Abstract: A seal assembly for inhibiting toner leakage comprises a j-seal received by a developer housing in a toner cartridge. The j-seal has an upper seat portion engagably sealing with a doctor blade seal and a leg for slidably sealing of a developer roll. The upper seat portion has an upper seat inner seal wall and an upper seat outer seal wall spaced apart a preselected distance from said upper seat inner seal wall and defining a gap therebetween. A doctor blade seal engages the upper seat inner and outer seal walls and a doctor blade bracket assembly disposed adjacent the j-seal and the doctor blade seal. The doctor blade seal further has a tongue disposed within the gap for interlocking said j-seal and sealably engaging the doctor blade bracket assembly.

Abstract: A toner seal comprises a j-shaped seal having an upper seat portion and a leg portion, the leg having a front face extending between first and second edges of said leg portion, a lip seal extending along at least one of the first and second edges of the leg, and, the lip seal having a length extending from the upper seat portion along the leg.

Abstract: A toner feeding device and method to supply toner from a toner reservoir to a selected location in the printer such as a toner supply roll. The toner feeding device may contact with a portion of an inner wall of a toner reservoir and may flex and may subsequently recover to convey toner particles.

Abstract: Embodiments for a toner auger for use in an image forming device. The image forming device includes a channel through which toner is moved. The auger is positioned within the channel and has an axis of rotation and at least one offset section extending radially outward from the axis of rotation. The offset section forms a sweep envelope that extends outward from the axis of rotation. The auger may be positioned within the channel for the offset to contact the channel. Contact may cause a vibratory force that prevents the toner from clogging and bridging within the channel.

Abstract: Embodiments of a device to move waste toner within an image forming device. In one embodiment, waste toner is formed during the image formation process. The waste toner is captured and moved through a first conduit. The conduit includes an outlet for passing the waste toner to a second conduit. The door is positionable between an open orientation to allow the waste toner to discharge into the second conduit, and a closed orientation. The second conduit includes an inlet for receiving the waste toner. The interface between the first and second conduits allows for the door to move between the open and closed orientations. The interface also greatly reduces or prevents the waste toner from leaking as it passes from the first conduit into the second conduit.

Abstract: The present invention is directed to an article, system and method for determining and/or selecting the location of a toner engaging member in a developing agent device such as a toner cartridge. The article, system and method may be applied to a printing device such as a laser printer.
