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.
