Abstract
An ink tank for an inkjet printing device that includes a housing for containing ink, first and second chambers within the housing, and a partition separating the first and second chambers. The ink tank also includes a communication port connecting the first chamber in fluid communication with the second chamber, a tank outlet disposed within a wall of the housing, and a high capillary pressure producing member in direct communication with the outlet. The ink tank may be configured such that the ink may flow from the free ink space through the capillary pressure producing member and exit the outlet without having to travel through the communication port.
