4.7 Realignment of the lamp in its reflector
Each xenon lamp installation requires a realignment of the lamp in its reflector for optimal
performance of the xenon lamp. Furthermore, it is recommended to realign the lamp after the first
run time of 100 and 200 hours. Especially the Z-axis of the lamp.
WARNING: This procedure may only be performed by qualified technical service personnel.
How to realign the lamp in its reflector?
1. Remove the cover of the lamp compartment to gain access to the X-, Y-, and Z-axis adjustment
thumbscrews of the lamp.
2. Some lamp houses may have lock nuts on the X and Y adjustment screws which are locked. Before
starting the adjustment, fully turn these lock nuts against the thumbscrew.

3. Switch on the projector and start up the lamp.
4. Go via the Communicator touch panel to the menu “Installation” > “Lamp” > “Light output”.
5. Set the “Light output mode” in normal mode and the “Lamp Dimming” on maximum (255).
Note: This window on the Communicator touch panel shows in the upper left corner the
measured value of the built-in light sensor of the projector.
