Sample check digit calculation #2
Assume the following:
Image Address
=
Attributes
=
Constant 1
=
Constant 2
=
Divisor
=
Left/Right
=
LUT Status
=
Lookup Table
=
Then the check digit calculation would be:
1. Set up the equation:
Check Digit = 10 - [Calculation 1] + 7
Calculation 1 = (2 x 1) + (1 x 3) + (9 x 2) + (8 x 6) + (7 x 4) + (6 x 5) +
(5 x 1) + (4 x 3) + (3 x 2) + (2 x 6) + (1 x 4)
2. Calculate the value of the fraction:
168 + 7 = 15.91
3. Apply the Left/Right parameter:
15.91
= 5 if Left is specified
15.91
= 9 if Right is specified
In this example, 9 is used.
4. Complete the calculation:
10 - 9 = 1
5. Apply the Lookup Table values:
1 cross references to B
In this example, 1 is the check digit. The Image Address printed by the
Document Printer would be: 123.45.678.912B.
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).
