4 Maintaining and Transporting the Projector77 Maintaining and Transporting the Projector Your projector needs little maintenance. All you need to do on a regular basis is keep the lens clean. Any dirt or smears on the lens will show up on your projected image. You also need to periodically clean the air filter on 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. This chapter covers the following: Cleaning the lens Cleaning the projector case Cleaning and replacing the air filter Replacing the lamp Transporting the projector Cleaning the Lens Clean the lens whenever you notice dirt or dust on the surface. Use a canister of compressed air to remove dust. To remove dirt or smears on the lens, use lens-cleaning paper. If necessary, moisten a soft cloth with an alcohol-based lens cleaner and gently wipe the lens surface. Avoid touching any part of the projector case with any alcohol cleaner. 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 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.
78Maintaining and Transporting the Projector Cleaning the Projector Case Before you clean the case, 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. Then wipe the case. Do not use alcohol, benzene, thinner, or other chemical detergents. These can cause the case to warp. Cleaning and Replacing 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 or replace 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. 3. To clean the filter, EPSON recommends using a small vacuum cleaner designed for computers and other office equipment. If you don’t have one, gently clean the filter using a very soft brush (such as an artist’s camel-hair brush). note Standing the projector with the handle at the top prevents dust from getting inside the projector housing.
Maintaining and Transporting the Projector79 If the dirt is difficult to remove or if the filter is torn, replace it. See page 92 for information on ordering accessories. 4. If you need to replace the filter, pull up on the tab to release the filter and remove it. 5.

When transporting the projector as freight or checked luggage, first put it in a hard-shell carrying case (such as an optional EPSON accessory case), then pack it in a firm box, using cushioning around the case. When you are hand-carrying the projector, be sure to store it in a carrying case (such as the optional cases offered by EPSON). note EPSON shall not be liable for any damages incurred during transportation.
