摘要： A liquid ejection system ejects a liquid jet through a nozzle. A drop formation device modulates the jet causing portions to break off into drop pairs, including first and second drops, separated on average by a drop pair period, and modulates the jet to cause portions to break off into larger third drops separated on average by the same period. A charging device includes a varying electrical potential source providing a waveform including first and second distinct voltage states and a period equal to the drop formation period. The charging device and the formation device are synchronized to produce first, second, and third charge to mass ratios on the first, second, and third drops, respectively. A deflection device causes the first, second, and third drops to travel along first, second, and third paths, respectively. The first and third charge to mass ratios and paths are substantially the same.

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： An apparatus and method of ejecting liquid drops includes modulating a liquid jet to cause it to break off into drop clusters, including first and second drops traveling along a path, separated on average by a drop cluster period. An input image data independent charging waveform of a charging device includes a period that is equal to the cluster period and first and second voltage states having opposing polarities. The charging device produces first and second charge states on the first and second drops, respectively, of each cluster. The first and second drops are deflected away from the path toward first and second catchers, respectively. Relative velocity of drops of a selected drop cluster is modulated in response to input print data causing the drops to form a merged drop traveling along the path having a third charge state that prevents it from being deflected to either catcher.

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. The drop forming device is actuatable to produce a modulation in the liquid jet to selectively cause portions of the liquid jet to break off into one or more pairs of drops traveling along a path. Each drop pair is separated on average by a drop pair period. Each drop pair includes a first drop and a second drop. The drop formation device is also actuatable to produce a modulation in the liquid jet to selectively cause portions of the liquid jet to break of into one or more third drops traveling along the path separated on average by the same drop pair period. The third drop is larger than the first drop and the 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 period of formation of the drop pairs or the third drops, the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device and the drop formation device are synchronized to produce a first charge to mass ratio on the first drop of the drop pair, a second charge to mass ratio on the second drop of the drop pair, and a third charge to mass ratio on the third drop. The third charge to mass ratio is substantially the same as the first charge to mass ratio. A deflection device causes the first drop of the drop pair having the first charge to mass ratio to travel along a first path, and causes the second drop of the drop pair having the second charge to mass ratio to travel along a second path, and causes the third drop having a third charge to mass ratio to travel along a third path. The third path is substantially the same as the first path.
