Abstract
A probe assembly for use with an ink reservoir level sensing apparatus comprises an insulating support frame formed of an electrically insulating material. The insulating support frame includes a lower portion to be positioned in a lower portion of an ink reservoir and an upper portion configured to be positioned in an upper portion of the ink reservoir. The insulating support frame has a lower probe and an upper probe each partially encapsulated by the electrically insulating material of the insulating support frame such that the lower and upper probes are physically and electrically isolated from each other, and positioned with respect to each other such that at least a portion of the lower probe is positioned in the lower portion of the frame, and the upper probe is positioned above the lower probe in the support frame extending to the upper portion of the frame. An outer probe is attached to the insulating support frame using attachment features that are formed integrally with the insulating support frame. The outer probe is positioned on the insulating support frame extending from the lower portion of the frame to the upper portion of the insulating support frame.
