Disclosed is a xerographic printing apparatus and print cartridge including a deformable electrically conductive ring. According to an exemplary embodiment, a xerographic image rendering print cartridge includes a drive shaft, a photoreceptor drum and a deformable electrically conductive ring operatively associated with electrically connecting an inside surface of the photoreceptor drum to the drive shaft to provide a grounding electrical path.

A power supply apparatus receives a voltage from power rails on a circuit board. The power supply apparatus comprises a frame and arms connected to the frame. Each of the arms comprises a contact end. The frame positions the contact end of each of the arms to contact the power rails of the circuit board. The contact end is biased towards the power rails to maintain the contact end in contact with the power rails. The contact end comprises a curved planar surface having a first edge and a second edge that terminates at an end edge. The first edge and the second edge follow a curved line, while the end edge follows a straight line. The contact end comprises a non-linear slot extending from the end edge along the curved planar surface and is positioned equally between the first edge and the second edge.

Systems and methods of a pay-for-use pricing plan for consumables associated with a machine. The systems and methods include a machine that can detect a use of a consumable by a consumer. The use can be an installation of the consumable in the machine or an actual use of the consumable in the machine. The machine can detect a charge associated with the use of the consumable. Further, the machine can prompt the consumer for a payment and receive the payment from the consumer. In embodiments, the consumer can have an updatable account associated with the consumable usage. The machine can send an indication of the payment or updated account information to a supplier of the consumable.
