For use exclusively in Canon ink tank printers like the Pixma G4400, the black ink within the GI-490PGBK 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 0663C001 ink is just one of four bottles for use with this series of Canon inkjet printers.With an estimated 6,000 prints from each competitively priced Canon GI-490PGBK 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 0663C001 and its accompanying colours and we fully endorse buying genuine Canon ink in bulk via this method.
