Custom Check Digit
This option determines the check digit algorithm to be used when a
custom check digit is calculated.
NOTE: If a standard check digit algorithm is desired, specify the desired
algorithm during Image Address print definitions within each mode
setup.

The check digit is used to ensure the integrity of the Image Address.
All parameters in the algorithm are user-definable, offering a high degree
of flexibility.
During filming and/or scanning, the microfilmer or scanner assigns each
document an Image Address. The Image Address is used to compute the
check digit. The check digit then becomes the rightmost digit of the Image
Address (therefore, the Image Address must be defined as having a
maximum of eleven (11) characters).
NOTE: Because only one position is reserved, the check digit defaults to
zero when the following conditions occur:
• The Lookup Table is used and the check digit is greater than
ten (10).
• The Lookup Table is not used and the check digit is greater
than nine (9).
