Toshiba T8570 Black Toner Cartridge – 88,700 Pages for e-STUDIO 557/657/757/857

Genuine Black Toner for High-Volume e-STUDIO Copiers

The Toshiba T8570 toner is a genuine black cartridge for the e-STUDIO 557, 657, 757 and 857 monochrome multifunction systems. Toshiba rates the cartridge at approximately 88,700 pages at 5% coverage. It carries the T8570 designation and cross-references to OEM codes 6AK00000289 and 6AK00000279. The cartridge ships sealed and installs in the black station without tools.

The cartridge uses laser electrophotographic toner formulated for the e-STUDIO 557/657/757/857 print engines. The black formulation holds text edges sharp and keeps solid fills even across long runs. Page yield depends on coverage, media size and the darkness setting selected on the machine. The 88,700-page figure follows the ISO/IEC 19752 test pattern at 5% coverage. High-coverage documents reduce the effective yield accordingly.

The housing includes the toner supply and the developer interface. A cartridge chip reports remaining volume to the printer control panel. The machine reads the chip at power-up and updates the consumable status display. Replacement follows the standard toner swap procedure and needs no calibration or firmware step. The sealed packaging protects the toner from moisture and light before installation.
