Abstract
A toner monitor system includes a toner monitor having an output signal which is proportional to the toner concentration of a measured development mixture and further to an applied control voltage. The control voltage is set such that the toner monitor output voltage midpoint is constant regardless of environmental changes. The output voltage is centered at mid range for a nominal toner concentration, and the control voltage setting used to center the toner monitor output voltage at its midpoint is stored during a setup cycle. A reference member having a temperature stable magnetic permeability is positioned to align with the toner monitor so as to simulate to the toner monitor a nominal toner concentration, wherein the control voltage setting centers the toner monitor output voltage at its midpoint for the nominal toner concentration.
