Abstract
Abstract An improved metering system is provided for an electrostatic reproduction machine, the latter being capable of operating in either an automatic document handling mode or a manual mode. The system counts the number of originals per job up to a predetermined first number, the total number of originals fed into the machine, and the total number of prints made. What is counted depends on whether the machine is in the automatic mode or in the manual mode and how many prints the machine is programmed to produce.
