Abstract
【解決手段】そのプリンタノズルから所定時間内に吐出されたインク滴の個数及び同時間内にそのインクスティック送給系内の所定点を通過したインク量に基づき吐出されたインク滴の平均サイズを求め、求めた平均サイズが所定インク滴サイズ条件に合致していない場合はノズル作動信号を修正してインク滴サイズを変化させる。通過インク量は、所定点を通過したインクスティック30又はその仮想片の個数を機械アーム式又はサーミスタ式の計数機構で計数して検知する。例えば、インクスティック30の外面に被検知部150を設け、インクスティック30における被検知部形成部位断面積と他部位断面積との違いにより熔融板32Dで生じる温度変化をサーミスタ210,222で検知する。
