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 diagnosing a photoreceptor associated with an imaging device. The photoreceptor is configured to enter into a diagnostic cycle to complete a set number of cycles. A sensor or array is configured to a scan a component associated with the imaging device during each of the set of cycles to establish defect data. The defect data is analyzed to filter one or more charge deficient spots (CDS) from background noise in the defect data. The systems and methods determine whether the photoreceptor needs replacement based on the determined one or more CDS. The systems and methods are further configured to output a report of the determination. The determination is conducted at fixed or variable intervals throughout the life of the photoreceptor and/or imaging device.

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： This is an electronic scanning probe, preferably made up of at least two sensing elements, each sensing element substantially surrounded by reference electrodes. These sensing elements are separated at a distance that causes little or no cross-interference to take place between these sensing elements when positioned in concert with a surface of interest. Ideally, this probe is used in electrostatic marking systems where an electrostatic charge is placed onto a receiving surface.
