Abstract
A method is provided for judging whether an ink-containing medium which is used for absorbing an ink is applicable to an ink cartridge. The method includes steps of (a) getting a first value A of a physical parameter of the ink-containing medium, (b) immersing the ink-containing medium into an ink container containing the ink under an immersion temperature for an immersion time, (c) washing the ink-containing medium, (d) drying the ink-containing medium under a dry temperature and a dry pressure, (e) getting a second value B of the physical parameter of the ink-containing medium, (f) calculating a relative change of the physical parameter of the ink-containing medium from the values of the physical parameters of the ink-containing medium, and (g) rejecting the ink-containing medium when the relative change of the physical parameter of the ink-containing medium is larger than a specific value.
