OCR Programming 11 - 31
OCR Redundancy
Parameter # 1770 (SSI # F8h 06h EAh)
This option adjusts the number of times to decode an OCR text string before transmission. There are three
levels of OCR decode redundancy. There is an inverse relationship between the redundancy level and OCR
decoding aggressiveness. Increasing the level of the redundancy can reduce OCR scanning aggressiveness,
so select only the level of redundancy necessary.
• OCR Redundancy Level 1: This default setting allows the scanner to operate in its most aggressive
state while providing sufficient accuracy in decoding most in-spec OCR text strings.
• OCR Redundancy Level 2: This setting eliminates most misdecodes while maintaining reasonable
aggressiveness.
• OCR Redundancy Level 3: Select this option with greater redundancy requirements if OCR
Redundancy Level 2 fails to eliminate misdecodes.
