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 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 Alphanumeric Barcodes.
4. Scan End of Message on page 319.
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 Default Parameters on page 59 and re-program the scanner.
