Patent ID: 8065913

Claim:
A probe assembly for use with an ink reservoir level sensing apparatus, the probe assembly comprising: an insulating support frame formed of an electrically insulating material, the insulating support frame having 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 including a lower probe and an upper probe, the lower probe and the upper probe being partially encapsulated by the electrically insulating material of the insulating support frame to physically and electrically isolate the lower probe from the upper probe, and a first portion of the insulating support frame being molded about a portion of the upper probe to position the portion of the upper probe within the insulating support frame and a second portion of the insulating support frame being molded about a portion of the lower probe to position the portion of the lower probe within the insulating support frame; and an outer probe attached to the insulating support frame using attachment features that are formed integrally with the insulating support frame, the outer probe being positioned on the insulating support frame extending from the lower portion of the insulating support frame to the upper portion of the insulating support frame.
