Abstract: An ink level sensing system that exhibits good sensitivity is described herein. The system includes a first probe having a first active surface, a second probe having a second active surface facing the first active surface, a memory in which data indicative of a conductivity curve and command instructions are stored, and a processor configured to execute the command instructions to associate a level of fluid in a reservoir with a first signal indicative of the electrical coupling between the first active surface and the second active surface with reference to the data indicative of a conductivity curve.
