An apparatus for predicting when maintenance is required for a scanner comprises a tracking module configured to track a quality parameter history, a prediction module configured to predict when maintenance is required based on the quality parameter history, and a notification module configured to notify a user when maintenance is predicted to be required based on a quality parameter trend. The quality parameter is selected from a group consisting of an average brightness, a maximum brightness, a video gradient, and a contrast.
