I feel a little silly saying this, but I can't figure out how to remove the lens cap from this used Mitsubishi XD490U projector that I got today. It's not like the cap on a DSLR lens. No spring loaded tabs on the sides to press and pull the cap off or any such thing. When I hold on to the cap and turn I can see the focus ring of the projector turning. I didn't want to try too hard, for fear of messing something up.

The cap looks like something that should come off by pulling it but I can't get it to. Is there a trick to doing this?
