摘要： A method for detecting a stress condition in a cleaning system of an imaging device is provided. The method comprises receiving a pulse-width modulated (PWM) signal. The PWM signal has a duty cycle for driving a PWM servo motor of a cleaning system. A determination is then made whether the duty cycle of the PWM signal indicates that the servo motor is working within design limits. If the duty cycle is within design limits, characteristic adjustments of the duty cycle of the PWM are detected that indicate an occurrence of a non-catastrophic stress condition in the cleaning system. Once a characteristic adjustment of the duty cycle is detected, an alert signal is generated.
摘要翻译：提供一种用于检测成像装置的清洁系统中的应力状况的方法。该方法包括接收脉冲宽度调制（PWM）信号。 PWM信号具有用于驱动清洁系统的PWM伺服电动机的占空比。然后确定PWM信号的占空比是否表示伺服电机在设计限制内工作。如果占空比在设计限制内，则检测到PWM的占空比的特征调整，其指示在清洁系统中出现非灾难性应力状况。一旦检测到占空比的特性调整，就产生报警信号。

摘要： An ink removal system includes a drip bib and a flexible member. The drip bib collects melted ink flowing down the face of a printhead and the flexible member captures ink dropping from the drip bib after an ink receptacle has received most of the ink collected by the drip bib. When the ink receptacle returns to the position where the receptacle catches melted ink from the drip bib, the receptacle also bends the flexible member and releases the captured ink, which falls into the ink receptacle.

摘要： In order to prevent built up crusts on the flicker assembly from being detrimentally dislodged due to the cleaning fibers impacting the flicker bar assembly, there is provided a soft contact portion flicker bar assembly for mounting in a machine to contact and flick the cleaning fibers moving along a fiber path. The soft contact portion flicker bar assembly includes (a) a base portion for mounting to a frame portion of the machine; (b) a body portion including a distal, first end, and an opposite, second end connected to the base portion; and (c) a tip portion connected to the first, distal end for contacting and interfering with cleaning fibers moving along the fiber path. The tip portion is made of a material having a Shore A durometer hardness of less than 85 for reducing a jarring effect of impact forces between such tip portion and the moving cleaning fibers, thereby preventing detrimental dislodging of built up crusts of particles from any part of the flicker bar assembly.

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： There is disclosed a system for cleaning marking material from a surface portion of a movable photoconductive member. The system includes a first rotatable brush, a blade and a second rotatable brush arranged in sequential order along the movable photoconductive member. The first rotatable brush is for removing a first amount of marking material from the surface portion of the movable photoconductive member as the surface portion of the movable photoconductive member moves past said first rotatable electrostatic brush. The blade, in engaging contact with the movable photoconductive member, is for removing a second amount of marking material from the surface portion of the movable photoconductive member. The second rotatable brush, positioned in interference contact with the movable photoconductive member, is for removing substantially all residual marking material that was not removed by the first rotatable brush and the blade.
