Patent

CA 2309596

The invention relates to a method and a device to control a paper drive- mechanism (8) which is devoid of a sprocket feed in an electrographic printer that outputs data on a pre-printed striplike recording medium (5). Said recording medium (5) has the same optical marking (109) on all pages. In a start operation, the front edge (110) of the recording medium (5) is inputted into an input zone (69) at a specific insert mark (65a), whereupon said recording medium (5) is conveyed by means of a conveyor motor (41, 102) in direction (A) at a given length and at a first relatively low speed. A sensor (59,85) scans a specific area of the recording medium (5) during the conveyance process and transmits scanning signals to an evaluation device (100). The evaluation device (100) examines whether the scanning signals coincide with the marking characteristics (109) and the length of conveyance between two similar successive markings (109) is identified by the evaluation device (100) as a page length value. The printing process is initiated at a second relatively high speed of conveyance and conveyance is controlled according to the identified page length value.

L'invention concerne un procédé et un dispositif pour commander un dispositif d'entraînement de papier (8) sans roues à picots dans une imprimante électrographique qui transfère des informations sur un support d'impression (5) en forme de bande constitué de pages portant chacune un marquage (109) optique similaire. Au cours d'une opération de démarrage, le bord avant (110) du support d'enregistrement (5) est appliqué, dans une zone d'introduction (69), sur une marque d'insertion (65a) prédéterminée de l'imprimante. Ensuite, le support d'impression (5) est avancé, par un moteur de transport (41, 102), d'une longueur prédéterminée, dans le sens de transport (A). Un capteur (59, 85) balaye, pendant le processus de transport, une zone prédéterminée du support d'enregistrement (5) et envoie des signaux résultant du balayage à un dispositif d'évaluation (100). Ce dispositif d'évaluation (100) détermine si les signaux résultant du balayage correspondent aux caractéristiques du marquage (109), et la longueur de transport comprise entre deux marquages (109) similaires successifs est identifiée par le dispositif d'évaluation (100) comme valeur correspondant à une longueur de page. Ensuite, le processus d'impression est lancé à une seconde vitesse de transport relativement élevée et le transport est commandé en fonction de la valeur identifiée comme correspondant à une longueur de page.
