Thanks everyone for all the suggestions. The problem turn out to be a faulty HV unit. The previous tech allowed the machine to be down for two weeks before he said something. So I didnt take any chances, I replaced both HV's ( a pain in the butt to get to them!)

The IU developer had been sucked out! The toner collect box was unusally heavy (full of Developer) I will replace them tommorrow.
