ABSTRACT:
A replaceable cartridge, adapted for use with a printing machine having a photoreceptor, is provided. The replaceable cartridge includes a container for storing a selected developer material different from a developer material previously in the printing machine and a programmable memory unit communicating with a control system. The programmable memory is programmed with a reference value reflecting a desired amount of developer material to be developed on the photoreceptor. In operation, the control system detects an actual amount of developer material developed on the photoreceptor and reads the reference value to determine if a difference exists between a value representative of the detected actual amount and the reference value. When a difference exists and the difference is greater than a selected magnitude, a setpoint of the printing machine is adjusted.
