Cleaning and Replacing the Filters
The projector has several filters that should be cleaned periodically to 
remove trapped dust. If the filters become clogged, the projector can 
overheat and damage can result. Clean the filters approximately every 
three months, or after every 100 hours of use; clean them more often 
if you use the projector in a dusty environment. 
Cleaning the Lamp Filter
To clean the lamp filter, follow these steps:
1. Remove the lamp as described on page 94.
2. Hold the shutter open and use a vacuum cleaner (a small one 
designed for computers and office equipment) to remove any dust 
from the wire mesh filters inside. 
3. Insert the lamp back into the projector, tighten its screws, and 
replace the lamp cover.
caution
Avoid touching the glass 
portion of the lamp. Oils 
transferred from your hands 
can cause the lamp to 
overheat and fail 
prematurely.

Cleaning the Air Intake Filters
To clean the air intake filters, follow these steps:
1. Turn off the projector and unplug the power cord.
2. Use a computer vacuum to clean the filters. If you don’t have one, 
gently clean the filters with a soft brush, such as an artist’s 
paintbrush.
3. If the dirt is difficult to remove or a filter is broken, replace the 
filters as described in the next section. Contact your dealer or call 
EPSON at (800) 873-7766 in the United States to obtain new 
ones. In Canada, please call (800) 463-7766 for dealer referral.
Replacing the Filters
1. Turn the projector over (unless it’s ceiling-mounted). 
2. Remove the filters by sliding them out to the sides.
note
When you get a replacement 
lamp for your projector, new 
air filters are included. You 
should replace the filters 
when you replace the lamp.

3. Remove each filter from its holder by releasing the two tabs, as 
shown.

each side. 
5. Slide the assembled filters back into the projector.

Replacing the Lamp
The projection lamp typically lasts from 2000 to 3000 hours, 
depending on the Brightness Control setting used (see page 64). 
Selecting the low brightness setting helps extend the lamp’s life.
It is time to replace the lamp when: 
■The projected image gets darker or starts to deteriorate.
■The message LAMP REPLACE appears on the screen and the 
lamp warning light   flashes orange.
■The lamp warning light   flashes red (the lamp is burnt out).
Contact your dealer or call EPSON at (800) 873-7766 in the United 
States for a replacement lamp. Request part number 
V13H010L23. In 
Canada, please call (800) 463-7766 for dealer referral.
Follow these steps to replace the lamp:
1. Turn off the projector.
2. When the power light stops flashing, unplug the power cord.
3. Let the projector cool for at least half an hour (if it has been on). 
The lamp is extremely hot immediately after use. 
4. If the projector is mounted on the ceiling, remove the rear cover. 
note
You can check how long 
the lamp has been in use 
(see page 96).
Lamp life results will vary 
depending on 
environmental conditions 
and usage. Turn the 
projector off when not in 
use. Continuous 24-hour-
a-day use may reduce the 
overall life of this product.
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.

5. Loosen the lamp cover screws (you don’t need to take them out all 
the way). Then remove the cover.
6. Loosen the three screws holding the lamp in place (you can’t 
remove them).
7. Grasp the wire handle as shown and pull the lamp straight out.
8. Gently insert the new lamp. 
9. Once the lamp is fully inserted, tighten its screws and replace the 
cover. (The projector won’t come on if the lamp cover is loose.) 
10. Reset the lamp timer as described in the next section. 
caution
Avoid touching the glass 
portion of the new lamp. 
Oils transferred from your 
hands can cause the lamp to 
overheat and fail 
prematurely.

Transporting the Projector
The projector is heavy and contains many glass and precision parts. 
Follow these guidelines to prevent injury or damage:
■When hand-carrying the projector, you should use the handle to 
lift it only a short distance (for example, to set it on a table). To 
move the projector over longer distances, place it on a rolling cart 
or use a dolly. 
■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 a long distance, first place it in a 
hard-shell shipping case, and then pack it in a firm box, placing 
cushioning around the case. (An optional shipping case is 
available from EPSON; see page 12.)
■It’s a good idea to turn off the remote 
control before packing it in a carrying case. 
This prevents the batteries from discharging 
if something presses against one of the 
buttons. 
warning
The projector is heavy 
(24 lbs.). Use care when 
handling it to prevent 
physical strain or injury.

Checking the Projector Status
If you’re having a problem with the projector, check the following: 
■Check the lights on the top of the projector (as described below). 
The lights can often tell you about the nature of the problem.
■You can also view the About menu screen (page 103). This gives 
you information about the lamp life and currently selected input 
signal. 
What To Do When the Lights Flash
The lights on top of the projector indicate the projector’s status and 
let you know when a problem occurs.
If the projector seems to be indicating a problem, locate the pattern of 
lights in the table on the next page, then follow the recommended 
solutions.
