Abstract:
1. A system for increasing the density of toner stored in a toner container comprising: a container for storage of toner in an xerographic reproduction machine, the container having a body that defines an internal volume and a fill opening in the container body, and a porous plug mounted in another opening in a wall of the container body; the porous plug having a first end, which is mounted in the other opening, and a second end, which is located within the internal volume of the container for storage of toner, the porous plug extending from the first end to the second end a distance that is at least approximately 20% of a distance between the wall of the container in which the other opening is located and a position on an opposing wall defining the internal volume, the porous plug remaining within the internal volume of the container throughout operational use of the container in a xerographic reproduction machine; a filling system for mating to the fill opening of the container to provide toner through the fill opening for storage within the internal volume of the container; and a source of negative pressure coupled to the porous plug to remove air from the internal volume of the container and more densely pack the toner stored in the container.
