Warning: This procedure requires careful handling of the projector lamp. Ensure you have read and understood all the steps before proceeding.

Is the projected image darker or quality declined?

Is there a message displayed when you turn on the projector telling you to replace the lamp?

Is the projector's power indicator flashing blue and its lamp indicator flashing orange?

Warning: If you continue to use the lamp after the replacement period has passed, the possibility that the lamp may explode increases.

Warning: Do not repeatedly turn off the power and then immediately turn it back on. Turning the power on and off frequently may shorten the lamp's operating life.

Warning: Always have a spare lamp unit ready in case it is needed.

Warning: We recommend the use of genuine Epson replacement lamps. The use of non-genuine lamps may affect projection quality and safety.

Warning: Let the lamp fully cool before replacing it to avoid injury.

Warning: Do not use canned air. The gases may leave a flammable residue or push dust and debris into the projector's optics or other sensitive areas.

Turn off the projector and unplug the power cord.

Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as a paintbrush).

You can remove the air filter so that you can clean both sides. Do not rinse the air filter in water, or use any detergent or solvent to clean it.

If dust is difficult to remove or the air filter is damaged, replace the air filter.
