Abstract
A plurality of copying machines (12), (13), (14) are connected to a computer (39). Each copying machine (12), (13), (14) comprises sensor means (16), (17), (18), (19), (21), (22), (23), (24) for sensing various operating parameters thereof such as a total number of copies produced, machine malfunctions, amounts of remaining copy sheets and toner, etc. These parameters are all transmitted to the computer (39) which processes and prints them out. In response to a copying machine malfunction the computer (39) feeds back to the malfunctioning copying machine instructions for correction. The instructions are displayed at the copying machine. The computer (39) further computes the degree of degeneration of the photoconductive element of each copying machine (12), (13), (14) and controls the imaging exposure intensity and developing bias voltage in accordance therewith.
