ABSTRACT:
In the preferred embodiment, an inkjet printer includes a replaceable print cartridge which is inserted into a scanning carriage. An ink tube extends from the scanning carriage to a separate ink supply located within the printer. A fluid interconnect on the print cartridge connects to a fluid interconnect on the carriage when the print cartridge is inserted into the carriage to complete the fluid connection between the external ink supply and the print cartridge. In one embodiment, the fluid interconnection is made between the print cartridge and the ink tube simply by placing the print cartridge into a stall in the scanning carriage. A flexible ink conduit is connected to the fluid interconnect on the carriage to enable the fluid interconnect to have a degree of movement to allow precise alignment with the fluid interconnect on the print cartridge. A pressure regulator, which may be internal or external to the print cartridge, regulates the flow of ink from the external ink supply to the print cartridge. The external ink supply may be pressurized or non-pressurized.
