Q: Do I really need to use MICR toner to print checks?

A: Yes, if you want to minimize the possibility of additional bank charges. Although there is no law requiring magnetic ink, banks have the legal right to refuse to process checks, drafts, or deposit slips that are not printed with magnetic ink (toner). Banks use high-speed reader/sorter machines to process checks. These machines recognize the E-13B characters printed on the bottom (MICR) line of checks by their magnetic pattern, optical pattern, or a combination of both. Checks that cannot be read by these machines are rejected and must be manually re-encoded, usually with a narrow "repair tape" attached to the bottom of the check. Most banks charge a fee for this service when a large number of checks from an account holder are rejected. Another disadvantage of not using MICR toner is that your bank statements may be missing check numbers, making them harder to reconcile.


Q: Can I use MICR toner to print everything?

A: Yes, MICR toner is excellent for printing text and graphics as well as checks. By keeping the magnetic toner cartridge in the printer and not swapping it with a non-magnetic cartridge you decrease the possibility of accidentally printing checks with the wrong toner. It also reduces wear and tear on the printer.


Q: How can I find out which of your MICR toner cartridges is compatible with my laser printer?

A: Refer to our microMICR Toner Cartridge Selection Guide and find the Hewlett Packard or Lexmark model which you think is compatible. Click on the "Part #", which will bring you to a description of the cartridge and a comprehensive list of compatible printers from different manufacturers, if any. While we have attempted to be as thorough as possible, it is possible that some compatible models are not listed. Please contact our technical support if you need further assistance.


Q: Are magnetic ink jet cartridges available for my ink jet printer?

A: No, we are not aware of any magnetic ink jet cartridges currently on the market. Because of the wide variation of ink absorption with different papers, it is unlikely that an acceptable formula will be found that is capable of producing a consistent quality magnetic signal.
