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 Character1.Scan the Enter OCR Check Character bar code, below.

Enter OCR Check Character

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.
