Abstract
The invention provides for an ink cartridge unit for an inkjet printer. The cartridge includes an elongate main body defining a number of rectangular ink reservoirs along a length thereof, with end reservoirs being larger than reservoirs interposed between the end reservoirs, said end reservoirs being configured to store ink more readily consumed during a printing process. The cartridge also includes a lid assembly covering the main body to seal ink inside the ink reservoirs, and a printhead assembly operatively fed with ink from the ink reservoirs in the main body.
