Title
(EN) PRINTHEAD HAVING A REMOVABLE NOZZLE PLATE
(FR) TETE D'IMPRIMANTE AVEC PLAQUE D'INJECTION DEPOSABLE
Abstract
(EN)
A printhead and method of printing are provided. The printhead has a body with portions of the body defining a fluid chamber and a nozzle orifice. The nozzle orifice is in fluid communication with the fluid chamber. A drop forming mechanism is operatively associated with the nozzle orifice of the body. A plate is removably positioned over the body and has at least one orifice with the at least one orifice being in fluid communication with the nozzle orifice of the body.
(FR)
Cette invention concerne un tête d'imprimante et un procédé d'impression. La tête d'imprimante possède un corps dont certaines parties définissent une chambre pour fluide et un orifice calibré d'injection. Cet orifice calibré est en communication fluidique avec la chambre de fluide. Un mécanisme de formation des gouttes est associé fonctionnel à l'orifice calibré d'injection du corps. Une plaque montée amovible sur le corps présente au moins un orifice calibré, dont au moins un est en communication fluidique avec l'orifice d'injection du corps.
