Genuine OEM Canon imageRUNNER Advance 4051i Toners

The Canon imageRUNNER Advance 4051i uses GPR-42 black toner, while its drum is sold separately under GPR-42/43. The different labels help distinguish the printing supply from the imaging component.

Toner Buzz carries both genuine Canon parts for this machine. Choose the GPR-42 toner cartridge when toner is needed, or the GPR-42/43 drum when the machine specifically needs its drum unit.
