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 may need to clean the air filter and air 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. 
						

							72Maintenance 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
Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter or vent on the bottom of the projector, 
clean them as described below. Dust clogs prevent proper ventilation 
and 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. 
						

							Maintenance and Transportation73
To clean the air filter and air vent, follow these steps:
1. Turn off the projector, allow it to cool down, and unplug the 
power cord.
2. To clean the filter and vent, Epson recommends using a small 
vacuum cleaner designed for computers and other office 
equipment. If you don’t have one, gently clean them using a very 
soft brush (such as an artist’s paintbrush).
You can remove the air filter to clean both sides.
If the dirt is difficult to remove or if the filter is torn, replace it. 
Contact your dealer or call Epson at (800) 463-7766 to obtain a 
new one (part number V13H134A13). 
3. If you need to clean or replace the filter, slide it off, as shown.

							74Maintenance and Transportation4. Align the new filter and slide it in until it clicks into place.
Replacing the Lamp
The projection lamp typically lasts for about 3000 hours of use 
(in high brightness mode) or 4000 hours (in low brightness mode). It 
is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The   lamp light is flashing orange. 
■The message Replace the Lamp appears on the screen when the 
lamp comes on. To maintain projector brightness and image 
quality, replace the lamp as soon as possible.
Contact your dealer or call Epson at (800) 463-7766 for a 
replacement lamp. Request part number V13H010L42.
Follow these steps to replace the lamp:
1. Press the P 
Power button twice to turn off the projector. When 
you hear the projector beep twice, unplug the power cord.
2. If the projector has been on, allow it to cool down for at least an 
hour (or until the lamp is cool). 
note
Air filters contain 
polycarbonate, ABS resin, 
and polyurethane foam. 
Dispose of used air filters 
according to local 
regulations.
note
You can check to see how 
many hours the lamp has 
been used. See page 61.
Turn off this product when 
not in use to prolong the life 
of the projector. 
warning
Let the lamp cool before 
replacing it. If the lamp 
breaks, handle the shards 
carefully to avoid injury. 
						

							Maintenance and Transportation75
3. Use the screwdriver included with the replacement lamp or a #2 
Phillips-head screwdriver to loosen the screw holding the lamp 
cover (the lamp cover is located on top of the projector).
4. Slide the cover out, then lift it off.
5. Use the screwdriver to loosen the two screws holding the lamp in 
place. (You can’t remove the screws.)

product contain mercury. 
Please consult your state and 
local regulations regarding

these screws 
						

							76Maintenance and Transportation7. Gently insert the new lamp along the guide rail. If it doesn’t fit 
easily, make sure it’s facing the correct way. Push the lamp down 
firmly where the label 
PUSH appears.
8. Once the lamp is fully inserted, tighten its screws.
9. Lower the lamp cover into place. (The opening should be almost 
covered, and the top of the cover should be flush with the top of 
the projector.) Then slide the cover closed and tighten the screw.
10. Reset the lamp timer as described in the next section.
caution
Do not touch the glass 
portion of the lamp 
assembly. Touching the glass 
could result in premature 
lamp failure.
note
Be sure to seat the lamp fully 
and secure the lamp cover. If 
the lamp is not properly 
installed or the cover is loose, 
the lamp will not turn on.

							78Maintenance and Transportation
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 as freight or checked luggage, 
first put it in a carrying case, then pack it in a firm box, using 
cushioning around the case. 
■When you are hand-carrying the projector, be sure to use a 
carrying case.
