The reference head holder (51R) is rotated about the reference nozzle, and the other head holders (51G and 51B) are also rotated simultaneously. The head holders (51G and 51B) are formed to be movable parallel to a sub scanning direction, irrespective of the rotation angles thereof.Type: GrantFiled: December 15, 2005Date of Patent: July 7, 2009Assignee: Brother Kogyo Kabushiki KaishaInventor: Makoto Goto

Publication number: 20090021557Abstract: A modular encoder has been developed that can be mounted to a motor shaft without requiring time consuming alignment or special tools. The encoder includes a base having an annular opening, the base including a plurality of resilient arms surrounding the annular opening with each arm having a terminal end that extends into the annular opening, and a hub having a horizontal flange with a top and a bottom surface and a generally vertical wall extending from the bottom surface of the horizontal flange, the wall is configured to fit within the annular opening of the base and is circumscribed with a groove for receiving the terminal ends of the resilient arms to secure the hub to the base and enable rotation of the hub within the annular opening of the base as the terminal ends of the resilient arms slide within the groove.Type: ApplicationFiled: July 19, 2007Publication date: January 22, 2009Applicant: Xerox CorporationInventor: David Scott Allaway

Patent number: 7377617Abstract: A printer comprises an arm mounted on a pivot member. The arm has a first portion adapted to move along an arcuate path. A drive motor rotates the arm about the pivot member. An electromagnetic radiation emitter mounted on the first portion is adapted to emit pulses onto an electromagnetic radiation-sensitive medium.Type: GrantFiled: October 12, 2004Date of Patent: May 27, 2008Inventors: Leo C. Clarke, Douglas C. Snell, Makarand P. Gore

Patent number: 7134736Abstract: A drive assembly for a printer includes an endless loop drive path and guide structure that allows a printhead to operate in either reciprocal or endless loop modes in which the printed traverse both a liner and an arcuate portion of the drive path. This provides a printer architecture in which a printhead may be endlessly driven at a constant speed in one direction to provide multiple print swaths separated spatially. This eliminates the need for deceleration/acceleration changes required in reciprocal printer architectures and is capable of increased throughput by defining arcuate turnaround zones that can be traversed by the printhead faster than the time it takes to slow, stop and reverse a conventional reciprocal printhead assembly. This robust printer architecture also allows flexibility in use of multiple printheads with simultaneous printing, simultaneous both side printing, and duplex capabilities.Type: GrantFiled: January 8, 2004Date of Patent: November 14, 2006Assignee: Fuji Xerox Co., Ltd.Inventors: Eric A. Merz, Brian S. Hilton

Patent number: 7021732Abstract: A method includes ejecting ink from a first set of one or more nozzles to form a first image pattern at least partially within an image field. The method likewise includes ejecting ink from a second set of one or more nozzles to form a second image pattern at least partially within the image field. The first image pattern and second image pattern form a composite pattern within the image field. Then, an optical detector obtains a measurement of an optical characteristic of the image field. The measurement may be compared with a reference optical characteristic for the composite pattern within the image field.Type: GrantFiled: November 12, 2003Date of Patent: April 4, 2006Assignee: Xerox CorporationInventor: Jeffrey J. Folkins

Patent number: 6869155Abstract: A method and apparatus for masking a workpiece with a layer of ink from an inkjet head is disclosed. The masking prevents exposure of select regions of a photosensitive workpiece. The apparatus includes a workpiece pre-aligner for movably supporting and aligning the workpiece. The inkjet head is arranged to be in operable communication with the photosensitive layer of the workpiece when positioned on the pre-aligner and is adapted for providing a select mask of opaque ink on a photosensitive layer. Where the photosensitive layer is a negative tone photoresist, upon exposure the portion of the photosensitive layer that is not exposed because of the presence of the mask is removed upon developing. In this manner, select regions of the workpiece can be kept clear of photoresist or otherwise patterned with indicia such as alphanumeric symbols or barcodes.Type: GrantFiled: August 6, 2001Date of Patent: March 22, 2005Assignee: Ultratech, Inc.Inventor: Borislav Zlatanov
