摘要:
A head recovery device for an ink jet recording apparatus is provided with a pigment ink discharge port for discharging pigment ink and a dye ink discharge port for discharging dye ink. The device comprises a pigment ink cap for capping the pigment ink discharging port and a dye ink cap for capping the dye ink discharge port, and, in a predetermined recovery operation, a preliminary discharge is executed from the dye ink discharge port to the pigment ink cap.
摘要:
An ink jet recording apparatus comprising a recording head having discharge ports for discharging the ink, an ink tank for storing said ink to be supplied to the recording head, and suction recovery means for stabilizing the ink discharge from the recording head, characterized in that the suction recovery means has a plurality of suction operations, which can be selected in accordance with the content of the discharge stabilization.
摘要:
An ink jet recording apparatus comprises a carriage (2) movable in a given direction with a recording head (1) which is detachably mountable on it and provided with discharge ports for discharging liquid. The apparatus is arranged to include a sensor (21) for detecting the presence or absence of the carriage, the recording head, and at least one of the ink containers. This sensor is provided for the main body of the apparatus and positioned within the movable range of the carriage. With this arrangement, it is possible to simplify the structure required for detecting whether or not these vital elements for recording are installed without any auxiliary power-supply or memory means.
