  • System for transporting phase change ink using a thermoelectric device
    Patent number: 8721057
    Abstract: An ink transport system for a phase change ink printer has been developed that enables accurate control of refilling a second ink reservoir from a first ink reservoir with minimal moving parts. The system includes a thermoelectric device that is operatively connected to a thermally conductive tube, which fluidly connects the first and second ink reservoirs. The thermoelectric device is operated by a controller to heat phase change ink in the thermally conductive tube and enable flow of ink from the first reservoir to the second reservoir, and to remove heat from the phase change ink in the thermally conductive tube to solidify ink in the tube and disable flow of ink from the first reservoir to the second reservoir.

  • Printing system with selective heater activation to enable ink flow to a printhead in the printing system
    Patent number: 8556398
    Abstract: A method for operating a printer having multiple printheads includes activating a heater that is operatively connected to a printhead that ejects ink having a single color in response to receiving a print job. The printer detects the presence of colors other than the single color in image data received in the print job, and activates heaters operatively coupled to printheads that eject ink drops that correspond to the detected colors.
