The projector is overheating, which turns the lamp off
automatically. Let the projector cool for a few minutes,
then turn it back on. Make sure nothing is blocking the
ventilation vents.

The air filter may be clogged. Clean it as described in
Chapter 4 and then let the projector cool for a while.

If the projector continues to overheat after you clean the air
filter, the problem may be caused by damage to the cooling
fan or internal circuits. Contact a qualified service person.

Problems with the Image or Sound

❑ An image does not appear on the screen.

Check that the power light is on and the lens cover is off.
Also make sure the cables are installed correctly, as
described in Chapter 1.

The correct image source may not be selected. Press the
Source button on the remote control or the operation
panel to choose another image source.

❑ Only part of the computer image is displayed.

If the computer’s output resolution setting is higher than
1024 × 768, the projector resizes the image. If the
computer output is not compatible with this resizing,
choose a different display setting on the computer. In
Windows 3.x, use Windows Setup in the Main program
group. For a Macintosh, choose Operation Panels under
the Apple menu and then choose Monitors. In the
Monitors screen, choose Options and make sure Macintosh
Hi-Res Display or another 1024 × 768 display is selected.
For supported display settings, see “Supported Monitor
Displays (EMP-7550/7500)” on page 65 or “Supported
Monitor Displays (EMP-5550/5500)” on page 66.

■ ■ ■ ■

You also may need to modify existing presentation files if
you created them for a different resolution. See your
software manual for specific information.

❑ The message NO SIGNAL is displayed.

An image source not connected to the projector is selected,
the signal is not being output from the computer, or the
signal is not reaching the projector. Make sure the
connectors are securely attached to both the projector and
the image source. Then check that the image source is
selected correctly. When NO SIGNAL is displayed, you
cannot access the source (computer/video) menu.

60

■

❑ A blank screen is displayed.

The computer signal cannot be interpreted by the
projector. Verify the display format (see page 65 or 66).
When you see a blank screen, you cannot access the
projector menus.

❑ The image or parts of the image are blurred or not

in focus.

Adjust the Brightness and Contrast settings on the Video
main menu. If you’re viewing a computer image, also try
adjusting the Tracking and Sync buttons on the projector’s
operation panel.

There may be dirt or smears on the lens. Clean the lens as
described in Chapter 4, “Maintenance.”

❑ The colors of the image are not right.

The color balance may be incorrect. If you’re displaying a
computer image, adjust the red, green, and blue settings in
the Video menu. If you’re displaying video, adjust the
Color and Tint (NTSC only) settings on the Video menu.

❑ There is no sound.

First check that the volume setting is not turned all the way
down and that the A/V cable is securely attached to both
the projector and the audio source.

The wrong source is selected. Press either the Computer or
Video button on the remote control or operation panel to
select the proper source.
