Understanding the Notification Messages
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.
Note: If a projector develops a critical problem, it may not be
possible for it to report the error.

Description and solution
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.
The projector has overheated, which turns
off the lamp automatically. Wait about 5
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
turn the projector on again.
If it still overheats, check that the air filter
isn't clogged. Clean or replace it as
described on page 22.
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.
There is a problem with a fan or
temperature sensor. Unplug the power
cord and contact EPSON for help.
It's time to replace the lamp. See page 22
for instructions.
Warning: If you continue to use the lamp
after the replacement warning, there is an
increased possibility that the lamp may
break.
The lamp has burned out. Replace it as
described on page 22.
If these lights come on after replacing the
lamp, make sure the lamp is fully inserted
and the lamp cover is closed.
The projector has an internal problem.
Unplug the power cord and contact EPSON
for help.
