Basic Image Alignment

NOTE: Assumes projector is fully assembled and powered up in its final location.
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. To save the focus, offset and zoom settings to the channel, you
must make the adjustments using the motorized lens mount adjustment features from the Lens Control menu
in the CDP or via one of two menus from the Web UI - the ILS screen launched from the Main menu or the
Channel: Lens menu. Using the knobs on the lens mount to adjust these positions does not save the settings to
the channel. They are designed for temporary use and will therefore be lost once the channel changes. Ensure
the CP2000-ZX is properly positioned relative to the screen before you begin.

2.7.1 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: Do a quick preliminary focus and (if available) zoom adjustment with the primary lens only
(Refer to Section 3.7 Working with the
point, just center focus.
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 pattern on screen, double-check projector leveling (refer
to Section 2.4 Adjusting Tilt and

Offset and Boresight Alignment

To ensure proper offset for your site and consistently good 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. Warning! 1) If the
Motorized Auxiliary Lens Mount (MALM) is present, ensure to
move the MALM to the OUT position before performing any lens
calibrate or reset functions on the Motorized Primary Lens
Mount to prevent collision between the projection lens and the
MALM. 2) Hazardous moving parts. Keep fingers and other
body parts away. NOTES: 1) Projector must be fully assembled
and powered up in its final location. 2) Keep clear of rotating
parts. Remotely operated motors may start to spin without
warning. 3) Avoid long hair, jewelry, and loose clothing
exposure to the knobs during manual adjustment. 4) In case of
emergency, unplug the line cord to immediately halt movement of the lens mount.
