Static Control's universal replacement toner is for use in a large group of Kyocera cartridges. The fill weight chart provides detailed information regarding the cartridges and printers. This toner 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.
