Abstract:
An electrophotographic printing machine in which an electrostatic latent image recorded on an imaging surface is developed with toner particles to form a visible image thereof, comprising:a hopper containing a supply of carrier material;a first developer unit for developing the electrostatic latent image with toner particles of a first color;a second developer unit for developing the electrostatic latent image with toner particles of a second color;means for connecting said first and second developer unit to said hopper so that carrier material flows to said first and second developer unit;a first feeding system, in communication with said connecting means, for regulating the amount of carrier to said first developer unit;a second feeding system in communication with said connecting means for regulating the amount of carrier to said second developer unit;a controller for controlling the regulation rate of said first and said second feeding system independently; anda temperature sensor and humidity sensor, said temperature sensor and humidity sensor being in communication with said controller, for sending data associated in determining said predefined regulation rate.
