<p>A printer (20) includes a movable print carriage (40) for reciprocatingly scanning along a carriage scan axis, a printhead (54, 56) having a plurality of ink jet nozzles and supported by the movable print carriage, a print media moving mechanism (29) for moving print media along a media axis through a print zone (25), and a vibration inducing piezoelectric element (61) for causing relative vibration between the printhead (54, 56) and the print media such that locations along a media axis of dots printed by the ink jet nozzles are minutely randomly varied to reduce otherwise visible banding caused by poor paper advance or misdirected nozzles. <IMAGE></p> |
