If a projector experiences a problem, it can send an e-mail 
message to each of the addresses you provided using EMP 
NetworkManager. The message includes the heading 
“EPSON Projector” in the subject line. The body of the 
message contains the name of the projector, the projector’s IP 
address, and a description of the problem. The problem 
descriptions are similar to the errors reported by EMP 
Monitor listed on page 20. 

If a plus (+) sign appears before the description, it indicates 
that a problem has occurred. A minus (–) sign appears when 
the problem goes away or is resolved.

The lights on top of the projector indicate the projector’s 
status and let you know when a problem occurs. 

Clean the lens whenever you notice dirt or dust on the surface. 
❏ Use a canister of compressed air to remove dust. 
❏ To remove dirt or smears on the lens, use lens-cleaning 

paper. If necessary, moisten a soft cloth with lens cleaner 
and gently wipe the lens surface.

All lights are off.

Make sure the power cord is connected 
securely both at the power outlet and the 
projector. If you’ve just replaced the lamp, 
make sure the cover is on (see page 22)

Rapid cooling in progress. Although this is 
not an abnormal condition, projection 
stops automatically if the temperature rises 
higher. Make sure there is plenty of space 
around and under the projector, and that 
the air filters and vents are clear.

minutes for the projector to cool, then 
unplug the power cord. Make sure room 
temperature is not above 95 °F (35 °C) and 
there is plenty of space around and under 
the projector. Then plug the power cord 
back in and press the P

isn’t clogged. Clean or replace it as

If the projector still overheats after you 
clean the air filter, the problem may be 
caused by damage to the cooling fan or 
temperature sensor.

Warning: Except for replacing the lamp or 
cleaning and replacing the air filters, do not 
attempt to service the projector yourself.
