  • Page 11: Overview

    Overview MICR (Magnetic Ink Character Recognition) is a process by which documents are printed using magnetic ink and special fonts to create machine readable information for quick document processing. Although traditionally MICR has been used to print accounting and routing information on bank checks and other negotiable documents, the magnetic encoding lends itself to any form of document processing.
  • Page 12: A Brief History

    Overview A brief history Originally, checks were processed manually. However, by the mid-1940s the banking system became inundated with paper as society grew more mobile and affluent. Finding a means of handling the growing number of paper documents became vital to bankers.
  • Page 13 Overview In 1963, the American National Standards Institute (ANSI) accepted the ABA specifications, with minor revisions, as the American standard for MICR printing. The ANSI publication covering these standards is Print Specifications for Magnetic Ink Character Recognition, first issued in 1969. Although compliance with the standards is voluntary in the U.

  • Page 19: Production Cycle Of A Check

    Overview 7. Checks drawn on other banks are sent to the payor bank through a clearing (7) arrangement. The check may be cleared through the Federal Reserve, a correspondent bank, a clearing house, or directly by the issuing bank. The payor bank also balances the check against the deposit ticket (proof of deposit) (7a) to verify the check amount, and performs its capture pass (7b) on the reader sorter in order to identify the issuer account (7c).

Samples pass internal quality checks. 4. Samples are forwarded to the bank for approval. 5. Any problems are referred to application developers, who ensure that the problems cannot occur in production.
  • Page 21: Changes In Check Creation Role

    The introduction of MICR impact printers allowed the check issuer to sometimes take over printing the MICR line. With further technological advances, such as the Xerox MICR printing systems, the check issuer has assumed still more responsibilities that previously belonged to the manufacturer.

    They also provide great flexibility in font selectivity, graphics capability, and dynamic page formatting. An advantage to Xerox printing systems is their ability to print a document in a single pass, as shown in the following figure. The form design, variable data, logos, and signatures can all be printed together.
  • Page 26: Micr Printing Technologies

    Environment MICR printing technologies The following basic printing techniques are capable of generating magnetic characters: • Letterpress Letterpress is based upon a raised typeface that sits above the plane of the image carrier. The typeface is inked with special magnetic ink and applied to the paper under pressure.

    (U.S. market) or 90 gsm xerographic paper. Lighter papers often cause misfeeds, and heavier papers are more subject to jams (although most Xerox printing systems can handle a wide range of paper weights). In multi-pass reader sorter processing, lighter weight papers subject to frequent misfeeds and mechanical stresses, and are not as reliable as 24 pound paper.
  • Page 32: Grain Direction

    Paper facts Grain direction Paper properties are related to the grain direction. The grain of a paper is the direction in which most of its fibers lie, as shown in the following figure. Long grain papers are cut so that the fibers are aligned with the long dimension of the cut sheet.
  • Page 33: Moisture Content

    Papers with a nominal moisture content of 4.7 per cent perform best in Xerox MICR laser printers. Offset and bond papers may have a higher moisture content than xerographic papers. Xerox brand papers have a maximum moisture content of 5.3 percent, with an average of 4.7 per cent.
  • Page 34: Curl

    Paper facts Requirements for background reflectance are discussed in chapter 4, “Document design.” Curl All papers curl to some degree. Excessive curl is one of the most common causes of paper jams. Selecting a low-curl paper with the proper moisture content makes a significant difference in the productivity of your system.
  • Page 35: Metallic Content

    (skips, blurs, and deletions) due to their reduced ability to bend. 24 pound/90 gsm paper usually provides stiffness levels in the range needed by the Xerox MICR laser printer and the proofing, reader sorter, and remittance-processing systems used in banking environments.

  • Page 41: Preprinted Forms Considerations

    Inks Choosing the correct ink is the first step in designing forms that function well in Xerox printers. Inks for these forms must cure well, must not be tacky, and must not offset. In choosing an ink, you must consider the amount of heat and pressure to which the forms will be exposed while passing through the printer.
  • Page 42: Security Features

    Laser inks may be oxidative, UV, or heat set types. Another option is to use Xerox forms, whose performance is guaranteed. The same guarantee should be expected of the forms vendor chosen by the customer.
  • Page 43: Alteration Prevention

    Paper facts • Watermark: A variation that is made in the opacity of the paper during manufacturing. An artificial watermark is typically a white ink image that is printed on the back of the check. • Drop-out ink: Very low density ink that is used to print a message, usually on the back of the check •...
  • Page 44: Features To Avoid

    Paper facts • To achieve reconciliation without substantial waste, always use the stock sheets in the same order—lowest to highest— so that the sequence remains intact. • Avoid gaps in the sequence. • Storing unused stock without wrapping may cause runability problems the next time it is used.
  • Page 45 Paper facts • Many security features must be located in areas of the document where the printer places critical information, such as the payee name and the check amount fields. However, if the feature interferes with the bonding of dry ink to paper, poor image permanence results.

