摘要： An ink jet apparatus electrifies ink (2) in a nozzle (4), and ejects the ink (2) from an ink ejecting hole (4b) onto a printing medium (8) by a first electric field generated between the nozzle (4) and the printing medium (8). The ink jet apparatus includes an ink catching device which includes an ink catching portion (14) provided at a position adjacent to the nozzle (4) and catches an ejected substance ejected from the nozzle (4). In addition, between the nozzle (4) and the ink catching portion (14), the ink jet apparatus applies a voltage for generating a second electric field which (i) causes the ejected substance, which is formed from the ink (2) or the ink (2) whose viscosity is changed, to be ejected from the nozzle (4) and (ii) causes the ink catching portion to attract the ejected substance. With this, in a configuration which utilizes an electrostatic force to eject fluid, it is possible to promptly remove a clogging of an ejection head at any position, and it is also possible to realize less initial ejection fluctuation and improve the reliability of ejection.

摘要： An inkjet printhead includes two groups of interleaved nozzles. First and second sets of drop-formation waveforms are associated with the groups of nozzles to selectively cause portions of a liquid jet to break off into drops. A timing delay device time-shifts the second-group waveforms relative to those associated with the first-group waveforms. A charging-electrode waveform having portions with first and second potentials is provided to a charging electrode. The waveform energies of the second-group waveforms is larger than the waveform energies of the corresponding first-group waveforms so that printing drops break off from the liquid jets while the charging-electrode is at the first potential, and non-printing drops break off from the liquid jets while the charging-electrode is at the second potential.

摘要： A continuous ink jet printer projects a stream of evenly spaced ink drops toward a substrate and controls placement of the ink drops on the substrate by selectively charging the individual ink drops and passing the charged ink drops through an electric field to control placement of said charged ink drops on a substrate. The printer may be used to print either single or multiple lines of print in a single stroke. A stroke consists of a single column from all lines and can have adjacent drops printed in alternating lines to reduce drop interaction. Each line of print in the stroke having N virtual print positions, at least some of which are being divided into pairs of adjacent positions. Each pair of adjacent positions has a first print position and a second print position. The printer includes a controller having a plurality of first and second look-up tables, each of which is associated with a different one of said pairs of adjacent print positions. Each of the look-up tables contains a plurality of charge values which correspond to the charge to be applied to a print drop in one of the first or second print positions, respectively, as a function of the charges of each of a predetermined number of drops that are proximate to the print drop in the drop stream. The adjacent drops may include a predetermined number of history drops that precede the print drop in the stream and a predetermined number of future drops that follow the print drop in the stream. The controller determines the charge to be applied to drops and produces a control signal responsive thereto by (1) retrieving a charge value from one of the first lookup tables if the drop is to be printed in one of the first print positions, or (2) retrieving a charge value from one of the second look-up tables if the drop is to be printed in one of the second print drop positions. A charging tunnel receives the control signal from the controller and charges the drops to the determined charges in response thereto.
