Anyone know how to clean a Screenplay 4800?

I got dust every where in it. They are putting up a subdivision next door and all the dust from the trucks the past 3 years has built up.

I even blew out the bulb every month as per the Infocus directions.

Thanks,
CM

You might want to check out X1 FAQ (thehttp://members.shaw.ca/technut/x1faq/). The X1 and the 4800 are twins. I owned an X1 for 3 years. Great machine. I never used compressed air in it. I remember it being warned against quite often. Dust blobs are the result. The optics are not sealed on the X1 (4800).

Good luck.
