Troubleshooting Code 39 Barcodes

The Code 39 barcode specification mandates that a beginning asterisk (*) and ending asterisk (*) are used as the first and last characters of barcode text. For example, if you wanted to format 1234 as a Code 39 barcode, you would type *1234* and then format it as Code 39. When Remark Office OMR recognizes this barcode, only the data is returned, in this case, 1234.

Space characters are not recognized in Code 39 barcode text. To use a space character, type an exclamation point (!). For example, if you wanted to format John Smith as a Code 39 barcode, you would type *John!Smith* and then format it as Code 39. When Remark Office OMR recognizes this barcode, only the data will be returned, in this case, John Smith.

Barcodes should be printed at a point size of at least 26. They should be scanned at a resolution of at least 300 DPI.

If you downloaded your barcode font from a website other than Gravic, the barcode proportions may be different, preventing the software from accurately reading the barcode once the size of the barcode has been adjusted to a large enough size. The font available for free download on the Gravic website has been tested to be accurate. Try using that font instead.
