Publication number: 20180164717Abstract: 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 projects from the front of the housing and is spaced from the exit port toward the first side of the housing. The projection extends further forward than a frontmost portion of the exit port. A front of the projection is unobstructed for engaging a shutter on a developer unit when the toner cartridge is inserted into the image forming device.Type: ApplicationFiled: February 6, 2018Publication date: June 14, 2018Inventors: BENJER ALBARAN ACOSTA, JAMES ANTHANY CARTER, II, GARY NEAL HACKNEY, KATRINA ROSIT LACTUAN, JAMES RICHARD LEEMHUIS, KEITH SEAMAN, BRYAN CHRISTOPHER SCHARF, MATTHEW LEE ROGERS, CHRISTOHPER GENE VOWELS, JASON HALE, MARK WILLIAM AMANN, BENJAMIN KEITH NEWMAN, HARALD PORTIG, RODNEY EVAN SPROUL

Patent number: 9921522Abstract: An electrophotographic image forming device according to one example embodiment includes a toner cartridge having 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 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 exposed at the rear of the housing near the first side of the housing for receiving a first engagement feature in an image forming device. A forward facing opening is exposed at the front of the housing near the first side of the housing for receiving a second engagement feature in the image forming device. The forward facing opening overlaps with the rearward facing in a side-to-side dimension of the housing.Type: GrantFiled: April 20, 2017Date of Patent: March 20, 2018Assignee: Lexmark International, Inc.Inventors: Benjer Albaran Acosta, James Anthany Carter, II, Gary Neal Hackney, Katrina Rosit Lactuan, James Richard Leemhuis, Keith Seaman, Bryan Christopher Scharf, Matthew Lee Rogers, Christohper Gene Vowels, Jason Hale, Mark William Amann, Benjamin Keith Newman, Harald Portig, Rodney Evan Sproul

Patent number: 9910403Abstract: A replaceable unit for an electrophotographic image forming device according to one embodiment includes a pocket formed on a first side of a housing. A bottom end of the pocket is open for receiving an electrical connector during insertion of the replaceable unit into the image forming device. An electrical contact is positioned within the pocket and is electrically connected to processing circuitry on the housing. An outer guide is positioned on the first side of the housing and below the pocket. A portion of the outer guide inclines inward toward the first side of the housing as the outer guide extends upward. An inner guide is positioned within the pocket on a first inner surface of the pocket, which faces toward the first side of the housing. A portion of the inner guide inclines inward toward the first side of the housing as the inner guide extends upward.Type: GrantFiled: December 20, 2016Date of Patent: March 6, 2018Assignee: Lexmark International, Inc.Inventors: Mark William Amann, Gregory Alan Cavill, Katrina Rosit Lactuan, James Richard Leemhuis, Darren Wayne Tosh

Patent number: 9671750Abstract: An imaging unit for an electrophotographic image forming device having positional control features for aligning the imaging unit in a supporting frame in the image forming device. The positional control features include on each end wall, first and second bullet noses and a stop arm positioned between the two bullet noses. The first and second bullet noses engage support or datum surfaces provided in corresponding openings in the frame. The stop arm receives a biasing force that rotates the imaging unit into its final operating position. A latching assembly is provided on one end wall to prevent the imaging unit from ejecting from the frame.Type: GrantFiled: February 10, 2016Date of Patent: June 6, 2017Assignee: Lexmark International, Inc.Inventors: Brian Lester Boettcher, Jeffrey Alan Abler, Mark William Amann, Donn Duane Bryant, Geoffrey Kirk Carlson, Paul Douglas Horrall, Michael David Maul, Jennifer Marie Murphy, Joshua Carl Poterjoy
