eSquareOne Compatible High Yield Toner Cartridge Black 4-Pack for Brother TN760 TN730

Four-pack toner for Brother laser printers

This set contains four new black toner cartridges from eSquareOne built to replace Brother TN760 and TN730 originals. They suit home offices and small businesses that run high-volume monochrome printing on compatible Brother HL, DCP and MFC models. Each cartridge is sealed in its own box with shock-resistant air bags and an installation guide. The pack covers extended print runs without frequent reordering.

Yield of 3000 pages per cartridge at 5 % coverage

The manufacturer rates each cartridge at 3000 pages using the ISO/IEC 19752 test pattern. That figure decides whether the pack matches your monthly output; heavier graphics or denser text will reduce the actual count. The toner is formulated for sharp text and photo reproduction that resists fading, smudging and bleeding. Buyers who need colour output or a different page-yield class should look elsewhere.

Straightforward drop-in replacement

Installation follows the standard Brother cartridge swap: open the front cover, remove the old unit, shake the new cartridge gently, insert until it clicks, then close the cover. The included guide illustrates the steps. The most common issue is forgetting to remove the protective seal or orange clip before insertion, which blocks toner flow. The cartridges carry a two-year guarantee and 24/7 support if defects appear.
