Using the Projector’s Security Features
To prevent unauthorized use of the projector, you can do the 
following:
■Create an identifying user logo that is displayed at startup and/or 
when the 
A/V Mute button is pressed
■Assign a password to prevent the projector from being turned on, 
prevent your startup screen from being changed, and lock 
network settings.
■Disable the projector’s buttons; this is useful, for example, if 
you’re projecting in a classroom and you want to ensure that no 
one touches the projector’s buttons while you’re using the remote 
control
■Install an anti-theft lock.
If you create a user’s logo for the projector, you can lock the logo on so 
it is displayed as the startup screen and/or AV/Mute screen. 
Unauthorized users cannot turn it off or change it. This feature is 
intended to discourage theft and provides a way to identify the 
projector should it be stolen. 
If you assign the projector a password, a screen appears requesting the 
password whenever the projector is turned on. If you enter the 
password incorrectly three times in succession, the projector’s 
operation is locked and you’ll need to disconnect the power cord, then 
reconnect it to redisplay the password screen. If an incorrect password 
is entered 30 times in a row, the projector is locked and you’ll need to 
contact Epson to unlock it. See “Where To Get Help” on page 87.
If someone else will be using the projector for awhile but you want to 
make sure that person returns it by a certain time, you can temporarily 
disable the password for a set period. When that time has elapsed, the 
password is reactivated and must be entered before the projector can 
be used.
When you enable the Operation Lock feature, all of the projector’s 
buttons (
Full Lock) or all of the buttons except the P Power button 
(
Operation Lock) are disabled.
note
If you should happen to 
enable the password before 
you set one and you see the 
prompt to enter the password, 
enter the default password 
0000 to proceed.

Creating Your Own Screen Logo
You can transfer any image on your computer to the projector, and 
then use it as the startup screen and/or the screen that is displayed 
when you press the 
A/V Mute button. The image can be a company 
logo, slogan, photograph, or any other image you want to use. The 
projector considers this image the “User’s Logo.” 
Follow these steps to capture the image and transfer it to the projector:
1. Display the image you want to use on the projector. You can use 
an image from a computer or video source, such as a DVD player. 
2. Press the 
Menu button and select the Extended menu.
3. Use the down arrow button and press 
Enter to select User’s 
Logo
.

image as a user’s logo, select 
Yes and press Enter. A selection box 
displays over the image.
5. Use the arrow buttons on the projector or remote control to select 
the area of the image you want to use. Once you have selected the 
area, press 
Enter.
6. When you see the message 
Choose this image as the User’s 
Logo?
, choose Yes and press Enter. If you want to change the 
area selected, select 
No, press Enter and repeat steps 5 and 6. 
note
If the User’s Logo Protect 
function is 
ON, you see a 
message that the logo cannot 
be recorded. You’ll need to 
disable the User’s Logo 
Protect function before you 
can create or change the 
User’s Logo. See page 65.

Maintenance and 
Transportation
Your projector needs little maintenance. All you need to do on a 
regular basis is keep the lens clean. Any dirt or smears on the lens may 
show up on your projected image. 
You also need to periodically clean the air filter and the air intake and 
exhaust vents. A clogged air filter or air vent can block ventilation 
needed to cool the projector and cause overheating. 
The only parts you should replace are the lamp and air filter. 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 and replacing the air filter
■Replacing the lamp
■Resetting the lamp timer
■Transporting the projector
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 
and filter covers. 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. 
						

							70Maintenance and Transportation
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 paper. If 
necessary, moisten a soft cloth with lens cleaner and gently wipe 
the lens surface.
Cleaning the Projector Case
Before you clean the case, first 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 mild detergent. Then wipe the case. 
■Do not use wax, alcohol, benzene, paint thinner, or other 
chemical detergents. These can damage the case.
Cleaning and Replacing the Air Filter
Clean the air filter and air intake and exhaust vent on the bottom of 
the projector 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. 
When the filter and vent are clogged, the projector displays the 
message 
The projector is overheating. Make sure nothing is 
blocking the air vent, and clean or replace the air filter.
caution
Do not use glass cleaner to 
clean the lens.
