INK CARTRIDGE HAVING INNER CONTAINER AND PROCESSING METHOD THEREFOR

An ink cartridge having an inner container and a processing method therefor, the processing method comprising the following steps: removing the top cover of an original ink cartridge to obtain an ink cartridge housing (1); electrically connecting an externally provided control circuit board (3) to the original control circuit board (2) of the original ink cartridge so that the contact point on the original control circuit board (2) communicates with the externally provided control circuit board (3); providing a built-in control circuit board (5) at the location that corresponds to an inner container (4); installing the inner container (4) inside of the ink cartridge housing (1) so that an inner contact point (5a) of the built-in control circuit board (5) of the inner container (4) is electrically connected to the externally provided control circuit board (3) for conduction to obtain the ink cartridge having an inner container; and writing the actual ink amount data and program used for the inner container (4) into a first chip of the externally provided control circuit board (3) or into a second chip of the built-in control circuit board (5). For the described ink cartridge having an inner container, by means of replacing the inner container (4), the ink cartridge housing (1) may be used repeatedly to save resources; and a printer can acquire the actual amount of ink inside of the ink cartridge having an inner container.
