摘要： An ink jet recovery device comprises an elastic cap that is movable between a retracted position, in which it is spaced from a recording head, and a contact position, in which it is pressed against and seals the recording head. The recovery device also includes a rotatable drive gear having a cam surface, with a retracting cam and a compression cam, for moving the cap. When the drive gear is in a first angular position the retracting cam moves the cap to its retracted position, and when the drive gear is in a second angular position the compression cam presses the cap against the recording head. The drive gear has a third angular position for disengaging the pin from the cam surface so that a spring can press the cap into the contact position. In operation, the compression cam further presses the cap toward the recording in order to force air into the recording head to aid recovery.

摘要： A recovery device for an ink jet recording apparatus having a cup for an ink discharge port of a recording head and a suction device communicating with the cap for sucking ink from the ink discharge port includes a communicating tube, a communicating valve, and a ventilating valve. The communication tube communicates with the cap and a subtank which supplies ink to the recording head. A communicating valve connects and disconnects communication of the cap with the subtank and is provided in an intermediate portion of the tube. A ventilating valve communicates the interior of the tube with the atmosphere and is provided separately from the communicating valve.

摘要： A method of cleaning a discharge port surface of an ink jet recording apparatus includes wiping the surface using a blade having a certain contact area with the surface and rubbing the surface using a rubbing member having a larger contact area with the surface than the blade. The wiping and rubbing operations are performed independently of each other so that their different purposes can be better accomplished. For example, since rubbing the surface need not be done as often as wiping, they can both be performed at optimum intervals. The rubbing member can be removably mounted to a replacement ink cartridge so that the rubbing member can be conveniently replaced at the same time as the cartridge.

摘要： A liquid ejection recording apparatus has a carriage, a liquid ejection recording unit, a lever biased by a spring for mounting the unit on the carriage, and a communication hole portion formed in an ink tank in the unit. When the unit is fixed on the carriage for printing, a projection presses the communication hole portion to provide a communication hole for communicating the interior of the ink tank with the outer atmosphere. Stable ink ejection is guaranteed without clogging of a nozzle or the like and regardless of the amount of ink remaining in the ink tank.

摘要： There is disclosed a method and apparatus for recovering an ink jet head having an opening communicating with a discharge port, the opening being provided on a same planar surface on which the discharge port for discharging ink is provided. An area of the opening is larger than an area of the discharge port. The method includes the steps of forcibly introducing gas into the ink jet head simultaneously through the discharge port and the opening, and exhausting the gas introduced into the ink jet head in the introducing step with ink through the discharge port. The gas introduced into the ink jet head enables the ink to be exhausted at an increased velocity in the exhausting step.
