Dukane Starfire Portable/ProfessionalOverhead Projectors Projector Lamp Questions & Answers
Check Air Flow sign keeps popping up and I have no
Hi,
With most projectors there is a foam air filter behind a grill that is
the opening to the cooling channels. A fan ensures air flow to cool the
lamp, etc. This filter prevents dust from gumming up the works (and
depending on design) may prevent dust getting into the optics. As the
filter gets dirty it gradually cuts off the air and at some point a
protective circuit kicks in and turns off the lamp.
If the projector is on you will feel a stream of hot air coming out of
the exit vent. Projectors vary in terms of amount of air flow, so its
difficult to define what is normal for a specific model. However, you
can simply hold a hand in front of the vent and see if there is air flow
(It will be hot air so, careful). If there is a "good" stream of air
things are fine, but if only a very light flow is felt the filter may be
dirty.
If the filter has not been cleaned or replaced recently make sure the
projector is turned off and cooled down then take off the inlet cover
and remove the filter. Clean or replace per the instructions for the
projector (and periodically as defined .. but taking into account the
operating conditions). Once cleaned turn on the projector and feel the
"normal" air current for future reference.
Heat is one of the major causes of projector failure, so make sure
cooling vents (inlet and outlet) are not obstructed and filters are kept
clean.
Let me know, if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
Just bought a Dukane 4003 but it didn't come with
Don't know if you solved it on your own or not but I had the same problem. You have to remove the cord from the doors at the bottom so the mirror can come all the way down. It also allows the legs to come out. Hope it's not to late.
