Abstract
A method and computer program for preventing excess supply of toner in an imaging device include detecting a change in a tribo-electric charge of toner after a period of inactivity of the imaging device, compensating a toner dispense control value, such as a PID (Proportional, Integral, Differential) value, based on the detected change in the tribo-electric charge of toner, and outputting the compensated toner dispense control value. A system for preventing excess supply of toner includes a sensor that detects a change in a tribo-electric charge of toner after a period of inactivity of the imaging device, and a controller that compensates the toner dispense control value based on the detected change in the tribo-electric charge of toner and outputs the compensated toner dispense control value. The detected change may be based on a charge prior to the inactivity.
