OCR Maximum Characters
Parameter # 690 (SSI # F1h B2h)
To select the maximum number of OCR characters (including spaces) per line to decode, scan the
following barcode, then scan a three-digit number between 003 and 100 using the barcodes in
<em_Emphasis><bl_blue>Appendix G, Numeric Barcodes representing the number of OCR characters to
decode. Strings of OCR characters greater than the maximum are ignored. The default is 100.
OCR Subset
Parameter # 686 (SSI # F1h AEh)
Create an OCR subset to define a custom group of characters in place of a preset font variant. For
example, if scanning only numbers and the letters A, B, and C, create a subset of just these characters to
speed decoding. This applies a designated OCR Subset across all enabled OCR fonts.
To set or modify the OCR font subset:
1. Enable the appropriate OCR font(s).
2. Scan the OCR Subset barcode.
3. Scan numbers and letters to form the OCR Subset from <em_Emphasis><bl_blue>Appendix H,
Alphanumeric Barodes.
4. Scan <bl_blue><em_Emphasis>End of Message on page H-7.
To cancel an OCR subset, for OCR-A or OCR-B, scan OCR-A variant
Full ASCII, or OCR-B variant Full
ASCII
.
For MICR E13B or US Currency Serial Number, create a subset which includes all allowed characters in
that character set, or scan an option from the <bl_blue><em_Emphasis>Default Parameters on page 6-5
and re-program the scanner.
