Patent number: 11754969Abstract: A toner cartridge according to one example includes first and second alignment guides that extend outward from a first side and a second side of the toner cartridge, respectively, for positioning the toner cartridge. The first and second alignment guides define a pivot axis about which the toner cartridge is pivotable relative to an imaging unit when the toner cartridge is installed on the imaging unit. An engagement member is positioned on a rear of the toner cartridge for receiving a bias force for biasing the toner cartridge about the pivot axis when the toner cartridge is installed on the imaging unit. The engagement member is positioned next to the bottom of the housing. The engagement member includes an angled contact surface that faces upward and rearward for contacting a corresponding hold-down on the imaging unit when the toner cartridge is installed on the imaging unit.Type: GrantFiled: April 21, 2022Date of Patent: September 12, 2023Assignee: Lexmark International, Inc.Inventors: Brian Scott Carpenter, Gregory Alan Cavill, James Richard Leemhuis, Jeffrey Lawrence Tonges

Patent number: 11635706Abstract: A toner cartridge according to one example embodiment includes a reservoir for holding toner. An outlet is positioned on a front of the toner cartridge for exiting toner from the toner cartridge. First, second and third electrical contacts are positioned on a first side of the toner cartridge for contacting corresponding first, second and third electrical contacts in an image forming device. Each of the first, second and third electrical contacts of the toner cartridge is electrically connected to a respective imaging component positioned on the toner cartridge. The first, second and third electrical contacts of the toner cartridge are positioned such that an imaginary line that angles downward in a direction from a rear of the toner cartridge toward the front of the toner cartridge passes through the first, second and third electrical contacts of the toner cartridge.Type: GrantFiled: May 23, 2022Date of Patent: April 25, 2023Assignee: Lexmark International, Inc.Inventors: Brian Scott Carpenter, Gregory Alan Cavill, Jeffrey Lawrence Tonges

Patent number: 11086247Abstract: An assembly for an electrophotographic image forming device according to one example includes a rotatable roll having an electrically conductive shaft. An electrically conductive bracket is positioned adjacent to the roll and in a spaced relationship from the roll along a length of the roll. An electrical contact is positioned to receive an electrical voltage from a power supply of the image forming device. The electrical contact is electrically connected to a first end portion of the shaft of the roll by way of a first electrical path and to a second end portion of the shaft of the roll by way of a second electrical path to transfer the electrical voltage to the roll. The bracket forms a portion of the second electrical path such that the electrical voltage transferring from the electrical contact to the second end portion of the shaft of the roll passes through the bracket.Type: GrantFiled: October 28, 2020Date of Patent: August 10, 2021Assignee: Lexmark International, Inc.Inventor: Jeffrey Lawrence Tonges
