Genuine Lexmark black toner

This genuine Lexmark Unison toner cartridge delivers 28,000 pages of black output. It is engineered for consistent quality across the full yield and fits the Lexmark CX735 laser printer. The original formulation reduces waste and maintains sharp text from the first page to the last.

Offices that print high volumes on a CX735

Designed for workgroups that rely on the CX735 for daily monochrome documents. Buyers who need colour output or use a different printer model should look at the matching cyan, magenta and yellow cartridges or the correct series for their hardware.

Steady density over long print runs

Unison toner particles are sized for even flow during extended jobs, preventing streaks or fading as the cartridge empties. The return-program design supports Lexmark's recycling loop without affecting print performance.
