71 5 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 may show up on your projected image. You also need to periodically clean the air filter and the air intake and exhaust vents. A clogged air filter or air vent can block ventilation needed to cool the projector and cause 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 servicer. This chapter covers the following: ■Cleaning the lens ■Cleaning the projector case ■Cleaning and replacing the air filter ■Replacing the lamp ■Resetting the lamp timer ■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 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.
72Maintaining and 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 lens cleaner and gently wipe the lens surface. Cleaning the Projector Case Before you clean the case, first 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 mild detergent. Then wipe the case. ■Do not use wax, alcohol, benzene, paint thinner, or other chemical detergents. These can damage the case. caution Do not use glass cleaner to clean the lens.
Maintaining and Transporting the Projector73 Cleaning and Replacing the Air Filter Clean the air filter and air intake and exhaust vent on the bottom of the projector after every 100 hours of use. If they are not cleaned periodically, they can become clogged with dust, preventing proper ventilation. This can cause overheating and damage the projector. When the filter and vent are clogged, the projector displays the message The projector is overheated. To clean the air filter and air vent, follow these steps: 1. Turn off the projector, allow it to cool down, and unplug the power cord. 2. Turn the projector upside-down and clean the filter and air intake vent on the base of the projector. To clean the filter and air 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 brush). If the dirt is difficult to remove or if the filter is torn, replace it. Contact your dealer or call Epson at (800) 873-7766 to obtain a new one. The air filter set (part number V13H134A08) contains two filters. In Canada, please call (800) 463-7766 to locate a dealer.
