Genuine Toshiba T-8570U black toner

This genuine Toshiba T-8570U cartridge delivers black toner for the E STUDIO 557, 657, 757 and 857 series. It is built for offices that rely on consistent monochrome output across these specific models. The cartridge is supplied new and carries the original manufacturer formulation. Buyers needing colour toner or cartridges for other printer lines should look elsewhere.

73900-page yield at 5% coverage

The rated yield of 73900 pages at 5% coverage lets high-volume departments plan replacements less frequently. This figure follows the standard measurement method so you can compare it directly with other cartridges tested the same way. No additional software, chips or hardware are bundled with the cartridge itself. Organisations that track cost per page gain a reliable baseline for budgeting.

Straightforward drop-in installation

Installation follows the standard front-access procedure for the E STUDIO 557, 657, 757 and 857 devices: open the toner compartment, remove the old unit, shake the new cartridge gently, insert until it clicks and close the cover. The most common issue is forgetting to remove the sealing tape before insertion, which causes blank pages. Ensure the printer recognises the new cartridge before starting a large job.
