For best lamp performance, there must be adequate air flow through and around the lamp module. A build up of
dust or dirt will reduce the air flow and shorten lamp life and lamp performance. 3M recommends at every lamp
change or at least once a year that air vents, lamp module and lamp compartment be cleaned with a vacuum.
2. Vacuum the lamp cavity to remove all dislodged dust.
ENGLISH
3. Vacuum the lamp inlet and exhaust vents to clear any dust or dirt build up.
Important Note: Do not touch the glass reflector or the bulb. If oils from your skin transfer to the glass it will
weaken the heat resistant properties of the reflector/bulb and significantly shorten the lamp’s life.
5. Bulb Envelope - This is the shape of the bulb inside the lamp module.
Visible Indications of an Expired Lamp
The following five visible indicators help you recognize an expired lamp.
2
2
3
ENGLISH
4
3
5
1. Cloudy Bulb – A cloudy bulb may reduce the image brightness. The lamp will appear to have white or black
deposits on the inside of the bulb. These deposits are a sign of normal wear and tear. Replace the lamp if the
brightness is inadequate.
2. Disconnected or broken wires – If the lamp wires are broken, the lamp will not ignite. Replace the lamp if the
lamp wires are broken
3. Deformed Bulb – A deformed bulb will reduce the image brightness. A bulb is deformed when the bulb
envelope expands into an irregular, round shape. Replace the bulb if it becomes deformed.
4. Debris on Bulb End – If the lamp will not ignite, the bulb seal may have broken. When bulb seal is broken,
debris from the bulb will form at the break. Most of the times, this is at the bulb tip.
5. Broken Bulb – The lamp will not ignite if it is broken. Sometimes you will hear an abnormal sound when
you try to start the projector. Please refer to the Safety Instructions for more information about handling
broken bulbs.
The Standby button on the I/O
module does not light while the
projector is powered on.

not cross power cables
or other communication
cables. If it does, reroute
the cables so that they
do not cross. If the
communication cable
between the projector and
