Abstract
A fluid cartridge, such as a cartridge for filling with ink for use in ink jet printhead includes a wick chamber that has outer walls, and forms a wick chamber and a fluid chamber. The outer walls of the fluid chamber are formed to provide no fluid communication with the fluid chamber except through the wick chamber. The ink fluid cartridge is filled by evacuating gas from the ink chamber and from the wick chamber, and then supplying ink into the wick chamber until the ink substantially saturates the wick material, and flows into the ink chamber.
