What do you do if your barcode scanner is underperforming?

由人工智能和领英社区提供技术支持

Barcode scanners are essential tools for warehouse operations, as they help you track inventory, speed up order fulfillment, and reduce errors. However, sometimes your barcode scanner may not work as well as you expect, causing delays, frustration, and inaccuracies. In this article, you will learn what to do if your barcode scanner is underperforming, and how to troubleshoot some common problems.

1 Check the battery level

The first thing you should do if your barcode scanner is underperforming is to check the battery level. A low battery can affect the scanner's performance, making it slower, weaker, or less responsive. If the battery indicator shows that the battery is low, replace it with a fresh one, or recharge it if it is a rechargeable model. You should also make sure that the battery contacts are clean and not corroded.

If your barcode scanner relies on batteries, take care of them to maintain their performance. Use high-quality, recommended batteries and replace them as needed. Charge the battery when it reaches a low level rather than letting it fully discharge. Avoid overcharging the battery, which can lead to reduced capacity. Store the scanner with the battery partially charged if it will not be used for an extended period. Replace the battery when it no longer holds a charge effectively, as trying to use a failing battery can lead to other issues.

Assess whether your current single-line barcode scanner is meeting the desired read rates (ideally 99.9% to 100%). If not, it’s time to re-evaluate your technology.

2 Clean the scanner lens

Another common cause of barcode scanner underperformance is a dirty scanner lens. Dust, dirt, fingerprints, or smudges can interfere with the scanner's ability to read the barcode, resulting in poor scans or no scans at all. To clean the scanner lens, use a soft cloth or a lens cleaner, and gently wipe the lens in a circular motion. Do not use abrasive or harsh materials, such as paper towels, alcohol, or ammonia, as they can damage the lens.

Dust, debris, and smudges can accumulate on the surface and scanner window of barcode scanners, impairing their ability to read barcodes accurately. To combat this, use a soft, lint-free cloth or specialized electronic cleaning supplies to remove dust, debris, and smudges that can impair the scanner's ability to read barcodes.

3 Adjust the scanner settings

Sometimes, your barcode scanner may underperform because the scanner settings are not optimal for the type of barcode you are scanning. For example, some scanners have different modes for scanning one-dimensional (1D) or two-dimensional (2D) barcodes, such as QR codes or Data Matrix codes. If you are scanning a 2D barcode with a 1D mode, the scanner may not recognize it. To adjust the scanner settings, consult the user manual or the manufacturer's website, and follow the instructions to change the mode, resolution, contrast, or other parameters.

Proper calibration is essential for barcode scanners to read barcodes accurately. Most modern scanners offer automated calibration routines. Follow the manufacturer’s instructions to calibrate your scanners regularly. Manufacturers release firmware and software updates to improve scanner performance, address software-related issues, and enhance compatibility with new systems. Stay informed about these updates and regularly update the associated software and firmware on your barcode scanner. Keeping your scanner’s software up to date ensures optimal functionality and minimizes the risk of compatibility problems.

4 Test the scanner on different barcodes

If you have checked the battery level, cleaned the scanner lens, and adjusted the scanner settings, but your barcode scanner is still underperforming, you should test the scanner on different barcodes to identify the source of the problem. Sometimes, the barcode itself may be damaged, faded, or distorted, making it hard for the scanner to read it. To test the scanner on different barcodes, try scanning barcodes from different sources, such as labels, receipts, or screens, and see if the scanner works better on some than others. If the scanner works well on some barcodes but not others, the problem is likely with the barcode quality, not the scanner.

5 Contact the manufacturer or supplier

If none of the above steps solve your barcode scanner underperformance issue, you may need to contact the manufacturer or supplier for further assistance. They may be able to provide you with more troubleshooting tips, technical support, or warranty service. You should have your scanner model number, serial number, and purchase date ready when you contact them. You should also describe the problem clearly and accurately, and provide any relevant information, such as the type of barcode you are scanning, the scanner settings you are using, and the steps you have taken to fix the problem.

Barcode scanners are vital for efficient and accurate warehouse operations, but they can sometimes underperform due to various reasons. By following these steps, you can troubleshoot your barcode scanner and restore its performance, or seek professional help if needed.
