An inkjet print cartridge is described which has a first fill port, for initially filling the print cartridge with ink, and a refill port for recharging the print cartridge. The refill port includes a slideable valve which is engageable with a valve on an external ink reservoir to create an airtight fluid communication path between the print cartridge reservoir and the external ink reservoir.
