Abstract

See full text

The invention provides a method and system for determining fluid levels in an inkjet printer. A non-contact sensor array is provided external to the container in which the levels are to be determined and each sensor in the array is sequentially switched into a sensing circuit until a change in capacitance is noted. The sensing circuit is preferably a frequency oscillation circuit whose frequency is defined by circuit capacitance.
