Thank you for the question. Because of the iron oxide content in MICR toner, your printer must be modified to accept the magnetic quality of the toner. MICR toner is used in monochrome printers. Troygroup.com is authorized to modify and sell HP MICR-capable printers. (MICR toner cartridges are specialty toners used by the banking industry for check processing. MICR is an acronym that stands for magnetic ink character recognition. Each MICR cartridge is filled with a special toner powder designed specifically for check printing).
