Hp C3180 Prints Half A Sheet, Anyone Can Help Me?

Hi Everybody!

I'm Mark and I'm facing a trouble with my Multifunctional HP C 3180. It scans, copies but doesn't print, and when occurs a "miracle", it prints two sheets and third sheet, prints a half.
Does anyone can help me?
Thanks!!

PS - Multifunctional is new. I bought one month ago...

What windows are you using? What service pack level? Have you been to HP to download new drivers?
