Patent number: 9389576Abstract: A deskewing plug and assembly mountable in a frame having a first and a second shaft forming a nip therebetween with the second shaft rotatably mounted in a pair of opposed channels and biased toward the first shaft for adjusting the axial alignment of the shafts. The deskewing plug has a generally cylindrical body having first portion, a second portion and a tab portion. The second portion has a circumferential camming surface cooperatively engageable with the second shaft. Rotation of the plug and camming surface adjusts the axial alignment of the second shaft. The tab portion radially extends from the first portion and has radially extending ridges frictionally engageable with a wall of the opening in the frame to prevent rotation of the deskewing plug after adjustment. A cap may be provided to cover and frictionally engage the tab with the cap being fastenable to the frame.Type: GrantFiled: December 19, 2014Date of Patent: July 12, 2016Assignee: Lexmark International, Inc.Inventors: Brian Lester Boettcher, Mark Duane Foster, Michael David Maul, Joshua Carl Poterjoy

Patent number: 9317004Abstract: A replaceable unit for an electrophotographic image forming device includes a housing having a photoconductive drum rotatably mounted thereon. The photoconductive drum has a rotational axis. A guide channel on an exterior of the housing extends parallel to the rotational axis of the photoconductive drum and is positioned to guide insertion of the housing into the image forming device. A positioning stop on the housing is movable between a latching position and an unlatching position. In the latching position the positioning stop obstructs at least a portion of the guide channel to limit the travel of the replaceable unit in the image forming device parallel to the rotational axis of the photoconductive drum. A release handle on the housing is operatively connected to the positioning stop to move the positioning stop from the latching position of the positioning stop to the unlatching position of the positioning stop.Type: GrantFiled: May 29, 2015Date of Patent: April 19, 2016Assignee: Lexmark International, Inc.Inventors: Brian Lester Boettcher, Michael David Maul, Jennifer Marie Murphy, Joshua Carl Poterjoy

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
