Abstract

Une imprimante à jets d'encre comporte un élément de commande déclenché par impulsion 15, 16 qui produit des augmentations de pression dans une chambre à encre 17 d'une tête d'impression à jets d'encre 4 pour provoquer l'éjection de gouttelettes d'encre. Un circuit de contrôle 23 génère des impulsions de commande 33 destinées à l'élément de commande 15, 16 dont la durée est telle que l'élément de commande 15, 16 est maintenu à l'état commandé pendant une durée suffisante pour que la diminution de pression résultant du retour de l'élément de commande 15, 16 tende à compenser une fluctuation de pression produite dans l'encre à la suite du mouvement de commande initial de l'élément de commande 15, 16. L'invention contribue à réduire l'aspiration intempestive de bulles d'air par la buse de sortie en direction de la chambre à encre 17.
