Maintenance action Remarks
1 Check 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.
Replace damaged filters
immediately.
See procedures “Vacuum
cleaning of the dust filters”, page
145, and “Washing and drying the
dust filters”, page 145.
To speed-up drying, allow the
filter(s) to dry at 50°C max in a
well ventilated room.
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.
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.
3 Check the porthole (both sides) for dust. Clean the porthole in case dust is
clearly visible upon the surface.
Use an optical cloth.
4 Check the good working condition of the external safety interlock
system (if installed).
