TONER DISPENSING CONTROL

摘要

Toner dispensing control Toner dispensing control in xerographic printing, wherein a toner dispenser is controlled during a first period of use of a new mixture by means that is responsive to the number of discrete exposures of the photoconductor, and during a further period of use by means that is responsive to the relative permeability of the toner mixture. The improved control avoids over-tonering during the running-in of a new toner mixture. (Fig. 2)
