Genuine black toner for T640, T642, T644

This Lexmark 64035HA cartridge is built for the T640, T642 and T644 laser printers. It delivers genuine black toner formulated for consistent output from the first page to the last. The supply is not compatible with other Lexmark printers. Offices needing reliable monochrome printing on these specific models will find it a direct fit.

Rated 21,000 pages under ISO/IEC 19752

The declared yield of 21,000 standard pages follows ISO/IEC 19752 test methodology. That figure represents sustained output across the full life of the cartridge rather than a short-run burst. Print density and page coverage in daily use will determine the actual number of pages produced before replacement is required.

Drop-in installation with no extra steps

The cartridge seats directly into the T640, T642 or T644 without tools or firmware updates. Common issues arise only when the model number is mismatched; the supply will not work in other Lexmark devices. Removing the sealing tape before insertion avoids streaks on early pages.

Questions about this item

Does the cartridge add any noise, heat or extra power draw when the T640 runs all day?

The cartridge is a passive toner supply; it has no moving parts or electronics, so it adds no audible noise, no measurable heat and no additional power draw during continuous printing.

Which printer models must I already own for the 64035HA to work?

The cartridge is designed only for Lexmark T640, T642 and T644 printers; it will not fit or function in any other Lexmark or non-Lexmark model.

Will the 64035HA work alongside an older T640 drum unit I plan to keep?

Yes, the toner cartridge is a separate consumable from the photoconductor drum, so it installs and operates normally with an existing T640 drum unit.
