  • Patent number: 9802420
    Abstract: A method and a device for detecting ink leakage during a printing process are used in an inkjet printing machine including a workflow system on a computer for print job control, an ink supply unit including an ink reservoir with an ink level sensor, a control unit running software for controlling the ink supply and print heads capable of creating ink drops of different sizes. A theoretical amount of ink to be consumed is calculated based on prepress printing data by adding drop volumes using the workflow system. The theoretical amount to be consumed is transmitted to the ink supply control software using the workflow system. An actual amount of ink having been consumed is detected by the ink level sensor. The theoretical ink consumption amount and the actual ink consumption amount are compared and a leakage alert is displayed if the actual amount is greater than the theoretical amount.

  • Patent number: 9770917
    Abstract: Provided is a liquid injecting apparatus equipped with a liquid injecting head, which is mounted on a carriage and moved reciprocally in a widthwise direction of a target, and a valve unit, which is mounted on the carriage to be supplied with liquid via a supply passage from a liquid retainer and to supply liquid to the liquid injecting head. The valve unit has a pressure chamber connected to the liquid retainer via the supply passage; a valve, which opens or closes the supply passage to supply liquid to the pressure chamber; and a flexible film member, which is displaced based on a negative pressure generated as liquid in the pressure chamber decreases to thereby operate the valve.
