Title (EN) IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING SAME
(FR) APPAREIL DE FORMATION D'IMAGE ET SON PROCÉDÉ DE COMMANDE
(JA) 画像形成装置及びその制御方法
Abstract:
(EN) The present invention addresses the problem of providing an image forming apparatus and a method for controlling the same that appropriately perform ejection droplet amount adjustment and ejection direction measurement for a plurality of liquid ejection heads arranged along a conveyance direction of a recording medium. The above problem is solved by the image forming apparatus provided with a chart forming control unit that causes a conveyance unit to convey a recording medium at a second conveyance speed slower than a first conveyance speed during image formation and causes a liquid to be ejected from a plurality of ejection elements of one liquid ejection head to form a chart on the recording medium, wherein Vh ≤ D × f/1000 is satisfied when a diameter of dots formed on the recording medium by the liquid ejected from the ejection elements is D[μm], an ejection frequency of the liquid of the ejection elements at the time of forming the chart is f[kHz], and the second conveyance speed is Vh[m/s].
(FR) La présente invention aborde le problème de la fourniture d'un appareil de formation d'image et son procédé de commande qui effectuent de manière appropriée un réglage de quantité de gouttelettes d'éjection et une mesure de direction d'éjection pour une pluralité de têtes d'éjection de liquide disposées le long d'une direction de transport d'un support d'enregistrement. Le problème ci-dessus est résolu par l'appareil de formation d'image pourvu d'une unité de commande de formation de graphique qui amène une unité de transport à transporter un support d'enregistrement à une seconde vitesse de transport plus lente qu'une première vitesse de transport pendant la formation d'image et amène un liquide à être éjecté à partir d'une pluralité d'éléments d'éjection d'une tête d'éjection de liquide pour former un graphique sur le support d'enregistrement, où Vh ≤ D × f/1000 est satisfait lorsqu'un diamètre de points formés sur le support d'enregistrement par le liquide éjecté à partir des éléments d'éjection est D [μm], une fréquence d'éjection du liquide des éléments d'éjection au moment de la formation du graphique est f [kHz], et la seconde vitesse de transport est Vh [m/s].
(JA) 記録媒体の搬送方向に沿って配置された複数の液体吐出ヘッドについて、吐出滴量調整及び吐出方向測定を適切に行う画像形成装置及びその制御方法を提供する。搬送部により記録媒体を画像形成時の第1搬送速度よりも遅い第2搬送速度で搬送させ、かつ1つの液体吐出ヘッドの複数の吐出素子から液体を吐出させて、記録媒体にチャートを形成するチャート形成制御部を備え、吐出素子から吐出される液体によって記録媒体に形成されるドットの径をD[μm]、チャートを形成する際の吐出素子の液体の吐出周波数をf[kHz]、第2搬送速度をVh[m/s]とすると、Vh≦D×f/1000を満たす画像形成装置によって上記課題を解決する。
