Abstract
Provided is an inkjet printer having an ink cartridge unit. The cartridge unit includes a main body defining a number of ink reservoirs. Each reservoir has a layered stack of absorbent material arranged to form a micro-capillary array for suspending ink inside said reservoir. A base of each ink storage reservoir is provided with a raised portion which surrounds an ink outlet. The raised portions are molded into the main body to separate each outlet from the base of the ink storage reservoir to facilitate a sufficient flow rate of ink from the reservoir. The cartridge unit also includes a lid assembly covering the main body to seal ink inside the ink reservoirs, as well as a printhead assembly operatively fed with ink via the ink outlets from the ink reservoirs in the main body for printing onto a printing medium.
