摘要： Ink jet printing apparatus having a cleaning system whereby ink is supported proximate the droplet orifices, the charge plate and/or the operative catcher surface and ultrasonic cleaning vibrations are imposed on the supported ink mass. Such cleaning can be implemented with ink cross-flowing through the print head cavity and/or in cooperation with a varying pressure differential across the charge plate, which cause ink to oscillate inwardly/outwardly within the orifices.

摘要： An ink jet printer for depositing drops of ink at a plurality of print positions on a moving print receiving medium includes a print head producing at least one jet drop stream directed toward the medium and a charge electrode positioned adjacent the point of drop formation of the jet drop stream. A charging means repetitively applies a high guard drop potential to the charge electrode during formation of at least every second drop for charging of the drops to a guard charge level. During formation of the remainder of the drops, either one of a number of relatively low print potentials or a substantially larger catch potential is applied to the charge electrode. Drops formed during application of a print potential to the electrode may carry a charge of either electrical polarity due the drop-to-drop cross talk from previously formed guard drops. Drops carrying a guard charge level and drops carrying a catch charge level are deflected by an electric field to a catcher, and drops carrying any of the print charge levels are deflected by the field to associated print positions on the medium.

摘要： An ink-jet printer for recording information by jetting ink droplets on a recording medium has a plurality of ink-jet nozzles arranged so that ink droplets projected therefrom combine in flight at a space between the nozzles and the recording medium. The amplitude and the pulse width of driving signals used to deflect piezoelectric elements which contract to expel the ink droplets from the nozzles are appropriately varied to vary the momentum of the individual ink droplets projected from each nozzle so that the combined ink droplets will have a velocity and direction representative of the information to be recorded.

摘要： An ink jet method and apparatus including circuitry for controlling lateral deflection of an ink column before drops are formed. A deflection mechanism used to deflect the column comprises two electrode portions spaced on opposed sides of the column. By control of the voltages applied to the electrode portions the angle of ink column deflection is made proportional to a control voltage applied to the portions. This proportionality facilitates control over column scanning to insure proper ink drop placement on the ink jet recording medium.

摘要： In an electrostatic type ink-jet printer of the type leaving "guard drops" between charged drops, an electronic circuit is provided which generates charge-enabling signals in response to which guard drops are charged. When a sync signal is generated which synchronizes the rotation of a rotary drum with a print signal, one of the charge-enabling signals which is timed to charge an ink drop causes this ink drop to be charged. As compared with the prior art, ink dot misplacement due to the out-of-synchronization which in turn is due to the variations in rotation of the rotary drum can be more finely corrected. In addition, ink dot misplacement can be more precisely corrected by controlling the charge on an ink drop by pulses which have divided periods of that of the sync signals and which are synchronized with the sync signals.

摘要： A circuit, for applying a potential to a charge electrode in a multiple jet ink jet printer to compensate for the cross talk charging effect of adjacent electrodes on the jet filament, includes a means for applying a catch potential or a print potential to the electrode. Means are provided for altering the print potential when one of two adjacent electrodes is supplied with a catch potential and means are provided for altering the print potential when both of the adjacent electrodes are supplied with a catch potential. The print potential is reduced by an amount sufficient to reduce the cross talk field from adjacent electrodes in the region of the jet to the same potential level as the jet filament. A transistor current source applies a large current to the charge electrode during catch operations such that the stray capacitance associated with the electrode is rapidly charged and the electrode is brought to the catch potential rapidly.
