摘要： A modular inkjet printhead assembly including a plurality of printhead modules mounted on alternating sides of a central rail assembly. The rail assembly includes a beam and a rod attached to a side of the beam. The printhead modules include a jetting module having an array of nozzles, a first alignment tab having a first alignment datum and a second alignment datum, a second alignment tab having a third alignment datum and a fourth alignment datum, a rotational alignment feature including a fifth alignment datum, and a cross-track alignment feature including a sixth alignment datum. Portions of the alignment tabs of the jetting module are adapted to fit within corresponding notches in the beam. A jetting module clamping mechanism and a jetting module cross-track force mechanism apply forces to the jetting module that causes each alignment datum to engage with corresponding alignment features on the rail assembly.

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： An inkjet recording apparatus includes an ink particle generation unit that makes a pressurized ink injected from a nozzle into particles, a charging unit that electrically charges the ink particle of those subjected to particulation, which corresponds to a dot to be printed, a polarizing unit that polarizes the electrically charged ink particle in a polarizing electric field, a collection unit that allows a gutter to collect the ink particle corresponding to the dot that is not printed, and a character forming unit that forms a character as a dot matrix on a printing object. A phase detection charging signal is applied to the ink particle that is not used for printing when forming the dot matrix character so as to detect an optimum charging timing in a process of forming the dot matrix character.

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 ink-jet recording apparatus has a print head 13 incorporating: a nozzle 20, which vibrates ink at a constant cycle, jets out the ink, and atomizes the ink; an electrification electrode 26, which electrify an ink particle 19; and deflection electrodes 27b, which deflect the electrified ink particle in a main scanning direction. The print head 13 carries out printing by causing the ink particle to fly to a printing workpiece W conveyed by a conveyer 15. Flying time of the ink particle in a printing distance La between the printing workpiece W and the print head 13 is calculated, timing of an electrification signal supplied to the electrification electrode 26 is controlled in accordance with the flying time, and a printing position to the printing workpiece W is set. Thus, printing can be carried out at a predetermined position to the printing workpiece W, and printing quality can be enhanced.
