You also need to periodically clean the air filter. 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. ¨ Warning: Before you clean any part of the projector, turn off the projector 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.
n n n n 56 Cleaning the Lens Clean the lens whenever you notice dirt or dust on the surface. Lightly wipe the lens surface with a soft, dry, lint-free cloth. To remove dirt or smears on the lens, moisten a soft cloth with an alcohol-based cleaner and gently wipe the lens surface. Cleaning the Projector Case To clean the projector case, first unplug the power cable. 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, thinners or other chemical detergents. These can cause the case to warp.
Cleaning the Air Filter n n n n n n 57 Cleaning the Air Filter Clean the air filter at the top 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. Stand the projector with the lens at the top. ¨ Note: Standing the projector with the lens at the top keeps dust from getting inside the projector housing. 3. Use a small vacuum cleaner designed for computers and other office equipment to clean the filter. If the dirt is difficult to remove or if the filter is torn, replace it. Contact your dealer or call EPSON Service Center.
n n n n 58 Replacing the Lamp Replace the lamp when: • The projected image gets darker or starts to deteriorate. • The projection lamp indicator is flashing orange . • The message “LAMP REPLACE” appears on the screen when the projector lamp comes on. ¨ Note: To keep the initial brightness and image quality, replace the lamp as soon as possible when the message appears on the screen. The replacement message is set to being displayed at about 2000 hours of use. Contact your local EPSON dealer for a spare lamp. Request part number ELPLP10B (EMP-700/500) or ELPLP10S (EMP-710). ¨ Warning: Let the lamp cool before replacing it. Also, do not touch the glass portion of the lamp assembly.
