Genuine OEM Ricoh SP C252 SF Toners
The SP C252 SF uses Ricoh SP C252HA toner, while the waste-toner bottle handles toner collected by the printer. These are different supplies: the cartridges provide color, and the bottle supports maintenance.
Toner Buzz carries genuine Ricoh 407653-407656 toner as a set and as individual colors for the SP C252 SF, plus the 406043 waste bottle. Use an individual color or the set for toner, and keep the bottle for its own maintenance role.
