Try cleaning the bias contacts on the back of the developer unit and the rear frame of the copier, then regrease with conductive grease.

Lower the metal guide on the trans/sep corona
Hope this helps

This model uses to have problems with separation between drum and developer roller, there are two rollers in both sides of the magnetic roller. Try to replace them. These rollers have to be new with each drum replaced.
Good luck.
