Genuine OEM Canon imageRUNNER Advance C7570i II Toners
When GPR-56 color toner runs out, the C7570i II can keep printing in black and white if it still has black toner. That comes with a print-quality warning from Canon, so continuing a job does not mean the empty color cartridge can be left indefinitely.
At Toner Buzz, genuine Canon GPR-56 toner comes as individual black, cyan, magenta, and yellow cartridges or a set containing all four. An individual GPR-56 color handles one empty supply; the set brings the colors and black together in one order.
