ABSTRACT:
The present invention generally relates to a digital imaging system. More specifically, the present invention provides an improved method and apparatus for calculating toner age using a toner concentration sensor and mass sensor to ensure image quality by anticipating or diagnosing problems in image quality, which may be caused by toner age. These problems include low developability, high background, and halo defects appearing on sheets of support material.
