  • Patent number: 10195854
    Abstract: A print device includes a processor and a memory. The memory storing computer-readable instructions which, when executed by the processor, perform processes. The processes include covering processing controlling a cap into a covering state in which the cap covers a nozzle. The processes include first purge processing purging, in a state in which the cap is in the covering state and a supply valve is closed, an ink from the nozzle by operating a pump at a first rotation speed. The processes include injection processing injecting, after the first purge processing and in a state in which the cap is in the covering state and the supply valve is open, the cleaning liquid into the interior of the cap by operating the pump at a second rotation speed to cause the cleaning liquid to soak a nozzle face.

  • Patent number: 9878542
    Abstract: A print device includes a processor, and a memory. The processor performs processes. The processes include a covering control processing controlling the cap into a covering state in which the cap covers the nozzle. The processes include supply processing supplying, after the covering control processing, the cleaning liquid to the cap from the supply flow path. The processes include hold processing holding, after the supply processing and in a state in which the cleaning liquid has soaked the nozzle face, the cleaning liquid in the cap. The processes include first determination processing determining, after the hold processing, whether a print request has been received. The processes include discharge processing discharging, in a case where a power on signal has been detected or in a case where the first determination processing has determined that the print request has been received, the cleaning liquid that has been held in the cap.
