6. Fasten the adjustment screw (reference 1 Image 11-9) which you released in step 1. Use a 5.5 mm nut driver.
When you are familiar with this adjustment procedure you can optimize the focus position by first
rotate the Integration Rod until you clearly see the sloped edges on the screen and then focusing
these edges as sharp as possible. Then rotate the Integration Rod back until the projected light
beam matches the projected outline of the DMD's. This way of focusing has to be done quickly.
Otherwise, the sealing between the DMD's and the prism will be damaged
10.12 Adjusting the Light Pipe lens No3 (zoom
lens)
Purpose of the Light Pipe zoom lens
The Light Pipe zoom lens is located inside the Light Pipe between the Integration Rod and the Fold Mirror. The
light spot upon the DMDs can be reduced or enlarged with the Light Pipe zoom lens to fit with the outline of the
DMDs.
CAUTION: Only qualified and authorized personnel may perform this procedure.
To adjust the Light Pipe focus lens the left cover of the projector and the side cover plate of the Light
Processor compartment have to be removed.
Required tools
Nut driver 5.5 mm
How to adjust the Light Pipe zoom lens?
1. Loosen the adjustment screw of the Light Pipe zoom lens (reference 5 Image 10-18) a few turns. Use a 5.5
mm nut driver. Do not remove the adjustment screw.
2. Start up the projector but do not activate the light source yet.
Caution: Projecting a light spot which is larger then the DMD outline for more then 10 seconds may
cause irreversible damage to the Sealed Light Processor. Therefor, it is important to maximum dim the
light output and adjust the light spot as quickly as possible.
3. Set up the projector to display a full white internal pattern with a maximum contrast and a maximum
dimming . Do not activate the light source yet. Make sure that you have a 5.5 mm nut driver within reach for
the next steps.
4. Activate the light source and zoom the projector lens in or out until the projected image is focused.
Note: Dialog windows must be displayed sharp instead of blurry. This is independent of the focus of
the light beam.
5. Adjust the position of the Light Pipe zoom lens by moving the adjustment screw (reference 5) UP or DOWN
into a position where the light spot (reference 2) matches the projected outline (reference 3) of the DMDs upon
