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 printhead includes a droplet-forming heater operable in a first state to form droplets from a fluid stream having a first volume traveling along a path direction and in a second state to form droplets from the fluid stream having a second volume traveling along the path direction. A droplet deflector system is positioned relative to the droplet-forming heater, which applies a force to the droplets traveling along the path direction, whereby the droplets having the first volume diverge from the path direction by a greater extent than do the droplets having the second volume. A droplet-steering heater is adapted to selectively asymmetrically apply heat to the stream such that the path direction is changed.

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 pair period. The charging device produces first and second charge states on first and second drops of the drop pair, respectively. A drop velocity modulation device varies a relative velocity of first and second drops of selected drop pairs causing first and second drops of selected drop pairs to form combined drops having a third charge state. A deflection device causes the first, second, and combined drops to travel along different paths.
