Genuine OEM Canon imageRUNNER Advance C7565i II Toners
If a GPR-56 color toner runs out in the C7565i II, black-and-white printing can continue while black toner remains. Print quality may drop, though, so this is a way to finish a black-and-white job, not a reason to ignore an empty color cartridge.
Toner Buzz carries genuine Canon GPR-56 black, cyan, magenta, and yellow toner individually and as a four-color set. Choose the individual GPR-56 color you need, or the set when you want black and all three colors together.
