OCR Reads Scored Above the Acceptance Threshold but Failed

Event:

Attempt to read SEMI OCR fails despite the score exceeding the accept threshold.

Probable Causes:

• Any of the OCR characters are below the Character Threshold.

• A SEMI checksum is not added to OCR character, but "SEMI" or "SEMI with Virtual" is specified for the checksum. 

  

Solution:

• Look at the score for every character in OCR and if any of them is below the "Character Threshold" then lower the "Character Threshold" value below that character's score.
• Try setting the checksum to "Virtual".
