ABSTRACT:
A method for maintaining developer material within in a predefined state through the scheduling of increased toner throughput coordinated among multiple developer housings. The method monitors developer material health at each developer station within a plurality of developer stations to detect unhealthy developer material. If unhealthy developer material is detected in at least one of developer stations, a toner purge state is identified for each of the remaining developer stations. Based on the toner purge states, a toner purge is performed.
