13 - 14 DS4308/DS4308P Digital Scanner Product Reference Guide
OCR Quiet Zone
Parameter # 695 (SSI # F1h B7h)
This option sets the OCR quiet zone. The digital 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 roughly 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 bar code, then scan a two-digit number using the numeric keypad in the
Advanced Data Formatting Guide. The range of the quiet zone is 20 - 99 and the default is 50, indicating a six
character width quiet zone.
OCR Bright Illumination
Parameter # 701 (SSI # F1h BDh)
When enabled, image contrast is improved for OCR scanning. Zebra recommends enabling this when the
OCR string is longer than 20 characters, and for applications with busy backgrounds such as check or VISA
reading.
