Epson 77C 사용자 설명서

Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter or vent on the bottom of the projector, 
clean them as described below. Dust clogs prevent proper ventilation 
and can cause overheating and damage the projector. 

When the filter and vent are clogged, the projector displays the 
message 

The projector is overheating. Make sure nothing is 

blocking the air vent, and clean or replace the air filter.

To clean the air filter and air intake vent, follow these steps:

1. Turn off the projector, allow it to cool down, and unplug the 

power cord.

2. To clean the filter and vent, Epson recommends using a small 

vacuum cleaner designed for computers and other office 
equipment. If you don’t have one, gently clean them using a very 
soft brush (such as an artist’s paintbrush). 

You can remove the air filter to clean both sides.

If the dirt is difficult to remove or if the filter is torn, replace it. 
Contact your dealer or call Epson at (800) 463-7766 to obtain a 
new one (part number V13H134A13).
