Maintaining the Projector
Your projector needs little maintenance. All you have to do on a 
regular basis is clean the lens, and check that the air filter and vents are 
clean. A clogged air filter or vent can block ventilation needed to cool 
the projector.
The only parts you should replace are the lamp and air filter. If any 
other part needs replacing, contact your dealer or a qualified servicer.
This chapter covers the following:
■Cleaning the projection window
■Cleaning the projector case
■Cleaning the air filter
■Replacing the air filter
■Replacing the lamp
■Replacing the pen batteries
■Replacing the remote control batteries
■Transporting the projector
warning
Before you clean any part of 
the projector, turn it off and 
unplug the power cord. 
Never open any cover on the 
projector, except the lamp 
cover. 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. 
						

							104Maintaining the Projector
Cleaning the Projection Window
Clean the projection window whenever you notice dirt or dust on the 
surface.
To remove dirt or smears on the window, use a commercially available 
cloth for cleaning glasses.
Cleaning the Projector Case
Before cleaning, turn off the projector and unplug the power cord.
■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 and firmly wring the cloth dry. Then wipe 
the case.
caution
Do not rub the projection 
window with harsh 
materials or subject it to 
shocks, or you may damage 
the window.
Do not use wax, alcohol, 
benzene, paint thinner, or 
other chemical detergents. 
These can damage the case. 
						

							Maintaining the Projector105
Cleaning the Air Filter 
Your projector includes an air filter to ensure the best performance 
and help protect your equipment investment. If dust collects on the 
air filter, clean it as described here. Dust clogs prevent proper 
ventilation and can cause overheating, which can damage the 
projector.
1. Turn off the projector.
2. Remove dust from the air filter using a small vacuum cleaner 
designed for computer or office equipment, or gently clean the 
vent with a soft brush (such as an artist’s paintbrush).
You can remove the air filter to clean both sides.
If the filter is too dirty or broken, replace the filter as described below. 
Replacing the Air Filter
You need to replace the air filter if:
■You cannot remove the dust from it
■The air filter is damaged or torn
■You repeatedly see a projected message telling you to clean or 
replace it
note
To order replacement air 
filters, request part number 
V13H134A34. See page 21 
for ordering information.

4. Press in the new air filter until it clicks into place.
Replacing the Lamp
The life span of the projection lamp is about 2500 hours if Power 
Consumption 
in the Settings menu is Normal (default), and 3500 
hours if this setting is 
ECO. See page 111 to check the lamp usage.
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message Replace the lamp appears on the screen and the 
Lamp light flashes orange. To maintain projector brightness 
and image quality, replace the lamp as soon as possible.
You may also need to replace the lamp if the 
Lamp light flashes 
red. See page 117.
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L57.
note
Turn off this product when 
not in use to prolong the life 
of the projector.  
						

							108Maintaining the ProjectorFollow these steps to replace the lamp:
1. Turn off the projector and unplug the power cord.
2. Let the projector cool for at least an hour (if it has been on). The 
lamp is extremely hot immediately after use. 
3. Loosen the lamp cover screw (you cannot remove it). Then slide 
the lamp cover off.
4. Loosen the two screws holding the lamp in place (you can’t 
remove them).
warning
Let the lamp cool fully 
before replacing it. 
In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury. If the projector has 
been installed on the ceiling, 
you should stand to the side 
of the lamp cover, not 
underneath it.
If the lamp is used after the 
replacement period has 
passed, the possibility that 
the lamp may break 
increases. When a lamp 
replacement message 
appears, replace the lamp 
with a new one as soon as 
possible, even if it is still 
working.
Loosen, but don’t 
remove these screws
