Upon powering up the projector with a
newly-installed/replaced lamp, adjust lamp
position to help ensure optimized operation
as well as peak brightness at the screen—
you do not need an image displayed yet.
Once you have done this LampLOC
adjustment, the lamp will be well centered
and distanced correctly from the remainder
of the illumination system.
At the TPC, automatically optimize lamp
position by pressing the
the Advanced: Lamp menu. Watch the
gauge on this menu. After 2-3 minutes,
with the projector using an internal light sensor, the best lamp position will be
established and the
DO AUTO
output is optimized.
NOTE: Lamp must be on and the shutter open during LampLOC
however the projector does not need to be displaying an image.
Determining Screen Brightness (fL)
In order for the TPC to display screen brightness in footlamberts (fL), you must
measure screen brightness at both extremes of lamp power (minimum and maximum)
for a given lamp type, and record these two readings in the TPC Admin: Lamp menu
available to installers. These measurements establish a range (stored in memory)
from which the TPC can interpolate all other lamp power settings, converting them to
approximate footlamberts for display in the menus. Repeat the calibration if you ever
switch to a different lamp type/size.
For more information about menus and footlamberts, see Section 3.
This image alignment procedure assumes projector is fully assembled and powered
up in its final locations.
This initial optical alignment procedure is the foundation for optimizing your
displays, ensuring that images reflected from the DMDs are parallel to and well-
centered with both the lens and screen. It should be complete before adjusting lens
boresight.
NOTE: Before you begin:
 Properly position the projector relative to the screen (refer back to Figure 2.9.)
Basic Optical Alignment Procedure
Display a good test pattern appropriate for analyzing image focus and geometry,

worry about consistency across the image at this point, just center focus.
