MICR is an acronym for Magnetic Ink Character Recognition. It describes the special typeface and ink used to encode the numbers and symbols printed on the bottom line of checks and other documents for high-speed magnetic or optical processing by banks. Every MicroMICR toner is made from a brand new Original Manufacturer cartridge and is identified by a bright red MICR sticker. They contain all original components, factory seal intact, and are filled by MicroMICR with MICR toner tested to meet ANSI/ABA standards and to yield the highest consistent quality.
