Abstract

Xerographic printers collect waste toner in a waste container which is replaced when full. Some printers use cyclonic air flow within the waste toner process that results in a cone-shaped pile of toner in the waste container. This pile can prematurely activate the sensor that warns the container is full. This idea proposes two methods to eliminate the cone-shaped mountain of waste toner that builds up in the waste toner box as it fills. As toner is augured from the xerographic system to the waste toner box, the air flow is such that it forms a cone or pyramid shaped pile of toner that is higher in the middle than the outer border. This often trips the sensor in the box that alerts the operator the waste toner box is full. Using only 60% of the available space of the box increases run cost and creates excess waste material. By placing a membrane with a series of holes at the top of the toner box, the toner is distributed across the component and allowed to drop through the holes, which eliminates the vortex that causes the cone shaped toner pile. This method can be used on existing waste toner boxes but needs some design improvements to stay in place in the box. The second proposal is to place an "X" shaped piece of cardboard in the bottom of the box when the box is opened and installed. The four chambers formed by the insert would allow toner to fill in one by one as they reach the top of the insert and spill into the adjacent chamber.

Cyclone Waste Flow Impeder

Xerographic printers collect waste toner in a waste container which is replaced when full.  Some printers use cyclonic air flow within the waste toner process that results in a cone-shaped pile of toner in the waste container.  This pile can prematurely activate the sensor that warns the container is full. This idea proposes two methods to eliminate the cone-shaped mountain of waste toner that builds up in the waste toner box as it fills. As toner is augured from the xerographic system to the waste toner box, the air flow is such that it forms a cone or pyramid shaped pile of toner that is higher in the middle than the outer border. This often trips the sensor in the box that alerts the operator the waste toner box is full. Using only 60% of the available space of the box increases run cost and creates excess waste material.

The four chambers formed by the insert would allow toner to fill in one by one as they reach the top of the insert and spill into the adjacent chamber.

The cyclone waste flow impeder is designed to interfere with the cyclone vortex as the toner waste is moved in the waste box from the toner waste system.  With the impeder in place inside the container, it will efficiently fill the waste container...
