5 Securely insert the air filter all the way
into the projector.
Cleaning the Air Filter
The air filter protects the lens and mirror inside the projector from dust and dirt. Should
the air filter become clogged with dust, the projector may be damaged since it will block
the air flow into the projector and raise the internal temperature of the projector. The fol-
lowing screen is displayed when turning on the projector if the air filter needs to be
cleaned (after approx. 300 hours). Clean the air filter if such is the case.
• Hook your finger into the air filter handle on the side of the projector, and remove the air
filter. Then use a vacuum cleaner to remove the dust.
• Bring the vacuum cleaner nozzle directly close to the side intake vent and the bottom
exhaust vent in order to clean them.
• If the filter replacement screen is displayed when turning on the projector after cleaning
the air filter, select [Yes] and press OK. The filter replacement screen will disappear.
• Handle the air filter carefully. If damaged, the air filter will not work properly.
• When the lamp is replaced, it is recommend that you also replace the air filter.
• Contact the Canon Customer Support Center for further information.
