Aligning the image

Only perform image alignment after the projector is fully assembled and powered up in its final
location.
Basic image alignment ensures the image reflected from the DMDs is parallel 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. Before beginning, make sure the projector
is properly positioned in relation to the screen.
1. Make sure the projector is positioned in the throw distance range for the particular lens.
2. Display a test pattern.
3. Do a quick preliminary focus and (if available) zoom adjustment with the primary lens.
Do not worry about consistency across the image at this point, just center focus. It is good
practice to have zoom adjustment and focus adjustment in the center of its range.
4. Holding a piece of paper at the lens surface, adjust offsets as necessary until the image is
centered within the lens perimeter. A full black field works best for this.
5. If the projector is mounted off center to the screen axis, offset the lens as much as required.
Aim the projector over slightly towards the center of the screen, but use caution when doing
so, as too much tilt causes excessive keystone distortion.
6. With a framing pattern on screen, double-check projector leveling so the top edge of the image
is parallel to the top edge of the screen.

Once the lens removal has begun the safety retention features of the lens are defeated.
To re-engage the safety lock mechanism, the lens must be removed and re-inserted, or
fully rotated clockwise until a click is heard.
Packaging tape is required to ensure safe shipment of the projection lens to restrain the
zoom ring from rotating during shipping.
