Original toner Return Program by Lexmark for the printers:

• Lexmark MB3442i
• Lexmark B3340dw
• Lexmark B3442dw
• Lexmark MB3442adw

The toner that falls under Lexmark's Return Program is printing toner sold at a reduced price, in exchange for the customer agreeing that the cartridges will be used only once and returned only to Lexmark for remanufacturing or recycling. These single-use toners stop functioning when they reach the end of their designated life span, as determined by Lexmark (a variable amount of toner may remain in the cartridges when replacement is required). These toners can also automatically update the printer's memory to protect it from non-genuine and unauthorized products.
