Abstract
A corotron cleaning assembly includes a self-seating, spring-loaded locating pin drivingly connected to a drive unit that is used to drive a wire cleaning head that is located within a CRU. This assembly allows for easy separation of the drive unit from the cleaner when the CRU that contains the wire is replaced. The bullet shaped pin rides on a worm drive and when the pin is driven into the cleaner head, the bullet hits an inclined ramp and is biased downward until such a point that the pin hits a recessed receptacle. Once the pin is in the receptacle, the pin is capable of driving the wire cleaning head. When the cleaning head is removed, the act of removal separates the pin from the receptacle.
