Abstract: A cleaner band stretchably disposed, across the imaging surface width, between two rotating cleaner brushes. The cleaner band is slightly off center and down process from the brush backup roll. The cleaner band acts as a disturber for dislodging large agglomerate residual particles from the imaging surface.
Abstract translation: 在两个旋转的清洁器刷之间跨越成像表面宽度可伸缩地设置的清洁带。 清洁器带从刷子支撑辊稍微偏离中心和下方。 更清洁的带作为用于从成像表面移除大的聚集残留颗粒的干燥器。

Abstract: An apparatus for reducing electrostatic charge of particles in a waste container. In one embodiment the waste container is coated with a liquid having a viscosity sufficient to prevent tribocharging between the waste container and the waster toner particles, and to collect toner particles deposited from the cyclone separator into the waste container. Another embodiment describes the use of a flange extending into the waste container to prevent tribocharging that can cause explosions in the waste toner bottle.
Abstract translation: 一种用于减少废物容器中的颗粒的静电荷的装置。 在一个实施方案中，废物容器被涂覆有具有足以防止废物容器和废弃调色剂颗粒之间的摩擦增加的粘度的液体，并将从旋风分离器沉积的调色剂颗粒收集到废物容器中。 另一个实施例描述了延伸到废物容器中的凸缘的使用，以防止可能引起废调色剂瓶中的爆炸的摩擦增压。

Abstract: Apparatus and method for minimizing ghost defect are disclosed. Ghosting results in interdocument bands when paper size is changed and process control instability due to using the interdocument zone (IDZ) for voltage and density control. A controller retrieves feedback measurements of the IDZ and sheet zone (SZ) non-uniformity. In response to the measurements, the transfer current IDZ level is controlled to minimize differences in subsequent charging, photodischarge and development.
Abstract translation: 公开了用于使重影缺陷最小化的装置和方法。 当纸张尺寸发生变化时，由于使用文档区域（IDZ）进行电压和密度控制，重影会导致文档内容带宽和过程控制不稳定。 控制器检索IDZ和片区（SZ）不均匀性的反馈测量值。 响应于测量，转移电流IDZ电平被控制以最小化后续充电，光电放电和开发中的差异。

Abstract: Apparatus and method for minimizing ghosting defects and process control instabilities for a printing system are disclosed. According to an exemplary embodiment, a controller retrieves uniformity measurements of an interdocument zone (IDZ) and sheet zone (SZ). In response to the uniformity measurements, a transfer current IDZ level is controlled to minimize differences in subsequent charging, photodischarge and/or development associated with the IDZ and SZ.

Abstract: A printhead cleaning device includes a housing having an opening and an ink receptacle positioned within the opening. A member extends from the ink receptacle and through the opening. The member is configured to contact a faceplate of a printhead to enable liquid ink emitted onto the faceplate to move from across the member into the ink receptacle.
