A system and method for performing real-time quality inspection of objects is disclosed. The system and method include a transport to move objects being inspected, allowing the inspection to be performed in-line. At least one optical acquisition unit is provided that captured optical images of the objects being inspected. The captured optical images are matched to CAD models of objects, and the matched CAD model is extracted. A laser with an illumination light beam has a wavelength in the violet or ultraviolet range then conducts scans of the objects, which are formed into three-dimensional point clouds. The point clouds are compared to the extracted CAD models for each object, where CTF are compared to user input or CAD model information and the object is determined to be acceptable or defective based on the extent of deviation between the point cloud and the CAD model.

Fuser assemblies, xerographic apparatuses including the fuser assemblies, and methods of fusing toner on media in xerographic apparatuses are disclosed. An embodiment of the fuser assemblies comprises a first roll including an electrically-conductive first surface; an electrically-conductive second surface, the first surface and the second surface defining a nip therebetween at which toner is fused on a medium; at least one voltage sensor for sensing a first voltage difference between the first surface and the second surface; and at least one power supply connected to the first surface and the second surface. A controller is connected to each voltage sensor and each power supply. The controller receives a signal from each voltage sensor indicating the first voltage difference, and the controller controls each power supply to produce a second voltage difference between the first surface and the second surface based on the first voltage difference.
