Genuine OEM Sharp MX-B400P Toners

The MX-B400P uses MXB40NT1 black toner, but its black developer and drum have MXC40 names: MXC40NVB and MXC40NRB. Those C40 prefixes don't make them color toner cartridges. Sharp lists them as separate black maintenance supplies for this monochrome printer.

Toner Buzz carries genuine Sharp MXB40NT1 black toner, MXC40NVB black developer and the MXC40NRB black drum. Choose MXB40NT1 for a toner order. The developer and drum are distinct maintenance purchases and aren't included with the toner cartridge.
