Patent number: 9988224Abstract: A removable media tray assembly for an image forming device according to one embodiment includes a media tray having a bottom surface and a front wall extending upward from the bottom surface. A bottom surface defines a media storage location for storing a stack of media sheets. The assembly includes a housing having an opening therein to receive the media tray. A magnet and a plate provide a latching force FL greater than a pick motor stall force keeping the media tray in a closed position during media picking. A handle assembly including a finger bar and a pivoting link is mounted to the front wall. With the media tray being held closed by the latching force, a user-supplied actuation force FA that is less than 22.2 N applied to the finger bar, pivots the link which acts as a force multiplier providing a release force exceeding the latching force.Type: GrantFiled: May 30, 2017Date of Patent: June 5, 2018Assignee: Lexmark International, Inc.Inventors: Michael William Lawrence, Dustin Daniel Fichter, Neal Douglas McFarland, Stacey Vaughan Mitchell, Angel Macuha Alagos, Douglas Andagan Baena, Jr., Pat Marlon Cartagena Limosnero

Patent number: 7287922Abstract: A backup roller is formed by a member having a rotational axis and a circumferential region around which a plurality of teeth are arranged. Each tooth of the plurality of teeth has a tip end extending in a direction away from the rotational axis.

Patent number: 7258335Abstract: Drag from media sensor (80) of a printer is eliminated by it being pivoted through a slip connection off of pivoted media feed system (19) to briefly contact papers. The pivoted media feed is then moved in reverse a limited amount at which a rotatably biased member (94) moves ledge (94a) of the member to face abutment surface (92a) of the media sensor. Media feed system 19 is then moved back to drive media while the media sensor is blocked from movement and the slip connection simply slips. After the media is fed, the media feed system is moved away a longer amount while the media sensor is blocked against for the same movement by an abutment (110) in the printer. The media feed system after the longer movement moves a lever (94f) of the biased member and rotates the ledge to free the media sensor to again move to the media.Type: GrantFiled: August 24, 2004Date of Patent: August 21, 2007Assignee: Lexmark International, Inc.Inventors: Kevin Matthew Johnson, Michael William Lawrence, Bryan Christopher Scharf

Patent number: 7198265Abstract: An imaging apparatus includes a printing mechanism having a media path. A print media source is provided for supplying a sheet of print media to the printing mechanism. A drive unit is provided, with a drive shaft coupled to the drive unit. A media sensor device is mounted to the drive shaft, wherein as the drive shaft is rotated in a first direction the media sensor device is moved from a first position that is out of the media path to a second position that is in the media path for sensing the sheet of print media. As the drive shaft is rotated in a second direction opposite to the first direction the media sensor device is moved from the second position that is in the media path for sensing the sheet of print media to the first position that is out of the media path.Type: GrantFiled: August 31, 2004Date of Patent: April 3, 2007Assignee: Lexmark International, Inc.Inventors: Mahesan Chelvayohan, Brian Dale Cook, Timothy Lorn Howard, Kevin Matthew Johnson, William Scott Klein, Michael William Lawrence

Patent number: 7140708Abstract: An edge-to-edge imaging method includes generating a reflectance profile of a mid-frame of an imaging apparatus by taking optical readings along the mid-frame with no print media present in a direction substantially orthogonal to the sheet feed direction, the reflectance profile distinguishing between the media support surface and the waste ink collection trough; taking optical readings across the mid-frame in the direction substantially orthogonal to the sheet feed direction with the sheet of print media present; comparing the optical readings taken with the sheet of print media present with the reflectance profile of the mid-frame; and applying an algorithm to adjust an amount of ink overspray along the lateral edges of the sheet of print media based on a result of the comparing.Type: GrantFiled: August 30, 2004Date of Patent: November 28, 2006Assignee: Lexmark International, Inc.Inventors: Michael William Lawrence, Brian Keith Owens

Patent number: 7121546Abstract: A speed mode for a printer (1) which has a pivotally mounted autocompensating system (19) mounted at an intermediate position in paper guide (17). That system (19) is driven by a motor (40) through a slip drive (70, 72, 74). The motor also drives paper feed system (15). When the motor turns in a direction to feed by system (15), the intermediate system is moved away from the paper guide. In basic operation, when a sheet (5) reaches a position to be fed by the intermediate system, the motor is reversed, and the intermediate system pivots against the paper for moving it further through the paper guide. In the speed mode the intermediate system is not employed and all of the feed is by the system at the tray. Since this will not feed shorter sheets, preferably the speed mode must be positively invoked, as by operator input or definitive information in the header of a print job.Type: GrantFiled: August 12, 2004Date of Patent: October 17, 2006Assignee: Lexmark International, Inc.Inventors: Kevin Matthew Johnson, Michael William Lawrence, Barry Baxter Stout
