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.

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

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.

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 Accessories at (800) 873-7766
