Maintaining the projector
Replacing the lamp module
As the projector operates over time, the brightness of the projector lamp
gradually decreases and the lamp becomes more susceptible to breakage. You can
install a new lamp at any time to bring the projector up to factory-fresh
brightness. We recommend replacing the lamp if a warning message is displayed.
Å Replacing the lamp module requires special consideration:
■ To reduce the risk of injury, be careful when removing the lamp module as
broken glass might be present. For a ceiling installation, wear goggles and
gloves when removing the lamp module. If the lamp is broken, contact HP
about repairs that might be required due to glass fragments.
■ 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 at http://www.eiae.org.
■ Because the lamp assembly operates at a very high temperature, wait 30
minutes before removing the lamp module.
1. Turn off the projector and allow it to cool for 30 minutes.
2. Unplug the power cord.
3. Loosen the 3 screws 1 on the front cover and pull out the front cover until
the tab 2 at the right end comes out of the projector 3 .
4. Loosen the two screws 4 on the lamp module, and pull out the module 5 .
