Abstract:
A system for reducing lead edge (LE) smearing in an electrostatographic machine is provided. The system comprises a pretransfer corotron positioned between a developing station and a transfer station in an electrostatographic imaging device. The pretransfer corotron is configured to apply a predetermined charge to at least a portion of a developed toner image on a photoreceptive surface. The predetermined charge is greater than a charge applied to the rest of the developed toner image. The system further includes a controller operably associated with the pretransfer corotron. The controller is configured to activate the pretransfer corotron to apply said predetermined charge to the developed toner image at a lead edge region of the developed toner image when leading edge smearing is detected during imaging operations.
