Basic Image Alignment

NOTES: 1) Assumes projector is fully assembled and powered up in its final location. 2) Projector in
standard non-motorized lens mount configuration. 3) For information on how to adjust the projector's
displayed image using the motorized lens mount refer to Appendix A: Intelligent Lens System.
This procedure ensures that the image reflected from the DMDs is parallel to and well-centered with the lens
and screen. This initial optical alignment is the foundation for optimizing images on the screen and must be
completed before final boresight adjustments.
Ensure the CP2220 is properly positioned relative to the screen before you begin. Refer to
the Projector, on page

2.8.1 Basic Optical Alignment Procedure

1. Display a good test pattern appropriate for analyzing image focus and geometry, such as the "framing" test
pattern showing the crosshair centered across the image.
2. Course focus: Perform a quick preliminary focus and (if available) zoom adjustment with the primary lens
only (Refer to
across the image is not required at this point.
3. Center the image in the lens: Holding a piece of paper at the lens surface, adjust the offsets as necessary
until the image is centered within the lens perimeter. A full white field works best for this.
4. Re-check side-to-side leveling: With the framing test pattern on screen, re-check projector leveling (refer
to STEP 3 - Adjust Tilt/Leveling, on page

Offset and Boresight Alignment

NOTES: 1) Projector must be fully assembled
and powered up in its final location. 2) Install the
auxiliary lens, if it will be used at the site. 3) A
5mm Allen key is required for Boresight
alignment.
To ensure proper offset for your site and
consistent focus in all areas of the screen, a
primary lens must be installed and its lens mount
precisely adjusted in relation to internal optics as
described below. If desired, an auxiliary lens can
then be added to widen images for "scope"
cinema displays.
