Genuine OEM Canon imageRUNNER Advance 4525i III Toners

The 4525i III uses GPR-57 black toner, and its low-toner warning gives you time to prepare a new cartridge. Keep the current cartridge in place until the machine asks you to change it; the early warning isn't an instruction to take it out.

Toner Buzz carries the genuine Canon GPR-57 black cartridge for the imageRUNNER ADVANCE 4525i III. The individual 0473C003AA cartridge is the toner to have ready for that change.
