Abstract
Provided is an ink cartridge unit for an inkjet printer. The cartridge unit includes a main body defining a number of ink reservoirs, each reservoir having a layered stack of absorbent material forming a micro-capillary array for suspending ink inside said reservoir. The unit 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. The unit further includes a capper assembly for operatively capping the printhead assembly to prevent damage to micro-electromechanical nozzle arrangements defined on a printing surface of the printhead assembly. The lid assembly includes a refill facility whereby the ink reservoirs are refillable with ink from a suitable ink refill unit.
