Picture qual settingSelect one of the following options, depending on your 
preferred image quality and frame rate.
High : Projects at a lower frame rate while 
emphasizing image quality. Select this 
mode if lower image quality is not 
acceptable.
Medium : Projection with image quality and frame 
rate balanced.
Low : Projects at lower image quality to maintain 
a high frame rate. Select this mode to 
reduce the network bandwidth used for 
projection.
RealOn : Projection matching the computer display 
resolution. Available under the following 
conditions.
When projecting from a single computer—
or during projection from multiple 
computers, when projecting an enlarged 
image from one computer—at a display 
resolution lower than the projector 
resolution.
Off : Automatically adjust the projection size to 
match the projector screen size.
Projection typeNormal : Although some windows cannot be 
projected, the cursor on the computer 
monitor will not flash.
Advanced : Most windows can be projected, but the 
cursor on the computer monitor will flash. 
(Only the cursor on the computer monitor 
will flash, not the cursor in projected 
images.)
NicknameNickname specified when creating or joining sessions. 
Cannot be changed during sessions. This option is not 
shown in Direct or Broadcast Modes.
Multicast addressThe multicast address used in Broadcast Mode can 
be changed. Use this setting to change the multicast 
address if it conflicts with that of other network 
equipment. This option is only shown in Broadcast 
Mode.

Tips for Better Networked Projection
■Avoid Exceeding Connection Limits
The maximum number of computers and projectors that can be connected varies 
by mode. When this limit would be exceeded, it is not possible to add computers or 
projectors to a session. Thus, if the total number of computer users requesting to 
join a session at the same time would exceed the limit, their requests may be 
denied. In this case, an error message is displayed on the computers that could not 
join the session.
Similarly, if the total number of projectors users attempt to add to a session at the 
same time would exceed the limit, their requests may be denied. In this case, a 
message is displayed on computers that could not add projectors, indicating that 
the projector list has been updated.
■Operation if Devices Are Disconnected
If the connection is lost (for example, if a LAN cable is accidentally disconnected), 
the affected computer or projector leaves the session. Disconnection of essential 
computers or projectors will terminate a session.
For example, in Classroom Mode, disconnection of the presenter’s computer will 
terminate the session.
■If Projectors Cannot Be Detected
If projectors cannot be detected or no image is displayed (except for the cursor) 
when you are attempting to connect to projectors in other subnets in Broadcast 
Mode, make sure the router supports multicast routing. Routers that do not support 
IPv4 multicast routing cannot be used to connect to projectors in other subnets in 
Broadcast Mode. Note that the router must be set up to route multicast addresses 
used by the application.
In Broadcast Mode, the following message is displayed if no signal is received from 
computers for 30 seconds. The projector IP address and name are shown in the upper 
left. 
						

							276
Restrictions
■Router Connections
Although the application can also link computers and projectors over a network via 
a router, operation is only ensured over one router hop. Note that before projecting 
from projectors in other subnets in Broadcast Mode, you must configure the router’s 
multicast routing settings. For details, ask your network administrator.
■Security Dialog Box Projection
The application cannot be used to project the Windows Security dialog box, 
normally accessed by pressing Ctrl+Alt+Del.
■Screen Capture Software
It may not be possible to start the application while software that restricts screen 
captures is running.
■Animated Cursors
Animation of animated cursors is not projected.
■Alternative Cursors
Cursors used by some software may not be projected correctly. In this case, an 
arrow pointer is projected.
■Projection Restrictions
Some windows and icons displayed on computers cannot be projected. Although 
switching the projection type to advanced will enable projection of more elements, 
not all elements can be projected even in this case.
Projected images may not always match the computer screens.
■Network Bandwidth 
Some network conditions may cause a delay in projection.
■Projection through Firewalls 
Some application functions may not be available in environments where Windows 
Firewall or other software restricting network communication are installed.
■Application Display 
Application display may be distorted if you have adjusted the screen resolution in 
Windows.

Troubleshooting
LED Indicator Meanings
When there is a problem with the projector, the LED indicator on the side of the 
projector illuminates or flashes continuously after the projector is turned off.
• Wait until the cooling fan stops and disconnect the power plug from the electrical outlet before 
dealing with the problem.

WARNING and 
TEMP are lit.Temperature 
abnormalityThe temperature inside the projector is too high 
for some reason or the outside air temperature is 
higher than the operating range. If the problem is 
inside the projector, check whether the projector 
is installed and operating normally, unplug the 
projector from the power outlet to cool down the 
projector interior and then restart projection. If the 
air intake or exhaust vent is blocked, remove the 
obstacle. If the same warning occurs again, there 
may be a malfunction in the projector. Contact 
the Canon Customer Support Center.
WARNING and 
LAMP are lit.Faulty lamp The lamp does not illuminate. Turn the power off 
and then back on and check whether or not the 
lamp illuminates. Also, check whether the air 
intake or exhaust vent is blocked, and whether 
the air filter is clogged with dust. The warning 
may indicate if the air flow in and out of the 
projector is blocked, or if the internal temperature 
of the projector rises. If the air filter is clogged, 
clean or replace the air filter. (P199, P200) If the 
lamp does not illuminate, replace it. If the same 
warning occurs again, there may be a 
malfunction in the lamp drive circuit. Contact the 
Canon Customer Support Center.
WARNING

LAMP is lit.Faulty lamp 
coverThe lamp cover is open. Unplug the projector 
from the power outlet, then install the lamp cover 
correctly and turn on the projector again.
If the lamp cover has been installed properly, 
there may be a malfunction in the lamp cover 
detection switch. Contact the Canon Customer 
Support Center.

cooling fanThere may be a malfunction in the cooling fan or 
another component. Unplug the projector from 
the electrical outlet, then plug it back into the 
outlet and turn on the projector again. Contact 
the Canon Customer Support Center if the same 
warning occurs again.
