This alternative to the original Hewlett Packard 302XL black cartridge has been produced using an empty genuine cartridge.Once empty F6U68AE units have been procured, our manufactures have thoroughly tested and cleaned them before filling them with a high quality compatible black ink. The resulting remanufactured HP 302XL black cartridge retains as much of the superb print quality present in the original, but offers end users a welcome saving. Despite the lower price, this F6U68AE ink cartridge is filled with the same amount of black ink as a brand new Hewlett Packard cartridge and offers the same estimated page yield.
