摘要： According to aspects of the embodiments, there is provided an apparatus comprising a cleaning unit with a blade holder that rotates about a pivot point, the cleaning blade is coupled to the blade holder and is positioned to chisel excess toner from a photoreceptor surface. Geometrical changes produce a blade having a plurality of slanted surfaces at the working end of the blade one at an obtuse angle, in the range of 93 degrees to 97 degrees, and a second at an acute angle that forms an offset point between the cleaning edge and the intersection of the two angles. A double cut allows for improvement in the cleaning tip stiffness using the first cut, while the second cut increases the contact width and improves the pressure distribution at the working edge.

摘要： A transfix roller is adapted for use with a thin walled image receiving member in an indirect printer. The transfix roller is centrally supported to present a more uniform pressure profile in the nip formed with the image receiving member. An interference fit between the central shaft and the roller sleeve enables the transfix roller to be made without an additional process to secure the shaft to the sleeve.

摘要： According to aspects of the embodiments, there is provided an apparatus and method to manage the contact of a cleaning blade and a moving surface to increase the useful life of the blade. For example, a cleaning apparatus for a photoreceptor surface comprises a cleaning unit with a blade holder that rotates about a pivot point, a cleaning blade that is coupled to the blade holder and is positioned to chisel excess toner from the photoreceptor surface, and which cleans excess toner from the photoreceptor surface. The apparatus further comprises a sensor that senses the start and the end of an operational procedure, and an actuator that rotates the blade holder about the pivot point to selectively advance or retract the blade during the start-up procedure and the shut-down procedure. After the cleaning surface has begun to move or reached operating speed, blade contact is increased to bring the blade load up to operational level. By making this change to the conventional static cleaning blade, the peak stress at start-up and shut-down is much reduced and cleaning blade life and reliability are much improved.

摘要： Electrostatic printing machines require different types of paper with different width and thickness. In relation to the paper thickness and width is a phenomenon called the End Leakage Current Effect whereby highly positive voltage can be found in the non-paper contact area of a photoreceptor surface after the transfer stage. The paper transfer stage is when the paper touches the photoreceptor and an image is transferred onto the paper. This effect can result in cleaning failure and potential non-uniformity on the photoreceptor surface. The extent of the end leakage current effect depends on the thickness and width of the paper to which the image is being transferred. Adjusting the pre-clean corotron current based on paper thickness and width provides a remedy for the end leakage effect. Sufficient corona treatment can be provided to the residual toner to enable proper cleaning of the photoreceptor when the pre-clean corotron current is adjusted accordingly.
摘要翻译： 静电印刷机需要不同类型的不同宽度和厚度的纸张。 关于纸的厚度和宽度是称为末端泄漏电流效应的现象，由此在转印阶段之后在感光体表面的非纸张接触区域中可以发现高电压。 纸张传送阶段是当纸张接触感光体并且图像被转印到纸张上时。 这种影响可能导致感光体表面的清洁失败和潜在的不均匀性。 端漏电流效应的程度取决于传输图像的纸张的厚度和宽度。 根据纸张厚度和宽度调整预清洁电晕电流可以为端漏效应提供补救。 可以向剩余调色剂提供足够的电晕处理，以便当相应地调节预清洁对角线电流时能够适当地清洁感光体。
