Abstract
An ink supply system for an ink printer. The system includes an ink cartridge which supplies ink through a conduit to the print head of the printer. A bubble trapping device is disposed along the conduit and includes a porous member which prevents air bubbles from entering the nozzle of the print head. The air bubbles are held in a chamber defined in the bubble trapping device. Fluid passages in the chamber of the bubble trapping device allow for continuous feeding of the ink to the porous member for passage to the nozzle. A bubble detecting device may also be provided in the supply system.
