Title: Electrical interconnect for replaceable ink containers

Abstract: The present invention is a replaceable marking media container for use in an off-axis printing system. The printing system includes a printer portion responsive to electrical signals from the replaceable ink container for controlling printer parameters. The replaceable marking media container includes a plurality of electrical contacts with each of the plurality of electrical contacts electrically connected with a memory element. The memory element contains information for controlling printing system parameters. Included in the replaceable ink container a housing having an outer surface facing outwardly and an inner surface. The inner surface defines a cavity within the housing. The plurality of electrical contacts are attached within the cavity, so disposed and arranged, to engage corresponding electrical contacts associated with the printing system. The corresponding electrical contacts associated with the printing system are positioned within the cavity of the marking media container with proper positioning of the marking media container within the off-axis printing system. The use of these electrical contacts allow information to be exchanged between the memory element and the printer.
