Amount Field; On-Us Field; Transit Field - Xerox 6100BD - Phaser Color Laser Printer Fundamentals

Document design

Amount field

The Amount is the first field on the right, located between
character boxes 1 and 12. When this field is used, position 12
contains the Amount field symbol, and positions 2 through 11
contain the actual amount. The amount is right-justified, and all
unused positions to the left are filled in with zeros.
The Amount field is usually empty when the document is printed;
the amount is added later by the bank. However, some
applications may add the Amount field while printing checks.

On-Us field

The second field from the right is the On-Us field, located
between character boxes 14 and 31. It follows a blank space at
position 13, which is a separator from the Amount field.
The On-Us field includes variable information from the banking
institution, including the account number. It contains the On-Us
symbol, at position 14 and 31 or 32.
To the left of the On-Us symbol, reading right to left as the reader
sorter does, are the account number, the bank branch number,
and the check number. The check serial number is typically to
the right of the On-Us symbol. Since the issuing institution
determines the content of the On-Us field, the bank branch on
which the check is drawn on may also be indicated. The last
position is usually followed by a blank in position 32.
The Dash symbol is sometimes used as a separator within the
On-Us field. This is not recommended, however, because the
dash is difficult to detect.

Transit field

The Transit field is located between character boxes 33 and 43.
The Transit symbol is located at positions 33 and 43. On a check
having four fields, like the one in figure 4-3, this field is second
from the left. However, shorter checks (such as personal checks)
do not have an Auxiliary On-Us field. In this case, the Transit
field is the farthest left of the three fields. The Transit field, like
the Amount field, is right-justified, with all unused positions to the
left filled with zeros.
