  • Patent number: 9063460
    Abstract: A toner cartridge for an imaging apparatus having a housing including two opposed end walls and an elongated body therebetween and an exit port. An inner surface of the body defines a toner reservoir that is communication with the exit port. A drive shaft is rotatably mounted within the housing. A toner platform is provided in slidable contact with the inner surface of the body and is nonrotatable relative to the housing. A drive shaft coupling couples the toner platform to the drive shaft. An exit paddle is positioned adjacent the exit port and is rotatable by the drive shaft. Rotation of the drive shaft translates the toner platform toward the exit port and rotates the exit paddle. As the toner platform moves, toner within the reservoir moves toward the exit paddle and exit port and rotation of the exit paddle moves toner through the exit port.

  • Patent number: 8750763
    Abstract: An image forming apparatus includes a charge roller with improved resistance to defects from prolonged periods of nonuse. The charge roller includes an outermost coating layer including a coating material and filler particles. The filler particles have an average particle size larger than an average thickness of the outermost coating layer in a portion without the filler particles. Furthermore, the filler particles are harder and have a higher glass transition temperature than the coating material.

  • Publication number: 20130275203
    Abstract: A method for selling a replacement supply item according to one embodiment includes in response to a scan of an encoded uniform resource identifier provided on a supply item, identifying a product type and a source type of the scanned supply item. A web page specific to the identified product type of the scanned supply item is then displayed that facilitates ordering the replacement supply item. The displayed web page varies depending on the identified source type of the scanned supply item.
