Precautions when replacing lamps that stop working
If the illumination suddenly stops when the projector is in use or after 
you turn it on, the lamp may be broken. In this case, never attempt to 
replace the lamp by yourself. Always request service from the Canon 
Customer Support Center. Additionally, with ceiling-mounted 
projectors, the lamp may fall out when you open the lamp cover or 
while you are attempting to replace it. During replacement, stand to the 
side of the lamp cover, not directly under it. If the lamp breaks and any 
glass shards or other pieces get in your eyes or mouth, consult a 
doctor immediately.
When replacing the lamp, turn off the projector, wait until the cooling 
fan stops, disconnect the power plug from the electrical outlet, and let 
the projector stand for at least 1 hour. Otherwise, you may get burned 
because the main unit is very hot immediately after the projector is 
turned off.
• Be sure to use the specified lamp.
• Contact the Canon Customer Support Center for further information. 
This can also be purchased from the Canon website.
• Do not touch the inner glass surface when you replace the lamp. 
Doing so may cause deterioration to the projector’s performance.
• Handle lamps with care. Impact or abrasion may cause lamps to 
rupture while they are in use. If a lamp ruptures, contact the Canon 
Customer Support Center and follow the instructions in 
“Precautions when replacing lamps that stop working” (P26).
• When replacing the lamp, do not remove any screws other than 
those specified.

Introduction to Networked Multi-Projection
■Projection Over a Network
Networked Multi-Projection (NMPJ) is a projector function enabling projection of 
computer screens over a local network. Multiple computers and multiple projectors 
can be connected, for a variety of projection scenarios.
■Split-Screen Projection of Multiple Images
Images from multiple computers can be projected at once, with the images 
projected in separate areas of a single screen.
■Projection of an Image from Multiple Projectors at Once
Images from a single computer can be projected from multiple projectors at once.
Links computers and projectors via a network connection.

■Selecting the Projection Monitor
For multi-monitor computers, you can project either the primary or secondary 
monitor.
For each computer, you can select the monitor to project.
• With some computers, it may not be possible to switch between projection of the 
primary and secondary monitor.
• The application responsiveness may decline when many computers and projectors are 
connected over the network.
• For computers that support three or more monitors, the monitor used for projection 
varies depending on the model of computer.
