Abstract: An apparatus for controlling the denseness of powder conveyed from a hopper through a funnel and into a container includes an auger that is positioned within the funnel that is rotatable and vertically movable. The rotation and vertical movement of the auger serves to continuously vary the length of the auger and as a result maximizes the mass of powder that can fill the container. Alternatively, the auger can include an articulatable section that splays when it is extended beyond a terminal portion of the funnel. Still yet, the device could include a hollow auger shaft with an internal rod that has the ability to extend and retract. The rod includes a strip portion and with the strip portion retracted, the powder discharged is in its densest state. As the strip portion is extended the powder density is reduced.

Abstract: A sheet to sheet electronic skew correction system measures the input skew of each incoming sheet “on-the-fly” with sensors and then adjusts the image electronically to match the skew of the particular sheet. Thus, the image placed on the sheet from a photoreceptor is square with the dimensions of the sheet since the image is an exact match with the skew orientation of the sheet.

Abstract: A pre-registration system increases the latitude of present active registration systems by decreasing the lateral offset of sheets before they reach the active registration system. This is accomplished by pivoting a long transport with a stepper motor in conjunction with sensing a lateral edge of the sheets in order to direct the sheets to the proper lateral position to be fed into the active registration system with a minimum of lateral offset.

This is accomplished by pivoting and translating a sheet supply elevator with stepper motors in conjunction with sensing a lateral edge of sheets in order to direct the sheets to the proper lateral position to be fed into the active registration system with a minimum of lateral offset.
