Lexmark 56F0Z00 imaging unit is a monochrome laser printing component for compatible Lexmark printers. It is part of the Lexmark Return Program and is designed to work with Unison toner.
Its rated yield is up to 60,000 pages. Actual yield can vary with use, so this figure is an estimate rather than a guaranteed page count. The unit supports black-and-white laser printing in compatible devices, including the Lexmark MS321dn and MX321adn.
As a Return Program supply, it stops working when it reaches its rated life. After use, it is returned to Lexmark for remanufacturing or recycling.
