							Fine-Tuning the Projector113
Multi-screen Color Adjustment
If you are using multiple projectors in the same room (for example, 
with the EasyMP multi-screen display function or a distribution 
amplifier), you can match the color and brightness between them.
To match the display colors as closely as possible, first make sure that 
all the projectors are set to the same Color Mode (see page 100) and 
Brightness Control setting (see page 104). Then follow these steps:
1. Assign a different ID to each projector so that you can use the 
remote control to adjust each projector individually. See page 37 
for instructions.
2. Select 
Multi-screen in the projector’s Extended menu.
3. Start by selecting the same 
Adjustment Level for two projectors. 
Each adjustment level, 1 through 5, displays a screen that lets you 
adjust the color and brightness at a different level of projector 
output (luminance).
4. Adjust the 
Brightness Correct and Color Correct settings for 
one projector so that its brightness and color tone match that of 
the other projector.
5. Select the next 
Adjustment Level for both projectors, and adjust 
the brightness and color in the same way so the projectors match. 
Repeat until all five levels have been adjusted.
6. If you are using additional projectors, repeat this process to match 
projector 3 to projector 2, projector 4 to projector 3, and so on.
tip

view the actual image. Press 
Enter again to switch back 
to the Adjustment Level 
screen.
note
In some cases, the brightness 
and color tone may not 
match completely even after 
correction.

Maintaining the Projector
Your projector needs little maintenance. All you have to do is keep 
the lens clean. You may also need to clean the air filter and vent. A 
clogged air filter or vent can block ventilation needed to cool the 
projector.
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 the air filter and vent
■Replacing the lamp and air filter
■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 
cover. 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. 
						

							116Maintaining the Projector
Cleaning the Lens
Clean the lens whenever you notice dirt or dust on the surface.
To remove dirt or smears on the lens, use lens-cleaning tissue. If 
necessary, moisten a soft cloth with lens cleaner and gently wipe the 
lens.
Cleaning the Projector Case
Before you clean the case, 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.
caution
Do not use wax, alcohol, 
benzene, paint thinner, or 
other chemical detergents. 
These can damage the case.
Never spray a liquid of any 
kind directly on the 
projector or its lens. Always 
apply it to a cloth first. 
						

							Maintaining the Projector117
Cleaning the Air Filter and Vent
Your projector includes an air filter to ensure the best performance. If 
dust collects on the air filter (on the side of the projector) or vent (on 
the front of the projector), clean them as described below. Dust clogs 
prevent proper ventilation and can cause overheating and damage the 
projector. 
Follow these steps:
1. Turn off the projector. Wait for the P
Power light to stop 
flashing, then unplug the power cord.
2. To clean the intake vent and filter, use a small vacuum cleaner 
designed for computers and other office equipment. If you don’t 
have one, gently clean the vent with a soft brush (such as an 
artist’s paintbrush).
You can remove the air filter to clean both sides.
3. If the dirt is difficult to remove or the filter is broken, replace the 
filter as described on page 120. Contact your dealer or call Epson 
at 800-GO-EPSON (800-463-7766) to obtain a new filter. 
note
To order replacement air 
filters, request part number 
V13H134A19. See page 12 
for ordering information.

Replacing the Lamp and Air Filter
The life span of the projection lamp is about 3000 hours if 
Brightness Control in the Setting menu is set to High (default), and 
4000 hours if 
Brightness Control is set to Low. 
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message Replace the lamp appears on the screen when the 
lamp comes on and the lamp warning light   flashes orange. To 
maintain projector brightness and image quality, replace the lamp 
as soon as possible. 
■The lamp warning light   flashes red (the lamp is burnt out).
Contact your dealer or call Epson at 800-GO-EPSON 
(800-463-7766). Request part number V13H010L48. 
Follow these steps to replace the lamp and air filter:
1. Turn off the projector.
2. When the P
Power light stops flashing, unplug the power cord.
3. Let the projector cool for at least an hour (if it has been on). The 
lamp is extremely hot immediately after use. 
note
When you get a replacement 
lamp for your projector, you 
should replace the filter.
To check how long the lamp 
has been in use, see 
page 127.
Turn off this product when 
not in use to prolong the life 
of the projector. 
warning
Let the lamp cool fully 
before replacing it. 
In the unlikely event that 
the lamp has broken, small 
glass fragments may be 
present and should be 
removed carefully to avoid 
injury.
If the lamp is used after the 
replacement period has 
passed, the possibility that 
the lamp may break 
increases. When a lamp 
replacement message 
appears, replace the lamp 
with a new one as soon as 
possible, even if it is still 
working.
