Genuine OEM Canon imageRUNNER Advance 400iF Toners

The 400iF uses GPR-48 black toner and a separate GPR-39 drum. Those different numbers are correct for this printer: GPR-48 is the toner cartridge, while GPR-39 is the drum unit. Choose by the supply the machine needs, rather than looking for matching family numbers.

Toner Buzz carries genuine Canon GPR-48 toner, 2788B003AA, and the GPR-39 drum, 2773B004AA. If you're ordering toner, choose GPR-48; the GPR-39 drum is for a separate drum change, not another toner option.
