ABSTRACT:
A system, including an improved sensor, for determining toner particle uniformity is described. The sensor measures toner particle charge, typically be having the charge on the toner particle control a current flow through the channel of a thin film transistor. By measuring the charge on many toner particles, the system determines whether sufficient toner degradation has occurred that the toner should be replaced. The sensor is particularly suitable for being formed on a thin diagnostic sheet that is input through the paper path of a printing system.
