Waste toner bottle for uniform distribution of residual toner from an image forming device
First Claim
1. A waste toner bottle for an imaging device, comprising:
- a housing having a reservoir for storing toner, the reservoir having an upper region and a plurality of inlets into the reservoir to receive toner from the imaging device; and
a tube positioned within the reservoir defining an auger path about the housing, the tube in fluid communication with the plurality of inlets and having a transfer auger disposed along the auger path to distribute the toner received from the imaging device in the reservoir, the tube extending from a position below the plurality of inlets upward into the upper region of the reservoir above the plurality of inlets to move the toner received from the imaging device into the upper region of the reservoir,wherein the tube extends from a first end of the reservoir to a second end of the reservoir in the upper region of the reservoir and the tube includes perforations in a bottom of the tube between the first end of the reservoir and the second end of the reservoir in the upper region of the reservoir to drop toner from the tube into the reservoir.

Abstract
A waste toner bottle for an imaging device according to one example embodiment includes a housing having a reservoir for storing toner. A tube defines an auger path about the housing. The tube is in fluid communication with a plurality of inlets of the housing and has a transfer auger disposed along the auger path to move toner into the reservoir. The tube extends upward into the upper region of the housing above the plurality of inlets. The tube extends from a first end of the reservoir to a second end of the reservoir in the upper region of the housing. The tube includes perforations in a bottom of the tube between the first end of the reservoir and the second end of the reservoir in the upper region of the housing to drop toner from the auger path into the reservoir.

14. A method for evenly distributing toner in a waste toner bottle of an imaging device, the waste toner bottle having a housing and an auger for moving toner thereabout and the housing having an upper region, a plurality of inlets for receiving toner from the imaging device and a reservoir for storing toner, the method comprising:
-
receiving toner from the plurality of inlets; directing the received toner to the auger; moving the directed toner upward to the upper region of the housing above the plurality of inlets; and dropping the toner by gravity from the auger in the upper region of the housing into the reservoir beginning at a first end of the reservoir and extending to a second end of the reservoir to fill the reservoir with toner from the first end to the second end, wherein the moving the directed toner upward to the upper region above the plurality of inlets includes moving the directed toner vertically upward along the first end of the reservoir, further comprising moving the directed toner along a substantially horizontal path leading to a point where the directed toner is moved vertically upward along the first end of the reservoir. - View Dependent Claims (15)
