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. 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: Before you clean any part of the projector, turn off the 
projector and unplug the power cord. Never open any cover on 
the projector, except the lamp and filter covers. Dangerous 
electrical voltages in the projector can injure you severely. Do not 
try to service this product yourself, except as specifically explained 
in this User’s Guide. Refer all other servicing to qualified service 
personnel.

Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the 
surface. Lightly wipe the lens surface with a soft, dry, lint-free 
cloth.
To remove dirt or smears on the lens, moisten a soft cloth 
with an alcohol-based cleaner 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 case 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 case.
Do not use alcohol, benzene, thinners or other chemical 
detergents. These can cause the case to warp.

Cleaning the Air Filter
Clean the air filter at the top 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. Stand the projector with the lens at the top.
¨
Note: Standing the projector with the lens at the top keeps dust 
from getting inside the projector housing.
3. Use a small vacuum cleaner designed for computers and 
other office equipment to clean the filter.
If the dirt is difficult to remove or if the filter is torn, 
replace it. Contact your dealer or call EPSON Service 
Center.

Replacing the Lamp
Replace the lamp when:
• The projected image gets darker or starts to deteriorate.
• The projection lamp indicator is flashing orange .
• The message “LAMP REPLACE” appears on the screen 
when the projector lamp comes on.
¨
Note: To keep the initial brightness and image quality, replace 
the lamp as soon as possible when the message appears on the 
screen. The replacement message is set to being displayed at about 
2000 hours of use. Contact your local EPSON dealer for a spare 
lamp. Request part number ELPLP14.
¨
Warning: Let the lamp cool before replacing it. Also, do not 
touch the glass portion of the lamp assembly. Touching the glass 
portion of the lamp will result in premature lamp failure.
1. Turn off the power and allow the unit to cool down, then 
remove the power cord.
The amount of time needed to cool down will depend on 
the ambient temperature.

screwdriver, and pull out the lamp using the handle.

correct, and then press it into place securely. Tighten the 
mounting screws for the lamp with the screwdriver.

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.
qThe operation indicator is flashing orange and you 
cannot turn on the projector.
The lamp is cooling down. Wait until the light turns off and 
then turn on the projector.
qThe 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.
qProjected images get darker or start to deteriorate, or 
the lamp indicator is red.
Replace the projector lamp as described on page 58.

qThe 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 on page 
57 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.
¨
Warning: Do not attempt to service this product yourself except 
as specifically explained in this User’s Guide.

Problems with the Image or Sound
qAn 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 Source button 
on the appropriate input operation panel to choose another 
image source. 
qOnly 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. For 
supported display settings, see  “Supported Monitor 
Displays” on page 69, 70.
You also may need to modify existing presentation files if 
you created them for a different resolution. See your 
software manual for specific information.
qThe 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 Video (computer/video) menu.
