摘要： An adaptive cleaner blade lubricating system for electrophotographic printing machines. In an electrophotographic printing machine, the amount of residual toner available to lubricate a cleaner blade is calculated based on the density of the transferred image. A band of toner is deposited in an inner document gap in selective widths so as to provide an adequate amount of toner to lubricate the cleaner blade across the full width of the photoreceptor. The lubricating band may be variable or may be a constant width with the frequency of placement of the band determined based on average image density for a group of documents. In the preferred embodiment, the width of the toner band is varied as a function of the overall residual toner in each pixel location across the width of the photoreceptor based on the density of the images transferred. As a result of the varying lubrication bands, the cleaner blade is maintained so as to not tuck and cause streaking and/or damage while toner efficiency is maximized.
摘要翻译：适用于电子照相印刷机的清洁剂刮板润滑系统。在电子照相印刷机中，基于转印图像的密度计算可用于润滑清洁器叶片的残留调色剂的量。调色剂带以选择的宽度沉积在内部文件间隙中，以便提供足够量的调色剂以在感光体的整个宽度上润滑清洁器刀片。润滑带可以是可变的或可以是恒定宽度，并且基于一组文档的平均图像密度确定的带的放置频率。在优选实施例中，调色剂带的宽度根据所传送的图像的密度而随着感光体宽度的每个像素位置中的总体残留调色剂的变化而变化。作为不同润滑带的结果，清洁器叶片被保持为不会卷起并且在调色剂效率最大化时引起条纹和/或损坏。

摘要： An apparatus in which a donor roll advances toner to an electrostatic latent image recorded on a photoconductive member. A plurality of electrode wires are positioned in the space between the donor roll and the photoconductive member. The electrode wires extend in a transverse direction relative to the longitudinal axis of the donor roll. The electrode wires are electrically biased to detach the toner from the donor roll so as to form a toner cloud in the space between the electrode wires and photoconductive members. Detached toner from the toner cloud develops the latent image. Electrode wires contact a portion of the surface of the donor roll. As the donor roll rotates, friction between the electrode wires and donor roll causes trapped debris to move away from the toner powder cloud region so as to minimize contamination produced streaks on the developed image.
摘要翻译：供体辊将调色剂提前到记录在感光体上的静电潜像的装置。多个电极线被定位在供体辊和感光体之间的空间中。电极线相对于供体辊的纵向轴线在横向方向上延伸。电极线被电偏置以从供体辊分离调色剂，以便在电极线和感光体之间的空间中形成调色剂云。从调色剂云中分离的调色剂产生潜像。电极线接触供体辊表面的一部分。当供体辊旋转时，电极线和供体辊之间的摩擦使得捕获的碎屑远离调色剂粉末云区域，以便最小化在显影图像上产生的条纹的污染。
