Title (EN) LINE-SCANNING TYPE INK JET RECORDER
(FR) IMPRIMANTE A JET D'ENCRE DE TYPE A BALAYAGE EN LIGNE
Abstract:
(EN) With a recording head (200) having a plurality of nozzle holes arranged in a row in a first direction disposed so that the nozzle holes face a recording element (P), the recording element (P) is moved for main scanning in a second direction (B) with respect to the recording head (200). Ink particles jetted from the nozzle holes are charged to a charging level corresponding to the deflection distance of the ink particles, and the charged ink particles are deflected in a direction perpendicular to the main scanning line. In addition, a plurality of ink particles jetted from the plurality of nozzle holes are allowed to strike the same pixel position or a portion in the vicinity thereof to enable multiple-striking to the same pixel position or a portion in the vicinity thereof, thereby easing back-up for failed nozzles and uneven recording.
(FR) Doté d'une tête d'impression (200) présentant une pluralité de trous de buses disposés en une rangée orientée dans une première direction de telle sorte qu'ils se trouvent face à un support d'impression (P), ce support d'impression (P) est déplacé pour le balayage principal dans une deuxième direction (B) par rapport à la tête d'impression (200). Des particules d'encre provenant des trous de buses sont chargées à un niveau de charge correspondant à la distance de déflexion des particules d'encre et les particules d'encre chargées sont déviées dans une direction perpendiculaire à la ligne de balayage principal. En outre, une pluralité de particules d'encre provenant de la pluralité de trous de buses peut frapper la même position de pixel ou une zone proche de celle-ci pour permettre une frappe multiple de cette même position de pixel ou d'une zone proche de celle-ci, facilitant ainsi la compensation du fonctionnement défaillant de certaines buses et d'une impression irrégulière.
