Publication number: 20200064767Abstract: A server including instructions to perform a method for managing replacement of a consumable in an imaging device, which includes, determining a remaining life of a consumable installed in the imaging device; determining an average number of pages printed in the imaging device during a predetermined period; identifying a number of days of use remaining based upon a rated life of the consumable, the remaining life of the consumable, and the average number of pages printed; and determining whether the number of days of use remaining is within a predefined floor range. Upon at least one of a determination that the number of days of use remaining is within a predetermined threshold and that the remaining life of the consumable is within a predefined floor range, an order for a replacement consumable for the imaging device is created and placed in an order fulfillment system.Type: ApplicationFiled: September 28, 2018Publication date: February 27, 2020Inventors: Ryan Luke Merin Daque, David Lynn Groce, Steven John Loboyko, David John Mickan, Kimberly Lisa Preston, Matthew Lee Rogers, Gregory Scott Tigges, Jason Carl True

Patent number: 9563162Abstract: An electrophotographic image forming device according to one embodiment includes a controller configured to provide a page countdown for a replaceable toner cartridge of the image forming device on a display screen. The controller, upon detecting an installation of an imaging unit previously mated with a first toner cartridge that was out of usable toner and detecting a presence of a second toner cartridge, is configured to determine whether the second toner cartridge is out of usable toner. The controller is configured to determine a number of pages remaining for a page countdown associated with the life of the second toner cartridge and whether the toner sump of the imaging unit contains sufficient toner to print the number of pages remaining for the page countdown associated with the life of the second toner cartridge if the second toner cartridge is out of usable toner.Type: GrantFiled: April 12, 2016Date of Patent: February 7, 2017Assignee: Lexmark International, Inc.Inventors: Thad Carlton Switzer, Jason Carl True

Patent number: 9335656Abstract: An electrophotographic image forming device according to one example embodiment includes a replaceable unit having a reservoir for storing toner and a rotatable shaft positioned within the reservoir. The replaceable unit has a first magnet and a second magnet connected to the shaft and rotatable around an axis of rotation of the shaft in response to rotation of the shaft. An amount of angular offset between the first magnet and the second magnet varies depending on an amount of toner in the reservoir. A sensor is positioned to sense the first magnet and the second magnet at a point in their rotational paths. A processor is in electronic communication with the sensor and configured to determine an angular offset between the first magnet and the second magnet and to adjust an estimate of the amount of toner remaining in the reservoir based on the determined angular.Type: GrantFiled: December 1, 2014Date of Patent: May 10, 2016Assignee: Lexmark International, Inc.Inventors: Brian Scott Carpenter, Robert Watson McAlpine, Jason Carl True

Patent number: 9304467Abstract: A method for providing a page countdown for a replaceable unit of an image forming device according to one embodiment includes calculating a number of pages remaining until the replaceable unit will reach the end of its life. The calculated number of pages remaining until the replaceable unit will reach the end of life is displayed on a display screen. After the calculated number of pages remaining is displayed, the displayed number of pages remaining is decreased in response to printing of pages by the image forming device, the number of pages remaining is recalculated and a discrepancy between the displayed number of pages remaining and the recalculated number of pages remaining is tracked. If the discrepancy exceeds a predetermined error threshold, the recalculated number of pages remaining is displayed and the displayed number of pages remaining continues to be decreased from the displayed recalculated number of pages remaining.Type: GrantFiled: April 22, 2015Date of Patent: April 5, 2016Assignee: Lexmark International, Inc.Inventors: Delbert Lester Elliott, Steven Wayne Parish, Kevin Dean Schoedinger, Jason Carl True

Patent number: 8755719Abstract: A developer unit for use in an image forming device according to one example embodiment includes a housing having an inlet port for receiving toner, a sump for holding received toner and a developer roll rotatably mounted in the housing for transferring toner from the sump. A rotatable agitator is positioned in a lower portion of the sump and a pivotable agitator is positioned in an upper portion of the sump. A biasing member biases the pivotable agitator toward a stop in the pivot path of the pivotable agitator. The pivotable agitator includes an engagement feature positioned in the rotational path of the rotatable agitator when the pivotable agitator is in its home position. As the rotatable agitator rotates, the rotatable agitator engages and disengages the engagement feature causing the pivotable agitator to pivot away from and toward its home position.Type: GrantFiled: June 18, 2012Date of Patent: June 17, 2014Assignee: Lexmark International, Inc.Inventors: Joshua Carl Poterjoy, Jason Carl True
