Anybody know what a DRU sliding contact is? Where is this? What is this? Do I need to order a new pin array?

Look inside the drum, motor side, the two sliding contacts you see are what is being called. Just reach in with the printer idleing and clean the carbon disk with ISO or something that doesn't leave a residue. If that doesn't clear it then monitor the connector, to ground, above the intake with your meter. At idle the voltage should be ablow 20vdc and running it has to be below 39vdc. If it's high you're probably looking at a drum.

| Hi, 07501 is the discharge pin array, it could just be arcing at the endblocks or it is a power supply failure. |

07501 also calls out the sliding contact. Probably just needs a complete PM.
