As northerntech said. I would try pulling out the pretransfer corona assembly. And run the copier without it in the machine. If the voltage comes back than you know you have a bad pretransfer. If i doesn't it could be a bad transfer seperation corona unit. Try this first and see if this helps.

I hope you tried with another corona assy. If transfer corona works than you have charge corona problem. Separation corona doesn't affect on blank copies.
Take out high voltage board and clean contact pins that supplies high voltage to corona. I think there is six of them. If that doesn't work probably the board is dead. I know we take this boards for some electronic service that fixses it.
Post result...
