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.
WARNING! 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. If the lamp is broken, contact HP about repairs that might be required
due to glass fragments.
• This digital projector lamp contains a small amount of mercury. If the lamp breaks,
adequately ventilate the area where the breakage occurred, discard any nearby food and
drink, and thoroughly clean the table surface around the projector. Wash your hands after
cleaning the area or handling a broken lamp. Disposal of this lamp may be regulated due
to environmental considerations. For disposal or recycling information, please contact your
local authorities or the Electronic Industries Alliance (www.eiae.org). You can find safety
information about the lamp at:

• 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. Turn the projector over onto a soft surface.
4. Loosen the two screws
