MICR OPERATING PROCEDURES
The 4635MX LPS enables you to create machine-readable
documents using the standard E-13B font that supports 14
characters including numerals zero through nine, as well as the
following symbols:
• Transit There are two transit symbols in a MICR line. The
numbers between the transit symbols identify the
institution upon which the check is drawn, and
where the the document should be sent for
processing.
• Amount There are two amount symbols in a MICR line.
The numbers between the amount symbols are the
amount of the check. This amount is normally
added later by the bank.
• On-Us The On-Us symbol indicates that the numbers to
the left of the symbol are the account number.
The content of the On-Us field is determined by
the issuing institution. The bank branch the check
is drawn on may also be indicated.
You will recognize your account number, your
bank branch number, and probably the check
number. The check serial number appears typically
to the right of the On-Us symbol.
On larger business size checks, this symbol is also
used to define a field on the left end of the check.
This field, called the Auxilliary On-Us field, is
optional and frequently contains a multiple digit
serial number.
• Dash The dash is sometimes used as a separator within
the On-Us field, although reader/sorter
manufacturers discourage its use because of
detection problems. Some banks use the dash to
separate the bank branch number from the
account number.
Tools to check MICR output
The following tools can be used to determine whether a
document is within specifications or not:
• MICR Position and Dimension Gauge
• 8 Power (X) Comparator with MICR Grid
Note: Use the custom transfer assist blade on all 4635MX
systems running non-standard paper sizes to ensure acceptable
MICR line quality. Refer to the “Maintenance tasks“ chapter,
“Custom transfer assist blade“ section for information on the
transfer assist blade.
MICR Position and Dimension Gauge
The MICR Position and Dimension Gauge, shipped in a kit which
includes a small magnifying glass, allows you to compare the
Xerox MICR printer information to industry standards. You can
compare character spacing, horizontal and vertical alignment, and
check for voids (deletions) and spots.
The MICR Position and Dimension Gauge is printed on a thin
sheet of flexible plastic, which is attached to the bottom of a
