Patent ID: 7817290

Claim:
A method of controlling an electrophotographic print engine, having a plurality of subsystems for enabling rendering of image data, from analyzed image content information, comprising: (a) electronically analyzing, prior to the electrophotographic print engine beginning to print an image, associated image data to generate image content information, the generated image content information including coverage information, potential reload artifact information, and toner pile height information, the toner pile height information specifying locations of toner pile heights within the page; (b) transmitting the image content information to a print engine controller; (c) generating a process speed control signal based on the transmitted image content information, the process speed control signal controlling a speed of a magnetic brush roll of a hybrid scavengeless development developer subsystem within the electrophotographic print engine; (d) generating a temperature fuser control signal based on the transmitted image content information, the temperature fuser control signal differentially controlling a temperature of a fuser, within the electrophotographic print engine, across a page being rendered and differentially controlling a temperature of the fuser, within the electrophotographic print engine, between a start and an end of the page being rendered; and (e) generating a toner flow rate control signal based on the transmitted image content information, the toner flow rate control signal controlling a rate of flow of toner in the hybrid scavengeless development developer subsystem.
