摘要： The optimum excitation frequency for forming successive ink drops in an ink jet printer is determined by forming a sequence of ink drops at a plurality of different drop-formation frequencies and phases thereof and integrating a detected current representative of the value of the charge on the ink drops as a function of time for each the plural frequencies and phases thereof to create a corresponding plurality of waveforms. The frequency of the optimum waveform, which minimizes the undesired formation of satellite ink drops and undesired drop dispersion, is then selected for use during the next print mode. The optimum waveform is characterized by a single maxima and minima separated in phase by a value no greater than a predetermined maximum value.

摘要： An ink jet recording apparatus of the continuous jet type wherein the position of an ink jet jetting axis or nozzle axis can be detected readily with a simplified construction. The ink jet recording apparatus comprises test signal generating means which generates a controlling signal which varies continuously. Switch means selectively couples one of recording signal generating means and the test signal generating means to a controlling electrode of charging means provided for charging an ink drop. An electrically isolated conductive drop catcher catches an ink drop which has passed by separating means for forming an ink jet, and current detecting means detects electric charge carried to the conductive drop catcher by charged ink drops as an electric current. Relative position detecting means measures a relative positional relationship between an ink jet flying axis and the separating means from a controlling voltage outputted from the test signal generating means and an output of the current detecting means.

摘要： An ink jet recording apparatus which effects non-impact recording by the application of a jet of ink to a recording medium while the amount of ink to be jetted towards the recording medium is controlled to render it proportional to the recording velocity. For this purpose, the ink jet recording apparatus is provided with a feed-back loop system through which an electrical signal indicative of the pressure acting on the ink within an ink tank is fed back to a comparator to control operation of a compressed air source from which the pressure is applied to compensate for reduction in static pressure of the ink within the ink tank resulting from consumption of the ink. For maintaining the amount of the ink jetted proportional to the recording velocity, various arrangements are disclosed.

摘要： An ink jet recording apparatus with ink drop registration control adjusts the timing of the ink drop or drops that form each pixel to compensate for time-of-flight differences that are a function of the number of ink drops that form a pixel and as a function of the ink drops that constitute one or more immediately preceding pixels. A pixel buffer stores successive pixel data in a first-in first-out (FIFO) manner so that the timing of the ink drop for a current pixel can be adjusted, in part, as a function of the number of ink drops of at least one next successive pixel.

摘要： A continuous ink jet recording apparatus which can record an image always with an appropriate density on any of various record media. A vibrating element driver drives a piezoelectric vibrating element in response to a disintegrating frequency signal from an oscillator to disintegrate a jet of ink from a nozzle. A multiplier multiplies picture element data of a line buffer by a density coefficient, and a pulse width modulator converts the picture element data from the multiplier into a charging controlling signal of the pulse width which increases in proportion to the number of ink drops per picture element. The charging controlling signal is applied via a high voltage switch to a controlling electrode, by which the in drops are charged in accordance with the charging controlling signal. A deflecting electrode deflects the charged ink drops. A frequency divider and a frequency converter frequency divides the disintegrating frequency signal by a gradation number and the density coefficient to obtain a picture element recording frequency signal, and a drum motor controlling circuit drives a drum motor to rotate a rotary drum at a speed in accordance with the picture element recording frequency signal.
