Three parts of one check print path, from one vendor

Finance and operations teams usually assemble check printing from three suppliers: a printer vendor, a software vendor, and whoever sells the toner. We supply all three, which is what makes the MICR Performance Guarantee possible at all.

MICR printers

Ricoh print engines re-engineered into MICR-capable hardware, from a Ricoh P 311 for a single payroll department to a Ricoh Pro 8420 running 136 pages per minute. Every product page names its engine.

ProMark MICR toner and supplies

The first polyester-based MICR toner in the industry. A polyester base holds together and tolerates heat better than the polystyrene base most MICR toner still uses, which is where the reject-rate difference comes from.

Why the reject rate matters

A rejected check is a bank fee, not a reprint

When a reader/sorter cannot read the magnetic line on a check, the item is rejected and handled by exception. Banks charge for items over their acceptable reject rate. The toner is what decides how often that happens.

  • Tested on the machine that judges it

    The 0.1% figure comes from independent testing on an IBM 3890 high-speed reader/sorter, which is the class of machine that decides whether a check clears or gets kicked out.

  • A polyester base, not polystyrene

    ProMark MICR toner is the first polyester-based MICR toner in the industry. It holds together under heat and handling, so the magnetic signal on the line survives the trip through a sorter.

  • One vendor for the whole print path

    The printer, the software, and the toner all come from us. When MICR quality is in question, there is no argument between three suppliers about whose part caused it.

MICR toner reject rate

Lower is better. Rejected items are handled by exception and billed by the bank.

ProMark MICR toner 0.1% or lower
Typical MICR toner 2% to 4%

Why a reject rate is a cost rather than a quality score

  1. A weak MICR signal

    A worn fuser, the wrong toner, or paper outside the specification.

  2. The bank rejects the item

    The reader/sorter cannot read it magnetically.

  3. Exception handling

    The item is processed by hand at the bank.

  4. A bank fee

    Charged on rejects above the rate your bank accepts.

The toner is the first link in that chain

ProMark MICR toner tests at a 0.1 percent reject rate or lower. The industry-typical range is 2 to 4 percent.

MICR printers

From a desktop unit to 136 pages per minute

We re-engineer proven Ricoh print engines into MICR-capable hardware rather than building proprietary printers from scratch. The desktop P 311M is built on a Ricoh P 311 and the production Pro 8410M / 8420M on a Ricoh Pro 8420. The engine is a machine your service organization already supports. The MICR path is what we build.

Magnetic ink character recognition

What MICR is, in plain terms

Most people meet MICR without knowing its name. It is the row of angular characters along the bottom of every check.

What is MICR?

MICR stands for magnetic ink character recognition. It is a technology that prints characters in magnetic ink or toner so a machine can read them by their magnetic signal rather than by their shape. Banks use it to sort and clear checks at high speed.

What is the MICR line on a check?

The MICR line is the row of characters printed along the bottom edge of a check. It carries the bank routing number, the account number, and the check number, printed in the E-13B character set. A reader/sorter at the bank reads that line magnetically to route the item.

What makes a MICR check different from a regular printed check?

A MICR check has its MICR line printed with magnetic toner on a printer calibrated for MICR output. A check printed on an ordinary office printer with ordinary toner looks similar to a person but carries no usable magnetic signal, so a reader/sorter rejects it and the item is handled by hand.

Why do checks get rejected by a bank reader/sorter?

A reader/sorter rejects an item when the magnetic signal on the MICR line is too weak, too strong, or misshapen. Common causes are non-MICR toner, a printer that is out of calibration, worn fuser components, or paper that is not designed for the process. Banks charge for rejected items over their acceptable rate.

What makes a printer a MICR printer

  1. Magnetic tonerIron oxide gives the characters a magnetic signature.
  2. CalibrationProduction verified on a MICR verifier before it ships.
  3. Certified fontsE-13B or CMC-7, tuned to the engine and the toner.

All three present, and the item clears. The reader/sorter reads the line. With only the toner, the check looks right to a person and is rejected by the machine.

The most expensive mistake in this category is assuming MICR is a supply rather than a system.

The MICR Performance Guarantee

If your bank reports a MICR quality problem, we investigate it. Where the problem is verified as caused by our materials or modifications and cannot be resolved, we reimburse the fees your bank charges for rejected checks over their acceptable rate.

Applies to Rosetta Technologies branded Ricoh printers purchased in the United States or Canada from us or an authorized reseller, operated with approved supplies and our MICR fonts, and maintained under an approved service plan. Full conditions on the guarantee page.
