Summary:To provide a system and method to attenuate drying of aqueous inks in a printhead.SOLUTION: An environmental conditioner 60 in an aqueous inkjet printer conditions a print zone in the printer so that aqueous ink at nozzles of printheads maintains its low viscosity state and does not dry. The environmental conditioner includes a humidifying chamber 204 having a reservoir configured to contain a volume of water, a heater 208 configured to heat the water in the water reservoir 220 to a predetermined temperature range, an air inlet 212 to move air into the humidifying chamber, an air discharge 216 configured to remove humidified air from the humidifying chamber and direct the humidified air into a space between a faceplate of a printhead and a path for media passing by the faceplate of the printhead. The chamber can include an ultrasonic atomizer to produce a moisturized mist to be absorbed by the heated air or wicking material to transfer moisture to the air.SELECTED DRAWING: Figure 2A 【課題】印刷ヘッド内の水性インクの乾燥を軽減するシステム及び方法を提供する。【解決手段】水性インクジェットプリンタ内の環境調整装置６０は、印刷ヘッドのノズルで水性インクが低粘度状態を維持して乾燥しないように、プリンタ内の印刷ゾーンを調整する。環境調整装置は、ある体積の水を収容するように構成されたリザーバを有する加湿チャンバ２０４と、水リザーバ２２０内の水を所定の温度範囲まで加熱するように構成されたヒータ２０８と、空気を加湿チャンバ内に移動させるための空気入口２１２と、加湿チャンバから加湿空気を取り出し、印刷ヘッドの面板と、印刷ヘッドの面板の傍を通る媒体の経路との間の空間内に加湿空気を方向付けるように構成された空気排出部２１６と、を含む。チャンバは、空気に水分を移送するために、加熱空気又は吸い上げ材料によって吸収される加湿ミストを生成するための超音波霧化器を含むことができる。【選択図】図２Ａ
