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: 7072066Abstract: A method and apparatus for saving power in a printing system, by prioritizing printer jobs. Using a graphical user interface an end-user assigns a print time to a first job. The print time designation is attached to the first job and the first job is transmitted from the end-user station to a printer. Based on whether the printer is in ready state or in power save mode the first job is printed immediately or stored in memory. When the first job is stored in memory, computations are made to determine a printing time to initiate printing of the first job. The first job is then printed at the printing time or at an earlier printing time if a second job with an earlier printing time is stored in the memory.Type: GrantFiled: June 30, 2003Date of Patent: July 4, 2006Assignee: Hewlett-Packard Development Company, L.P.Inventor: Srinivas Guddanti

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: 6883797Abstract: A sheet feeding system has a pick roller, a first roller, and a second roller. The ends of the first and second rollers are coupled together. The pick roller acquires, or picks, a sheet from a stack of sheets and passes the sheet to the first and second rollers. One of the first and second rollers discourages unintended sheets passed with the sheet picked from the stack. The other of the first and second rollers advances the sheet. A logic processor evaluates interchange conditions and activates a drive mechanism when the evaluated interchange conditions reaches a threshold value. The drive mechanism interchanges the first and second rollers so that the second roller becomes the first roller and the first roller becomes the second roller.Type: GrantFiled: May 3, 2002Date of Patent: April 26, 2005Assignee: Hewlett-Packard Development Company, L.P.Inventors: Srinivas Guddanti, Chet M.

Patent number: 6741342Abstract: This invention relates to the method and apparatus for indicating roller wear in a media handling device. Such structures of this type, generally, employ the use of a laser beam that is located adjacent to the media handling device roller. Initially, the roller material obstructs the laser beam. However, when the roller becomes worn out, the roller material no longer obstructs the laser beam and the beam shines on a piece of reflective material that is illuminated when the laser beam contacts it. This illumination will then be seen from the front of the media handling device, such as through the use of an LED. The laser beam can also activate an optical sensor that relays information to the user.Type: GrantFiled: April 10, 2002Date of Patent: May 25, 2004Assignee: Hewlett-Packard Development Company, L.P.Inventors: Chet M.

Publication number: 20030184785Abstract: A system and method for printing print friendly media. A printer includes a display, a bar code scanner and a database of printer characteristics. Bar coded media is scanned using the bar code scanner. The database of printer characteristics is then searched for the optimum printer configuration for printing on the scanned media. The optimum configuration information is then displayed to an operator through the printer window. As an alternative, the optimum configuration information is used to automatically adjust the printer, to optimize printing on the media.Type: ApplicationFiled: March 29, 2002Publication date: October 2, 2003Inventor: Srinivas Guddanti

Patent number: 6619656Abstract: A paper tray automatically adjusts to accommodate a variety of media sizes. An array of photodetectors on the support surface of the tray are masked from light by placing media in the tray. A controller determines the size of the media by monitoring which photodetectors have been masked. The controller can then direct tray guides to move to predetermined positions corresponding to the size of the media.Type: GrantFiled: January 25, 2002Date of Patent: September 16, 2003Assignee: Hewlett-Packard Company, L.P.Inventors: Srinivas Guddanti, Chet M.
