Nope sorry WRONG on several levels. You don't want to go blowing air around from the outside hoping it will land in the right place. This is like sweeping dust around a room hoping it will not blow back to the center. You need to remove the dust. You will also have spots on the panels and optics that need to be wiped.. the fuzzy sticks work great for this . You don't want to work on it while the case is open because you could easily short out a cable or a connector. Also there will be dust behind the front lens that is usually pretty easy to clean with a handkerchief wrapped around a strip from a Business card. - BohannaQuote:

I do think the key is to have the projector running, projecting black, and focussed on the dust blobs while cleaning. This is the way it worked on Sanyo projectors that had ports built into the case so you could blow air on the panels without opening it up and while it was running. Some blobs were blown out on the first few tries, but others were stubborn and took a lot of effort. It's much easier when you can see it all happening in real time.
I will probably try it on my Epson 5030 eventually, but the one dust blob I have now is not that bad so I'm going to wait a while.
BTW, when I cleaned my old Sanyo Z5, focussing on the dust blobs showed not just the 2 or 3 that I thought there were, but hundreds of other smaller ones that weren't visible individually but were scattering light and increasing the overall black level. After blowing out the dust the black level improved noticably.

Yes indeed, use an air blower like the one shown above.
Do not use compressed air as it can 'spot' the insides and you'll be far worse off.
