Paper Stuck In Printer

[Cloverjo]

I have an HP C7280 printer. A piece of paper got jammed, I pulled most of it out through the removable back. There is a bit stuck in there that I can't see or access. The printer is refusing to work with it in there. The only accessible screws are of a 5 pointed star type that I've never seen before. Even if I got the screws out, would I be able to take the printer apart to get the stuck bit of paper?
Thank you.

Does anything here help?

Thank you, Buenchico. There was a bit of paper wedged in the right hand side which I wouldn’t have seen without that video.
