摘要： A method and apparatus for accessing the uniformity of a charging subsystem with a resolution which enables one to make accurate predictions of customer acceptance of the charging device. The method and apparatus employs a scanner that scans the light emitted from a recording member such as a phosphor coated substrate while the charging device under test is in operation against the substrate, the uniformity of device can be processed using off-the-self image analysis tools. This enables imaging the generated charge pattern with improved spatial resolution and offers a quantitative technique to measure charge uniformity.

摘要： An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet by providing an electric field of predetermined magnitude at a transfer zone. The transfer station includes a rotatable transfer member, with a cleaning corotron associated therewith. A control system for maintaining a constant current at the transfer zone takes into account a current supplied by the cleaning corotron. The control system can also take into account current leakages associated with the transfer member.

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.
