    							Maintaining the Projector61
    Cleaning the Air Filters and Vents
    Clean the air filters and air intake vents 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. 
    Follow these steps:
    1. Turn off the projector. Wait for the 
    Power light to stop flashing, 
    then unplug the power cord.
    2. Turn the projector upside down.
    3. To clean the intake vents, use a small vacuum cleaner designed for 
    computers and other office equipment. If you don’t have one, 
    gently clean the vents with a soft brush (such as an artist’s 
    paintbrush).
    4. If the dirt is difficult to remove or the filter is broken, replace the 
    filter as described on page 64. Contact your dealer or call Epson at 
    800-GO-EPSON (800-873-7766) to obtain a new filter. 
    note
    To order replacement air 
    filters, request part number 
    V13H134A08. See page 11 
    for ordering information.

    							62Maintaining the Projector
    Replacing the Lamp and Air Filter
    The life span of the projection lamp is about 2000 hours if 
    Brightness Control in the Setting menu is set to High (default), and 
    3000 hours if 
    Brightness Control is set to Low. 
    It is time to replace the lamp when: 
    ■The projected image gets darker or starts to deteriorate.
    ■The message Replace the lamp appears on the screen when the 
    lamp comes on and the lamp warning light   flashes orange. To 
    maintain projector brightness and image quality, replace the lamp 
    as soon as possible. 
    ■The lamp warning light   flashes red (the lamp is burnt out).
    Contact your dealer or call Epson at 800-GO-EPSON 
    (800-873-7766). Request part number V13H010L32. 
    Follow these steps to replace the lamp and air filter:
    1. Turn off the projector.
    2. When the 
    Power light stops flashing, unplug the power cord.
    3. Let the projector cool for at least an hour (if it has been on). The 
    lamp is extremely hot immediately after use. 
    note
    When you get a replacement 
    lamp for your projector, you 
    should replace the filters.
    To check how long the lamp 
    has been in use, see page 71.
    warning
    Let the lamp cool fully 
    before replacing it. 
    In the unlikely event that 
    the lamp has broken, small 
    glass fragments may be 
    present and should be 
    removed carefully to avoid 
    injury.

    Transporting the Projector
    The projector contains many glass and precision parts. Follow these 
    guidelines to prevent damage:
    ■When shipping the projector for repairs, use the original 
    packaging material if possible. If you do not have the original 
    packaging, use equivalent materials, placing plenty of cushioning 
    around the projector.
    ■When transporting the projector a long distance, first place it in a 
    hard-shell shipping case, then pack it in a firm box with 
    cushioning around the case. (An optional case is available from 
    Epson; see page 11.)note

    Checking Projector Status
    If your projector isn’t working correctly, first turn it off, wait for it to 
    cool (the 
    Power light stops flashing orange), and unplug it. Then 
    plug the power cord back in and turn on the projector. If this doesn’t 
    solve the problem, check the lights on top of the projector.
    What To Do When the Lights Flash
    The lights on top of the projector indicate the projector’s status.
    Refer to the following table for a complete description of the 
    projector’s status lights:
    Temperature 
    lightLamp light Power light
    Status lights
    Light Status Description
    Orange The projector is in sleep or standby mode. You can unplug it or press the 
    P Power button to turn it on.
    Flashing green The projector is warming up. Wait for the image to appear.
    Green The projector is operating normally.
    Flashing orange The projector is cooling down. You can’t turn it back on (and you should 
    not unplug it) until the light stops flashing and remains orange. 
    Red There is a problem with the projector. Check the other two lights and the 
    information on page 70 to diagnose the problem. 
    Calgary-Quebec Users Guide.book  Page 69  Thursday, January 20, 2005  9:26 AM 
    						
    							70Solving Problems
    Flashing red  There is a problem with the fan or temperature sensor. Stop using the 
    projector, disconnect the power cable, and contact Epson as described 
    on page 78.
    Flashing orange Rapid cooling is in progress. Although this is not an abnormal condition, 
    projection will stop automatically if the temperature rises higher. Make 
    sure there is plenty of space around and under the projector for 
    ventilation, and that the air filters and vents are clear.
    Red The projector is overheating, which turns the lamp off automatically. 
    Wait until the cooling fan stops, then unplug the power cord. Plug the 
    power cord back in and press the 
    P Power button. Make sure the room 
    temperature is not above 95 °F (35 °C), and there is plenty of space 
    around and under the projector for ventilation. 
    The air filters may be clogged. Clean or replace them as described on 
    page 61.
    If the projector continues to overheat after you clean the air filter, the 
    problem may be caused by damage to the cooling fan or temperature 
    sensor. Contact Epson for help as described on page 78.
    Warning: Except as specifically explained in this User’s Guide, do not 
    attempt to service this product yourself.
    Flashing orange It’s time to replace the lamp. See page 62 for instructions. If you continue 
    to use the lamp after the replacement warning, there is an increased 
    possibility that the lamp may break.
    Flashing red The lamp may be burnt out. First make sure the lamp cover is securely 
    installed. If that’s not the problem, let the lamp cool, remove the lamp, 
    and replace it as described on page 62. If this does not resolve the 
    problem, contact Epson as described on page 78.
    Flashing red Power is cut off because of an internal problem. Unplug the power cord 
    and contact Epson for help, as described on page 78.
