Toner Black High Yield

Lexmark 64436XE is an extra high-yield print cartridge for black-and-white laser printing. It is designed for compatible Lexmark T644-series printers and supports extended print runs between cartridge changes.

The declared yield is up to 32,000 standard pages in one-sided printing, measured under ISO/IEC 19752. Actual page coverage varies with the material being printed, so this figure is a standardized yield reference.
