    Re: Cleaning projectors

    Is this in addition to just cleaning the filter with a can of compressed air?

    If so I've no idea, that's all I do

    Re: Cleaning projectors

    Can you actually do this? For example, how high up are the projectors? Do you need to use a ladder? Have you been on the appropriate H&S courses for working up ladders/at heights. Does the school insurance cover you for doing so?

    We have the propper step ladders for the job. I would take them down to work on. as for filter cleaning, I do this once a month, may be twice a month in the wood workshops and science labs.

    I'm allowed to use step ladders, but have been advised to use when the school day is over.

    Re: Cleaning projectors

    There was a post on here a while ago about solving the "projector yellowing" issue on certain makes and models of projectors - it included instructions for dismantling projectors and I've mirrored the procedure on my wiki.

    In the past, we have found that cleaning the internal lenses one at a time with some lens cloths works admirably

    36 projectors in cages all padlocked and then security locked in place?
    Ours are padlocked on to the bracket, then the cage is locked, we have a set of keys for every single projector and bracket.
    And promethean say to clean the projectors at least once a month. Yeah lets do the math:

    Get in class when its empty
    Get up to projector
    Open cage
    Open padlock
    Disconnect all cables
    Remove projector
    Clean air filters
    Replace projector
    Replace cables
    Replace padlock
    Lock up
    Switch on
    Re-calibrate with whiteboard (for staff who don't know how) X36

    Re: Cleaning projectors

    Don't! We've had em two years and not cleaned more than about 5 in that time :P
    Even then it was only the science and food tech ones due to a lot of smoke/chemicals etc in the air.

    I was just saying theoretically that was the process we'd have to take.

    cheers for that craig. I'm feeling a little nervous about doing this, but I do have one or 2 in the school the need to be done. Will print the wiki off and let you all know how i managed.

    Re: Cleaning projectors

    Geoff, I do most of the AV stuff anyway. Setting up stuff for drama exams and productions, video recording and editing, photography, photo editing. Just done a bit on audio software too.
    The drama teachers saw our deputy head to say they want me employed as AV as well as IT but obviously if they can get away with it on the cheap, they will :?
