KODAK/ HERO 7.1 PRINTER / WILL NOT ALLOW ME TO USE THE LAST 35% OF THE INK IN CARTRIGE

WILL NOT ALLOW ME TO USE THE LAST 35% OF THE INK IN CARTRIGE. An error message comes up to say I am out of color ink (code 3508), When in fact the cartridge still has at lest 35% ink left. In an HONIST company, the error code would come up to let you know that you are getting low in ink, but KODAK stops the printing process until you change the cartridge. You can't even take it out and put it back. This is a robbery of 35% of your ink for every cartridge. If a gas station tried to take 35% of you gas there would be hell to pay!
