Toshiba T478SUR Black Toner Cartridge 20000 Pages

Genuine black toner cartridge

The Toshiba T478SUR is an original black toner cartridge supplied in a single pack. It is designed for compatible Toshiba laser printers that require this specific model. Offices and workgroups use it to produce crisp monochrome documents on a daily basis. The genuine formulation helps maintain consistent print quality throughout the cartridge life.

Suitable for high-volume mono printing

This cartridge suits environments that print large quantities of black-only pages and prefer manufacturer-supplied consumables. Buyers who need colour output or a multi-pack should look at other options. It is not intended for inkjet printers or for models that use a different toner series. Compatibility with the target printer must be confirmed before purchase.

Rated yield of 20000 pages at 5% coverage

The key specification is the estimated yield of 20000 pages measured at 5% page coverage. Actual page count will vary with document density, print settings and environmental conditions. This figure is the primary basis for calculating cost per page and planning replacement intervals. No other capacity or yield ratings apply to this model.
