Lexmark 55B2H00 is a black-and-white laser toner cartridge for compatible Lexmark printers. This high-yield Return Programme cartridge is intended for regular document printing and has a declared yield of up to 15,000 standard pages in one-sided mode, measured under ISO/IEC 19752.
It uses Lexmark Unison toner and is listed for the MS331dn, MS431dn, MX331adn, MX431adn and MX432adwe. The named compatibility makes it suitable for replacing the cartridge in those printer models.
This is a single-use Return Programme cartridge: it stops working at the end of its rated life, and the empty cartridge must be returned to Lexmark for remanufacturing or recycling.
