  • Patent number: 10328691
    Abstract: A print head has a jet stack, a jet stack heating and temperature measuring element thermally connected to the jet stack, the jet stack heating and temperature measuring element including: a first, etched copper layer having heat spreading characteristics and including a resistive heat source electrically connected in series to a voltage source and a switch; an electrically insulative on a back side of the first copper layer; and a second, etched copper layer on a side of the electrically insulative layer opposite the first copper layer, the second copper layer having a temperature sensing element to sense a temperature of the print head without a thermistor, the temperature sensing element connected in series with a voltage source and a transistor. A print head may use a thermistor but the heat spreading layer eliminates the need for a heat sink to attach to the print head.

  • Patent number: 10220614
    Abstract: An inkjet printhead including an inkjet configured to eject drops of ink in response to receiving an electrical signal, a memory configured to store image data, and a processor operatively coupled to the inkjet and the memory. The processor receives the image data and determines a period of latency of the inkjet printhead. When the period of latency is within a predetermined timeframe, the processor increases a voltage of the electrical signal to a second voltage for an initial number of drops to eject the drops of ink in a pattern of printed ink drops with reference to at least a portion of the image data and reduce the voltage of the electrical signal after the initial number of drops to eject drops of ink in a pattern of printed ink drops with reference to a remaining portion of the image data, and generates the electrical signal.
