â— Barcode scanner is not accurate enough. During the production process, the density is 1 mil, 2 mil, 3 mil, 4 mil, 5 mil, etc. When bar code recognition is performed, the reading accuracy of the bar code scanner must be higher than the density of the identified bar code, such as Scanning a 3 mil bar code must use a scanner with a density of 2 mils or 3 mils.
â— Barcode scanner code system does not open bar code scanner at the factory, in order to optimize the decoder's decoding performance, some of the commonly used code system is locked, when your bar code is just within the lock code system, It will be unrecognizable, you only need to use the setup manual to open the code system.
â— The barcode scanner setting is confusing. During the process of using the barcode scanner, the barcode scanner setting is confusing and the barcode cannot be recognized due to scanning to some special setting barcodes. You can restore the factory-set barcode by setting the manual. Process it.
â— Barcode scanner hardware fault Barcode scanner hardware failure caused by the barcode is not recognized (based on the probability of failure from high to low):
1 barcode scanner data cable is damaged (can be replaced);
2 barcode scanner scan head failure (repair or replacement);
3 Barcode scanner decoder board failure (repair or replacement)
4 Barcode scanner power board failure (repair or replacement)
â— The bar code quality is abnormal:
1 Bar code is distorted, bar code is a relatively precise symbol system, and each code system has a corresponding ratio. In the process of bar code making, the bar code can be freely deformed, and the result that bar code cannot be recognized will occur, especially using Coreldraw, etc. When the graphics software makes barcodes.
2 Bar code strips are broken vertically, which usually occurs when bar code labels are printed using bar code printers. The main reason is that the print head breaks and the ribbon wrinkles.
3 The width of the blank area of ​​the barcode is not enough. The left and right margins of the barcode must be at least 10 times the width of the narrow strip.
4 Bar code and empty color match, the bar code reading depends on the color of the bar, the high reflectivity color will be recognized as empty, the low reflectance color will be recognized as a bar, in general, the white bar blue The bar code can be read, the bar code of the red bar on the red bottom can be read, and the bar code of the yellow bottom purple bar can be read. Generally, the bar code of the red bar on the white background cannot be read, and the bar code of the black bar on the blue bottom cannot be read.
â— Barcode identification matching problem: Barcode scanner and field light source do not match Barcode scanner has a more important parameter, which has been less concerned. This parameter is light resistance. For bar code recognition, attention should be paid to spot light source and bar code scanning. Matching the light resistance of the device, otherwise it will cause unrecognized conditions, such as scanning some screen barcodes more prominently.
â— It is very important that the barcode scanner does not match the barcode carrier. The following lists several common carriers that match the scanner:
1 metal engraving barcode, barcode scanner that requires DPM characteristics;
2 PET and other brighter surfaces, need to use a bar code scanner such as laser;
3 The surface of the barcode carrier is covered with glass or film, and a bar code scanner with high power of the light source is needed;
4 Bar code carrier If you need to move, high speed or low speed, you need to use a barcode scanner with matching speed.
â— The barcode scanner does not match the barcode system. Some industries have different code systems. For example, the domestic Longbei code cannot be read by the commonly used barcode scanner. It must be matched with a dedicated barcode scanner. .
Scanner does not recognize barcode factors
For barcode guns, barcodes are generally not scanned. Except for the reason that the barcode scanner itself may not be read due to insufficient accuracy, incorrect settings, hardware failures, etc., it is often possible that barcode labels are abnormal or barcodes. The problem of identifying problems such as mismatching is summarized here. Xiaobian here summarizes the reasons why several scanners cannot recognize barcodes:
