摘要： An apparatus for maintaining a recording head which has a nozzle opening in a nozzle-defining surface thereof, and ejects, from the nozzle, a droplet of an ink toward a recording medium, in a state in which the recording head is separate from a remaining portion of a recording device. The apparatus includes a cover member which is adapted to air-tightly contact the recording head to cover the nozzle-defining surface of the recording head such that a space is formed between the cover member and the nozzle-defining surface. The apparatus further includes a selectively communicating device which can selectively take (a) a first state thereof in which the selectively communicating device allows the space to communicate with an atmosphere so that substantially no difference is produced between an air pressure in the space and an atmospheric pressure, when the cover member is air-tightly contacted with the recording head; and (b) a second state thereof in which the selectively communicating device shuts off the communication between the space and the atmosphere, and thereby air-tightly closes the space, after the cover member is air-tightly contacted with the recording head.

摘要： An ink jet printer uses a print head that has at least one ink nozzle and performs printing on a recording medium by ejecting ink from the ink nozzle. An air chamber is connected to the print head to trap air generated in an ink passage. A purge device discharges the air trapped in the air chamber from the ink nozzle. A filter member divides the lower portion of the air chamber into a first chamber and a second chamber. The air chamber traps and stores air in the top portion of the air chamber and the filter member passes ink there through when the print head performs printing. The air trapped in the air chamber is discharged when the purge device generates an ink flow that goes over the filter member.

摘要： An ink jet printer uses an ink tank storing ink to be supplied to a print head, an ink tube, an ink chamber mounted on a carriage to store ink to be supplied from the ink tank to the print head, and a connecting member that includes an ink outflow port connected to the ink chamber and an ink inflow port where ink flows from the ink tube. At an intersection of the ink inflow port and the ink outflow port, a direction of a flow of ink from the ink inflow port is changed. Further at the intersection, a cushion is provided to absorb pressure waves generated in the ink tube on an extended line in an initial direction where ink flows in the ink passage over the intersection.

摘要： An ink accommodating pouch for accommodating ink is produced in the following manner. Two sheets formed of a synthetic resinous material are prepared. Four edges of both the sheets overlap each other and are oriented in the same direction. Three of the aligned edges are fused completely by heat, forming junctions. A resultant product is turned inside out so that the junctions of the three edges are turned inward and protrude inside a pouch. An ink extraction outlet is sealed to the remaining open edge. When the pouch is filled with ink, When the ink accommodating pouch 60 is filled with ink, the sheets near the junctions swell to a protruding curved shape on the outside of the pouch, enabling the pouch to accommodate an increased amount of ink.

摘要： An ink-jet printer in which drive data for a print head is converted into a light signal by a first light-emitting diode provided in a control circuit. The light signal is transmitted, through an optical fiber, to a first photo-diode provided in a receiver circuit. The light signal received by the first photo-diode is converted into an electric signal. Data concerning the status of a print head unit is converted into a light signal by a second light-emitting diode provided in the receiver circuit. The light signal is transmitted from the second light-emitting diode, through the optical fiber, to a second photo-diode provided in the control circuit. The light signal received by the second photo-diode is converted into an electric signal.

摘要： A casing of an ink cartridge is formed with an accommodating chamber for accommodating an ink accommodating pouch and a waste ink introducing chamber into which waste ink from print heads is discharged. A stepped opening formed penetrating through a cover is sealed off with an air permeable film. One end of a labyrinth channel formed in the cover is fluidly connected to the stepped opening outside the air permeable film. Another end of the labyrinth channel is exposed to ambient air through a hole formed in an air non-permeable film that is placed over both the stepped opening and the labyrinth channel.

摘要： An ink-jet printer performs formation of an image by jetting an ink from nozzles of an ink-jet head. When a power supply is switched ON after a time measuring section is not capable of measuring time due to the power supply has been switched OFF, then the ink-jet printer outputs to a display section a signal which causes a display control section, provided on a controller, to display a message asking a user whether or not a cleaning operation by a recovery operation control section is to be performed. Accordingly, any unnecessary operation for recovering the jetting function is reduced, solving problems such as waiting time required for performing the operation for recovering the jetting function and that the ink is consumed unnecessarily.
