To provide a dross extraction system for a printer to provide longer printing times and higher throughput without interruption due to defects or disadvantages associated with dross accumulation.SOLUTION: A dross extraction system includes an ejector 104 defining an associated internal cavity 132, and the internal cavity holds liquid printing material 126. The dross extraction system also includes an inlet 120 coupled to the internal cavity and a conduit external to the ejector and having a distal opening, the conduit positionable so as to contact the liquid printing material and draw the dross into the conduit, thereby extracting the dross from the liquid printing material when negative pressure is applied between the internal volume of the conduit and the dross.SELECTED DRAWING: Figure 1 【課題】ドロスの蓄積に伴う欠陥又は不利益による中断なしに、より長い印刷時間及びより高いスループットを提供するためのプリンタ用ドロス抽出システムを提供する。【解決手段】ドロス抽出システムは、関連付けられた内部空洞１３２を画定しているエジェクタ１０４を含み、この内部空洞が液体印刷材料１２６を保持する。ドロス抽出システムはまた、内部空洞に結合された入口１２０と、エジェクタの外部にあり、遠位開口部を有する導管であって、液体印刷材料に接触して導管の中にドロスを引き寄せるように位置決め可能であり、それによって、導管の内部容積とドロスとの間に負圧がかけられるとき、液体印刷材料からドロスを抽出する、導管とを含む。【選択図】図１
