Patent number: 9122203Abstract: A remanufactured toner cartridge includes a wall defining a fill hole that is used to refill the cartridge with toner. A patch covers the fill hole, and a heat activated adhesive non-removably attaches the patch to the wall. The fill hole can be formed with a heat knife such that when the heat knife is withdrawn it forms a raised ridge of material extending around the perimeter of the fill hole. The patch is attached to the wall by applying heat and pressure to the patch, which also softens and at least partially flattens the ridge of material surrounding the fill hole such that the patch is substantially flush with the wall upon completion of the operation.Type: GrantFiled: January 30, 2014Date of Patent: September 1, 2015Assignee: CLOVER TECHNOLOGIES GROUP, LLCInventors: Heymo Hormannn, Paul Michael Korzenecki

Patent number: 9031452Abstract: A method for restoring an imaging cartridge chip, applicable in the technical field of imaging. In the process of restoring the imaging cartridge chip, a laser beam is used at least to unseal a location where a functional interface is on a storage device comprised in the imaging cartridge chip, or at least to scratch open or to drill open packaging material at the location where the functional interface is, then restore data is written into the storage device via the functional interface and a read/write interface. This results in the repair of the imaging cartridge chip.Type: GrantFiled: March 27, 2012Date of Patent: May 12, 2015Assignee: Apex Microelectronics Co., Ltd.Inventor: Yangyun Zeng

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
