ABSTRACT:
Ink reservoirs containing binary elements facilitate discrete sensing of ink level within the reservoir. The binary elements are adapted to provide an electrical path in response to an applied electrical signal if the element is immersed in the ink. The binary elements are further adapted to present an open circuit in response to the same applied electrical signal if the element is above a level of the ink. The binary elements may be single-use or multi-use elements, i.e., their state change may be irreversible or reversible, respectively. Based on the presence or absence of an electrical path, the ink level can be deemed to be at or above a level of the binary element, or below the level of the binary element, respectively.
