Quality control
6-6 Generic MICR Fundamentals Guide
• Periodically (once for each filled output bin): Horizontal
position, vertical position, voids, spots, and MICR line
appearance
When a clinical test is running—which many banks require
before changing check production—the following additional
design factors should be checked to provide a representative
test:
• The Xerox printing system should be adjusted to
manufacturer specifications and operator maintenance tasks
performed regularly per the manufacturer's recommendation.
• Only paper stock that meets ANSI and Xerox requirements
should be used.
• A large group of documents should be generated, several
thousand at a time.
• Test documents must be fresh and undamaged.
• The test application should mimic the live data, but its
appearance should not resemble a negotiable document. The
form should represent the correct document size, MICR line,
and a unique serial number for each document for
identification purposes.
• The test application should be validated for skew, vertical
alignment, and character size. (Any change in job resources
may alter MICR quality parameters that do not normally vary.)
Specifications for testing
The following specifications apply only to MICR characters that
are printed within the clear band. Printing outside the clear band
area should follow standard xerographic specifications.
Note that most MICR line positional errors (horizontal, vertical,
skew, and character) are due to poor document design rather
than problems with the MICR printing system technology.
Horizontal position
To check horizontal positioning, place the check at the bottom of
the MICR Gauge with the right edge of the check lined up with
the right edge of the gauge. Place the right edge of the first
transit symbol on the left between the dotted lines in boxes 42
and 43 of the gauge (see the following figure).
