ABSTRACT:
A control method for monitoring the cleaning performance of a single or multiple blade xerographic cleaning subsystem includes looking at the photoreceptor post-cleaner with a full width array sensor and adjusting the blade load on the photoreceptor to the minimum required to maintain effective cleaning. Blade load is adjusted using a stepper motor. Monitoring of cleaning failures can be done during non-print time, when a toner patch is developed to evaluate cleaning. Re-adjustment is needed periodically since environmental stresses can change, and the blade ages due to set and wear. Two toner patches at the ends of the blade with two stepper motors can be used to assure the same load from end to end.
