"The Required FNC1 Was Not Found" Error

[Omron Forums Support]

<FNC1> is a "non-printable" special character reserved for GS1-compliant symbols when using Code 128, QR code or Data Matrix symbologies. It is what indicates that a symbol is a GS1-128 symbol, for example, rather than just a regular Code 128. If “GS1 General Specifications” is selected as the Application Standard on the “Setup” tab, and <FNC1> is not encoded in the first position of the code, the code will automatically be graded an “F” since it is not GS1 compliant (see bottom image). If the code is intended to be GS1 compliant, notify the originator that GS1 requires <FNC1> to be present at the start of the symbol. If you are not grading a GS1 barcode, change your Application Standard on the “Setup” tab to “ISO/IEC 15415/15416” or other appropriate Application Standard.
