Check or replace Dmax sensor. Also check or replace drum potential sensor. I say this assuming all PM related items have been properly addressed. These machines do not tolerate old corona wires, drums and grids.

You also want to check continuity of the mag roller to the bias tab in the rear of the developer unit. The bearing at the rear of the mag roller loses continuity between the inner race and outer race of the bearing. Its easier to just replace the developer unit at that point.
