I would attempt to clean off any crud or "smoothness" with isopropyl alcohol.
I've gotten various rollers and belts working again by a simple cleaning.  Sometimes those belts can pick up material or have some sort of chemical breakdown on the surface and become slick and not have the friction they once had.
