"Apparatus for loading, processing cartridge for use in a printing machine, and printing machine eletrofotogru00e1fica".It is a device of loading for the application of a uniform electrostatic charge to a surface blocking load.The apparatus includes a housing and an arrangement of electrodes supported by the housing and pin adjacent to the surface in a relation of lack of contact.The apparatus also includes a generally U-shaped shield connected to the housing and surrounding at least partially the arrangement of pin electrodes.The apparatus also includes a grid positioned through the distal extremities of the shielding. The cage defines an extension of the load effectively and a width of the grid effectively.The apparatus also includes a source of energy supply to operationally coupled to the electrode pin to supply a current previously determined to house one of the electrodes DAnd the pin. The power supply provides a predetermined voltage to the grid.At least one of the magnitude of the current, the magnitude of the voltage, the extension of load effectively, and the width of the effective grating being selected so as to optimize the uniformity of the load.To minimize the sensitivity of the grid element at the photo receiver, and to minimize ozone generated in the inside of the apparatus of loading.
