Publication number: 20030025763Abstract: An on-axis ink reservoir that is pivotally secured to the carriage of an inkjet printer thereby defining an engaged position, in which the ink reservoir is in fluid communication with a printhead secured to the carriage, and an open position, in which the ink reservoir pivots away from the printhead to allow easy access to the printhead without the need to remove the ink reservoir from the carriage. Preferably, the ink reservoir is detachably secured to an ink-reservoir mounting portion, the printhead is detachably secured to a printhead mounting-portion, and these two mounting portions are pivotally secured together. More preferably, the ink-reservoir mounting portion includes a plurality of ink reservoirs, and the printhead mounting-portion includes a plurality of printheads. A latching mechanism is provided to operably secure the two mounting portions together in the engaged position.Type: ApplicationFiled: July 31, 2001Publication date: February 6, 2003Inventors: Scott D. Sturgeon, Jeffrey T. Hendricks, David C. Johnson, Charles R. Steinmetz, Daniel W. Petersen

Patent number: 6488368Abstract: Disclosed is a manifold providing fluid connections between a plurality of carriage-mounted ink reservoirs and multiple carriage-mounted printheads, the manifold having ink conduits allowing the spacing, ordering, or number of printheads to differ from the spacing, ordering, or number of ink reservoirs. The manifold also serves to mechanically isolate the printheads from the ink reservoirs, such that replacement of one or more reservoir does not adversely affect the alignment of the printheads. The manifold allows simple optimization of a printing system to a particular application by replacing the manifold with one of a different configuration.Type: GrantFiled: January 26, 2001Date of Patent: December 3, 2002Assignee: Hewlett-Packard CompanyInventors: Daniel W. Petersen, Charles R. Steinmetz, Scott D. Sturgeon, Jeffrey T. Hendricks

Patent number: 6488369Abstract: The present disclosure relates to a replaceable ink reservoir for installation into a printing system that has a moveable carriage for repositioning a printing portion relative to print media. The replaceable ink reservoir includes an ink reservoir that does not have an integral printing portion. Also included is an electrical storage device for storing information. The installation of the ink reservoir into the moveable carriage establishes both fluid communication between the ink reservoir and the moveable carriage and establishes electrical continuity between the electrical storage device and the moveable carriage.Type: GrantFiled: January 31, 2000Date of Patent: December 3, 2002Assignee: Hewlett-Packard CompanyInventors: Charles R Steinmetz, Scott D Sturgeon, David C Johnson, Jeffrey T Hendricks

Publication number: 20020175977Abstract: The present disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station for receiving the replaceable ink container. The replaceable ink container includes a handle extending from a trailing end of the ink container for grasping the ink container for insertion into the receiving station. Also included is a latch for securing the replaceable ink container to the receiving station. The latch has an extended position for engaging the receiving station for securing the ink container to the receiving station and a retracted position. The latch is so disposed and arranged on the ink container to be urged from the extended position to the retracted position as the handle is grasped.Type: ApplicationFiled: May 16, 2002Publication date: November 28, 2002Inventors: Lisa M.

Patent number: 6375315Abstract: A replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station that is mounted to a scanning carriage. The receiving station has a keyed portion being indicative of a replaceable ink container parameter of a plurality of replaceable ink container parameters. The replaceable ink container includes a reservoir portion having a leading end and a trailing end relative to an insertion direction into the receiving station. Also included is a keying portion disposed on the trailing end and configured to be complementary to the keyed portion thereby allowing the replaceable ink container to be fully inserted into the receiving station.Type: GrantFiled: April 11, 2000Date of Patent: April 23, 2002Assignee: Hewlett-Packard CompanyInventors: Charles R. Steinmetz, Scott D. Sturgeon, David C. Johnson, Jeffrey T. Hendricks

Patent number: 6350073Abstract: A Z-fold print media handling system for printing banners and the like uses an inkjet printing mechanism without a tractor-feed. A series of stuttering stopping and starting steps generates varying static and dynamic frictional forces to separate the first sheet of a Z-fold stack from the remainder of the stack. Both conventional cut-sheet media and Z-fold media are fed using the same printing mechanism, which pulls the media toward a printzone through frictional engagement with a first surface of the media To prevent printhead crashes and smearing the image near the perforations joining the Z-fold sheets, the printhead to media spacing is increased for Z-fold media over the standard spacing used for cut-sheet media. A cam feature is incorporated into the media drive clutch disk to determine whether an operator has set a selector lever for cut-sheet or Z-fold printhead to media spacing.Type: GrantFiled: July 12, 2000Date of Patent: February 26, 2002Assignee: Hewlett-Packard CompanyInventors: Thomas E McCue, Jr., Gary Hays, John C Santon, Raymond C Sherman, William Watts, Jeffrey T Hendricks, Ivan F.

Patent number: 5745133Abstract: A dual pivoting wiper system cleans the nozzle face plate of an inkjet printhead, particularly one that dispenses a pigment based ink. An inkjet printing mechanism has a printhead service station including a sled that moves from a rest position to a wiping position. The wiping system includes a support arm with proximate and distal ends, with the proximate end pivoted to the sled and the distal end pivotally supporting an upright wiper blade. The arm is spring-biased to push the wiper blade into engagement with the printhead. During wiping, the printhead is engaged by wiper blade and the blade remains relatively upright. Any spacing variations between the printhead and the sled are accommodated by spring flexure, and any lack of parallelism of the printhead from a nominal plane is primarily accommodated by pivoting of the blade at the distal end of the support arm.Type: GrantFiled: October 31, 1995Date of Patent: April 28, 1998Assignee: Hewlett-Packard CompanyInventors: Jeffrey T.
