For use exclusively in Canon ink tank printers like the Pixma G1400, the yellow ink within the 0666C001 bottle cartridge has been specially formulated to work in these very unique printers. Relying upon large reservoirs of black, cyan magenta and yellow ink, the GI-490Y ink is just one of the four bottles for use with this series of Canon inkjet printers.With an estimated 7,000 prints from each competitively priced Canon 0666C001 bottle, you get a staggeringly low cost per page, whether you print photos or everyday paperwork. Canon have invalidated the need for traditional ink cartridges with the GI-490Y and its accompanying colours and we fully endorse buying genuine Canon ink in bulk via this method.
