  • Patent number: 8376505
    Abstract: A media processing device, control method therefor, and associated program prevent a drop in the throughput of a media production process due to cleaning the print head. A publisher has a media drive, a transportation unit that conveys a recording medium according to a transportation command received from a host, and a printer that discharges ink from the nozzles of a print head to print on the label side of the recording medium. The printer also applies a cleaning process to the print head according to an internal signal that is generated when the transportation command or a data write command is received from a host. The cleaning process is executed while the media is conveyed.

  • Patent number: 8376543
    Abstract: An apparatus includes a guide unit configured to guide surfaces of a sheet, which is conveyed after passing through a recording unit, with respect to a vertical direction, the guide unit having an interval variable in the vertical direction, and a correction mechanism for correcting skew of the sheet, which is inserted into the guide unit, by pushing the sheet from both sides thereof in a sheet width direction. The interval of the guide unit in the vertical direction widens when the sheet is cut compared with that when correction is executed by the correction mechanism, and when the sheet is cut, conveyance of the sheet is temporarily stopped in a position of the cutter. In cutting, a loop of the sheet is formed on the guide unit the interval of which in the vertical direction has widened.

  • Patent number: 8220896
    Abstract: A system and method to provide pressure to de-prime a printhead. An image forming device comprises an ink reservoir that contains ink and provides the ink to a printhead. When a fault condition is detected that indicates a likelihood of a solidifying of the ink, the printhead is de-primed by applying pressure to the printhead to purge the ink from the printhead. The fault condition comprises any of a loss of power, a power-down process, or a printhead temperature being less than or equal to a threshold temperature.

  • Publication number: 20120162309
    Abstract: A particle removal device for an ink jet printer is discussed. The particle removal device includes a first separator comprising an arrangement of obstacles including at least two rows of obstacles that extend laterally with respect to a flow path of ink in the first separator. The rows of obstacles are offset from one another by a row offset fraction. The arrangement of obstacles is configured to preferentially route larger particles having diameters greater than a critical diameter through the arrangement and along a first trajectory vector that is angled with respect to the direction of the flow path of the ink. The angle of the first trajectory vector with respect to the ink flow path is a function of the row offset fraction. Smaller particles having diameters less than the critical diameter travel through the arrangement along a second trajectory vector that is not substantially angled with respect to the flow path of the ink.

  • Patent number: 8205972
    Abstract: An image forming apparatus includes a recording head having a nozzle surface in which a plurality of nozzles is formed; and a vibration generating mechanism which is arranged at a position away from a recording medium in a moving direction of a recording head, and which intermittently sucks or blows air from and to the nozzle surface of the recording head moved to the position. The vibration generating mechanism vibrates a meniscus of a liquid inside each of the nozzles. Accordingly, there is provided an image forming apparatus in which the liquid is not consumed unnecessarily and thus is economical, and which effectively facilitates maintenance and recovery of the jetting function of the nozzles.

  • Patent number: 8201917
    Abstract: An inkjet recording apparatus may include a flow path unit including a discharge port, an actuator configured to supply discharge energy and non-discharge energy to the ink, a drive controller configured to cause the actuator to supply the discharge energy, and a cap moving unit configured to move a cap between the open position and the covering position. After the supply of the image data is started, the drive controller may cause the actuator to supply the non-discharge energy in both a first period and a second period. The first period begins at starting of the supply of the non-discharge energy. The second period begins at the end of the first period and ends when the supply of the discharge energy is started. A frequency of the supply of the non-discharge energy during the first period is greater than that of the non-discharge energy during the second period.
