Abstract
An ink drop detector includes a sensing target which is imparted with an electrical stimulus when struck by at least one ink drop burst which has been ejected from an ink drop generator. The detector also includes electronics coupled to the sensing target which characterize the electrical stimulus in terms of a mathematical phase. Methods for analyzing ink ejected from an ink drop generator, and a method for optimizing ink drop generator firing frequency are also provided.
