ABSTRACT:
An electrostatographic machine is disclosed with at least one adjustable process control parameter. The machine receives and electronically stores electrical image information signals of an original. A reproduction of the original is created using the received electrical image information signal, and a second electrical image information signal is in turn created from the reproduction. The second electrical image information signal is compared with the first electrical image information signal to produce an error signal representative of differences therebetween. The process control parameter is adjusted in response to the error signal to minimize said differences.
