6.7 Realignment of the lamp in its reflector
Each xenon bulb lamp installation requires a realignment of the lamp in its reflector for optimal performance
of the xenon bulb lamp in the DP-1500 projector. 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. Remov e the cover of the lam p c ompa rtment to gain ac cess to the X -, Y -, and Z-axis adjus tment thumbs crews of the lamp.
2. Switch on the projector and start up the lam p.
3. Go via the Communicator touch panel to the menu “Installation” > “Lamp” > “Light output”.
4. Set the “Light output mode”innormal 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.
