Embodiment Construction

[0045] Reference will now be made to embodiments of the invention, examples of which are illustrated in the accompanying drawings, in which like reference numerals refer to like parts. In order to explain the present invention, the following description refers to the figures.

[0046] An inkjet printer is a device that ejects tiny ink droplets at a predetermined position on a printing medium (eg, paper, fabric, etc.) to print a predetermined image on the surface of the printing medium. FIG. 1 is an exploded perspective view of an ink cartridge 100 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1 . Referring to FIGS. 1 and 2 , an inkjet printer includes an ink cartridge 100 that stores ink and ejects the stored ink through a printhead 150 . In an exemplary embodiment of the present invention, the ink cartridge 100 is provided in an array head type inkjet printer, and is provided with a plurality of print he...

Abstract

An ink cartridge of an inkjet printer includes at least one ink tank, at least one negative pressure adjusting part, an ink channel unit, and at least one print head having nozzles, wherein the ink channel unit is surface-treated by an ion assisted reaction (IAR) before being assembled.

Description

technical field [0001] The present invention relates to an ink cartridge usable in a printing device such as an inkjet printer, and more particularly, to an ink cartridge that prevents ink passages from being clogged by air bubbles, and a manufacturing method thereof. Background technique [0002] Generally, an inkjet printer ejects tiny ink droplets at a predetermined position on a printing medium (such as paper, fabric, etc.), so as to print an image of a predetermined specific color on the surface of the printing medium. [0003] A conventional inkjet printer includes an ink cartridge that reciprocates in a direction perpendicular to a conveying direction of a printing medium (eg, printing paper), that is, in a width direction of the printing paper, thereby printing a predetermined image. However, the conventional inkjet printer in which the ink cartridge is reciprocated as described above to print a predetermined image has a disadvantage in that the printing speed is slo...
