    摘要： A defect analysis system for a xerographic print engine includes a residual mass sensor that senses the two-dimensional signature structure of residual mass remaining on a photoconductive or other substrate surface after image transfer. Preferably, the sensor is a full width array that spans substantially an entire width of the photoconductive surface. This information is then processed and analyzed to determine a specific type of transfer defect present. This may include the quantified level of defect for each detected type. The defect analysis system may also include a closed-loop control system that can adjust various xerographic process parameters using feedback based on the identification and optionally magnitude of each specific defect type. The identified print quality defect, such as mottle, streaks, point deletions, graininess, etc. can then be used to determine a customized corrective control action to be taken by the feedback control of the xerographic print engine to remedy or compensate for the defect(s).

    摘要： A transfer charging device is arranged with dual transfer-assist blades consisting of a pressure blade and a halo blade. The pressure blade is arranged for contacting and thereby urging a substrate against an image-bearing photoreceptor. The pressure blade is formed of a relatively conductive material. The halo blade is formed of a dielectric material. The halo blade is positioned between the transfer charging device and the pressure blade to shield the pressure blade from being charged-up by the transfer charging device.
