ABSTRACT:
Toner dispensing control in xerographic printing, wherein a toner dispenser is controlled during the initial period of use of a new toner mixture by a first control unit that is at least predominately responsive to the number of discrete exposures of the photoconductor, and during a further period of use a second control unit that is at least predominately responsive to the relative electrical permeability of the toner mixture. Over-tonering during the running-in of a new toner mixture is thereby avoided.
