Frequently Asked Questions

What is MICR?

MICR stands for Magnetic Ink Character Recognition. When printing with MICR one can create various documents that can be read and processed using a variety of devices. The most common use of MICR is the printing of account information on checks and other negotiable documents. MICR is also used on various other documents including coupons, rebate checks, parking and lottery tickets.

What do I need to print MICR?

In order to print your own MICR encoded documents, you will need a laser printer, MICR toner cartridge, check writing software with E13B font and a Clearwave Position and Dimension Gauge

Why do I need a MICR Cartridge?

Financial Institutions clear checks using a reader sorter that rely upon the signal levels emitted from the MICR encoded characters on your documents. A regular toner cartridge does not contain iron oxide which therefore does not ensure that your document will read correctly.

What could happen if I do not use MICR toner or purchase MICR toner from a reliable source?

If your financial institution is unable to process your checks automatically do to issues such as poor MICR signal level or misaligned character positioning, you may be subject to additional service fees. This charge can range from $0.50 to $6.00 per item. In the worst case your bank will not accept your checks until standards are met.
