Abstract

A system and method are provided for operating an image forming device in a first processor-controlled toner control operating mode to maintain a substantially constant dispense rate of toner material from a toner source or bottle. The disclosed systems and methods improve toner material dispensing from the toner source or bottle in the image forming device by transitioning to a second processor-controlled toner control operating mode as an amount of toner material in the toner source or bottle is determined to be in a depleted, or nearly-exhausted, state. The disclosed systems and methods compensate for a determined decrease in a toner dispense rate occurring as an amount of toner material remaining in the toner source or bottle is nearly depleted. One or more toner control parameters, including a pixel count gain, are modified in the second processor-controlled toner control operating mode.

First claim

I claim:

1. A system for transporting toner material in an image forming device, comprising:
a toner material source;
a marking engine that deposits toner material on an image receiving media substrate to form an image;
a transport path that delivers the toner material from the toner material source to the marking engine; and
a toner material controller that operates the system in a plurality of operating modes, a first operating mode controlling the delivery of the toner ma…
