Compatible Black Cartridge for Toshiba E-Studio

This new aftermarket toner replaces the Toshiba T4590 cartridge and fits E-Studio 206L, 256, 306, 356, 456 and 506 models. It delivers a page yield of 36000 pages measured at five percent coverage. Offices with consistent mono printing needs will find it a direct drop-in solution.

Yield Headroom at Standard Coverage

At the rated five percent coverage the cartridge provides 36000 pages before replacement is required. Heavier graphics or dense text layouts will reduce the practical page count below that figure. Users printing mostly light correspondence can expect to reach the full yield. Those running high-coverage reports should plan for earlier changes.

Operating Range and Reliability

The toner is rated for use in environments between twenty and eighty percent relative humidity. Storage conditions share the same twenty to eighty percent range. Manufacturing follows ISO 9001 certified processes and the supplier backs the cartridge with a one-year replacement or refund guarantee. No special cooling or power considerations apply.

Questions about this item

Will the T4590 cartridge work in my Toshiba E-Studio 306 alongside the existing drum unit?

Yes, the T4590 is compatible with the Toshiba E-Studio 306 and other listed models, and installs independently of the drum unit.

How can I verify the T4590 is printing correctly after installation?

Print a test page; the cartridge should produce rich black text and clean gray shades at the rated 36000 pages based on 5% coverage.

Does the single T4590 pack include any installation tools or waste toner bottles?

The pack contains one black T4590 toner cartridge only; no tools or waste bottles are included.
