OCR Quiet Zone
Parameter # 695 (SSI # F1h B7h)
This option sets the OCR quiet zone. The scanner stops scanning a field when it detects a sufficiently wide
blank space. The width of this space is defined by the End of Field option. Used with parsers that tolerate
slanted characters, the End of Field count is approximately a count of 8 for a character width. For example,
if set to 15, then two character widths are an end of line indicator for the parser. Larger end of field
numbers require bigger quiet zones at each end of text line.
To set a quiet zone, scan the following barcode, then scan a two-digit number using the numeric keypad in
<em_Emphasis><bl_blue>Appendix G, Numeric Barcodes. The range of the quiet zone is 20 - 99 and the
default is 50, indicating a six character width quiet zone.
OCR Template
Parameter # 547 (SSI # F1h 23h)
This option creates a template for precisely matching scanned OCR characters to a desired input format.
Appropriate OCR template needs to be set before using OCR features.
To set or modify the OCR decode template, scan the <bl_blue><em_Emphasis>OCR Template barcode,
and then scan barcodes on the following pages that correspond to numbers and letters to form the
template expression. Then scan
End of Message. The default is 99999999 which accepts OCR strings only
containing eight digits.
