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.

not an abnormal condition, projection

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

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

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.
