The audio cable is not connected
properly.Check whether the audio cable is connected properly.
(P24, 43)
The [MUTE] function is selected.  Press the [MUTE] button on the remote control. (P40)
The volume level is adjusted to the
minimum. Adjust the [VOL+] button on the remote control or top con-
trol to adjust the volume level. (P40)
An audio cable with a built-in resistor
is used. Use an audio cable without a built-in resistor.
Cause Countermeasure
The image is out of focus.Adjust the focus. (P30)
The lens cap is not removed.  Remove the lens cap. (P92)
The distance to the screen is too
short.Check whether the distance to the screen is proper. 
If the distance is shorter than about 3.9 (1.2 m), the image
cannot be brought to a focus. (P20, 85)
The projector is not placed straight in
front of the screen.  Check whether an image is obliquely projected to the
screen. A slight error in the projection angle can be cor-
rected through keystone adjustment. (P21, 31)
The projector has been moved to a
place where the difference in tempera-
ture is large. When the projector is moved from a low-temperature
place to a high-temperature place, dews may form on the
lens. Dews will evaporate a while later and the projector
will be able to project a normal image. 
Cause Countermeasure
An image is projected with its top and
bottom or left and right reversed. The ceiling mounted/rear projection setting is incorrect.
Check the Image flip H/V setting in the Display settings
menu. (P61)

Cannot project image from notebook computer
Power turns off
Cause Countermeasure
The connection cable is not connected
properly. Check whether the connection cable is properly connected
to the video terminal of the computer. (P23)
The video signal type is incorrect.  Check whether the selected signal type is correct. (P28,

The external monitor output setting on
the notebook computer is incorrect. Turn on the external monitor output on the notebook com-
puter.
To turn on the external monitor output, press the [LCD] or
[VGA] function key while pressing the [Fn] key on the key-
board of the notebook computer. (P24)
The combination of keys used to perform this operation
varies among computer manufacturers. Refer to the
Users Manual that came with your computer. 
The displayed image is not the same
as that displayed on the notebook
computer.  Check whether the dual screen (multi-display) mode is
selected on the notebook computer.
When the dual screen mode is selected, change it to the
simultaneous display mode (output setting) on the note-
book personal computer.
The output setting method varies among computer manu-
facturers. Refer to the Users Manual that came with your
computer. 
Cause Countermeasure
The air intake or exhaust vent is
blocked.Check whether the air intake or exhaust vent is blocked. 
If the air intake or exhaust vent is blocked, the temperature
inside the projector rises and the power is automatically
turned off to protect the main body of the projector. Wait
until the internal temperature lowers, and turn on the pro-
jector with the intake and exhaust vents unblocked. (P21,
76)
The fir filter is dirty. Check whether the bottom air filter is clogged with dust.
If the air filter is clogged, clean or replace the air filter.
(P76)
The lamp has burnt out (or it is defec-
tive). Check whether the lamp has burnt out. 
If the lamp has burnt out, replace it.
The lamp may be defective if it has not burnt out. Check
the lamp by replacing it with a spare lamp if you have it.
(P12, 77)
The operating temperature is
improper. Check whether the operating temperature is 5 to 35
oC.
(P13)
Others The projector may be out of order. Contact Canon dealer
immediately. (Back cover)

Glossary
Analog RGB
A signal system used to send information about R (red), G (green), and B (blue) with analog
values. It is a typical system for connecting a color monitor to a computer. Connect the
analog RGB output terminal of the computer and the DVI-I/RGB IN-1 terminal or RBG-2/
COMPONENT IN/RGB OUT terminal of this projector with a monitor cable. When the RGB
IN-1 terminal is used, select “ANALOG RGB-1” by pressing the [COMPUTER-1] button.
When the RGB IN-2 terminal is used, select “ANALOG RGB-2” by pressing the
[COMPUTER-2] button. 
Digital RGB
A signal system used to send information about individual display dots with digital values.
This system is free from deterioration of image quality because of no analog conversion.
Connect the DVI output terminal of the computer and the DVI-I/RGB IN-1 terminal of this
projector with a connection cable and select “DIGITAL RGB” by pressing the [COMPUTER-
1] button.
Video
An output terminal widely used for AV equipment. It is also called a composite output
terminal (pin terminal or RCA terminal). For more details, refer to “Composite”.
S-video
A signal system (YC separation signal) used to send a brightness signal (Y) and color signal
(C) separately. Connect the S-video terminal of AV equipment and the S-VIDEO IN terminal
of this projector with an S-video cable and select “S-VIDEO” by pressing the [VIDEO/S]
button.
Component
A signal system used to send a color signal (C) with it divided into a B-Y color difference
signal and an R-Y color difference signal. This system can project a better-quality image as
compared with the composite signal system. Connect the video terminal of AV equipment
and the RGB-2/COMPONENT IN/RGB OUT terminal with a component cable and select
“COMPONENT” by pressing the [COMPUTER-2] button.
Composite
A video signal system used to send a brightness signal (Y) and a color signal (C) together.
Connect the composite output terminal (RCA) of AV equipment and the VIDEO IN terminal of
this projector with a video cable and select “VIDEO” by pressing the [VIDEO/S] button.
sRGB
An international standard of color representation (color space) which is applied to digital
cameras, displays and others. If you select sRGB, the projector can project the best-quality
image conforming to the sRGB Standard. 
						

							89
APPENDIX
Progressive
An image display system used to display the entire screen per scan. When an interlace
signal (video signal) that displays one screen by two scans (one for odd lines and one for
even lines) is input, progressive processing is required. When the progressive function is
turned off, one screen is displayed using image signals per interlace signal, deteriorating the
vertical resolution of the image. When the progressive function is turned on, one screen is
displayed using image signals per two interlace signals, improving the vertical resolution of
the image. Turn off the progressive function when flickering and horizontal lines are
noticeable on a fast-moving picture.
Resolution
The number of dots (horizontal dots x vertical dots) that can be displayed on a computer is
called “resolution of display”. Resolution indicates the size of the display area (amount of
information).
Selecting SXGA+ (1400 dots x 1050 dots) as the display resolution of the computer allows
this projector to project high-resolution images. If your computer does not have the SXGA+
option, select the maximum resolution among the selectable options. 
Gamma Correction
A tone adjustment system used during projection of image data. The gamma correction
function works effectively when portions of an image are obscure because they are too light
or dark. 
This projector supports manual gamma correction, automatic gamma correction, and
dynamic gamma correction.
DVI-I
A digital video signal connection interface. This interface allows digital data to be sent and
received without conversion to analog data, assuring high image quality with no signal
degradation. The DVI-I (integrated) connector can be used to send and receive analog RGB
video signals in addition to digital signals.
