    Abstract: An extraction pump of a printing device fluidically connected to a reservoir of the printing device is set to a specified rotational velocity. A pulse-width modulation (PWM) value of the extraction pump correspondingly increases until the extraction pump rotates at the specified rotational velocity. While the power of the extraction pump is monitored, a power of a supply pump of the printing device fluidically connected between the extraction pump and the reservoir is continually increased; the power of the extraction pump correspondingly decreases to maintain rotation of the extraction pump at the specified rotational velocity. Responsive to the power of the extraction pump decreasing to a characterized value for the specified rotational velocity, the power of the supply pump ceases being increased.

    Abstract: An inlet seal, an outlet seal, and a piston are connected to a shaft. The inlet seal seals an ink inlet of an ink reservoir. The outlet seal seals an ink outlet of the ink reservoir. Also, the piston is within a cylinder. The inlet seal, the outlet seal, and the piston all move with the shaft. A biasing member contacts the piston to bias the piston in a first direction. Pressurized air simultaneously provided to the cylinder and to the ink reservoir biases the piston in a second direction, opposite the first direction, and pressurizes ink within the ink reservoir. Moving the shaft in the first direction does not seal the ink inlet but does seal the ink outlet. Moving the shaft in the second direction seals the ink inlet but does not seal the ink outlet, thus allowing the pressurized ink out from the ink reservoir.

  • Patent number: 11110704
    Abstract: According to an example, a printing apparatus may include two drop ejecting elements, a fluid circulating element, and a logic device. The logic device may determine whether one or both of a first drop ejecting element and a second drop ejecting element have been fired within a predetermined period of time prior to a current time. In response to the determination, the logic device may selectively transmit an output signal that is to cause the fluid circulating element to be selectively fired, in which the fluid circulating element is positioned to circulate fluid adjacent to both the first drop ejecting element and the second drop ejecting element.
