Abstract
An electrophotographic image forming device may use a feedback loop to determine environmental conditions and accordingly set one or more operating parameters. The device may detect a resistance/capacitance characteristic of a feedback loop comprising an interface between a first component and a second component of an image forming unit. The interface may be one in which a toner image is transferred during image forming device operation. A controller may adjust the detected resistance/capacitance characteristic in response to an age of one of the first component or the second component, thereby accounting for the age or wear of the components.