  • Page 47: Document Design

    Document design Although other applications are possible, a MICR document is typically a negotiable document, very often a check. However, all types of MICR documents must be produced in accordance with the standards and methods that have been established for checks, in order for the automated payment systems to process them.
  • Page 48: Background Printing

    Document design Background printing While MICR documents may be printed on white or pastel colored paper, negotiable documents nearly always have some sort of background—a scenic image, a logo, or a pattern. Fixed form and variable information should print darker than this background.
  • Page 49: Amount Lines

    Convenience Amount field should be retained to aid in locating this data. NOTE: The Xerox MICR fonts contain a dollar symbol, which is acceptable for all applications. The area for the Amount in Words is normally located left of the Convenience Amount, but may be above it or below it.
  • Page 50: Signature Lines

    The minimum clear band dimension for Xerox MICR printers is ¾ inch/19 mm, because the line printed by a Xerox MICR printer is magnetic and therefore must be kept out of the MICR clear band over the entire allowable registration range.

  • Page 53: Format Specifications Using E13B

    Document design Format specifications using E13B The recommended clear band dimension for Xerox MICR printers using the E13B font is 3/4 inch/19 mm, to provide for tolerances of the printing and finishing systems, and to allow an extra margin of safety between the clear band and the magnetic ink on the rest of the check.
  • Page 54: Transit Symbol

    Document design Transit symbol The two Transit symbols tell the reader sorter that the numerals between these symbols are the routing number that identifies the institution on which the check is drawn and where the document should be sent for processing. Checks are not processed in branch offices, but in central processing locations, which ensures that documents take the shortest route and the shortest processing time.
  • Page 55: E13B Character Design

    Document design E13B character design All of the E13B characters are designed on a 7 by 9 matrix of 0.013 inch/0.33 mm squares (see figure 4-5.). The minimum character width is four squares (or 0.052 inch/1.3 mm) for the numbers 1 and 2. The maximum width is 0.091 inch/2.3 mm for the number 8, 0, and four special symbols.

  • Page 75: Document Processing

    Document processing The life cycle for a MICR document involves three types of processing equipment: • Proof machine • Reader sorter • Repair station Proof machine The proof machine transfers the amount from the Convenience Amount field to the MICR encoded Amount field. It prints the Amount field onto the check using either a thermal transfer or an impact ribbon printer.
  • Page 76: Proofing Checks

    Document processing Proofing checks All checks start automated processing in the Proof of Deposit department. Check processing relies on a series of debits and credits throughout the process to identify errors as close to the source as possible. The first step is to prove that the deposit is valid. A deposit slip is balanced against the value of the items deposited with it.
  • Page 77: Reader Sorter Function

    Paper roughness must be controlled. Also, for MICR laser printers, which apply a release agent or oil to the fuser, the specified fuser agent must be used and the metering system maintained according to Xerox schedules. Reader sorter function Reader sorters are machines that read magnetic ink characters that are printed using the E13B or the CMC7 fonts.
  • Page 78: Waveform Generation

    Document processing Waveform generation All types of reader sorters react to any magnetic material in the clear band, intentionally placed on a document or not. Reader sorters read from right to left and the magnetized ink generates a waveform. The following figure illustrates the process.
  • Page 79: Types Of Reader Sorters

    Document processing Types of reader sorters The following recognition technologies have been incorporated into MICR reader sorter devices. Waveform reader sorters Waveform reader sorters measure the magnetic signal waveform or pattern of the MICR character as the documents pass the read head.
  • Page 80: Optical Reader Sorters

    Document processing Optical reader sorters Optical readers typically use a light source and some type of photosensitive matrix array to convert an image of the character into a set of electrical signals. Optical readers that can interpret the characters can be used to input data into an automated reading system.
  • Page 81: Hybrid Magnetic And Optical Reader Sorters

    Document processing Hybrid magnetic and optical reader sorters Hybrid reader sorters use two read technologies: • Magnetic waveform recognition • Optical character recognition Compared to other types, hybrid reader sorters have very high accuracy rates, because they interpret and compare the results produced by the magnetic waveform recognition and the optical character recognition.
  • Page 82: Paper Handling By Reader Sorters

