Maintenance and cleaning
Follow steps below to replace the lamp:
1. Power off your projector and unplug the AC pow-
er cord. Let it cool down for at least 1 hour.
2. Open the lamp cover after removing screws
holding the cover.
3. Loose all 3 screws fixing the lamp. Remove the
lamp by holding its handle.
4. Replace with a new lamp and tighten all 3
screws. Make sure the lamp has been installed
correctly. Close the lamp cover and tighten the
screw.
5. Connect your projector to an AC power source
and power it on.
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 a qualified technician or the Canon Cus-
tomer Support Center. Additionally, with ceiling-mounted projectors, the lamp
may fall out when you open the lamp cover or while you are attempting to re-
place it. During replacement, make sure no one is under the projector, and stand
to the side of the lamp cover, not directly under it.
Note:
Let your projector cool for at least 1 hour before opening the lamp cover, as
temperature within your projector is high.
Note:
Replace the lamp with a new one of the same model only when it is necessary.
Do not drop or touch the lamp! It may break and lead to personal injuries.

Precautions on lamp operation
Your projector employs high voltage lamp, which requires careful and correct operation.
Fail to do so may lead to accidents, personal injuries, or fire.
●
Useful life of lamps varies widely from lamp to lamp and depending on the environment
of use. Some lamps may fail or rupture soon after they are first used.
●
If your projector prompts you to replace lamp (by showing a lamp replacing icon) then
replace it with a new one after powering it off and it is fully cooled down. (Please re-
place lamp by strictly following steps given in this manual.)
If you keep on using the lamp after being prompted to replace it then you are exposed
to greater risks of lamp explosion.
●
Lamp may explode due to external impact and shock. Risks of explosion vary with
projector and use environment and status of the lamp.
In case of lamp explosion, take the following safety measures:
Disconnect your projector from power source immediately in case of lamp explosion. Call
authorized service center to inspect your projector and replace lamp. Make a thorough
inspection to ensure every piece of debris after explosion has been removed. Remove ev-
ery piece of debris after explosion. No one else may inspect the internal of your projector
except those authorized and well trained technician who also are familiar with its mainte-
nance. Or we shall not be held liable for the consequences.
