  • Publication number: 20240017553
    Abstract: An example printing device includes a plurality of printing agent reservoirs and a printing assembly that is to emit printing agent onto print media. In addition, the printing device includes a pumping assembly fluidly coupled between the plurality of printing agent reservoirs and the printing assembly. The pumping assembly includes a motor and is to transport the printing agent from the plurality of printing agent reservoirs to the printing assembly. Further, the printing device includes a controller coupled to the motor. The controller is to: receive a work parameter of the motor; receive printing agent usage data; and determine that a first printing agent reservoir of the plurality of printing agent reservoirs is empty based on the work parameter and the printing agent usage data.

  • Patent number: 11467017
    Abstract: An example of an apparatus is provided. The apparatus includes a current source. The apparatus includes a conductor in electrical communication with the current source and a conductive fluid in a reservoir. The apparatus includes a first sensing rod to extend into the reservoir, wherein the first sensing rod has a first diameter. The apparatus includes a tip disposed at an end of the first sensing rod to interact with a surface of the conductive fluid. The tip has a second diameter over a first portion of the tip adjacent to the first sensing rod. The second diameter is smaller than the first diameter. The apparatus includes a sensor to detect an electrical signal between the conductor and the first sensing rod.

  • Publication number: 20220219460
    Abstract: In one example, a print substance detector can include a sensor pin, an actuator coupled to the sensor pin to adjust a distance between a surface of the sensor pin and a base portion of a print substance reservoir, and a controller to send instructions to the actuator to adjust the distance of the sensor pin based on an indication of an operation associated with the print substance reservoir.

  • Patent number: 11267254
    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.
