Abstract
An electrostatographic toner image reproduction machine is provided for producing toner reproductions of original images. The reproduction machine includes a frame; a movable image bearing member mounted to and having a path of movement within the frame; and electrostatographic process devices mounted for forming a toner image, transferring and fusing the toner image onto a copy sheet; and at least one status parameter defining a quality condition of the formed, transferred and fused toner images. The reproduction machine also includes measuring devices for measuring the at least one status parameter; at least first and second different machine speeds at which to operate the machine; and a machine controller connected to the measuring devices for automatically changing the machine speed in response to each of the at least one status parameter so as to ensure continued production of high quality toner images. The machine controller is programmed to read a Start-Of-Copy (SOCS) status of the at least one status parameter; a rate of change (ROC) of the at least one status parameter; an acceptable Normal End-Of-Copy value range (NEOCVR) of the at least one status parameter; and a Defaul…
