摘要： The invention has been made to prevent ink adhesion or an ink discharge failure caused by ink adhesion due to evaporation of volatile components of ink which occurs when the ink receptor of a printhead is exposed to air for a long time. If an inkjet printhead and an ink tank containing ink to be supplied to the printhead are attached to a carriage, the ink supply port of the ink tank is pressed to the ink receptor of the printhead. In this arrangement, the presence/absence of attachment of the ink tank to the carriage is detected. If it is detected that the ink tank is not attached to the carriage, a suction operation for the printhead is performed and controlled to suck out ink from the nozzles of the printhead.
摘要翻译：本发明是为了防止由于打印头的油墨接收器长时间暴露于空气而发生的油墨易挥发成分的挥发而引起的油墨附着或墨水排出故障。如果将喷墨打印头和含有要供应到打印头的墨水的墨水盒连接到滑架上，则墨水盒的墨水供给口被压到打印头的墨水接收器上。在这种布置中，检测到墨盒是否存在于托架上。如果检测到墨水罐没有附接到滑架上，则执行打印头的抽吸操作并被控制以从打印头的喷嘴吸出墨水。
