Patent number: 9031451Abstract: An example toner cartridge includes a reservoir for containing toner and an exit port in fluid communication with the reservoir. A shutter is positioned at the exit port and movable between an open position and a closed position. A first linkage member is operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature. A second linkage member is pivotally attached to a side wall of the housing and biased toward a home position. A third linkage member is movable with the second linkage member. When the second linkage member is in the home position, the third linkage member is in a blocking position preventing the first linkage member from opening the shutter. When the second linkage member pivots away from the home position, the third linkage member moves to a non-blocking position permitting the first linkage member to open the shutter.Type: GrantFiled: February 28, 2013Date of Patent: May 12, 2015Assignee: Lexmark International, Inc.Inventors: Darrell Stephen Rulon, John Andrew Buchanan, James Anthany Carter, II, Gregory Alan Cavill, Mark Duane Foster, Benjamin Keith Newman, Matthew Lee Rogers, Keith Seaman, Christopher Gene Vowels, Tyler Frederick Williams

Patent number: 9020405Abstract: A doctor blade assembly for the developer unit of an electrophotographic imaging system. The doctor blade assembly includes a blade member having a first longitudinal edge for contacting a developer roll of an imaging system; a bracket member operatively connected to the blade member; and at least one bias member having a first end portion along a first longitudinal end portion of the bracket member and a second end portion contacting a distal portion of the blade member so as to present a force thereon. The force presented by the bias member serves as a counterforce to at least partly offset a force presented on the doctor blade and developer roll by a seal member of the developer unit.Type: GrantFiled: February 9, 2012Date of Patent: April 28, 2015Assignee: Lexmark International, Inc.Inventors: Nicholas Fenley Gibson, Brad Edward Mattingly, Benjamin Keith Newman

Publication number: 20150098733Abstract: A toner cartridge for use in an image forming device according to one example embodiment includes a housing having a reservoir for containing toner therein. The housing has an exit port in fluid communication with the reservoir. A shutter is positioned at the exit port that is movable between an open position and a closed position. The shutter is biased toward the closed position. A linkage is operatively connected to the shutter to open the shutter upon being actuated by a first engagement feature in the image forming device. An interlock is operatively engaged with the linkage and biased toward a locked position preventing the linkage from opening the shutter. The interlock is movable to an unlocked position that is disengaged with the linkage when the interlock is actuated by a second engagement feature in the image forming device permitting the linkage to open the shutter.Type: ApplicationFiled: December 16, 2014Publication date: April 9, 2015Inventors: Benjamin Keith Newman, Matthew Lee Rogers, Christopher Gene Vowels

Patent number: 8977160Abstract: An shutter having an overmolded seal for use in controlling the flow of toner through a port in a toner containing supply items for an imaging apparatus. In one form the shutter is overmolded with a seal comprised of a sleeve and one or more integrally molded angled endless ribs projecting outwardly from the sleeve. With the shutter installed in the supply item, the ribs deflect creating an sealing interface with the housing of the supply item to prevent toner leakage between the shutter and the housing of the supply item.Type: GrantFiled: December 30, 2011Date of Patent: March 10, 2015Assignee: Lexmark International, Inc.Inventors: John Andrew Buchanan, James Anthany Carter, II, Benjamin Keith Newman, Matthew Lee Rogers, Christopher Gene Vowels

Publication number: 20150003877Abstract: A toner cartridge according to one example embodiment includes a housing having a reservoir for containing toner therein. An exit port in fluid communication with the reservoir faces downward on a front of the housing near a first side of the housing. A portion of a main interface gear for providing rotational power to a toner delivery system is exposed on the front of the housing near a top of a second side of the housing and engagable with a corresponding drive gear in the image forming device. A projection extends forward from the housing further forward than a frontmost portion of the exit port and is spaced from the exit port toward the first side of the housing. A front of the projection is unobstructed for engaging a developer unit when the toner cartridge is inserted into the image forming device.Type: ApplicationFiled: September 18, 2014Publication date: January 1, 2015Inventors: Benjer Albaran Acosta, James Anthany Carter, II, Gary Neal Hackney, Katrina Rosit Lactuan, James Richard Leemhuis, Keith Seaman, Bryan Christopher Scharf, Matthew Lee Rogers, Christopher Gene Vowels, Jason Hale, Mark William Amann, Benjamin Keith Newman, Harald Portig, Rodney Evan Sproul

Patent number: 8867966Abstract: A toner cartridge according to one example embodiment includes a housing that defines a reservoir for containing toner. An exit port in fluid communication with the reservoir faces downward on the front of the housing near a first side. A shutter positioned at the exit port is movable between an open position and a closed position. A toner delivery system for transferring toner from the reservoir includes a main interface gear exposed on the front of the housing near the top of the second side. A rearward facing opening is positioned near the first side of the housing for receiving a first engagement feature in an image forming device for opening and closing the shutter. A forward facing slot is positioned near the first side of the housing for receiving a second engagement feature in the image forming device for locking and unlocking the shutter.Type: GrantFiled: December 30, 2011Date of Patent: October 21, 2014Assignee: Lexmark International, Inc.Inventors: Benjer Albaran Acosta, Mark William Amann, James Anthany Carter, II, Gary Neal Hackney, Katrina Rosit Lactuan, James Richard Leemhuis, Benjamin Keith Newman, Matthew Lee Rogers, Rodney Evan Sproul, Jason Hale, Harald Portig, Keith Seaman, Bryan Christopher Scharf, Christopher Gene Vowels
