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
Alphanumeric 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. Carefully
constructing an OCR template eliminates scanning errors.
To set or modify the OCR decode template, scan the OCR Template barcode, and then scan barcodes on the
following pages that correspond to numbers and letters to form the template expression. Then scan
