If you're using the supported characters surrounded by the "*" stop and start characters, chances are the problem is either the size of the barcode or the resolution of the printing. When you are trying to scan a barcode, the scanner has to be able to determine the thickness of the black bars and the spaces. The width of the narrowest bar in the barcode is called the "barcode density". Although the standard density that a normal scanner can read is .007-.012, your scanner may have different specifications. First, try putting the scanner about an inch off the paper. Then pull the trigger and start increasing the distance of the scanner head to the paper. If the barcode has the proper density, it should beep and the scanning light should go off by the time you reach about 12" away from the paper. If changing the scanning distance didn't work, try increasing the size of the narrowest bar - in other words, increase the size of the barcode overall. Your word processing or spreadsheet program has a default Font Size set at 10 to 12 points. This font makes the narrow bar quite small, less than the .007" minimum that most scanners require. Highlight the text and select a larger Font Size. We start at 26 point then make adjustments from there. When we first came out with the barcode font, most people were using dot-matrix or ink jet printers. If you are using either, know that you may have to make the barcode very big in order for the scanner to read it. As the barcode gets bigger, the distance from the code to the scanner will increase as well. Laser printers are best, but you can still use a dot-matrix printer successfully. non-laser printer, sometimes upgrading the paper quality can help. |
