摘要： An indirect printer includes a system for alternating the pressure in a transfer nip by manipulating the transfer roller. The system includes a pair of pivotable collars mounted about the ends of the transfer roller. The collars are pivoted towards or away from one another to bend the transfer roller and to increase or decrease, respectively, the pressure in the longitudinal center of the nip.

摘要： An inkjet printer includes a plurality of color separation modules. Each color separation module includes an image receiving member and a printhead module configured to eject ink drops onto the image receiving member to form a color separation on the image receiving member. The printer is configured to transfix each color separation on each image receiving member to a single sheet to produce a composite ink image on the print medium after the print medium has passed by all of the color separation modules in the printer.

摘要： A method monitors an electric current supplied to an electrostatic brush within a printing device. The electrostatic brush contacts and cleans a photoreceptor surface within the printing device. The method records a current spike pattern of when the electric current exceeds a first current threshold during the monitoring; however, the method will stop operations of the printing device if the electric current exceeds a second current threshold that is greater than the first current threshold. Further, the method can determine whether a scratch is present on the photoreceptor surface based on the current spike pattern.

摘要： A cleaning blade assembly within a printing device is positioned to contact a surface to be cleaned. There is a first opening within the cleaning blade assembly and a first pin within the first opening. There is also a second opening within the cleaning blade assembly, and a second pin within the second opening. The first and second pins connect the cleaning blade assembly to the printing device. The first pin has a first cam surface that is rounded and is off-center with respect to the axis of the first pin. The cam surface is parallel to the axis of the first pin and is positioned within the first opening such that rotation of the first pin within the first opening causes the cleaning blade assembly to move in a direction perpendicular to the axis of the first pin.

摘要： This is a shim cleaning blade for use in a novel cleaning station of an electrophotographic marking system having an a-Si photoconductive surface. The cleaning blade is preferably made from stainless steel but other metals can be used if suitable. The blade has a thickness of about 0.05-0.2 mm, but best results are obtained when using a thickness of about 005-0.1 mm. The cleaning blade contacts the photoconductive surface it is cleaning at an angle of from about 2 to about 40 degrees.

摘要： A method for controlling blade interference in a single blade or multi-blade xerographic cleaner based on a look-up table for environmental conditions and blade age. Temperature and humidity sensors and a blade age counter are used to provide information to a controller, which adjusts the blade interference through a stepper motor based on the preloaded table. This allows lower blade load in most conditions over life, compared to the known method of setting the initial load high enough to cover these stress factors at worse case levels. The look-up table is empirically determined for a give blade material and xerographic system, e.g., photoreceptor, toner, etc. It takes into account the variation in blade load itself as a function of the environment and blade age.
摘要翻译：基于用于环境条件和叶片年龄的查找表，用于控制单个叶片或多叶片静电印刷清洁器中的叶片干涉的方法。温度和湿度传感器和叶片寿命计数器用于向控制器提供信息，控制器通过基于预加载的工作台的步进电机来调整刀片干扰。与在较差情况下将初始负载设置得足够高以覆盖这些应力因子的已知方法相比，这允许在大多数条件下寿命较低的叶片负载。根据经验确定查找表给予叶片材料和静电复印系统，例如感光体，调色剂等。它考虑到叶片负载本身作为环境和叶片年龄的函数的变化。

摘要： A method for controlling a xerographic single or multiple blade cleaning subsystem includes sensing the actual cleaning blade load against a photoreceptor with a transducer and adjusting it to a desired value. A feedback loop through a stepper motor will set the desired load by changing blade to photoreceptor interference. This will correct for the effects of piece part tolerances, blade modulus changes with environment and set with age. A single transducer and positioning system can achieve the desired average blade load, or one at each end can also keep the load even from end to end.

摘要： A transfer cleaning station for an electrostatic marking system is provided. In this station, the upper surface of a movable transfer belt is cleaned by a rotating electrostatic cleaning brush (ESB). To improve cleaning performance and conserve space, a grounded conductive brush is placed below an inside surface of the belt so that an electrostatic cleaning field is created between it and the ESB. The grounded conductive brush is located in a previously unused space between two upper rollers in the station.
