  • Patent number: 8538286
    Abstract: A cartridge for containing toner material used in an image-forming device according to one example embodiment includes a developer roll, two J-seals that provide interfaces with the developer roll at the ends thereof, and an air duct that conducts airflow across the interfaces to cool the developer roll and seals. The air duct is an unitary structure including an elongated hollow body and a pair of nozzles in fluid communication with the hollow body. One of the nozzles is disposed at a distal end of the developer roll near one J-seal, and the other of the nozzles is disposed at a proximal end of the developer roll near the second J-seal.

  • Patent number: 8150297
    Abstract: The present invention provides a toner container system, such as a toner cartridge, having a first reservoir for containing toner and a second reservoir for receiving toner from the first reservoir and transferring the toner to an image forming apparatus, and a toner transfer mechanism disposed between the first and second reservoirs, the transfer mechanism including a generally cylindrically shaped rotatable roller member having a plurality of equally spaced recesses disposed around the circumference thereof and being rotatable in angular increments wherein the recesses are alternately open to the first reservoir in a first position for each recess and open to the second reservoir in a second position for each recess, whereby toner is transferred from the first reservoir to the second reservoir upon rotation of the roller member, a Geneva drive mechanism including a drive gear operatively connected to the roller member for advancing the roller member in one angular increment for each complete rotation of the

  • Patent number: 7590373
    Abstract: The present disclosure relates to a device and/or method for conveying a quantity of image forming material between selected regions in a printing device or printer cartridge. A roller is provided having a surface that may include a recess capable of transferring a quantity of image forming material. The recess may include a convex surface. A wiper is configured to engage at least a portion of the roller surface and/or the convex surface in the recess to assist in the removal of image forming material that may otherwise accumulate on the roller surfaces. Such roller design and wiper configuration may therefore cooperate to improve the consistency of image forming material transfer.

  • Publication number: 20080226351
    Abstract: The present application is directed to devices for moving toner within an image forming device. In one embodiment, the device includes a reservoir with an inlet that leads into the reservoir through a first sidewall. New toner may be introduced through the inlet and into the reservoir. A paddle may be positioned within the reservoir to move the toner from the inlet and through the reservoir. The paddle may prevent the toner from accumulating at the inlet which may act as a block to prevent further toner from being moved into the reservoir. The paddle may include a shaft with a weighted first arm extending from the shaft in a first direction and a second arm extending from the shaft in a second direction. The arms are weighted such that the first arm is heavier than the second arm. The paddle is positioned within the reservoir such that rotation of the paddle moves the toner from the inlet throughout the reservoir.
