Yes i need help on my HP office jet J5780 cartridge 74 black CB335W and 75 color CB337W and i can't seem to match this with the universal inkjet refill and i have this product and i have used it on my old cannon bubble and it works great and i was wondering can i refill my new fax and copier with your product or do i have to still buy new cartridges, please help?

Thank You.
