    摘要: An ink cartridge includes a residual ink sensing unit having a simple structure of an upper electrode plate and a lower electrode plate to accurately detect a capacitance between the upper and lower electrode plate. Therefore, data of a remaining amount of ink is reliably measured, there is less possibility that an ink bag is damaged when the residual ink sensing unit is installed in the ink bag, and damage to the ink cartridge and defective printing due to unstable supply of ink and the missing of the time for replacing the ink cartridge are prevented.
