Genuine OEM Canon imageRUNNER Advance 4045 Toners

The Canon imageRUNNER Advance 4045 has a GPR-42 black toner cartridge and a separate GPR-42/43 drum. Toner is used up through printing, while the drum is the machine's imaging unit.

Toner Buzz carries both genuine Canon choices for this model. Pick the GPR-42 cartridge when you need toner, and pick the GPR-42/43 drum only when the drum itself is the required part.
