摘要： A particularly configured aperiodic grid for a grid-controlled AC corona charger for uniformly charging a dielectric member, of an electrostatographic reproduction apparatus, moving along a travel path in operative relation to the corona charger. The corona charger includes an insulating housing and an electrically biased grid, in which the grid transparency is larger than a nominal transparency at the upstream edge of the charger grid, transparency is nominal at the center of the grid, and transparency is smaller than nominal at the downstream edge of a charger grid. The invention, which has been demonstrated for negative primary charging, preferably uses a trapezoidal AC waveform having a DC offset for corona excitation, and may be practiced over a large range of process speeds. The invention is also practiced using trapezoidal waveforms having negative duty cycles in the range 50% (conventional AC) to 90% (negative DC). The range of the variation in grid transparency from the upstream grid edge to the downstream grid edge is far greater than in prior art commercial machines.
摘要翻译：一种用于网格控制AC电晕充电器的特别配置的非周期性栅格，用于均匀地对静电放电装置的电介质构件充电，该静电放电装置沿着与电晕充电器有效关系的行进路径移动。电晕充电器包括绝缘壳体和电偏置栅格，其中栅格透明度大于充电器栅格的上游边缘处的标称透明度，透明度标称在栅格的中心，透明度小于标称值充电器网格的下游边缘。已经证明用于负初级充电的本发明优选地使用具有用于电晕激发的DC偏移的梯形AC波形，并且可以在大范围的处理速度下实践。本发明还使用在50％（常规AC）至90％（负DC）范围内的负占空比的梯形波形来实现。从上游网格边缘到下游网格边缘的网格透明度变化的范围远远大于现有技术的商业机器。

摘要： A combination cleaning and surface renewing apparatus includes a cleaning member for removing residual particles from the image-bearing surface of electrostatographic reproduction apparatus. The combination apparatus also includes a first abrading member mounted downstream of the cleaning member for removing at least an atomic layer of material forming the image-bearing surface. The first abrading member is impregnated with abrasive aluminum oxide particles. The combination apparatus also includes a second abrading member mounted downstream of the first abrading member for polishing and renewing the abraded image-bearing surface. The second abrading member includes particles of colorless toner particles chemically bonded therein.
