Patent number: 6796630Abstract: Droplet deposition apparatus includes a base and a printhead adjustably mounted on the base and positionable relative to a datum on the base such that a swath or print produced by the printhead is in a predetermined position relative to the datum, the base being locatable on a printer using the datum. This can enable the printer to be easily replaced without any loss of alignment of the produced print swath relative to the carriage or body of the printer.Type: GrantFiled: December 6, 2002Date of Patent: September 28, 2004Assignee: Xaar Technology LimitedInventors: Robert M. Ison, Werner Zapka, Jerzy M. Zaba

Patent number: 6725543Abstract: A component for a drop-on-demand piezoelectric printhead is formed from a block of piezoelectric material and a substrate. The block of piezoelectric material has grooves formed in its lower surface and is attached to the substrate using an adhesive that is applied in sufficient quantity such that adhesive enters the grooves cut into the piezoelectric material. Upper grooves are sawn into the piezoelectric material through to the glue-filled lower channels in order to form ejection channels, the walls of which are separated from one another by means of a glue fillet.Type: GrantFiled: January 31, 2002Date of Patent: April 27, 2004Assignee: Xaar Technology LimitedInventors: Veena K. Sarojiniamma, Salhadin Omer, Angus Condie, Jerzy M. Zaba

Patent number: 5087924Abstract: A printhead for a continuous ink jet printer has a body with a circular recess in an end face thereof. A circular piezoelectric transducer is disposed in the recess so as to provide a short ink chamber adjacent the face of the body and the piezoelectric transducer is arranged to expand and contract in the direction of its axis when an excitation voltage is applied to it. An ink feed channel connects with the recess for feeding ink to the ink chamber and a nozzle plate is detachably mounted on the end face of the body to eject ink under pressure when the piezoelectric transducer is actuated.Type: GrantFiled: January 23, 1991Date of Patent: February 11, 1992Assignee: Domino Printing Sciences PLCInventors: Jerzy M. Zaba, Howard J. Manning
