Maintenance

This section describes maintenance tasks such as cleaning the projector and replacing consumable parts.

Cleaning

You should clean the projector if it becomes dirty or if the quality of projected images starts to deteriorate.

Be sure to read the separate Safety Instructions/World-Wide Warranty Terms booklet for details on safe handling of the projector during cleaning.

Cleaning the air filter and air intake vent

If the air filter or air intake vent becomes blocked with dust, the message "The projector is overheating. Clean or replace the air filter and lower the room temperature" will be displayed and you must clean the filter or vent.

To do so turn the projector upside-down and use a vacuum cleaner.

If dust collects on the air filter or the air intake vent, it can cause the internal temperature of the projector to rise, and this can lead to problems with operation and shortening of the optical engine's service life. It is recommended that you clean these parts at least once every three months. Clean them more often than this if using the projector in particularly dusty environments.

Cleaning the projector case

Clean the projector case by wiping it gently with a soft cloth.

If the projector is particularly dirty, moisten the cloth with water containing a small amount of neutral detergent, and then firmly wring the cloth dry before using it to wipe the projector case. Then wipe the case again with a soft, dry cloth.

Do not use volatile substances such as wax, alcohol or thinner to clean the projector case. These can cause the case to warp and make the coating finish peel off.

Cleaning the lens

Use a commercially-available air blower, or use a lens cleaning paper to gently wipe the lens.

Do not rub the lens with harsh materials or subject the lens to shocks, as it can easily become damaged.
