Lexmark compatible toner for cartridges used in Lexmark MS and MX series and Dell B3465 and B5465 printer families is specifically formulated and manufactured to match the OEM toner.
This is important because toner from the previous cartridge mixes with the toner from the next cartridge in the imaging unit. Toners that are not compatible will create excessive backgrounding during the mixing period that is objectionable to most end user customers.
