Abstract: Method of recording with a stream of marking fluid drops in which a predetermined plurality of successively formed drops in streams each has the same electrical charge induced therein so that, subsequently subjected to an electrostatic field, all drops of one common by charged plurality with impact a record member at approximately the same spot. Drop charges are induced therein by asynchronously applied charging signal levels, each of which has a duration functioning the drop formation frequency and equal to at least two drop periods.

Abstract: A base voltage of one polarity and signal voltages of the opposite polarity are applied to the charging electrode of an ink jet printer in selected sequences, so that two or more oppositely charged drops merge in flight to produce larger drops, thus controlling not only the placing of the drops on a document but the density of the printing also.
Abstract translation: 一个极性的基极电压和相反极性的信号电压以选定的顺序施加到喷墨打印机的充电电极，使得两个或更多相反电荷的液滴在飞行中合并以产生较大的液滴，从而不仅控制放置 的液滴在文件上，但印刷的密度也是。

Abstract: A device for use in an ink jet printing system which comprises a vapor chamber and means for moving said chamber to enclose the jet nozzles during shut-down period to prevent ink from drying at the nozzle. A sharp edge wall is provided to keep the charging electrodes and deflection plates free from ink spraying at pressure shut-off and means are provided for mounting the charging electrodes for movement out of the jet path prior to shutdown of the printer to prevent ink spraying thereon at pressure shut-off.
Abstract translation: 一种用于喷墨打印系统的装置，其包括蒸气室和用于在关闭期间移动所述室以包围喷嘴的装置，以防止油墨在喷嘴处干燥。 提供锋利的边缘壁以在压力切断时保持充电电极和偏转板不受油墨喷射，并且提供用于在打印机关闭之前安装用于移动到喷射路径之外的充电电极的装置，以防止在其上喷墨 在压力关闭。

Abstract: Method of recording with a stream of marking fluid drops in which a predetermined plurality of successively formed drops in a stream each have the same electrical charge induced therein so that, when subsequently subjected to an electrostatic field, all drops of one commonly charged plurality will impact a record member at approximately the same spot. Drop charges are induced therein by asynchronously applied charging signal levels, each having a duration which is a function of the drop formation frequency and equal to at least two drop periods.
