Format specifications using E13B
E13B character set
Generic MICR Fundamentals Guide
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. If the clear band is not at the bottom
of the sheet, keep 1/8 inch/4 mm below the clear band free of
printing.
There are two types of characters in the E13B font: numbers and
symbols.
E13B numbers
The E13B font numbers are illustrated below:
E13B symbols
The E13B font has the following four symbols.
On-Us symbol
This symbol tells the reader sorter that the next few numbers
identify the account. Because the issuing institution determines
the content of the On-Us field, the bank branch on which the
check is drawn may also be indicated.
On larger business size checks, the On-Us symbol is also used
to define a field on the left end of the check. This optional field,
called the Auxiliary On-Us field, frequently contains a multiple
digit serial number.
