    Refer to the following table to see what the indicators mean and how to remedy problems that they indicate.
    If all indicators are off, check that the power cable is connected correctly and that the power is being supplied normally.
    Sometimes, when the power cable is unplugged, the t indicator remains lit for a short period, but this is not a malfunction.

    (overheating)The lamp turns off automatically and projection stops. Wait for about five minutes. After about five minutes 
    the projector switches to standby mode, so check the following two points.
    •Check that the air filter and air exhaust vent are clear, and that the projector is not positioned against a wall.
    •If the air filter is clogged, clean or replace it. 
    If the error continues after checking the points above, stop using the projector, disconnect the power cable 
    from the electrical outlet, and contact Epson. sp.96
    When using at an altitude of 4900 ft (1500 m) or more, set High Altitude Mode to On. sp.66

    Lamp Error
    Lamp FailureCheck the following two points.
    •Take out the both lamps and check if they are cracked. 
    •Clean the air filter. 
    If it is not cracked: Re-fit the lamp and turn on the power.
    If the error continues: Replace the lamp with a new lamp and turn on the power.
    If the error continues: Stop using the projector, disconnect the power cable from the electrical outlet, and 
    contact Epson. sp.96
    If it is cracked: Replace it with a new lamp, or contact Epson for further advice sp.96. If replacing the lamp 
    yourself, be careful to avoid pieces of broken glass (you cannot continue projecting until the lamp is 
    replaced). 
    When using at an altitude of 4900 ft (1500 m) or more, set High Altitude Mode to On. sp.66
    Set Direction to Pointing Down or Pointing Up when the projective direction is downward or upward.

    High Temp Warning (This is not an abnormality. However, if the temperature rises too high again, projection stops automatically.)
    •Check that the air filter and air exhaust vent are clear, and that the projector is not positioned against a wall.
    •If the air filter is clogged, clean or replace it. 
    Replace Lamp The lamp indicated by flashing indicator, lamp 1 or 2, is due for replacement. Replace it with a new lamp. 
    If you continue to use the lamp after the replacement period has passed, the possibility that the lamp may 
    explode increases. Replace it with a new lamp as soon as possible.
    We recommend replacing both lamps together to maintain consistent hue and brightness of projected 
    images.
    Lamp Warning
    Supply System 
    Warning (Ballast)Check the following two points.
    •Remove the lamp indicated by the flashing indicator, lamp 1 or 2, and check if it is cracked. 
    •Clean the air filter. 
    If it is not cracked: Re-fit the lamp and turn on the power.
    If the error continues: Replace the lamp with a new lamp and turn on the power.
    If the error continues: Stop using the projector, disconnect the power cable from the electrical outlet, and 
    contact Epson. sp.96
    If it is cracked: Replace it with a new lamp, or contact Epson for further advice sp.96. (Only one lamp is 
    working. Replace the burned-out lamp as soon as possible.). 
    If replacing the lamp yourself, be careful to avoid pieces of broken glass.
    When using at an altitude of 4900 ft (1500 m) or more, set High Altitude Mode to On. sp.66

    No Air Filter
    Air Flow Sensor Err.Check that the air filter is securely installed. 
    The projector automatically turns off about one minute after it detects that there is no air filter.
    If the error continues even though an air filter is installed, the air filter sensor may be defective. Stop using 
    the projector, disconnect the power cable from the electrical outlet, and contact Epson. sp.96

    points.
    •Check that the air filter and air exhaust vent are clear, and that the projector is not positioned against a wall.
    •If the air filter is clogged, clean or replace it. 
    If the Low Air Flow continues to be low after cleaning the air filter, replace the air filter with a new one.
