3. EMP NetworkManager connects to the projector, and you see 
this screen: 
4. Verify that the network settings are correct. (If DHCP is on, you 
don’t need to verify network settings.)
■Make any desired changes to the projector’s network address 
configuration (turning off DHCP enables the manual 
settings). 
■You can give the projector a name—up to 15 characters long, 
including the following symbols: 
! @ # $ % ^ &  . - _ { } ~
Naming the projector helps you identify it in EMP Monitor 
and EMP NetworkManager, especially if you’re managing 
more than a few of them.
5. Click 
Mail Notification Settings.
note
The projector must be 
plugged in (projecting or in 
standby mode) for you to be 
able to connect to it. 
To access a projector in 
standby mode, you must 
select 
Network ON as the 
Standby Mode setting in 
the projector’s menu system 
(see page 75). 
Remember that when 
Standby Mode is set to 
Network ON, the exhaust 
fan continues to operate 
after the projector has cooled 
down. This is normal.

NetworkManager. (It does not have to be open for messages to be 
sent or received.)
note
A no-signal message is 
reported when no image 
signals are being input to a 
projector. If the projector 
will not normally be 
displaying an image, do not 
select “no signal” as a 
condition for which you 
want a message to be sent.

Understanding the Notification Messages
If a projector experiences a problem, it sends 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
■a description of the problem 
The problem descriptions are similar to the errors reported by EMP 
Monitor listed on page 87. 
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.

Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean and periodically clean the air filters at the side and base 
of the projector. A clogged air filter can block ventilation needed to 
cool the projector.
The only parts you should replace are the lamp and air filters. If any 
other part needs replacing, contact your dealer or a qualified servicer.
This chapter covers the following:
■Cleaning the lens
■Cleaning the projector case
■Cleaning the air filters and vents
■Replacing the lamp and air filters
■Transporting the projector
Cleaning the Lens
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 tissue. If 
necessary, moisten a soft cloth with lens cleaner and gently wipe the 
lens.
warning
Before you clean any part of 
the projector, turn it off and 
unplug the power cord. 
Never open any cover on the 
projector, except the lamp 
cover. Dangerous electrical 
voltages in the projector can 
injure you severely. Do not 
try to service this product 
yourself, except as specifically 
explained in this User’s 
Guide. Refer all other 
servicing to qualified service 
personnel.
Remove the cap 
before cleaning

							96Maintaining the Projector
Cleaning the Projector Case
Before you clean the case, turn off the projector and unplug the power 
cord.
■To remove dirt or dust, wipe the case with a soft, dry, lint-free 
cloth.
■To remove stubborn dirt or stains, moisten a soft cloth with water 
and a neutral detergent. Then wipe the case.
Cleaning the Air Filters and Vents
Clean the air filters and air intake vents after every 100 hours of use. If 
they are not cleaned periodically, they can become clogged with dust, 
preventing proper ventilation. This can cause overheating and damage 
the projector. 
Follow these steps:
1. Turn off the projector. Wait for the Power light to stop flashing, 
then unplug the power cord.
2. To clean the intake vents, use a small vacuum cleaner designed for 
computers and other office equipment. If you don’t have one, 
gently clean the vents with a soft brush (such as an artist’s 
paintbrush).
caution
Do not use wax, alcohol, 
benzene, thinner, or other 
chemical detergents. These 
can damage the case.
note
To order replacement air 
filters, request part number 
V13H134A07. See page 13 
for ordering information.

3. If the dirt is difficult to remove or a filter is broken, replace the 
filters as described on the next page. Contact your dealer or call 
Epson at (800) 873-7766 in the United States to obtain new ones. 
In Canada, please call (800) 463-7766 for dealer referral.
Replacing the Lamp and Air Filters
The life span of the projection lamp is about 2000 hours if 
Brightness Control in the Setting menu is set to High (default), and 
3000 hours if 
Brightness Control is set to Low. 
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message Replace the lamp appears on the screen when the 
lamp comes on and the lamp warning light   flashes orange. To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible. 
■The lamp warning light   flashes red (the lamp is burnt out).
Contact your dealer or call Epson at (800) 873-7766 in the United 
States for a replacement lamp. Request part number V13H010L31. In 
Canada, please call (800) 463-7766 for dealer referral.
Follow these steps to replace the lamp and air filters:
1. Turn off the projector.
2. When the 
Power light stops flashing, unplug the power cord.
3. Let the projector cool for at least an hour (if it has been on). The 
lamp is extremely hot immediately after use. 
note
When you get a replacement 
lamp for your projector, you 
should replace the filters.
To check how long the lamp 
has been in use, see 
page 105.
warning
Let the lamp cool fully 
before replacing it. 
In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury.

9. Grasp the handles as shown and pull the lamp straight out.
10. Gently insert the new lamp. (If it doesn’t fit easily, make sure it is 
facing the right way.) 
11. Once the lamp is fully inserted, tighten its screws and replace the 
cover, then tighten the cover screw. (The projector won’t come on 
if the lamp cover is loose.) 
12. Reset the lamp timer as described in the next section. 
Resetting the Lamp Timer
After you replace the lamp, you need to reset the lamp timer using the 
projector’s menus. 
1. Press the 
Menu button on the remote control or on the 
projector’s control panel. You see the main menu.
2. Use the  pointer button on the remote control (or the arrow 
buttons on the projector) to highlight 
Reset, then press Enter.

Transporting the Projector
The projector contains many glass and precision parts. Follow these 
guidelines to prevent damage:
■When shipping the projector for repairs, use the original 
packaging material if possible. If you do not have the original 
packaging, use equivalent materials, placing plenty of cushioning 
around the projector.
■When transporting the projector a long distance, first place it in a 
hard-shell shipping case, then pack it in a firm box with 
cushioning around the case. (An optional case is available from 
Epson; see page 13.)note
Epson shall not be liable for 
any damages incurred 
during transportation.
