for the calculation. By default, the check character computation is unweighted,
but the image scanner also supports two weighted modulo 10 checking
schemes.
Example:
To program a modulo 11 check character, you would enter the
following 11 characters in order:
0123456789X
Also enter the OCR template:
dddddddc
Enable the OCR-A font, then scan the following string:
6512351X
The image scanner performs the following check character computation:
(6 + 5 + 1 + 2 +3 + 5 + 1 + X) modulo 11 = 0
Since the result is zero, the message is considered to be valid, so the reader
outputs the message: 6512351
Programming a User-Defined Check Character
1. Scan the Enter OCR Check Character bar code, below.
2. Enter the characters in order. For each character, look up the corresponding
hex value from the Code Page Mapping of Printed Bar Codes on page A-7.
Use the Programming Chart on the inside the back cover of this manual to
scan the two symbols for each hex value.
3. Scan the Save bar code on the inside back cover.
Example: To program the modulo 11 check character from example #8 on
page 9-9, enable the OCR-A font. Scan the Enter OCR Check
Character bar code on page 9-9, then scan the following hex values
in order:
3031323334353637383958
After you enter all the desired hex values, scan the Save bar code on the
inside back cover of this manual.
