    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. 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.

    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

    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.

    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. Touching the glass 
    portion of the lamp will result in premature lamp failure.
    1. Turn off the power and allow the unit to cool down, then 
    remove the power cord.
    The amount of time needed to cool down will depend on 
    the ambient temperature.

    normally take about an hour to completely cool down.

    provided with the spare lamp, then remove.
    3. Loosen two mounting screws for the lamp with the same 
    screwdriver, and pull out the lamp using the handle.
    4. Mount new lamp. Check that the lamp orientation is 
    correct, and then press it into place securely. Tighten the 
    mounting screws for the lamp with the screwdriver.
