摘要： Exemplary embodiments provide charging systems and methods for effectively delivering charges onto a receptor. The charging system can include a low velocity gas stream, an emitter assembly for providing cathode-to-anode field bias to generate charges from the low velocity gas stream, and an emitter-to-receptor (e.g., photoreceptor) electric bias to enhance the charge delivery to the receptor. The disclosed charging systems and methods can be used to achieve an optimal charging performance at a low projected cost for any suitable receptor that needs to be charged. Exemplary receptors can include a photoreceptor (PR) such as a belt PR or a drum PR, a toner layer, a sheet of media on which toner can be deposited, or a transfer belt in an electrophotographic printing machine.

摘要： A charging device comprises first and second electrodes forming a charging zone. A plurality of nanostructures adhere to at least one of the first and second electrodes. A charging voltage supply couples to the electrodes to support the formation of gaseous ions in the charging zone. An aperture electrode or grid proximate to the first and second electrodes is coupled to a grid control voltage supply which grid control voltage supply, in turn, controls a flow of gaseous ions from the charging zone to thereby charge a proximately-located receptor. In one embodiment, the charging voltage supply is arranged to provide a pulsed-voltage waveform. In one variation of this embodiment, the pulsed-voltage waveform comprises a pulsed-DC waveform. In another embodiment, the charging voltage supply is arranged to provide an alternating-current waveform. In one embodiment, the charging device itself is comprised in an image forming device.

摘要： A coronode charging device includes a support member, a filament, an adjustment mechanism and a voltage source. The lament is disposed along the support member in a configuration that creates a plurality of active regions and a plurality of inactive regions of the filament. The active regions are simultaneously positionable adjacent the photoreceptor. The inactive regions may be farther from the photoreceptor than the active regions. The adjustment mechanism moves the filament such that portions of the filament that correspond to the active regions are moved to positions that correspond to the inactive regions, and some portions of the filament that were in the inactive regions are moved to positions that correspond to the active regions. This operations extends the life of the coronode charging device.

摘要： This is an electronic scanning probe, preferably made up of at least two sensing elements, each sensing element substantially surrounded by reference electrodes. These sensing elements are separated at a distance that causes little or no cross-interference to take place between these sensing elements when positioned in concert with a surface of interest. Ideally, this probe is used in electrostatic marking systems where an electrostatic charge is placed onto a receiving surface.
