摘要: A controls system architecture for an image output terminal (IOT) has a hierarchical structure which isolates subsystem purposes of efficient algorithm design, analysis and implementation. The is preferably divided into three levels supervisor provides isolation functions reliability assurance functions. improves quality IOT outputs by controlling the operation to ensure that toner reproduction curve matches tone input image, despite several uncontrollable variables change image.
