Maintaining and Transporting the Projector57
Maintaining and 
Transporting the Projector
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 on the bottom of the 
projector. A clogged air filter can block ventilation needed to cool the 
projector and keep it from 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 service 
person.
This chapter covers the following:

Cleaning the lens

Cleaning the projector case

Cleaning and replacing the air filter

Replacing the lamp

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.

							58Maintaining and 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 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 neutral detergent. Then wipe the case. 

Do not use alcohol, benzene, thinner, or other chemical 
detergents. These can damage the case.

							Maintaining and Transporting the Projector59
Cleaning and Replacing the Air Filter 
Clean the air filter at the bottom of the projector after every 100 hours 
of use. If it is not cleaned periodically, it can become clogged with 
dust, preventing proper ventilation. This can cause overheating and 
damage the projector. To clean the air filter, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug the 
power cord.
2. Turn the projector on its side so that the handle is on top and you 
can access the filter easily. 
3. To clean the filter, EPSON recommends using a small vacuum 
cleaner designed for computers and other office equipment. If you 
don’t have one, gently clean the filter using a very soft brush (such 
as an artist’s camel-hair brush).
4. If the dirt is difficult to remove or if the filter is torn, replace it. 
Contact your dealer or call EPSON at (800) 873-7766 in the 
United States and Canada to obtain a new one. 
Before removing the filter, make sure the projector is on its side as 
shown (not upside down) to prevent dust from falling inside. 
Then release the latch to remove the filter.

note
When you get a replacement 
lamp for your projector, a 
new air filter is included. 
You should replace the filter 
when you replace the lamp.

							60Maintaining and Transporting the Projector5. To install the new filter, first insert its tabs as shown, then press 
on the latch until it clicks in place.
Replacing the Lamp 
The projection lamp typically lasts for about 1500 hours of use. It is 
time to replace the lamp when:

The projection image gets darker or starts to deteriorate.

The lamp warning light   is flashing red or orange. 

The message LAMP REPLACE appears on the screen when the 
projector lamp comes on (after about 1400 hours of use). To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible.
Contact your dealer or call EPSON at (800) 873-7766 in the United 
States and Canada for a replacement lamp. Request part number 
ELPLP12.

Enter button (remote control) to select Yes. 
4. Press 
Enter to reset the timer.
Transporting the Projector
The projector contains many glass and precision parts. If you need to 
transport it, please follow these packing guidelines to prevent damage 
to the projector: 

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 for business use, first put it in a 
hard-shell carrying case (such as an optional EPSON case), then 
pack it in a firm box, using cushioning around the case. 

When hand-carrying the projector, store it in a carrying case, such 
as one of the optional cases offered by EPSON.
If you want to store the remote control inside the projector’s carrying 
case, be sure to turn it off using the switch on its side. This prevents 
the batteries from discharging if something inside the case presses 
against one of the remote control’s buttons.
note
EPSON shall not be liable 
for any damages incurred 
during transportation.
