摘要： An ink jet recording head is provided with a nozzle formation face on which nozzles for ejecting ink drops in accordance with print data are formed. A capping member for sealing the nozzle formation face has an inner space formed with a bottom. An ink absorbing member is provided on the bottom of the inner space. In a first flushing mode, ink drops are ejected into the capping member in a state that the nozzle formation face is sealed by the capping member. In a second flushing mode, ink drops are ejected into the capping member in a state that the capping member is separated from the nozzle formation face. Either the first flushing mode or the second flushing mode is selectively performed.

摘要： A capping member for an ink jet recording head is composed of a cap which is to be brought into contact with a surface of the recording head provided with nozzle orifices, and a cap case for holding the cap. A passage communicating an internal space defined by the cap with a suction hole connected to a suction pump and a passage communicating the internal space with an air hole connected to the outside are respectively formed into a specific shape so as to inhibit vaporization of an ink solvent in the internal space. A tube made of an elastic and restorative material is used for a tube connected to the suction pump. A tube made of a material having high gas-barrier characteristic is used for a tube connected to the capping member. Both of the tube is connected with each other by a connecting member in order to inhibit vaporization of an ink solvent from the tubes. Accordingly, the reliability of printing operation when printing is restarted after the long-term halt of the ink jet recording head is remarkably enhanced. The cap may be formed by fitting into a groove formed on a brim portion of the cup-shaped cap case having high rigidity. Therefore, elasticity of the cap can be controlled by the height thereof and can be deformed uniformly for whole periphery of the brim portion to attain high airtightness of the cap.
摘要翻译：用于喷墨记录头的封盖构件由与被设置有喷嘴孔的记录头的表面接触的盖和用于保持盖的盖壳构成。将由帽限定的内部空间与连接到抽吸泵的抽吸孔和连通内部空间的通路与连接到外部的空气孔连通的通道分别形成为特定形状，以抑制油墨溶剂的蒸发在内部空间。由弹性和修复材料制成的管用于连接到抽吸泵的管。使用与封盖构件连接的管，由具有高阻气特性的材料制成的管。两个管通过连接构件相互连接，以阻止墨溶剂从管中汽化。因此，在喷墨记录头的长时间停止之后打印重新开始时的打印操作的可靠性显着提高。帽可以通过装配到形成在具有高刚性的杯形帽壳的边缘部分上的凹槽中而形成。因此，帽子的弹性可以通过其高度来控制，并且可以在边缘部分的整个周边均匀地变形，以获得盖子的高气密性。
