  • Publication number: 20110183241
    Abstract: Embodiments pertain to a novel imaging member, namely, an imaging member or photoreceptor comprising a protective outer layer which comprises light-absorbing composition that substantially prevents any light absorption by the overcoat layer. The composition comprises a low strength thermal plastic resin and a high optical density yellow dye. Thus, the light-blocking protective layer reduces the intrinsic light shock suffered by conventional overcoat layers without negatively impacting electrical properties of the overcoat layer and while improving print quality.

  • Patent number: 7949268
    Abstract: 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.
