Printer having multi-chamber print cartridges and off-carriage regulator - Patent US6183076(B1)

Filed: Oct 24, 1996

Abstract

An inkjet printer includes at least one print cartridge mounted in a scanning carriage having an ink interconnect coupled, via a flexible tube, to an ink output of a stationary pressure regulator. An ink input of the pressure regulator is connected, via a tube, to a stationary ink supply having replaceable ink cartridges. The print cartridge contains one or more printheads and one or more ink interconnects, one interconnect for each color ink which is printable by the print cartridge. To avoid ink pressure spikes due to the momentum of the ink in the flexible ink tube as the carriage scans across the medium, a flexible diaphragm is incorporated in the ink chamber of the print cartridge. The print cartridge is inserted in the scanning carriage so as to create a fluid coupling between the printhead and the flexible tube leading to the scanning carriage.
