Reduction of aero-acoustic noise originating from a high-speed polygon mirror scanner motor in a laser beam printer utilizing air-flow analysis

Abstract: This research investigates the aero-acoustic noise originating from a high-speed polygon mirror of a laser beam printer by identifying its source and propagation numerically and experimentally. It calculates the air flow around the polygon mirror scanner motor of a laser printer operating at high speed. Simulated velocity of air flow around the polygon mirror is compared with the experimental velocity measured using a hot-wire anemometer. The frequency spectrum of the air flow around the polygon mirror matches… Show more
