Maintaining the Projector
To clean the projector lens
■
To minimize the risk of damaging or scratching the lens surface, blow dust
particles off the lens with clean, dry, deionized air.
If this method does not work, use the following method:
■
Wipe the lens in a single direction with a clean, dry cloth. Do not wipe back and
forth across the lens.
If the cloth is dirty or smears the lens, wash the cloth. If the cloth is still dirty after
washing it or the fabric is damaged, replace it.
CAUTION: Cleaning requires special consideration:
Ä
■ Do not spray any type of fluid or cleaner directly on the lens surface. Cleaners
might damage the lens.
■ Do not use fabric softener when washing a cleaning cloth or softener sheets
when drying the cloth. Chemicals on the cloth might damage the surface of the
lens.
■ Do not store a cleaning cloth in contact with the lens for a long time because
doing so contaminates the lens with dye from the cloth. The cloth can be
contaminated if left in the open air.
To replace the lamp module
WARNING: Replacing the lamp module requires special consideration:
Å
■ To reduce the risk of injury, be careful when removing the lamp module as
broken glass might be present in the unlikely event the lamp is broken. If the
lamp is broken, contact HP about repairs that might be required.
■ The lamp contains a small amount of mercury. If the lamp breaks, adequately
ventilate the area where the breakage occurred. Disposal of this lamp might be
regulated due to environmental considerations. For disposal or recycling
information, contact your local authorities or the Electronic Industries Alliance
(http://www.eiae.org).
■ Because the lamp assembly operates at a very high temperature, wait
30 minutes before removing the lamp module.
