    Maintenance
    Cleaning the Parts
    You should clean the projector if it becomes dirty or if the quality of projected images starts to deteriorate.
    Warning
    Do not use sprays that contain flammable gas to remove dirt and dust from the projector's lens, air filter,
    and so on. The projector may catch fire due to the high internal temperature of the lamp.
    Cleaning the air filter
    Clean the air filter if dust has accumulated on the air filter or when the following message is displayed.
    "The projector is overheating. Make sure nothing is blocking the air vent, and clean or replace the air
    filter."
    Attention
    •If dust collects on the air filter, it can cause the internal temperature of the projector to rise, and this can lead
    to problems with operation and shorten the optical engine's service life. It is recommended that you clean
    the air filter at least once every three months. Clean them more often than this if using the projector in a
    particularly dusty environment.
    •Do not rinse the air filter in water. Do not use detergents or solvents.
    •Lightly brush the air filter to clean it. If it is brushed too strongly, dust will be ground into the air filter and
    cannot be removed.
    a
    Press the  button on the remote
    control or the 
     button on the
    control panel to turn off the power,

    Cleaning the lens
    Before cleaning, make sure you unplug the charging adapter from the outlet.
    After manually opening the lens shutter, carefully wipe away any dirt on the lens with a cloth for cleaning
    glasses and so on.
    After cleaning, close the lens shutter.
    Attention
    Do not rub the lens with harsh materials or handle the lens too roughly as it can easily become damaged.
    Cleaning the 3D Glasses
    Use a commercially available cloth for cleaning glasses to gently
    wipe off dirt from the lens.
    Attention
    •Do not rub the lenses of the glasses with harsh materials or
    handle the lenses too roughly as they can easily become
    damaged.
    •When maintenance is necessary, disconnect the USB Charg-
    ing Adapter from the electrical outlet, and check that all ca-
    bles have been disconnected.
    c
    The 3D Glasses contain rechargeable batteries. Observe local regulations when you dispose of them.
    Replacement Periods for Consumables
    Air filter replacement period
    •If the message is displayed even though the air filter has been cleaned s  p.105
    Lamp replacement period
    •The following message is displayed when projection starts: 
    "It is time to replace your lamp. Please contact your Epson projector reseller or visit www.epson.com to purchase."

    •The lamp replacement message is set to appear after 3400 H in order to maintain the initial brightness
    and quality of the projected images. The message display time changes depending on the usage
    situation, such as the color mode setting and so on.
    If you continue to use the lamp after the replacement period has passed, the possibility that the lamp
    may explode increases. When the lamp replacement message appears, replace the lamp with a new
    one as soon as possible, even if it is still working.
    •Depending on the characteristics of the lamp and the way it has been used, the lamp may become
    darker or stop working before the lamp warning message appears. You should always have a spare
    lamp unit ready in case it is needed.

    Warning
    When replacing the lamp because it has stopped illuminating, there is a possibility that the lamp may be
    broken. If replacing the lamp of a projector that has been suspended from the ceiling, you should always
    assume that the lamp is cracked, and remove the lamp cover with care. When you open the lamp cover,
    small shards of glass could fall out. If any shards of glass get into your eyes or mouth, contact a doctor
    immediately.
    Caution
    •Do not touch the lamp cover immediately after turning off the projector as it is still hot. Wait until the lamp
    has cooled down sufficiently before removing the lamp cover. Otherwise, you could get burnt.