    Document processing Medium speed: Process 1,000 to 1,500 documents per minute. These machines usually use waveform recognition, frequently with dual or hybrid read. High speed: Process 2,000 or more documents per minute. These machines are typically found in larger banks, clearinghouses, processing centers, etc.
  • Page 83: Aligner

    Document processing Aligner Within the aligner, a series of wheels drive the bottom edge of the document toward the back side of the reader sorter so that the MICR line is in a predictable location. The wheels have a series of plastic fingers that make contact with the back side of the document and force it against the aligner drum.
  • Page 84: Sorter Pockets

    Document processing Sorter pockets The document finally arrives at a diverter plate, which sends it into the pocket that the reader sorter program selects based on the MICR line data. The pocket has a pair of metal springs that press the document onto the stack that is in the pocket. If the pocket is empty, the document may impact against the rails at the bottom of the pockets with greater than normal velocity.
  • Page 85 Document processing If the document is badly damaged, or if the processing center does not have an automated repair station, a document carrier envelope may be used. This is a check-sized, translucent envelope designed to fully enclose a check while adding a new MICR clear band and encoding area at the bottom.

    Quality control MICR printing requires constant quality control. Special equipment is required to produce quality documents that meet the X9.27, X9.13, X9.7, and ISO 1004 specifications. You should develop a formal quality control program to ensure that all check printing specifications are met. Key factors for producing good MICR documents include: •...
  • Page 88: Optical Tools Used To Check Micr

    MICR tools are required to determine if a document is within specifications. MICR Gauge The MICR Gauge lets you compare the location of Xerox MICR printed information to industry standards. The Gauge is printed on a thin sheet of flexible plastic, which is attached to the bottom of a piece of hard plastic.
  • Page 89: Small Optical Comparator

    These are characteristics of the printing technology and font design, and cannot be adjusted in Xerox MICR printers. For this reason, the signal strength of the On-Us symbol is used as the Xerox reference for the entire MICR line. Generic MICR Fundamentals Guide...
  • Page 90: E13B Calibration Document

    Quality control MICR signal strength is the only magnetic specification in ANSI standards. Magnetic testers are needed to identify magnetic versus non-magnetic extraneous ink, and they can be useful in interpreting waveform uniformity issues. All other standards use optical dimensions and require optical or visual inspection. MICR quality decisions cannot be based solely on magnetic test equipment without regard to ANSI standard conformance requirements.

    Quality control The vertical position for the entire line is evaluated with the MICR Gauge. To check the vertical position, line up the right edge of the check with the right edge of the gauge, and place the bottom edge of the check as far down as possible between the flexible and the hard plastic on the gauge.
  • Page 96 Quality control Character skew does not occur with Xerox printing systems. However, line skew may occur if the paper skews when passing through the printer or is poorly cut along the critical edge (see the following figure). Out of specification Figure 6-7.
  • Page 97: Character-To-Character Spacing

    Quality control 2. Hold the document firmly so that it does not slip. The bottom of the document should now bisect the vertical skew scales below boxes 10 and 46. The scales are graduated in 0.5 degree divisions from 0 (not marked) to 2.5 degrees (also not marked).
  • Page 98 Quality control Figure 6-9. Character spacing If it is possible to move the check so that all characters are within a character box, place the right edges of as many characters as possible at the right edges of their character boxes. Look at the entire line and notice any characters whose right edges are not touching the right edges of their boxes.
  • Page 99: Voids

    This problem occurs more often with cold fusion xerography and ionography technologies than with hot fusion based xerography (like Xerox MICR systems). Voids must be contained within a 0.008 inch/0.2 mm square. An exception is made for internal voids that extend over two or more zones of characters, a zone consisting of 0.013 by 0.013 inch/...

    Quality control Single voids Acceptable Not acceptable Trail edge deletion (Note: This depends on the check printing orientation.) Figure 6-10. Examples of voids Extraneous ink spots Extraneous ink spots are unwanted bits of ink that result from unavoidable splatter and smear of the magnetic printing inks. These spots, which may be invisible to the unaided eye, can affect the wave patterns of MICR characters, depending upon their size, quantity, and position.

    Operational maintenance The performance of any mechanical device, whether a high- speed reader sorter or a Xerox printing system, depends on how well it is set up and maintained. Refer to the reference manual for your product to find out how to avoid possible problems.
  • Page 109: Quality Measurements: Magnetic Versus Optical

    Quality control Quality measurements: magnetic versus optical If a MICR quality issue arises, it should be visible on the printed document. Even signal strength problems can be seen if prints are compared. Low signal characters are thin and poorly formed; high signal characters are fat and usually surrounded by xerographic background.
  • Page 110 – MICR test equipment precision is limited by digitizer resolution. The minimum encoding interval limits the precision of a single measurement. In Xerox’s RDM MICR Qualifier GTs, this interval is 0.00104 inch/0.026 mm— one-third of the tolerance. – Digital MICR font designs are optimized for recognition performance in the full range of equipment used in check processing.

