Title
(EN) RECORDING HEAD RESTORATION SYSTEM, INK JET RECORDING APPARATUS PROVIDED WITH SAME, AND RECORDING HEAD RESTORATION METHOD
(FR) SYSTÈME DE RESTAURATION DE TÊTE D'ENREGISTREMENT, APPAREIL D'ENREGISTREMENT À JET D'ENCRE POURVU DE TÊTE D'ENREGISTREMENT ET PROCÉDÉ DE RESTAURATION DE TÊTE D'ENREGISTREMENT
(JA) 記録ヘッドの回復システム及びそれを備えたインクジェット記録装置、並びに記録ヘッドの回復方法
Abstract
(EN) Provided is a recording head restoration system that is capable of cleaning an ink discharge surface while suppressing dripping or sticking of a cleaning liquid to a recording medium. This restoration system for a recording head (17) is provided with: the recording head (17); a cleaning liquid tank (71) that stores a cleaning liquid (23); a liquid supply mechanism (75) that includes a liquid supply pump (72); and a control unit (110). The control unit (110) can carry out a restoration operation of the recording head (17), the operation restoration including: a cleaning liquid supply operation for supplying the cleaning liquid (23) in the cleaning liquid tank (71) to the recording head (17); a wiping-off operation for wiping the ink discharge surface (F1) of the recording head (17) in a state where the cleaning liquid (23) is held by a wiper (35) after the execution of the cleaning liquid supply operation; and a reverse-flow operation for causing the cleaning liquid (23) to reversely flow from the cleaning liquid supply port (60a) of the recording head (17) in a direction toward the cleaning liquid tank (71) by means of the liquid supply mechanism (75) during or after the execution of the wiping-off operation.
(FR) L'invention concerne un système de restauration de tête d'impression qui est apte à nettoyer une surface d'évacuation d'encre tout en supprimant l'égouttement ou l'adhérence d'un liquide de nettoyage à un support d'enregistrement. Ledit système de restauration pour une tête d'enregistrement (17) comprend : la tête d'enregistrement (17) ; un réservoir de liquide de nettoyage (71) qui stocke un liquide de nettoyage (23) ; un mécanisme d'alimentation en liquide (75) qui comporte une pompe d'alimentation en liquide (72) ; et une unité de commande (110). L'unité de commande (110) peut effectuer une opération de restauration de tête d'enregistrement (17), l'opération de restauration comprenant : une opération d'alimentation en liquide de nettoyage, pour alimenter en liquide de nettoyage (23) le réservoir de liquide de nettoyage (71) de la tête d'enregistrement (17) ; une opération d'essuyage, pour essuyer la surface d'évacuation d'encre (F1) de la tête d'enregistrement (17) dans un état dans lequel le liquide de nettoyage (23) est maintenu par un frotteur (35) après l'exécution de l'opération d'alimentation en liquide de nettoyage ; et une opération d'écoulement inverse, pour amener le liquide de nettoyage (23) à s'écouler en sens inverse d'une orifice d'alimentation en liquide de nettoyage (60a) de la tête d'enregistrement (17) dans une direction vers le réservoir de liquide de nettoyage (71), au moyen du mécanisme d'alimentation en liquide (75), pendant ou après l'exécution de l'opération de nettoyage.
(JA) クリーニング液が記録媒体に付着したり落下したりするのを抑制しながら、インク吐出面を清浄化することが可能な記録ヘッドの回復システムを提供する。この記録ヘッド(17)の回復システムは、記録ヘッド(17)と、クリーニング液(23)を収容するクリーニング液タンク(71)と、給液ポンプ(72)を含む給液機構(75)と、制御部(110)と、を備える。制御部(110)は、クリーニング液タンク(71)内のクリーニング液(23)を記録ヘッド(17)に供給するクリーニング液供給動作と、クリーニング液供給動作の実行後、ワイパー(35)によりクリーニング液(23)を保持した状態で記録ヘッド(17)のインク吐出面(F1)を拭く拭き取り動作と、拭き取り動作の実行中又は実行後、給液機構(75)によりクリーニング液(23)を記録ヘッド(17)のクリーニング液供給口(60a)からクリーニング液タンク(71)に向かう方向に逆流させる逆流動作と、を含む記録ヘッド(17)の回復動作を実行可能である。
