Abstract

1411210 Toner dispenser FUJI XEROX CO Ltd 26 Feb 1974 [14 March 1973] 8743/74 Heading G2H A control signal, generated each time a predetermined number of copies, e.g. 6, has been made by an electrostatic copying machine, is used to actuate a toner dispenser for a predetermined length of time, e.g. 1 second, whereby the overall amount of toner dispensed is in proportion to the number of copies made by said copying machine. A suitable control circuit is described.
