Abstract
Systems and methods for detection of the directivity of trajectories of charged drops issuing from a jet are disclosed. According to one aspect, an electrostatic sensor is disclosed which includes a flat functional surface. The electrostatic sensor is configured to function in a non-differential manner and has a geometric shape and arrangement that are substantially aligned relative to a nominal trajectory of drops. A trajectory of drops can be followed at the same time in a plane parallel to the flat surface of the sensor and in a plane perpendicular to the flat surface of the sensor. As a result, it can be verified whether a drop is present or remains in a predefined monitoring zone. According to another aspect, a method of controlling trajectories of drops in a print head having a continuous deflected jet, and a method of monitoring the effective recovery by the gutter of drops not intended for printing are disclose.
