Summary: | To provide a head system, a liquid discharge device and a liquid discharge method which can improve printing speed.SOLUTION: A head system comprises: a main control circuit which has a first counter; and a plurality of head modules having nozzles. Each of the plurality of head modules includes a sub control circuit having a second counter. The main control circuit and each sub control circuit are serially connected to each other via a communication cable. The main control circuit executes processing of transmitting an image signal to each sub control circuit via the communication cable. Each sub control circuit, when the conveyance speed of the recording medium recorded by the liquid discharged from the nozzle is equal to or greater than a prescribed speed, executes first discharge processing of causing the nozzle of the head module connected thereto to discharge the liquid every time the second counter included therein shows a counter value indicating the lapse of a first prescribed period.SELECTED DRAWING: Figure 6
【課題】印刷速度を向上させることができるヘッドシステム、液体吐出装置及び液体吐出方法を提供する。【解決手段】ヘッドシステムは、第1カウンタを有する主制御回路と、ノズルを有する複数のヘッドモジュールとを備え、前記複数のヘッドモジュールそれぞれは、第2カウンタを有する副制御回路を備え、前記主制御回路と、前記各副制御回路とが通信ケーブルを介して直列的に接続され、前記主制御回路は、前記通信ケーブルを介して前記各副制御回路に画像信号を送信する処理を実行し、前記各副制御回路は、前記ノズルから吐出された液体によって記録される記録媒体の搬送速度が所定速度以上である場合、自身が有する前記第2カウンタが第1所定周期の経過を示すカウンタ値になる都度、自身が接続された前記ヘッドモジュールの前記ノズルから液体を吐出させる第1吐出処理を実行する。【選択図】図6 |