    Quality control • When the results are displayed, the use of a template with highlighted “bad areas” does not indicate if there is a specification failure due to edge void and edge irregularity allowances. The dimensions of the template may be limited by screen resolution.
  • Page 113: Problem Solving

    Problem solving MICR problem investigations take different forms, depending on the nature of the problem, the availability of actual problem documents, and the willingness of the parties involved. Timely problem identification and resolution is especially important for products covered by the MICR Quality Guarantee. When problem solving is required New accounts If the customer is opening a new account or validating a new...
  • Page 114: Possible Misinterpretations

    Problem solving • The customer may issue checks from a single account that uses multiple printers. These printers may not all be Xerox printers and they may be located in different cities. • The account holder may possess a blank check book order for years before using all the checks.
  • Page 115 Problem solving A structured approach is required to discern which of the many sources is actually responsible for a high reject rate. The following flow chart illustrates the steps. Problem reported From From internal QC reviewing returned operators Reported from bank checks Gather information Obtain rejected checks...
  • Page 116: Determining The Problem Source

    Problem solving Determining the problem source You must identify the source of the problem before you can implement corrective actions. For document quality problems, you can best identify the cause by examining the rejected document and determining the most likely reason for rejection. However, rejected documents may not be available, or they may not show any printer or application-related issues.
  • Page 117: Application Software

    Problem solving Application software Any application change should be reason for a thorough inspection. Although new applications must be thoroughly tested before MICR documents are issued, subtle application changes can have an impact on MICR document performance. Some problems, such as a new authorized signature that extends into the MICR clear band, are easy to detect.
  • Page 118: Interpreting Test Results

    Problem solving • Process documents through the reader sorters a minimum of 20 passes. • Use more than one reader sorter of the same model, if available. • Retain a control batch of the test deck from processing in case there is a need for later runs. •...
  • Page 119: Questions To Consider

    Problem solving Questions to consider When analyzing the results from a batch of documents that were tested in a reader sorter, you must ensure that the returned documents correspond to the reported rejects. You should ask the following questions: • What is the reject rate? This varies depending on the reader sorter that was used.
  • Page 120 Problem solving A statistically significant test to detect a 0.5 per cent rejection rate can be achieved with 2,000 to 3,000 documents. (The test case should not be less than 200 documents.) If the test set is too small, it may be biased by the fact that reader sorter performance is poorer when the machine is starting up than when it has been operating steadily for some time.
  • Page 121: Expected Reject Rates

    0.5 per cent for unprocessed documents in good condition. Xerox MICR documents are expected to be rejected less than 0.5 per cent on the first pass in high speed reader sorter tests.
  • Page 122 Problem solving • Load Xerox 4024 Dual Purpose, 24-pound paper (or a high quality equivalent). • Verify that the bank regularly adjusts and cleans the reader sorter to the specifications set by the manufacturer. • Make sure that the reject rate is based on a statistically valid number of documents and reader sorters.
  • Page 123 Problem solving The following table identifies typical problems that are associated with different reject rates. Note that the source of the problem can include the reader sorter itself.

  • Page 125: Document Damage

    Problem solving Document damage Even subtle damage can ruin a document. Characters may be cut by sharp edges within the reader sorter. If there are wrinkles in the document, the reader sorter may be causing its own errors. Leading edge damage in the reader sorter is a common problem with short-grain documents.
  • Page 126: Job History Or Results

    Problem solving Job history or results Ask the following questions: • Is this the first time that this job has been run? • What happened on the other occasions? • Is the current result an exception? Compare the documents with previous samples Keep a record of base information and samples of previously printed jobs to help isolate and resolve recurring problems.
  • Page 127: Test Patterns: Alternative To Reader Sorter Testing

  • Page 128: Verifying Problem Resolution

    Problem solving All Xerox MICR printers incorporate MICR diagnostic test patterns. These forms combine the needs of service diagnosis and call closeout with MICR problem analysis and escalation. You may want to use separate test pattern files to verify individual PostScript, PCL, and LCDS fonts. The MICR line on these forms is in the correct format for reader sorter testing.
  • Page 129: Security

