The Lexmark laser print cartridges are specifically designed to assure optimal print quality, with crisp, dark output from first print to last. A clean hands design means easy cartridge installation and removal. This print cartridge comes with oiled fuser wipers for customers that do extensive label printing. For use with Optra S 1250(n), 1620(n), 1650(n), 2420(n), 2450(n) and Optra S 1255(n), 1625(n), 1855(n) and 2455(n). Prebate supplies are now called Lexmark Return Program cartridges. Details of the license program remain the same. Only the name has changed. For a period of time, when you order a Return Program cartridge, you may receive a Prebate cartridge. We appreciate your patience during this transition. Lexmark Return Program Cartridges are sold at a discount versus the prices of regular cartridges in exchange for the customer's agreement to use the cartridge only once and return it only to Lexmark for remanufacturing or recycling. Regular cartridges without this license/agreement sold at regular prices are also available. Regular cartridges are also recyclable at no cost through Lexmark Cartridge Collection Program.
