Abstract
An adaptive ink supply for an ink-jet printer is provided with the receptacle mountable to an ink-jet printer. The receptacle has four ink chambers for receiving ink cartridges having flexible ink reservoirs supported by a rigid frame. The receptacle chambers have spring-loaded pressure plates on either side of the chamber for pressurizing ink cartridges inserted therein. The ink cartridges are coupled to a fluid outlet which is normally closed to prevent the flow of ink. When the ink cartridge is inserted into a receptacle mounted to a printer, the fluid outlet establishes a fluid connection between the ink cartridge and the printer. The pressure plates exert a force against the ink cartridge causing ink to flow from the cartridge and to the printer.