    MICR printing system is of special sensitivity, because outputs often include negotiable documents. The key to security of a Xerox MICR printing system is to control access to critical and sensitive files, and to keep track of the legitimate use of these files through audit procedures. The critical files vary depending on check printing application implementation.
  • Page 130: Physical Security

    • Use of document security features that protect against both alteration and duplication Physical security The primary aspects of physical security for the Xerox MICR printing systems include the following. Restricting physical access Access to printing The most important security feature is control of access to check system printing facilities and to the MICR printing system.
  • Page 131: Securing Paper Stocks

    Security Securing paper stocks The ability of the Xerox MICR printing system to print a form, signature, logo, and MICR line on a check at the same time as the variable data eliminates the security problems resulting from keeping a supply of preprinted checks in storage.
  • Page 132: Responsible Presence

    Logon levels Several Xerox MICR printers provide some level of logon or password security as standard or an option. Many systems have a logon level at which the user files can be restricted from all of the other levels so they cannot be edited, deleted, or used by other jobs.
  • Page 133: System Commands

    Audit control processes The primary audit function for Xerox MICR printers is to identify the processes or procedures that could compromise control of valued items. The auditor then finds ways to stop that loss of control.
  • Page 134: Samples

    Security The operator captures and accounts for all jam scrap and makes sure that no missing or duplicate checks result from the jam. The audit process works only if all of the sheets in the jam are discretely identified. These sheets should be considered part of the output for the job until the auditor is satisfied that the job has successfully completed.
  • Page 135: Tampering Methods

    Security Tampering methods There are several methods by which data on a check may be altered. The security papers on which negotiable documents are printed are designed to thwart these forms of tampering. Chemical tampering Many inks can be affected by particular chemicals, making chemical alteration of checks possible.
  • Page 136: Modifying Printed Checks

    Security • Selecting checks with a structured background pattern. This type of background accentuates the pattern change that results from tampering. Random check backgrounds may camouflage damage due to alteration. • Using “fugitive” inks, which run when a solvent is applied. A water soluble ink shows any attempt to loosen and remove paper fibers attached to a dry ink image.
  • Page 137: Cold Pressure Fix

    Security Fabric ribbon inks also soak into and around paper fibers. How much the inks soak in depends on how new the ribbon is. As the ribbon is reused, ink levels are depleted and the image does not bond as much to the paper. At this point, the image is easier to remove.
  • Page 138: Preventing Tampering

    The numeric field takes second place in legal precedence. The ability of the Xerox MICR laser printer to use special fonts, or fonts on a special background field, makes check modification very difficult. However, these fonts and background also make check processing more difficult.
  • Page 139: Safety Papers

    Security Safety papers Safety papers have a background that makes alteration easily visible. Scenic backgrounds or a repetitive pattern, such as a logo, are some examples. Safety papers that consist only of a patterned background are not foolproof. Many financial documents are produced on a base paper, on which a safety pattern is printed using stable inks.
  • Page 140: Amount Limit Statements

    Some countries may require that the statement be printed in more than one language. The Xerox printing system allows selection of small or compressed fonts to create space for the statements on the document.
  • Page 141: Microprint

    Security Microprint Microprint is extremely small text that, unmagnified, looks like part of the check design. When magnified, it is a readable text message. Microprints are very effective in preventing check duplication because of their small image size. Like safety patterns, microprints are usually applied using conventional wet ink technologies before the stock is used in the MICR printing system.
  • Page 142: Dataglyph

    Security Dataglyph™ Dataglyph is a new technology that permits duplicate encoding of all variable data in a covert but machine readable form. Dataglyphs appear to be shaded areas. Under close examination, patterns of left and right tilted diagonal lines can be seen.
  • Page 143: Embezzlement

    Security • Use a check that is protected. Many checks are printed on paper that has a chemical coating or has chemicals in its internal composition that react visually when solvents are applied or erasure is attempted. • Avoid using correctable typewriter ribbons. The same feature that let you easily remove typing mistakes enables a criminal to change the information on a check.
  • Page 144: Stolen Checks

    Security Stolen checks Blank checks may be removed from the premises by employees, delivery personnel, service technicians, customers, emergency personnel, or burglars. Missing checks may not be noticed immediately. In some cases, checks are intentionally thrown away without secure disposition. Stolen checks that are successfully passed are the responsibility of the account holder, and the losses are usually not recovered.
  • Page 145: Cost Considerations

    Security • Select a good check design. Review the design features that are effective against counterfeiting. Consult with the security officer at your bank and with your check supplier when considering specific protections. • Install reconciliation procedures. Make sure that accounts are posted promptly, and that bank statements are balanced immediately upon receipt.
