Droplet deposition apparatus, in which the capacitance of walls of dummy chambers in the printhead is used to provide an indication of the temperature of the droplet fluid to enable the magnitude of the actuating electrical signals applied to the actuable walls of the fluid ejection chambers to be adjusted.
La présente invention concerne un appareil de dépôt de gouttelettes dans lequel on utilise la capacitance de parois d'enceintes muettes, disposées dans la tête d'impression, afin d'obtenir une indication de la température du fluide, ce qui permet d'ajuster la grandeur des signaux électriques d'actionnement des parois manoeuvrables des chambres d'éjection de fluide.
