ABSTRACT:
A toner detecting system includes an image forming apparatus having a toner reservoir. A toner sensor of the system has a toner sensing element of piezoelectric material, the toner sensor carried within the toner reservoir to detect a toner level condition. A driver of the system is disposed to structurally excite at least a portion of the toner sensor when the portion is not immersed in toner, the excited at least a portion stressing the toner sensing element so as to impart a detectable output signal indicative of flexing of the toner sensor. A detector of the system is configured to receive the detected output signal and detect the toner level condition.
