This is a remanufactured Lexmark 12S0400 high yield black laser toner cartridge designed for use with Lexmark laser printers. It replaces the original Lexmark 12S0400 toner cartridge and is engineered for reliability and exceptional print quality. This cartridge features a smart chip that allows for a yield of up to 6,000 pages, making it a cost-effective alternative to the standard yield cartridge typically used in the Lexmark Optra E220 printer. The use of remanufactured cartridges does not void your printer warranty, and we back this product with a 100% Quality Satisfaction Guarantee.
