Appl. No.:

8/228471

Ross R. Allen - Belmont CA

Assignee:

Hewlett-Packard Company - Palo Alto CA

International Classification:

B41J 201

US Classification:

347 50

Abstract:

A plurality of inkjet printhead elements are arranged to form a pagewide printhead array. The elements are secured to a flexible interconnect to allow for communication between the individual elements and a printer controller. The elements are arranged in the array so that one or more nozzles overlap nozzles of the two adjacent elements. The printer controller specifies the desired drivers of the heater elements to be actuated in commands sent to the first element in the array over the flexible interconnect. The printer elements monitor the interconnect to determine whether the command specifies a heater element under their control. The printer elements then actuate the specified heater element to cause an ink droplet to be ejected from a nozzle corresponding to the selected heater element.

International Classification:

G01D 1516
B41J 304

US Classification:

346140R

Abstract:

A dot-matrix printer is provided with different types of printheads which are interchangeably attachable to the printer carriage. The heads are provided with individual codes which are read by the printer control system and used to reconfigure its control function to suit the control requirements of the identified head. Such a system may include a microprocessor responsive to individual sets of instructions or programs providing new and different processing capabilities for printing control in response to the insertion of a new printhead.

International Classification:

US Classification:

347 14

Abstract:

A page-wide-array ("PWA") inkjet printer includes a printer element defining a printhead with thousands of nozzles spanning a pagewidth. A media sheet travels along a media path adjacent to the printhead to receive character or graphic markings. Typically, a media sheet accelerates from rest to a constant velocity. To optimize print speed nozzle timing is controlled to respond to changes in media velocity. Printing occurs while the media is accelerating and while traveling at a constant velocity. A sensor positioned in fixed relation to a PWA printer element detects the media's actual velocity. Actual velocity is fed back to a printhead controller which compares actual velocity to a rated constant velocity. If actual velocity is slower than the rated velocity, then nozzle timing is adjusted to be slower than a rated timing. If actual velocity is faster than rated velocity, then nozzle timing is adjusted to be faster than the rated timing.

International Classification:

B05C 5/02

Abstract:

A non-contact deposition system comprises a jetting assembly including at least one micro-valve. The micro-valve includes an orifice plate defining an orifice therethrough. An actuating beam disposed in a spaced relationship to the orifice plate. The actuating beam including a base portion and a cantilevered portion extending from the base portion towards the orifice and is movable between a closed position and an open position. A sealing structure comprising a sealing member is disposed at the overlapping portion of the cantilevered portion. A fluid manifold is coupled to the micro-valve and defines a fluid reservoir containing a pressurized fluid. When the actuating beam is in the closed position, the cantilevered portion is positioned such that the sealing structure seals the orifice so as to close the micro-valve, and in the open position, the fluid is dispensed from the orifice towards a substrate and deposited thereon.
