Sample check digit calculation #2

Assume the following:

Image Address = 123.45.678.912

Attributes = 46231546231

Constant 1 = 7

Constant 2 = 10

Divisor = 11

Left/Right = Right

LUT Status = Yes/on

Lookup Table = abcdefghijk

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).
