TCT TN229XLBK Black Toner Cartridge 2 Pack 3000 Pages

TCT TN229XLBK Black Toner Two-Pack

This twin-pack of high-yield black toner cartridges from TCT replaces Brother TN229XLBK units and is designed for owners of MFC-L3780CDW, HL-L3280CDW, HL-L3220CW and MFC-L3720CDW printers who want crisp text and consistent dark tones across high-volume print jobs. Each cartridge is rated for approximately 3000 pages at five percent coverage, so the pair supports extended output without frequent swaps. Buyers who need colour toner or single-cartridge purchases will not be served by this listing.

Thermal and power behaviour in normal use

As a toner cartridge this product generates no heat, draws no power and produces no audible noise of its own; all thermal, acoustic and electrical characteristics belong to the printer hardware it is installed in. The cartridge simply supplies fused toner to the imaging process during standard office printing. No independent thermal or power metrics exist for the cartridge itself.

Sustained-load performance

Under continuous high-volume printing the cartridge maintains its rated yield of 3000 pages at five percent coverage, delivering consistent density and sharpness from the first page to the last. Page-to-page uniformity is preserved across long runs because the toner formulation and drum integration are matched to the compatible Brother models listed. The two-pack format ensures a spare is on hand when the first cartridge reaches end of life.
