Patent number: 7142122Abstract: Detection of a potential user of an imaging device is utilized to begin the initialization of the imaging device prior to when the user is expected to access the imaging device. By beginning the initialization process prior to the user's expected access of the device, wait time experienced by the user may be reduced without a need to continuously maintain the device in a full powered-up state or even to maintain the device in a stand-by state.Type: GrantFiled: November 14, 2001Date of Patent: November 28, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Chet Butikofer, Robert W. Jewell

Patent number: 7131646Abstract: A system and method for improved accessibility of media output from a media processing device. Media receivers are coupled to an actuator such that the media receivers can be moved under manual command by a user, or automatically by a controller. Movement selectors are provided for activation thereof by a user. The user selects a media receiver for movement, and then the desired direction of movement. The media receiver is moved to a position most convenient for the user so that the media in the media receiver is most accessible to that user. In an illustrative embodiment, a laser printer with a plurality of paper trays is adapted to the present invention.Type: GrantFiled: November 2, 2001Date of Patent: November 7, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Srinivas Guddanti, Chet Butikofer

Patent number: 7000914Abstract: Imaging apparatus and methods include providing an input support surface to support input imaging media and an output support surface to support output imaging media. The input support surface is configured to move relative to the output support surface, wherein such movement is in response to the drawing, or picking, of input imaging media from the input support surface, and wherein such movement is also proportional to the quantity of input imaging media picked from the input support surface.Type: GrantFiled: April 13, 2002Date of Patent: February 21, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventors: Srinivas Guddanti, Chet Butikofer

Patent number: 6905119Abstract: A roller for use in an imaging system includes a variable hardness, fluid-pressurizable roller core, and a roller cover surrounding the roller core. A source of pressurized fluid can be used to pressurize the roller core to a fixed, predetermined pressure prior to installation of the roller core in an imaging system. Alternatively, a variable-pressure source of pressurized air can be used to variably pressurize the roller core during operation of the imaging system.Type: GrantFiled: June 19, 2002Date of Patent: June 14, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Srinivas Guddanti, Chet Butikofer

Patent number: 6881972Abstract: A media processing system retrieves a sheet of media and transports it to an imaging process. Misalignment of media from retrieving and transporting is removed by a media realignment process which wedges the leading edge of the media into stopped rollers while additionally advancing the trailing edge of the media for a predetermined distance. The media flexes and forms an arching buckle which aligns parallel to the leading edge of the media with the stopped rollers, thereby removing the skew of the media in relationship with the stopped rollers. The amount of over-advancement of the trailing edge of the media is modified according to the stiffness of the media. A media stiffness sensor measures the media stiffness by quantifying the deflection of the media when a portion of the media is cantilevered into deflection-measuring sensors. Imaging processes are also improved by employing media stiffness measurements to modify imaging processes.Type: GrantFiled: November 4, 2002Date of Patent: April 19, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Chet Butikofer, Robert Jewell
