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

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 117 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 123.
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L57.

							114Maintaining the ProjectorFollow these steps to replace the lamp:

the lamp cover off.
4. Loosen the two screws holding the lamp in place (you can’t

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
