Abstract
A method for method for operating a printing machine to maintain developer material within in a predefined state by monitoring the state of materials in a developer and automatically scheduling corrective action before print quality becomes significantly impacted. The corrective action can include forcing an increase in toner usage by periodically generating and developing images having high toner density.
Claims11
A method for operating a printing machine to maintain developer material within in a predefined state, comprising:
- developing an image to thereby provide increased toner usage in response to a diagnosis of toner health;
- and
- repeating the developing step until an efficacious amount of toner to maintain the developer material within in the predefined state has been used.
A method for operating a printing machine to maintain developer material within in a predefined state, comprising:
- monitoring health of the material in the developer housing;
- and
- forcing an increase in toner usage in response to a diagnosis of toner health.
A method for operating a printing machine having a plurality of developer stations to maintain developer material within in a predefined state, comprising:
- monitoring developer material health at each developer station within the plurality of developer stations to detect unhealthy developer material;
- upon detecting unhealthy developer material in at least one of developer stations, configuring a toner purge;
- and
- performing the toner purge.
