4 Adjust the Image
This section provides information and procedures for adjusting the projector image.
4.1

Maximize Light Output

To ensure optimal operation and peak screen brightness, use LampLOC™ to adjust the lamp position
whenever you install a new lamp. When you complete the LampLOC adjustment, the lamp is centered and is
the correct distance from the illumination system. Before running LampLOC, verify that:
• The anode yoke is in the correct position for the lamp type.
• The lamp extension nut is installed when using a CDXL-30SD lamp. Remove the nut if you are not using a
CDXL-30SD lamp.
• The lamp is on and the douser is open.
1. On the Touch Pad Controller, tap the Test Patterns icon.
2. Tap the Full Screen White test pattern.
3. Tap Menu > Advanced Setup > LampLOC™ Setup.
4. Tap Do Auto.
4.2

Calibrate Screen Brightness (fL)

1. On the Touch Pad Controller, tap Menu > Administrator Setup > Foot Lamberts Calibration.
2. Complete the Foot Lamberts Calibration wizard.
4.3

Basic Image Alignment

This procedure ensures that the image reflected from the digital micromirror device (DMD) is parallel and
centered with the lens and screen. This procedure must be completed before you complete a boresight
adjustment.
1. Verify the projector is properly positioned relative to the screen. See 2.3 Position the Projector.
2. Display a test pattern that you can use to analyze image focus and geometry. The framing test pattern
works well for this.
3. Perform a preliminary focus and (if available) a zoom adjustment with the primary lens. Focus the center
of the image first. See
4. Hold a piece of paper at the lens surface and adjust the offsets until the image is centered within the lens
perimeter.
5. With the framing test pattern on screen, re-check projector leveling so the top edge of the image is parallel
to the top edge of the screen.
