7156 Owner’s Guide Commands

If both of these searches fail to produce the check serial number, extract the

whole account number field from between the rightmost transit symbol and the

rightmost “on us” symbol. A three, four, or five digit number to the right of the

rightmost transit symbol, separated by a space or a dash from the rest of the

account number is the check serial number.

txxxxxxxxxt cccc xxxxxxxxo

txxxxxxxxxt cccc-xxxxxxxxo

txxxxxxxxxt cccc xxxxxxxxo xx

If all of these searches fail to produce the distinct check serial number, and the

check serial number field has been specified in the parsing parameter string

options, no check serial number will be returned. If it is imbedded within the

account number field, it will be returned as part of that variable length field.

Exceptions

Some banks print the check serial number in a location which cannot be

electronically distinguished without specific exception information, although it

can be visually distinguished because it is repeated in the upper right corner of

the check. For these cases, the printer can hold up to nine exceptions for specific

banks in its non-volatile memory (NVRAM), which is accessed by the read and

write NVRAM commands. The specific bank is picked out by its transit number,

and the firmware will look in the exception table for a transit number match

before looking in the normal check serial number locations.

In this example, without an exception table entry, the firmware would always

pick the rightmost four digit number as the check serial number following rule

two above. The bank with the three digit check serial number and the four digit

extension after the “on us” symbol would need to be exceptionally recognized:

txxxxxxxxxt ccc-xxxxxxxxxxoxxxx

txxxxxxxxxt xxx-xxxxxxxxxxocccc

In this example, without an exception table entry, the firmware would not be able

to pick out the check serial number because it is not separated from the rest of the

account number:

txxxxxxxxxt ccccxxxxxxxxxxo

In this example, without an exception table entry, the firmware would not be able

to pick out the check serial number correctly, because it is imbedded within the

rest of the account number:

txxxxxxxxxt xxx-ccc-xxxxxxxxxxo
