摘要： An apparatus which cleans particles from a tracking region on a photoconductive drum. A spacer maintains the spacing between the photoconductive drum and a developer roller substantially constant. The spacer contacts the photoconductive drum in the tracking region. The cleaning member, mounted on a transfer roller, removes particles adhering to the tracking region so as to ensure that there is no build up of particles in the tracking region changing the spacing between the photoconductive drum and the developer roller.

The toner composition also exhibits improved dry rheological properties and improved fix properties. These improved properties make this toner composition useful for higher speed printing while using less toner.

摘要： A xerographic marking engine adjusts a charging actuator value, such as an AC peak-to-peak voltage or an AC peak-to-peak current, based on a determined knee value, VKNEE, of a charge curve for an imaging apparatus photoreceptor within the xerographic marking engine and environmental sensor data. The environmental sensor data may measure environment temperature and environment humidity. In near A-zone environments, for example, operational environments in which the temperature is 80 degrees Fahrenheit and the relative humidity is 80%, the charging actuator value may be selected to achieve a predetermined photoreceptor wear rate that avoids print quality defects due to lateral charge migration. In other than A-zone environments, the charging actuator value may be selected to minimize the photoreceptor wear rate, while avoiding print quality defects. The described approach allows optimal photoconductor wear to be achieved, in all operational environments, without increasing the risk of print quality defects.

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 a charging assembly that is useful in marking processes with an electrostatically charged surface. The assembly includes, besides the charger, a controller and an electric field probe. Charge and current flows can be detected by the probe and corrected immediately after detection of flaws by the probe and conveyed to the controller. If flaws in the charger are determined by the probe, corrections are made to the output by a controller; this is done before a final copy or print is made. The term flaws as used means any non-uniform appearing region in the printed image or any otherwise unacceptable defect. The probe is enabled to detect and indicate flaws and the controller which is in communication with the probe takes corrective action on the flaws. The probe used is a novel probe having two sensing elements surrounded by one or more reference electrodes.
