What is the difference between MICR Ink and MICR Toner?

As stated, MICR stands for Magnetic Ink Character Recognition. It is also used in MICR toner for printing checks with a laser MICR printer. We recommend using MICR toner cartridges every time you decide to do check printing, so it will be secure and you do not incur bank fees.

Manual processes for check data are costly. So now banks require reader sorters instead. This is accomplished by using a magnetic charge toner that you cannot do with non MICR cartridges.

If you used non MICR cartridges during check printing, the banks will reject the checks since their check readers will not be able to read the MICR line on the bottom of the check. This MICR line includes the routing number, account number and check number.

This MICR line should always be printed using MICR toner. Here you will find the Most Popular MICR toner which includes what laser printers we recommend using for check printing.

You can find a printer at most office supply stores, as they carry HP LaserJet printers. But the printer will come with regular / non MICR toner, so you will need to purchase HP MICR toner made for your model of printer.

Most everyone uses HP LaserJet printers and not inkjet printers for check printing. An inkjet printer is not a good quality option. Inkjet printers used as an inkjet MICR printer can have clogged ink cartridge nozzles, and when a check is printed, it can have lines and quality issues.
