Recalling a Memory Setting
When you want to use a saved memory setting, press one of the 
memory buttons on the remote control. This applies the saved settings 
to the image currently being projected on the screen.
If the same video source is connected to the projector the next time 
you turn it on, the projector uses the same saved memory setting in 
effect the last time it was on.
Once you have saved a memory setting, you cannot erase it. However, 
you can change it; just follow the same procedure as for setting it the 
first time.

Maintaining 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 to prevent 
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

Storing the projector

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. 
						

							40Maintaining the Projector
Cleaning the Lens
Clean the lenses 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 lenses, 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 wax, alcohol, benzene, thinner, or other chemical 
detergents. These can damage the case.
Cleaning and Replacing the Air Filter
Clean the air filter on 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 and allow it to cool down.
2. Turn off the switch on the back of the projector.
3. Unplug the power cord.
4. Stand the projector on end with the handle on top to keep dust 
and dirt from falling inside.
caution
Do not rub the lens with any 
harsh materials.
note
The inside of the projector 
should be cleaned by a 
qualified technician every 
two years to remove dust that 
may collect inside. Contact 
your dealer or service 
representative.  
						

							Maintaining the Projector41
5. 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).
If the dirt is difficult to remove or if the filter is broken, replace it. 
Contact your dealer or call EPSON at (800) 873-7766 in the 
United States to obtain a new one. In Canada, call (800) 
463-7766 for dealer referral.
6. If you need to replace the filter, lift the tab 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.
Lift the tab 
						

							42Maintaining the Projector7. To install a new filter, first insert the tabs, then press down until it 
clicks in place.
Replacing the Lamp
The projection lamp typically lasts for about 3000 hours of use. It is 
time to replace the lamp when:

The projection image gets darker or starts to deteriorate.

The lamp light   is red or flashing orange.

The message LAMP REPLACE appears on the screen when the 
lamp comes on (after about 2900 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 for a replacement lamp. Request part number 
V13H010L17. In 
Canada, call (800) 463-7766 for dealer referral.
Be sure to read the “Important Safety Instructions” on page 65 before 
replacing the lamp; then follow these steps:
1. Turn off the projector and wait for it to cool down (until the light 
stops flashing).
2. Turn off the power switch on the back of the projector and 
unplug the power cord.
3. Allow the projector to cool for at least half an hour (if it has been 
on).
warning
Be extremely careful when 
removing the lamp module. 
In the unlikely event that the 
bulb has ruptured, small glas
s 
fragments may be present an
d 
should be removed with 
caution.
If your projector is mounted 
on the ceiling, you should 
take it down before accessing 
the lamp compartment. This 
will make it easier for you to 
replace the lamp and 
minimize the chance of any 
small glass fragments 
dropping from the projector.
warning
Let the lamp cool before 
replacing it. If the lamp 
breaks, handle the shards 
carefully to avoid injury.

4. Use a screwdriver to slide the latch and pop open the lamp cover. 
Then lift up and remove it.
5. Use the screwdriver to loosen the two silver screws holding the 
lamp in place. (You can’t remove these screws.)
6. Grasp the lamp as shown and pull it straight out.
caution
Do not touch the glass 
portion of the lamp assembly. 
Touching the glass could 
result in premature lamp 
failure. 
						

							44Maintaining the Projector7. Gently insert the new lamp and tighten its screws.
8. To replace the lamp cover, insert the tabs and then snap the cover 
into place. (The projector won’t work if the lamp cover is loose.)
After replacing the lamp, you need to reset the lamp timer as described 
in the next section.
Resetting the Lamp Timer
1. Press the Menu button on the projector or the remote control.
2. Select the 
About menu.
3. Select 
Reset Lamp Timer. You see this prompt:
warning
The lamp component 
contains mercury. Please 
consult your state and local 
regulations regarding proper 
disposal and do not place in a 
waste stream. 
						

							Maintaining the Projector45
4. Select Yes and press Select.
5. When you’re finished, press 
Esc or Menu. 
The lamp usage timer doesn’t register until you’ve  used the  lamp  for at 
least 10 hours.
Storing the Projector
If you need to store the projector for a while, do the following:

Make sure the temperature and humidity of the storage area are 
within the recommended range for the projector (14 to 140 °F 
[–10 to 60 °C] and 10 to 90% relative humidity).

Package the projector in its original packaging or equivalent (as 
described in the following section).

Attach the lens cover and retract the feet.

Remove the batteries from the remote control.
Transporting the Projector
The projector contains many glass and precision parts. If you need to 
transport it, 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. Be sure the carrier company is capable of 
transporting fragile equipment and is aware that the projector is 
fragile.

When transporting the projector a long distance, first put it in a 
carrying case (such as an optional EPSON case), then pack it in a 
firm box, using cushioning around the case.

When you are hand-carrying the projector, use the carrying 
handle.
note
EPSON shall not be liable 
for any damages incurred 
during transportation.
