Magnetic Ink Character Recognition (MICR), a technology invented in the 1950s has allowed financial institutions to streamline their check processing. The characters are printed with special MICR Fonts and are known as MICR Characters, which must be printed with MICR Toner or MICR Ink. It is the combination of Toner and Fonts that create the machine readable MICR line. MICR Toner or MICR Ink are the elements which add the magnetic readability to each character, allowing for high-speed check clearing. Producers of MICR-encoded documents must meet ANSI document preparation standards.

MICR Fonts are the characters that appear at the bottom of checks or financial documents. There are two different fonts which are used depending on established banking standards in the country. These fonts are E-13B and CMC-7.
The E-13B Font looks like this:
Currently, this font or MICR Character set is used in the United States of America, Canada, Australia, United Kingdom, Japan, India, Mexico, Colombia, and Turkey.
Where did the name E13-B come from?
E: signifies that it was the 5th version of the font considered.
B: signifies that it was the second revision of that font.
13: references the fact that the MICR font is constructed on a .013” module for stroke and character width.
The CMC-7 Font looks like this:
Currently this font or MICR Character set is used in France, Spain, Israel, South America (except Colombia) and other Mediterranean Countries.
This line consists of ten specially designed numbers (0 through 9) and four special symbols (Transit, Amount, On-Us, and Dash). The combination of characters and numbers provide the check, routing, and account numbers on a check. They can also provide the check amount.
Read from right to left Positions 1 through 12 host the Amount Field; Positions 13 through 32 host the On-Us Field; Positions 33 through 43 host the Transit Field; Positions 45 up to as many digits that will fit the size of the check host the Aux On-Us Field.
Though important, MICR is only one element of the check printing process. To receive the most accurate MICR line it is encouraged that printer specific MICR fonts are used. When using a printer agnostic MICR font downloaded from the internet, the MICR line could cause issues with banks and MICR readers. Learn more about MICR lines from the following websites:

MICR Toner is a specialty toner which provides the magnetic charge, allowing the MICR line to be read. MICR Toner is placed into a laserjet printer when you need to print checks. In many cases the MICR Toner can be used in your current laserjet printer, but in some cases the laserjet printer settings must be reconfigured in order to print MICR documents that meet banking specifications.
As inkjet printers become more popular so does the need for MICR ink. MICR ink is applied as an ink base solution. MICR ink carries similar features to MICR toner. MICR ink is a perfect MICR solution for mobile check printing. The typical inkjet printer is smaller in size when compared to a laserjet printer. This allows for on the go check printing options for MICR ink.
OEM vs. Remanufactured MICR Toner:
MICR Toner can be found in an original or remanufactured cartridge. Cartridges are designed for a single use. Reusing can comprise the quality and output of a cartridge. Remanufactured toner cartridges can be known to cause toner streaks down the side of checks after a few prints. Take a look at some statistics provided by HP. Using OEM cartridges for MICR check printing not only provides the highest readability, but they also do not void your HP warranty. Remanufactured toner cartridges void HP's printer warranty. While you may pay a little more for OEM MICR toner, the quality and the reliability is priceless.
MICR Toner Maintenance:
MICR Toner Storage
Ferromagnetic toners used in the MICR Printers are sensitive to heat and moisture. After your toner cartridge arrives, it could become damaged if it is not stored in the proper environment. If the temperature and moisture ranges in your transportation and/or storage area are not within the ranges listed below, please arrange new transportation or storage locations.
MICR Toner Storage Temperature
Toner should not be stored in temperatures below zero degrees C (-32 degrees F) or above 35 degrees C (95 degrees F). Toner should not remain at these extremes for 12 hours or longer. Operating temperature should be between 10 degrees C (50 degrees F) and 32.5 degrees C (91 degrees F). Toner should be normalized at printing temperature for a minimum of 24 hours prior to use. Do not store toner in direct sunlight, near a heat source, or in dusty places.
Do not store the toner in environments with higher than 65% or lower than 10% relative humidity; or with extreme changes in humidity. Operating relative humidity should be 20% to 80%.
MICR Printers can be viewed two ways, first as a printing company who is producing personal check books, and second as a special desktop printer from which MICR documents can be produced. This definition will reference the second use of the term.
A MICR Printer is a printing device which provides the ability to print a magnetically charged set of characters on the bottom of a check, also known as MICR fonts. MICR Printers can be as simple as an off-the-shelf laser printer with an embedded MICR font, or a customized printer with numerous security features. Updates in recent technology have posed the question Do I still need a MICR printer? The answer is YES! MICR printers not only give you the ability to print checks, but they also add layers of security to your check stock helping to eliminate the chances for check fraud. Some MICR Printers can use both standard toner (non-magnetic) and MICR Toner, while others use only MICR Toner. By using a MICR printer you are eliminating the need for preprinted check stock. Not only can this save up to .10 per check, but it also eliminates the need for chain of custody around check stock. Additional features may include locking trays, toner sensing, MICR character positioning, and disable jam recovery. With 75% of companies stating they experienced actual or attempted check fraud in 2016, MICR printer security is more important than ever. Visit our HP based MICR printers page for more information.

Check Stock for MICR Printing:
In the United States, ANSI paper specifications mandate a minimum basis weight of 20 lbs. (short grain documents) and a basis weight of 24 lbs. (+/- 5%) for long-grain documents. Grain long documents provide higher strength and stiffness properties for the check during printing and reading. Paper smoothness (Sheffield) should be between 50 and 200 for all laser printed checks Actual check width must be at least 6.00” and not more than 8.75”. Check height must be at least 2.75” and not more than 3.66”.
MICR is a technology which uses magnetically charged
ink or toner to print the numbers and special characters
on the bottom of checks or other financial documents.
