Abstract
Information relating to the impact position on a catcher face of a deflected ink jet is used to adjust various parameters of an ink jet printing system, such as the charge voltage, the time between orifice plate stimulation and drop charging, etc., or to check the occurrence of malfunctions such as crooked jets, misregistration between the charge plate and the jets, etc. According to the invention, means integral with the catcher cooperate with the ink flowing on the catcher face to vary an electrical property at said catcher face as a function of the portion of that face which is ink wetted. In one embodiment the jet impact position is derived from an electrical resistance measurement. In another embodiment this position is derived from a capacitance measurement.
