Maintenance Maintenance
The air filter can be replaced even if the projector is installed to a ceiling.
PROCEDURE
Turn off the projector power, wait for the cool-down
 
period to end, and then disconnect the power cable.
The cool-down period lasts for about 20 seconds.
Put your finger into the recess in the knob of the air 
filter cover, and lift up the air filter cover to remove it.
Replace the air filter with a new one.
Remove the old air filter, and install the new air filter. Place the 
new air filter so that it does not slip into the air intake vent.Install the air filter cover.
First insert the tabs, and then press down on the opposite side

GlossaryFollowing is an explanation of some of the terms used in this guide which may be unfamiliar or which were not explained in the text of this guide itself. Further 
information can be obtained by referring to other commercially-available publications.
5BNCA port used to input analogue video signals.
Aspect ratio
The ratio between an images length and its height. HDTV images have an aspect ratio of 16:9 and appear elongated. The 
aspect ratio for standard images is 4:3.
Colour temperatureThe temperature of an object which is emitting light. If the colour temperature is high, the colours tend to take on a bluish 
tinge. If the colour temperature is lower, the colours tend to take on a reddish tinge.
Component video
Video signals which have the video brightness signals and colour signals separated, in order to provide better image quality. 
In high-definition TV (HDTV), it refers to images which consist of three independent signals: Y (luminance signal), and Pb 
and Pr (colour difference signals).
Composite videoVideo signals which have the video brightness signals and colour signals mixed together. The type of signals commonly used 
by household video equipment (NTSC, PAL and SECAM formats). 
The carrier signal Y (luminance signal) and chroma (colour) signal which are contained in the colour bar are overlapped to 
form a single signal.
Contrast
The relative brightness of the light and dark areas of an image can be increased or decreased in order to make text and 
graphics stand out more clearly, or to make them appear softer. Adjusting this particular property of an image is called 
contrast adjustment.
Cool-downThis is the process by which the projectors lamp is cooled down after it has become hot through use. It is carried out 
automatically when the [Power] button on either the projectors control panel or the remote control has been pressed to turn 
off the projector. Do not disconnect the power cable while cool-down is in progress, otherwise the cool-down process will not 
work properly. If the cool-down period is not allowed to finish normally, the projectors lamp and internal components will 
remain at high temperatures, and this may shorten the operating life of the lamp or cause problems with the operation of the 
projector.
Dolby Digital
A sound format developed by Dolby Laboratories. Normal stereo is a 2-channel format which uses two speakers. Dolby 
Digital is a 6-channel (5.1-channel) system which adds to this a centre speaker two rear speakers and a sub-woofer.
EMP Link21LA utility software program that allows the projector to be connected to a computer so that the computer can be used to control 
the projector. For details on acquiring the software and for instructions on using the software and compatible projector 
models, please visit the Web site http://www.epson.co.uk/support/download/projector.htm

HDTV
An abbreviation for High-Definition Television. It refers to high-definition systems which satisfy the following conditions.
 Vertical resolution of 750p or 1125i or greater (p = progressive scanning
, i = interlaced scanning
)
Screen aspect ratio
 of 16:9
Dolby Digital
 audio reception and playback (or output)
Interlaced scanningA method of image scanning whereby the image data is divided into fine horizontal lines which are displayed in sequence 
starting from left to right and then from the top to the bottom of the screen. The even-numbered lines and odd-numbered lines 
are displayed alternately.

Glossary Glossary
Progressive scanning
A method of image scanning whereby the image data from a single image is scanned sequentially from top to bottom to create 
a single image.
Refresh rateThe light-emitting element of a display maintains the same luminosity and colour for an extremely short time. Because of this, 
the image must be scanned many times per second in order to refresh the light-emitting element. The number of refresh 
operations per second is called the refresh rate, and is expressed in hertz (Hz).
Resize display
This function is used to project computer images that have a resolution more than or less than the projectors panel resolution 
to be projected so that they fill the whole of the projection area.
SDTVAn abbreviation for Standard Definition Television. It refers to standard television systems which do not satisfy the conditions 
for High-Definition Television.
Security lock
A device consisting of a projector case with a hole in it that a commercially-available theft-prevention cable can be passed 
through in order to secure the device to a table or pillar. This projector is compatible with the Microsaver Security System 
manufactured by Kensington.
Squeeze modeIn this mode, wide-screen images in 16:9 mode are compressed in the horizontal direction so that they are stored on the 
recording medium as 4:3 images.
When these images are played back by the projector in squeeze mode, they are restored to their original 16:9 format.
sRGB
An international standard for colour intervals that was formulated so that colours which are reproduced by video equipment 
can be handled easily by computer operating systems (OS) and the Internet.
SVGAA type of video signal with a resolution of 800 (horizontal) × 600 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
S-Video
A video signal which has the luminance component and colour component separated in order to provide better image quality. 
It refers to images which consist of two independent signals: Y (luminance signal), and C (colour signal).
SXGAA type of video signal with a resolution of 1280 (horizontal) × 1024 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
Sync. (Synchronization)
The signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the 
resulting images will not be of a good quality. The process of matching the phases of these signals (the relative position of the 
crests and troughs in the signal) is called synchronisation. If the signals are not synchronized, problems such as flickering, 
blurriness and horizontal interference can occur.
Tr a c k i n gThe signals output from computers have a specific frequency. If the projector frequency does not match this frequency, the 
resulting images will not be of a good quality. The process of matching the frequency of these signals (the number of crests in 
the signal) is called tracking. If tracking is not carried out correctly, wide vertical stripes will appear in the projected images.
USB
An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which 
only support relatively low data transmission speeds.
UXGAA type of video signal with a resolution of 1600 (horizontal) × 1200 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
VGA
A type of video signal with a resolution of 640 (horizontal) × 480 (vertical) dots which is used by IBM PC/AT-compatible 
computers. 
						

							87
Glossary Glossary
XGAA type of video signal with a resolution of 1024 (horizontal) × 768 (vertical) dots which is used by IBM PC/AT-compatible 
computers.
YCbCr
The carrier signal which is contained in the colour bar signal used in modern TV transmissions. The name comes from the Y 
(luminance) signal and the CbCr (chroma (colour)) signals.
YPbPrThe carrier signal which is contained in the colour bar signal used in high-definition TV (HDTV) transmissions. The name 
comes from the Y (luminance) signal and the PbPr (colour difference) signals.

List of ESC/VP21 CommandsCommand List
When a power ON command is sent to the projector, the power for the 
projector turns on. When the projector is in a command ready state, it 
returns the 3Ah (:) code. Furthermore, when command processing is 
complete, the projector also returns a : code.
The : code status can be used to determine whether the projector is ready 
or busy. If command processing terminates with an error, an error message 
is output and then the : code is sent.
