Genuine OEM Canon imageRUNNER Advance C7580i II Toners
Running out of GPR-56 cyan, magenta, or yellow toner does not necessarily prevent the C7580i II from finishing black-and-white pages. It can continue with black toner remaining, but print quality may be reduced. The empty color is still a supply to replenish.
For the C7580i II, Toner Buzz carries genuine Canon GPR-56 black and color toner separately, plus a set that includes black and all three colors. Choose a separate GPR-56 cartridge for one supply, or the set to order the full group together.
