hard-shell shipping case, then pack it in a firm box with 
cushioning around the case. 
■Attach the lens cover to the lens.
■If an SD card is installed, remove it from the projector.
■Return the projector feet to their stored (highest) positions.
■Turn the vertical lens shift dial so that the lens is in its lowest 
position.

Flashing orange It’s time to replace the lamp. See page 126 for instructions. If you 
continue to use the lamp after the replacement warning, there is an 
increased possibility that the lamp may break.
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 filter and vents are clear.
Red The projector is overheating, which turns the lamp off automatically. 
Wait until the projector switches to standby mode (about 5 minutes). 
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 filter may be clogged. Clean or replace the air filter as described 
on pages 122 to 126.
If you’re using the projector above an altitude of 4,900 feet (1,500 
meters), turn on High Altitude Mode in the Operation menu (see 
page 107).
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 146.
Warning: Except as specifically explained in this User’s Guide, do not 
attempt to service this product yourself.
Flashing red Power is cut off because of an internal problem. Unplug the power cord 
and contact Epson for help, as described on page 146.

projector, disconnect the power cord, and contact Epson as described on 
page 146.
Flashing red The lamp may be burnt out. First make sure the lamp cover is securely 
installed. If that’s not the problem, the air filter may be clogged. Clean or 
replace the air filter as described on pages 122 to 126.
If this does not resolve the problem, let the lamp cool and then remove it. 
If the lamp is cracked, replace it as described on page 126. If the lamp is 
not cracked, reinstall it. If reinstalling doesn’t work, replace the lamp.
If you’re using the projector above an altitude of 4,900 feet (1,500 
meters), turn on High Altitude Mode in the Operation menu (see 
page 107).
If none of these suggestions resolves the problem, contact Epson as 
described on page 146.
