Patent number: 6367917Abstract: E1 A CIJ printhead includes a droplet deflector electrode having one or more windows formed therein, and a phase or velocity detector electrode disposed within the window. A method of forming the electrodes by plating multiple conductive and dielectric layers is also disclosed.Type: GrantFiled: June 21, 1999Date of Patent: April 9, 2002Assignee: Domino Printing Sciences PLCInventor: Jerzy Marcin Zaba

Patent number: 6309058Abstract: A method of printing uses a multi-nozzle ink jet print head having a pressure modulator for causing streams of ink emitted from the nozzles to be broken up into individual droplets. The nozzles are divided into a plurality of groups of nozzles, and groups of charge electrodes correspond, each group of charge electrodes having a respective charge controller. In the method a modulation waveform is generated to operate the pressure modulator to cause droplets to be generated in each stream. The charge controllers are operated to supply a charge signal waveform to charge electrodes and charge droplets in the streams. The phase relationship of the charge signal waveform is adjusted relative to the modulation waveform.Type: GrantFiled: August 20, 1999Date of Patent: October 30, 2001Inventors: Ammar Lecheheb, Jerzy Marcin Zaba, Ray Rijing Yu

Patent number: 6206509Abstract: We provide a method of printing using a multi-nozzle ink jet print head having a pressure modulator for causing streams of ink emitted from the nozzles to be broken up into individual droplets. The nozzles are divided into a plurality of groups of nozzles, and groups of charge electrodes correspond, each group of charge electrodes having a respective charge controller. In the method a modulation waveform is generated to operate the pressure modulator to cause droplets to be generated in each stream. Independently for each group of charge electrodes, the respective charge controller is operated to supply a charge signal waveform to each charge electrode in turn, the phase of the charge signal waveform relative to the modulation waveform is adjusted between 0 and 360 degrees in a number of steps, and the optimum phase relationship to achieve proper charging for each droplet stream is determined in turn.Type: GrantFiled: August 20, 1999Date of Patent: March 27, 2001Assignee: Domino Printing Sciences, PLCInventors: Ammar Lecheheb, Jerzy Marcin Zaba

Patent number: 6203150Abstract: A liquid collection apparatus comprises a liquid collecting device and liquid conduit for transferring liquid from the liquid collection device. Porous liquid absorption device is positioned between the liquid collection device and the liquid conduit. Pump device pumps liquid from the liquid conduit, the pump device generating a pressure in the conduit that is sufficient to draw liquid through the liquid collection device but is insufficient to draw a gas/liquid surface through the liquid absorption device.Type: GrantFiled: April 8, 1999Date of Patent: March 20, 2001Assignee: Domino Printing Sciences PlcInventors: Jerzy Marcin Zaba, William Anthony Denne, Richard Frank Mitchell

Patent number: 5943077Abstract: A print head for a continuous ink jet printer has a nozzle through which ink is emitted and broken up into droplets under the action of a piezoelectric oscillator. A charge electrode applies charge to selected droplets and a deflection electrode deflects the path of the charged droplets to cause printing on a substrate. A gutter collects droplets which are not required for printing. A charge electrode, together with one of the deflection electrodes is movable in a direction transverse to the path of the droplets selectively under the action of pressurized ink fed from an ink supply. Similarly, the gutter is movable in the same way by another actuator.Type: GrantFiled: April 6, 1998Date of Patent: August 24, 1999Assignee: Domino Printing Sciences PLCInventors: Jerzy Marcin Zaba, Richard Marsden
