Abstract
An inkjet print cartridge is described which incorporates an ink recharge port and recharge valve as part of the handle for the print cartridge. The handle is located to be easily accessible when the print cartridge is installed in a carriage within a printer. The handle provides protection for the recharge valve structure, and the valve structure does not interfere with the insertion of the print cartridge into existing carriages.
