  • Patent number: 10369794
    Abstract: As first determination processing, a CPU of a printer determines whether a temperature T, which is based on an input value from a temperature detector, is higher than a reference temperature Tw. In a case where the CPU has not determined, in the first determination processing, that the temperature T is higher than the reference temperature Tw, the CPU, after cover processing and without performing soak processing, performs first cap processing, which puts a nozzle face into a state in which it is not soaked by a cleaning liquid. In a case where the CPU has determined, in the first determination processing, that the temperature T is higher than the reference temperature Tw, the CPU, after the cover processing, performs the soak processing, which supplies the cleaning liquid to a cap, thus putting the nozzle face into a state in which it is soaked by the cleaning liquid. The possibility that a discharge failure will occur in a nozzle of the printer is therefore reduced.

  • Patent number: 10022969
    Abstract: A print device includes a head, a recovery portion, a processor, and a memory. The head is configured to eject a first ink for base printing and a second ink for image printing. The first ink is ejected onto a print medium and the second ink is ejected on the base printing to print image printing. The recovery portion is configured to perform recovery processing. The recovery processing recovers an ejection performance of the first ink of the head. The memory stores computer-readable instructions. When the computer-readable instructions are executed by the processor, the processor acquires an integrated value of an ejection amount of the first ink. And the processor also determines, based on the acquired integrated value, whether to perform the recovery processing by the recovery portion.
