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 will show up on your projected image. 
You also need to clean the air filter on top of the projector 
periodically. 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:
nCleaning the lens
nCleaning the projector
nCleaning the air filter
nReplacing the lamp
nTransporting the projector
warning
Before cleaning 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. 
						

							60Maintaining and Transporting the Projector
Cleaning the Lens 
Clean the lens whenever you notice dirt or dust on the surface.
nLightly wipe the lens surface with a soft, dry, lint-free cloth. 
nTo remove dirt or smears, moisten a soft cloth with an 
alcohol-based cleaner and gently wipe the lens surface.
Cleaning the Projector 
Before you clean the projector, make sure you turn it off and 
unplug the power cord. 
nTo remove dirt or dust, wipe the outside with a soft, dry, 
lint-free cloth. 
nTo remove stubborn dirt or stains, mo isten a soft clo th with 
water and a neutral detergent. Then wipe the outside of the 
projector. 
nDo not use alcohol, benzene, thinner, or other chemical 
detergents. These can cause the projector to warp.
Wipe here to 
clean the lens. 
						

							Maintaining and Transporting the Projector61
Cleaning the Air Filter 
Clean the air filter after every 100 hours of use, or if the
 temperature warning light on top of the projector turns red. 
If the filter is not cleaned periodically, it can become clogged 
with dust, preventing proper ventilation. This can cause 
overheating and damage the projector. Follow these steps to 
clean the filter:
1. Turn off the projector and unplug the power cord.
2. Pull up on the filter cover tab to release the cover. You may 
need to use a small screwdriver to pry it off. 
3. Remove the cover.
The filter is attached to the inside of the cover. 
4. To clean the filter, EPSON recommends using a small 
vacuum cleaner designed for computers and other office 
equipment. If you don’t have one, use a dry, lint-free cloth. 
5. If the dirt is difficult to remove or if the filter is torn, 
replace it. Contact your dealer to obtain a new filter. 
6. Snap the filter cover back into place when you’re done.
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.

Replacing the Lamp   
The projection lamp typically lasts for about 2000 hours of use. 
It is time to replace the lamp when you see the following:
nThe projected image gets darker or starts to deteriorate.
nThe   lamp warning light on top of the projector is 
either red or flashing orange. 
nThe message LAMP REPLACE appears on the screen when 
the projector lamp comes on. 
This happens after about 2000 hours of use. To maintain 
projector brightness and image quality, replace the lamp as 
soon as possible after you see the message.
Contact your dealer or call EPSON Accessories at 
(800) 873-7766 in the United States and Canada for a 
replacement lamp. Use the following part number when you 
order a lamp:
nELPLP10B (PowerLite 700c/500c)
nELPLP10S (PowerLite 710c)
Follow these steps to replace the lamp:
1. Turn off the projector and allow it to cool, then unplug the 
power cord.
2. Before removing the lamp, wait approximately one hour 
until the projector is fully cooled down.
3. Turn the projector upside-down to access the lamp 
compartment.
warning
Let the lamp cool before 
replacing it. To avoid 
premature lamp failure, do 
not touch the glass portion 
of the lamp assembly.

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: 
nWhen 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.
nWhen transporting the projector for business use, first put 
the projector in a carrying case (such as an optional 
EPSON accessory case), then pack it in a firm box, using 
cushioning around the case. 
nWhen you are hand-carrying the projector, be sure to store 
it in a carrying case (such as the optional case available from 
EPSON).
note
EPSON shall not be liable 
for any damages incurred
