Abstract

An ink printing system is described herein which includes a print cartridge, having an ink reservoir and an ink fill hole, and an ink refill system for engaging the print cartridge's ink fill hole and transferring ink to the ink reservoir. The ink fill hole has a stopper blocking the hole to prevent ink leakage through the hole. The ink refill system containing a supply of ink has a male valve, resembling a hollow needle, which is inserted through the ink fill hole and pushes the stopper into the ink bag. The male valve creates an airtight fluid communication path between the print cartridge and the ink supply in the ink refill system. Ink is then transferred from the ink refill system into the print cartridge. The ink refill system is then removed from the print cartridge. The male valve of the ink refill system has a releasable tip which is pulled into the ink fill hole to seal the ink fill hole. The tip is then released from the male valve such as by unscrewing the male valve from the tip.
