Centering:
Confirm that all shadowy edges cast by the integrator are projected OFF the screen, with the
white field fully visible and centered between shadows. If necessary, use the fold mirror adjustment screws
to precisely direct the white field between all edge shadows. Centering signifies that the rectangle of light
passed from the integrator completely illuminates the DMDs. (

Adjusting Lamp Position (LampLOC
™
)
LampLOC
™
is a required adjustment after servicing many of the projector’s optical components. The
adjustment can be performed Automatically or Manually from the
Advanced Setup: LampLOC Setup
window. Perform LampLOC
™
to adjust the lamp position for optimal lamp performance and peak brightness at
the screen for the life of the lamp. Once LampLOC
™
adjustment is complete, the lamp will be well-centered
and distanced correctly from the remainder of the illumination system.
Before adjusting LampLOC
™
, ensure the following criteria are met:
• The lamp is installed with the anode yoke in the correct location for the lamp type.
• The lamp extension nut is used with CDXL-30SD lamps only.
NOTE
:
DO NOT use the lamp extension nut
with other lamp types, otherwise it can lead to extremely dim light output.
• The lamp must be ON and the douser (shutter) is OPEN during adjustment. A 10-minute warm-up is recom-
mended.
• Display a white test pattern. This is recommended to allow you to view LampLOC
™
progress on-screen.
