ABSTRACT:
The length of an ink jet filament as a function of stimulation amplitude is measured in an ink jet printing apparatus by locating a narrow charging electrode near the drop break-off point of the ink jet filament, varying the stimulation amplitude to vary the filament length, and measuring the amount of charge imparted to the ink drops as the filament length is changed. Stimulation amplitude is automatically adjusted by as a function of the measured charge.
