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.
