Hi,
The ghosting is caused by the fuser assembly. The main user roller has a Teflon coating that keep the toner from sticking, when the coating wears off you start getting the ghost printing like you are having. You can get replacement fusers online from many sources, just do a Google search for P2055DN Fuser. They are user replaceable, only requiring a Phillips screwdriver to replace.
