Epson Multimedia Projector EB-2255U

Before cleaning any part of the projector, turn it off and unplug the power cord.

Never open any cover on the projector, except as specifically explained in this manual. Dangerous electrical voltages in the projector can injure you severely.

Clean the projector's lens periodically, or whenever you notice dust or smudges on the surface.

To remove dust or smudges, gently wipe the lens with lens-cleaning paper.

To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the lens. Do not spray any liquid directly on the lens.

Do not use a lens cleaner that contains flammable gas. The high heat generated by the projector lamp may cause a fire.

Regular filter maintenance is important to maintaining your projector. Clean the air filter when a message appears telling you the temperature inside the projector has reached a high level.; It is recommended that you clean these parts at least once every three months. Clean them more often than this if you use the projector in a particularly dusty environment.

If regular maintenance is not performed, your Epson projector will notify you when the temperature inside the projector has reached a high level.

Do not wait until this warning appears to maintain your projector filter as prolonged exposure to high temperatures may reduce the life of your projector or lamp.

Cleaning the Air Filter and Vents

Clean the projector's air filter or vents if they get dusty, or if you see a message telling you to clean them.

1. Turn off the projector and unplug the power cord.

2. 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.

The projector monitors the number of hours the lamp is used and displays this information in the projector's menu system.

Replace the lamp as soon as possible when the following occurs:

The projected image gets darker or quality declines

A message is displayed when you turn on the projector telling you to replace the lamp (the message is displayed 100 hours before the expected end of the lamp life and appears for 30 seconds)

The projector's power indicator is flashing blue and its lamp indicator is flashing orange.

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

When the lamp replacement message appears, replace the lamp with a new one as soon as possible, even if it is still working.

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.
