Title
(EN) INK JET TYPE IMAGE FORMING DEVICE
(FR) DISPOSITIF DE FORMATION D'IMAGE DE TYPE A JET D'ENCRE
Abstract
(EN)
An ink jet type image forming device comprising a suction fan (11) for sucking from below a platen (12) a print medium (14) that is being conveyed on the platen (12), and a variable control means for variably controlling the suction force of the suction fan (11) according to predetermined conditions. The variable control means has a means that, as a predetermined condition and in each scanning of a head, recognizes presence or absence of the head in a printing region ranging from the printing start position to the printing end position and that controls suction fan such that the suction force is lower when the head is outside the printing region than when it is within the printing region. Alternatively, it has a means that, as a predetermined condition, recognizes the kind of a print medium that has been set and that controls the suction force of the suction fan according to the recognized kind of print medium. Adjustment of the suction force of the suction fan lowers the load on a conveyance motor and generally reduces power consumption and noise.
(FR)
La présente invention concerne un dispositif de formation d'image de type à jet d'encre comprenant un aspirateur (11) pour aspirer par dessous une platine (12) un support d'impression (14) amené sur la platine (12), et un système de contrôle variable pour effectuer un contrôle variable de la force d'aspiration de l'aspirateur (11), en fonction d'états prédéterminés. Le système de contrôle variable comprend un mécanisme qui, dans un état prédéterminé et à chaque balayage de tête, détecte la présence ou l'absence de la tête dans une région d'impression comprise entre la position de début d'impression à la position de fin d'impression. En outre, ce mécanisme contrôle l'aspirateur de sorte que la force d'aspiration soit inférieure lorsque la tête se trouve en dehors de la région d'impression, que lorsqu'elle se trouve dans la région d'impression. Dans une variante, il comprend un mécanisme qui, dans un état prédéterminé, reconnaît le type de support d'impression utilisé et contrôle la force d'aspiration de l'aspirateur en fonction du type de support d'impression reconnu. En l'occurrence, le réglage de la force d'aspiration de l'aspirateur réduit la charge d'un moteur de transport et réduit généralement la consommation d'énergie et le bruit.
