ABSTRACT:
A liquid cartridge includes an ink cartridge having a first housing portion for containing a liquid and a waste liquid storage cartridge having a second housing portion for containing a waste liquid, and a rewritable nonvolatile storage portion which stores a first threshold, a second threshold, liquid amount information and waste liquid amount information. The first threshold indicates a near liquid end state in which the liquid in the first housing portion is near to end. The second threshold indicates a near full state in which the waste liquid in the second housing portion is near to full. The liquid amount information indicates a liquid amount of the liquid contained in the first housing portion. The waste liquid amount information indicates a waste liquid amount of the waste liquid contained in the second housing portion. The ink cartridge and the waste liquid cartridge are integrally formed.
