An ink loader for a phase change ink imaging device includes an automated access control system that enables ink stick insertion based on user initiated ink load requests with reference to the operating state of the imaging device.
8075128 Image transfer element with balanced constant force load December 13, 2011
An image transfer mechanism includes a pressure element and a lever system. The lever system has a load attachment point with a range of position that depends on the thickness of a print medium positioned between the imaging element and the pressure element. A load mechanism includes
8075118 Segmented ink stick December 13, 2011
A method facilitates insertion of a segmented ink stick into an ink feed system of a phase change ink jet printer. The method includes bending of a flexible strand between ink stick segments during insertion of the ink stick segments and then straightening the flexible strand to orient t
7753509 Segmented ink stick July 13, 2010
An ink stick for a phase change ink jet printer is provided. The ink stick includes a first ink stick body segment having a proximal portion and a distal portion, a second ink stick body segment having a proximal portion and a distal portion, and one or more flexible strand portions. The
7497566 Image transfer element with balanced constant load force March 3, 2009
An image transfer mechanism includes a pressure element and a lever system. The lever system has a load attachment point with a range of position that depends on the thickness of a print medium positioned between the imaging element and the pressure element. A load mechanism includes
7438402 Rolling ink stick October 21, 2008
An ink stick for use in a phase change ink jet printer is provided wherein the ink jet printer has an ink feed channel having a feed direction leading to a melt plate. The ink stick comprises an ink stick body having an external surface and an axis of rotation. The ink stick body is
6783026 Systems and methods providing bi-directional passage of an object via an articulated member August 31, 2004
An articulated flag body member permitting bi-directional passage of an object. The articulated flag body member has a flag body pivotably connected to a flag foot. As rotation of the flag foot occurs in one direction, the flag body rotates by engagement of a recess of the flag foot
6293545 Stripper blade assembly September 25, 2001
A stripper blade assembly for an ink jet offset printer has a thin blade fixedly mounted on a top surface of a blade holder. The blade holder includes at a trailing edge flexible eyelet portions that extend downwards to snap over protuberances on mechanical connectors overmolded onto a
6015205 Print head restraint mechanism January 18, 2000
A print head restraint mechanism for limiting movement of a print head during transport of the printing apparatus is provided. The restraint mechanism includes a moveable pin that selectively engages the print head. An engaging mechanism moves the pin into and out of engagement with the
5904350 Apparatus and method for deskewing media in a printer May 18, 1999
A method and apparatus for deskewing a sheet of media traveling through a paper path in a printer is provided. A buckle is formed in the sheet of media by over-driving the sheet into stationary deskew rollers that form a deskew nip downstream. A deskewing bias element includes a pluralit
5820275 Printer multi-function drive train apparatus and method October 13, 1998
A process motor (82) provides bidirectional motive force to a printer (50) drive train (80) that selectively engages with multiple self-homing printing functions. A print head (52) is tiltable to a maintenance position and a transfer roller (64) is loadable against a transfer drum (5
5619240 Printer media path sensing apparatus April 8, 1997
A media sensing system monitors the movement of media along the media pathway (76) as a sheet of printing medium (56) is transported through the printer 50. The media sensing system permits a hand fed sheet of printing medium (56) to be detected by a sensor (302) and signal to be sent to
5442387 Apparatus for supplying phase change ink to an ink jet printer August 15, 1995
A triggerable ink transfer system that simultaneously transfers ink from a plurality of ink preload chambers to corresponding load chambers and ink reservoirs is disclosed. The delivery system permits an untrained operator to safely load ink without inadvertently interchanging different
5223860 Apparatus for supplying phase change ink to an ink jet printer June 29, 1993
A triggerable ink transfer system that simultaneously transfers ink from a plurality of ink preload chambers to corresponding load chambers and ink reservoirs is disclosed. The delivery system permits an untrained operator to safely load ink without inadvertently interchanging different
5202622 Adapter and test fixture for an integrated circuit device package April 13, 1993
A test fixture for a high pin count surface mounted IC device has a test head assembly connected to an adapter having electrically conductive elements that couple the output of the IC device to test points on the test head assembly. The test points are coupled to conductive pads on the
