    摘要: A group timing delay device is provided to shift the timing of drop formation waveforms supplied to drop formation devices of nozzles of one of first and second groups so that print drops formed from nozzles of the first and second groups are not aligned relative to each other along a nozzle array direction. A charging device includes a common charge electrode associated with liquid jets formed from the nozzles of the first and second group and a source of varying electrical potential between the charge electrode and liquid jets. The source of varying electrical potential provides a charging waveform that is independent of print and non-print drop patterns. The charging device is synchronized with the drop formation device and the group timing delay device to produce a print drop charge state on print drops and a non-print drop charge state on non-print drops.

    摘要: A method of ejecting liquid drops includes providing liquid under pressure sufficient to eject a liquid jet through a nozzle of a liquid chamber. The liquid jet is modulated to cause portions of the liquid jet to break off into a series of drop pairs traveling along a path using a drop formation device. Each drop pair is separated in time on average by the drop pair period. Each drop pair includes a first drop and a second drop. A charging device is provided that includes a charge electrode associated with the liquid jet and a source of varying electrical potential between the charge electrode and the liquid jet. The source of varying electrical potential provides a waveform that includes a period that is equal to the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device is synchronized with the drop formation device to produce a first charge state on the first drop and to produce a second charge state on the second drop. A relative velocity of a first drop and a second drop of a selected drop pair is varied using a drop velocity modulation device to control whether the first drop and the second drop of the selected drop pair combine with each other to form a combined drop. The combined drop has a third charge state. A deflection device is used to cause the first drop having the first charge state to travel along a first path, to cause the second drop having the second charge state to travel along a second path, and to cause the combined drop having the third charge state to travel along a third path.

    摘要: A continuous liquid ejection system includes a liquid chamber in fluidic communication with a nozzle. The liquid chamber contains liquid under pressure sufficient to eject a liquid jet through the nozzle. A drop formation device is associated with the liquid jet and is actuatable to produce a modulation in the liquid jet that cause portions of the liquid jet to break off into a series of drop pairs traveling along a path. Each drop pair is separated in time on average by a drop pair period. Each drop pair includes a first drop and a second drop. A charging device includes a charge electrode associated with the liquid jet and a source of varying electrical potential between the charge electrode and the liquid jet. The source of varying electrical potential provides a waveform that includes a period that is equal to the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device is synchronized with the drop formation device to produce a first charge state on the first drop and to produce a second charge state on the second drop. A drop velocity modulation device varies a relative velocity of a first drop and a second drop of a selected drop pair to control whether the first drop and the second drop of the selected drop pair combine with each other to form a combined drop. The combined drop has a third charge state. A deflection device causes the first drop having the first charge state to travel along a first path, causes the second drop having the second charge state to travel along a second path, and causes the combined drop having the third charge state to travel along a third path.
