With reference to the drawing, a customer electronic charge back control system is used for controlling a copier/duplicator in a multi-customer site for the purpose of charging back to various customers costs for machine usage/time period. The concept utilizes a data entry keyboard or other data input media, for each customer to program in their access code to enable the machine to switch to ready state. At end of customer usage, the machine would exit either automatically or manually to inhibit state until a customer enters a recognizable code. At periodic intervals, each code can be entered into the machine and for each code, the appropriate number of copies or cost (if model billing is incorporated) is displayed in the control panel or other media output like mag tape, hard copy, etc. This output shows allocation of machine usage per customer for a given time period. An infinite number of codes could be utilized with programmed recognition.
