The projector uses two identical 100W UHP (Ultra High Pressure) lamps and can be
operated with both lamps ON (Dual Lamp Operation mode) or with one lamp ON
(Single Lamp Operation mode). One of the projector's main features is that it
automatically switches modes, if possible, to maintain continual operation. It is really
important to be aware of your projector's status to effectively maintain continuous
operation. Another feature of the projector is that you can replace an expired or
faulty lamp without having to power the projector down or disrupt your current
presentation – this is called "hot-swap".
For more information on the lamp operation modes and other options in the Lamp
menu, see 3.11 The Lamp Menu.
When should lamps be replaced?
Typically, aging lamps decrease slightly in their intensity. You can check the number
of hours each lamp has been in use by checking Lamp Hours in individual lamp
submenus. From the Lamp menu, you can also set a Lamp Limit (max 20,000
hours) and enable the projector to send a lamp replacement, warning message when
it's powered on.
At anytime during operation, you can check the status of a lamp by checking the
Lamp Strike Status in individual lamp submenus – More, Lamp 1 or More, Lamp 2.
You will see one of six states: "Good", "Cooling Fan #3 Failed", "Cooling Fan #5
Failed, "Interlock Tripped", "Failed to Strike" and "Turned Off Unexpectedly". A
status of "failed to strike" or "turned off unexpectedly" indicates a failure that
requires further investigation and may or may not be directly related to the lamp.
If you have ruled out the cause being an aged lamp or another component in the
projector, it may indicate that your lamp has prematurely burned out or failed for
some other reason (check status LEDs and/or error codes through RS-232, if
possible). Burned out lamps or lamps that have failed due to some characteristic flaw
should be replaced, as soon as possible.
In general, monitor the performance of your projector and replace lamps as needed.
