In a method and apparatus for raster scanning optical output device, such as a laser printer or the like, an array of independently addressable light emitting devices, such as an array of solid state lasers, is used to control spot position on an image plane in the slow scan direction. The array is disposed such that the spots emitted from each element of the array impinge the image plane displaced in the slow scan direction from one another. The total distance between all the spots is less than the distance between fast scan direction scan lines. Only a single element of the array is operated per scan line, thus only a single spot is formed on the image plane per scan line. Control of which of the elements of the array emits a light beam per scan line allows control of the spot position in the slow scan direction for that scan line.

Dans une méthode et un dispositif destinés à un appareil de sortie optique à balayage de trame, comme une imprimante laser ou un appareil semblable, un réseau de dispositifs émetteurs de lumière à adresses distinctes, comme un réseau de lasers à semi-conducteurs, commande la position du spot sur un plan image dans la direction du balayage lent. Le réseau est placé de telle sorte que les spots émis par chacun des éléments du réseau qui frappent le plan image sont déplacés l'un par rapport à l'autre dans la direction de balayage lent. La distance totale entre tous les spots est inférieure à la distance entre les lignes de balayage dans la direction de balayage rapide. Seul un élément du réseau est activé par ligne de balayage, de sorte qu'un seul spot se forme sur le plan image par ligne de balayage. Comme la présente invention permet de commander lequel des éléments du réseau émet un faisceau lumineux par ligne de balayage, il est possible de commander la position du spot dans la direction de balayage lent pour la ligne de balayage en question.
