Description
Black Toner Cartridge for e-STUDIO Mono Copiers
The Toshiba T-4590D toner is a black laser cartridge for e-STUDIO 206L, 256, 306, 356, 456 and 506 copiers. It carries part number 6AG00004033 and yields approximately 36,000 pages at 5% coverage under ISO/IEC 19752. The sealed cartridge ships with 700 g of black toner and installs without tools.
The cartridge feeds a mono laser engine and holds density across long print runs. Toshiba specifies the yield against ISO/IEC 19752, which standardises page coverage and test conditions. Toner weight sits at 700 g, and the cartridge body matches the e-STUDIO toner bay dimensions. The unit also serves the 256SE, 306SE, 356SE and 456SE variants listed in the same family.
A new cartridge restores output when pages fade or show vertical bands. The technician opens the front cover, releases the old cartridge, and slides the replacement along the guide rails until it clicks. The copier then runs an automatic toner setup cycle. Sealed packaging protects the toner from humidity before installation.
