Abstract

An ink refill unit is provided for refilling a printer ink cartridge unit. The ink refill unit includes a base assembly which houses internal ink refilling components and defines a plurality of outlets for docking with the cartridge unit. Each outlet corresponds to a respective type of ink with only one of the outlets working. The ink refilling components include a syringe assembly coupled in fluid communication with the working outlet. A lid assembly fits onto the base assembly to cover the ink refilling components.
