Abstract: In an ink jet system printer of the charge amplitude controlling type, wherein a printing head is transported in a horizontal direction and vertical deflection is achieved by a pair of high voltage deflection plates, it is required to transport the printing head at a fixed velocity in the printing process. More particularly, in order to execute intermittent printing by repetition of the transporting and stopping of the printing head in response to intermittent input signals, it is necessary that printing is restricted during the time required for increasing the velocity of the printing head to a desired level and then permitted after that time. The present invention provides a system wherein the generation of printing start signals is delayed by a predetermined period following the application of input signals, and also a system wherein printing start signals are generated when the actual velocity of the head has been sensed as reaching the desired velocity.

Abstract: An ink jet system printer of the charge amplitude controlling type wherein a predetermined phase relationship is established between separation of ink drops from a nozzle to a record receiving member and application of charging signals to a charging electrode, through detection of the amplitude of charge carried on ink drops contributable to phase determination. Charging signals of one polarity containing intelligence signals are supplied to the charging electrode to charge ink drops contributable to printing, whereas phase detecting signals of the opposite polarity to that of the charging signals are supplied to the charging electrode for the purpose of charging ink drops contributable to phase determination. Both of the charging signals and the phase detecting signals are mixed in a mixer circuit arrangement of a simple construction which consists of a pair of switches, before both signals are supplied to the charging electrode.
