  • Patent number: 10947073
    Abstract: In some examples, velocity and torque based media motor control may include ascertaining a velocity and torque for a feed roller motor associated with a feed roller, and ascertaining a velocity and torque for a drive roller motor associated with a drive roller that is to receive media from the feed roller. Further, velocity and torque based media motor control may include determining whether the torque for the drive roller motor is greater than a torque target. In response to a determination that the torque for the drive roller motor is greater than the torque target, the torque for the drive roller motor may be reduced to the torque target, and the torque for the drive roller motor may be maintained at the torque target.

  • Patent number: 8544992
    Abstract: A fluid cartridge for a printing device includes a housing including a floor, a chamber defined in the housing and configured to store an ink therein, a capillary medium disposed in the housing and in operative communication with the chamber, and a wick disposed at least partially in an opening of the floor, the wick including a portion extending a predetermined distance into the housing such that the wick portion contacts the capillary medium. The fluid cartridge further includes an enriched pigment-confining member established inside the housing such that the confining member physically contacts the floor and surrounds at least a portion of a periphery of the wick. The confining member is configured to i) block enriched ink from the wick, and/or ii) dilute the enriched ink prior to flowing through the wick.

  • Patent number: 8172348
    Abstract: A print head cap includes a vent which is opened during storage of the print head against the cap, is closed during priming of fluid through nozzles of the print head and is opened to stop the priming. Pumping of fluid from the cap is started substantially immediately upon opening of the vent to stop priming.
