Abstract
An ink-jet cartridge includes a cartridge body forming an ink reservoir, a standpipe coupled to one side of the ink reservoir, a printhead formed under an ink supply passage formed by the standpipe, through which ink from the ink reservoir is ejected onto a printing medium in a droplet shape, and a filter which covers a top portion of the standpipe. The filter is formed in a convex shape protruding toward the printhead. Ink particles and bubbles flowing from the ink reservoir to the printhead are filtered out, bubbles which may flow from the printhead to the ink reservoir, move to edges of the filter, and the ink is smoothly supplied to the printhead.
