Patent number: 8387973Abstract: According to one example, there is provided a controller readable medium on which are stored controller readable instructions. The instructions are such that, when executed by a controller, perform the steps of commencing the printing of a print job on a media sheet, determining when about half of the media sheet ejected out of a printer media output is at the level of a stacker unit, activating a first array of fans to retain a portion of the ejected media sheet, completing the print job, and activating a second array of fans to blow the trailing edge of the ejected media sheet over the stacker unit.Type: GrantFiled: February 29, 2012Date of Patent: March 5, 2013Assignee: Hewlett-Packard Development Company, L.P.Inventors: David Chanclón Fernández, Ricardo Sanchis Estruch, Joan Sanjuán Mercadal, Emilio López Matos, Xavier Alonso Becerro, Ignacio De Olazábal Zugasti, Gianni Cessel

Patent number: 6158849Abstract: A technique for aligning a carriage holding a pen in a printing machine including a carriage axis assembly having a motor drive system for moving the carriage along a carriage axis, a carriage position sensor, and a refill station disposed along the axis.Type: GrantFiled: February 27, 1998Date of Patent: December 12, 2000Assignee: Hewlett Packard CompanyInventors: Joaquim Veciana, Ignacio de Olazabal

Patent number: 6113229Abstract: An inkjet printing system provides an on/off valve adapted for periodic engagement with an inlet port on a print cartridge mounted in a carriage. The valve is connected to an ink supply which is located off the carriage. A manually actuated set of individual locking gates allows each valve to be separately mounted on a holder capable of carrying multiple valves. As the ink reservoir in the print cartridge is slowly depleted during operation of the printing system, a mechanism periodically moves the valves from a first passive position separated from the print cartridges to a second active position engaged with the inlet port of the print cartridges in order to allow replenishment without removing the print cartridges from the carriage.Type: GrantFiled: March 4, 1998Date of Patent: September 5, 2000Assignee: Hewlett-Packard CompanyInventors: Max Stephen Gunther, Ignacio De Olazabal

Patent number: 6109741Abstract: A printing system which provides active control of the vertical position of an off-carriage ink supply. The system includes an ink-jet print cartridge having an ink reservoir for holding a supply of liquid ink, and an ink replenishment port. A carriage holds the print cartridge, and a carriage scanning apparatus drives the carriage along a carriage scan axis. The system further includes an off-carriage ink supply which is connectable via a fluid path to the ink replenishment port of the cartridge. An elevator apparatus actively raises or lowers the off-carriage ink supply in response to drive commands to position the off-carriage ink supply at a plurality of different elevations relative to a vertical position of the print cartridge to supply ink to the ink replenishment port via the fluid path. The fluid path can be established intermittently, and disconnected during printing operations, or continuously established even during printing operations.Type: GrantFiled: February 27, 1998Date of Patent: August 29, 2000Assignee: Hewlett-Packard CompanyInventors: Rosa Calatayud, Mark E. Young, Elizabeth Zapata, Robert Giles, Ignacio de Olazabal

Patent number: 6012806Abstract: An ink-jet printing system includes a printer frame structure, and a carriage mounted on the printer frame structure for movement across a print zone during normal printing operations and which is positionable in a refill position. A printhead is mounted on the carriage, and has an inlet port accessible without having to remove the printhead. The printing system includes a support bracket attached to the printer frame structure, with an ink supply valve mounted on the support bracket. A clamp structure is mounted on the support bracket and is moveable between a clamping position for engaging the carriage in the refill position and securing the carriage, and a disengaged position wherein the clamp structure is not in contact with the carriage.Type: GrantFiled: February 27, 1998Date of Patent: January 11, 2000Assignee: Hewlett-PackardInventor: Ignacio de Olazabal

Patent number: 5992985Abstract: A variable height reservoir system that allows for reliable ink replenishment to an on-carriage pen reservoir from an off-carriage ink reservoir on an as needed basis. The off-carriage reservoirs are mounted on a platform that is actively moved up and down in a vertical motion. A pen cartridge with an internal spring to provide vacuum pressure is intermittently connected to an off-carriage reservoir, by movement of the pen carriage to a refill station for ink replenishment. In the refill station, a valve is engaged into the pen, thus connecting the ink reservoir to the pen cartridge. Using only the vacuum pressure present in the pen cartridge, ink is pulled into the pen from the reservoir. The ink replenishment occurs in a first stage with the reservoir placed very close to the pen cartridge elevation, with only a small offset between the top of the ink reservoir and the pen nozzles.Type: GrantFiled: March 3, 1997Date of Patent: November 30, 1999Assignee: Hewlett-Packard CompanyInventors: Mark E Young, Rosa Calatayud, Ignacio de Olazabal
