Method of setting laser power and developer bias in an electrophotographic machine based on an estimated intermediate belt reflectivity
Abstract
A method of calibrating an electrophotographic (10) machine having an image-bearing surface includes estimating a reflectivity of the image-bearing surface based upon an amount of usage of the electrophotographic machine (10). At least one electrophotographic condition is adjusted dependent upon the estimating step.
