Abstract
A system and method for removing residual toner and submicron particles from a photoconductive drum of a toner-based printer includes an electrified cleaner blade that electrostatically attracts residual toner and submicron particles from the photoconductive drum as the photoconductive drum is rotated towards the electrified cleaner blade. An electrostatic charge unit can be configured to apply a suitable electric charge of between −500 VDC and −2000 VDC to the electrified cleaner blade. Particles lodged on the electrified cleaner blade can be electrostatically dislodged by temporarily reversing the voltage applied to the electrified cleaner blade. Cycling the voltage applied to the electrified cleaner blade between a positive voltage and a negative voltage is used to improve the action of electrostatically dislodging particles lodged on the electrified cleaner blade. The electrified cleaner blade can apply an initial charge to the photoconductive drum.
