  • Patent number: 9341981
    Abstract: In one example, a printer includes a printer housing, a photoconductor to apply toner to a print substrate, a developer to apply toner to the photoconductor, a light source to expose parts of the photoconductor to light, and a toner container to supply toner to the developer. The toner container housing is integrated into the printer housing as a load bearing structure or as an exterior feature, and/or the light source is integrated into the toner container as a single sub-assembly within the printer housing.

  • Publication number: 20160132012
    Abstract: Printers are disclosed herein. An example printer includes a housing; a non-refillable toner container permanently affixed within the housing, the toner container having a capacity sufficient to store enough toner to print a first number of pages that corresponds to an expected useful life of the printer; and a processor responsive to an input to enable a second number of pages to be printed by the printer, the second number of pages being less than the first number of pages.

  • Patent number: 9244381
    Abstract: In one example, a toner container for an electrophotographic printer includes a toner supply reservoir having a capacity sufficient to store enough toner to print a minimum number of pages that corresponds to a predetermined expected useful life of the printer. In another example, a toner container for an electrophotographic printer includes a toner supply reservoir that, when the container is installed in the printer, extends longitudinally a distance greater than the distance between the light source and the photoconductor and laterally substantially the full axial length of the photoconductor. In another example, a toner container for an electrophotographic printer includes an opening for the imaging light beam and a toner supply reservoir that includes a lower chamber extending laterally under the opening and an upper chamber connected to the lower chamber along both sides of the opening.
