13. HDF Light Processor
13.8 Adjusting the Fold Mirror
Purpose of the Fold Mirror
The fold mirror is folding up the light path of the projector to make the projector more compact. The fold mirror is located at the left
side of the light pipe and re
fl
ects the light, which entrance the light pipe via the integration rod, upon the prism of the light processor.
The position of the light spot upon the DMD’s can be adjusted with the fold mirror.

AUTION
:
Normally the Fold Mirror should never be readjusted in the
fi
eld. In case a readjustment is required
follow the instructions in this chapter precisely. Only quali
fi
ed technicians who have experience with adjust-
ing the Fold Mirror may adjust the Fold Mirror. A misaligned Fold Mirror may cause irreversible damage to
other parts of the projector!
To access all three adjustment screws of the Fold Mirror the left side cover has to be removed from the pro-
jector. Both top adjustment screws are easy accessible but to reach the bottom screw, the Fold Mirror cover
plate together with the light sensor unit has be removed from the Light Pipe. This procedure assumes that
the left side cover is already removed from the projector.
In most cases the Fold Mirror can be correctly aligned by turning the upper two adjustment screws of the Fold
Mirror. These upper two screws can be accessed with a nut driver through the holes of the Fold Mirror cover.
So, the removal of the Fold Mirror cover is unnecessary.
How to adjust the Fold Mirror
1. Disconnect the wire unit from the Light Sensor Module.
2. Remove the Fold Mirror cover and the Light Sensor Module as a whole from the Light Pipe as illustrated. Remove both indicated
Torx screw (reference 1).

Caution:
Projecting a misaligned light spot for more then 10 seconds may cause irreversible damage to the Light Processor.
Therefore, it is important to maximum dim the light output and adjust the light spot as quickly as possible.
4. Turn the adjustment screws A, B or C in or out until the light spot (5) matches with the outline of the DMDs (4). Use a 5,5 mm open
end wrench. The illustration below shows the movements of the light spot (5) upon the screen (6) for each adjustment screw.
