Maintenance action
1
Check both dust filters of the projector for dust and grease.
Grease on the filter can build up after several months in an environment
contaminated with greasy air. Note that areas where popcorn is consumed are
subject to greasy air.
•
If the filters are contaminated with dust than cleaning the filters with a
vacuum cleaner should be sufficient.
•
In case the filters feel greasy than the filters must be washed.
Take into account that the time needed to dry the dust filters may be 24 hours or
more. For that, it's recommended to have a second set of dust filters which can
be used while cleaning the first set.
2
Check the surface of the lens output side for dust. (it is not needed to remove
the lens from the projector). Only clean if necessary.
3
Check the porthole (both sides) for dust.

Remarks
Replace damaged filters immediately.
See procedures "Remove and clean the
front dust filter", page 139,"Remove and
clean both bottom dust filters", page
140.
To speed-up drying, allow the filter(s)
to dry at 50°C max in a well ventilated
room.
Clean the lens output side in case dust
is clearly visible upon the surface.
Note: if the lens was removed from
the projector, a manual "Lens Home
& Return" action must be executed
to calibrate the position of the lens in
relation to the Lens Holder. This way
the references of the existing 'lens files'
remain valid. See user guide of the
Communicator software.
Clean the porthole in case dust is clearly
visible upon the surface. Use an optical
cloth.
