  • Patent number: 7383014
    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.

  • Patent number: 7257363
    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.

  • Patent number: 6572105
    Abstract: A diverter to direct media within an image forming apparatus along one of three media paths. A first gate and a second gate are positioned in an overlapping arrangement and each is movable between up and down positions. Each of the gates includes a biasing member to bias the gates towards the down position. An actuator contacts the second gate to move it to the up position. The overlapping arrangement of the first and second gates causes the first gate to also be moved to the up position when the second gate moves to the up position. A second actuator contacts the first gate to move the gate from the down position to the up position independently of the second gate.
