To provide printhead cleaning and treatment systems and methods that address the build-up of ink on a printhead to improve print quality.SOLUTION: A system for cleaning and treating a printhead includes (a) a movable carriage 110 having a cleaning blade 120 and an absorptive pad 125 that are affixed to a base of the movable carriage, (b) a low vapor pressure organic solvent 130 which is deliverable to the absorptive pad via a pump and has a vapor pressure lower than water, and (c) a carriage moving mechanism that moves the carriage so that the cleaning blade and the absorptive pad pass over the printhead 105.SELECTED DRAWING: Figure 1 【課題】印刷品質を改善するために印刷ヘッド上のインクの蓄積に対処する印刷ヘッドの洗浄及び処理システム並びに方法。【解決手段】印刷ヘッドを洗浄及び処理するためのシステムは、（ａ）移動式キャリッジ１１０の基部に、洗浄ブレード１２０と、吸収パッド１２５と、が取り付けられている、移動式キャリッジと、（ｂ）低蒸気圧有機溶媒１３０であって、ポンプを介して、吸収パッドに送達可能であり、水よりも低い蒸気圧を有する、低蒸気圧有機溶媒と、（ｃ）洗浄ブレード及び吸収パッドが印刷ヘッド１０５の上を通過するように、キャリッジを移動させる、キャリッジ移動機構と、を含む。【選択図】図１
