摘要： The dielectric thickness of a photoreceptor is determined in a variety of ways, including using a relationship between threshold voltage and dielectric thickness, using a relationship between dielectric thickness and the difference between biased transfer roller (BTR) voltage and photoreceptor surface potential, using a relationship between dielectric thickness and biased charging roller (BCR) impedance, using a relationship between dielectric thickness and the slope of the DC current vs. voltage curve for the BTR or the BCR, and using a relationship between dielectric thickness and the BTR voltage at zero current. The threshold voltage can be found by using the slope of the BCR DC current vs. voltage curve, measuring photoreceptor surface potential for a plurality of target values below the charging knee to obtain the intercept value, or finding the actual value of the charging knee. A method of using the BCR as an electrodynamic voltmeter is also disclosed.

摘要： Xerographic photoreceptor life is improved while maintaining output print quality by adjusting the AC charging actuator of a xerographic machine to a point at which photoconductor life is optimized while maintaining output print quality. Where the actuator is voltage, the actuator is set a predetermined amount above the knee voltage of the photoreceptor surface potential versus peak-to-peak voltage curve, which is determined during operation of the machine. Instead of determining the knee voltage, calibration sheets can be generated for various values of the actuator, the best sheet with the least possible actuator value is selected, and the AC charging actuator is set to the value corresponding to the best sheet. The sheets can be evaluated by a user, or an optical array sensor can be used to scan the sheets so that the controller can compare the sheets to stored criteria to automatically select the best sheet and set the actuator. Alternatively, the optical array sensor can scan calibration images directly from the intermediate transfer belt or other image bearing member, thus eliminating the use of paper for calibration.

摘要： Systems and methods of determining a predicted usable life of components, such as a photoreceptor, associated with an imaging device. The systems and methods include a power source configured to increase an electric field across the photoreceptor. A sensor or array is configured to detect charge deficient spots (CDS) in a charge transport layer (CTL) of the photoreceptor as a result of increasing the electric field. The systems and methods are configured to determine the predicted useable life of the photoreceptor based on the detected CDS. The systems and methods are further configured to output a report of the estimation. The estimation is conducted at fixed or variable intervals throughout the life of the photoreceptor and/or imaging device.

摘要： According to aspects of the embodiments, there is provided an adaptive blade lubrication apparatus that includes a lubricant unit to place a lubrication stripe of lubricating material on a portion of a main surface; a cleaning blade that engages the main surface to remove excess toner thereon; and a controller configured to control the location of each lubrication stripe of lubricating material, wherein the controller places the lubricating material based on at least one of application frequency, blade lubrication state, blade engagement with the main surface. By varying the location of the lubrication stripe, the cleaning blade is better lubricated over the entire surface of the photoreceptor with the same or less lubricant than used in single location lubrication. Blade life and reliability are improved with more effective lubrication of the blade.
