Barcode Scanner Not Scanning? Common Issues and Easy Fixes
Having trouble with your barcode scanner? Can't scan barcodes correctly? This is a common issue in warehousing and inventory management, which can disrupt workflows and cause data errors. In this article, we'll explore the common causes of barcode scanner failures and provide solutions to help you get back on track.
Barcode Scanner Not Responding (No Light)
If your scanner isn't lighting up or responding, here are a few possible causes:
● Connection Issues: Double-check the connection between the wired barcode scanner and the computer. Make sure the cable is securely plugged in and not loose.
● Power Issues: Verify that your computer has sufficient power, especially using a USB port. Insufficient power can prevent the scanner from functioning correctly.
● USB Port Issues: Check if the computer's USB port works correctly. Try connecting the scanner to a different port.
● Scanner Damage: If the above checks don't resolve the issue, the scanner head or motherboard may be damaged, requiring repair or replacement.
Scanner Lights Up but Cannot Scan Barcodes Correctly
● Input Method Interference: Using a Chinese input method on your computer can cause incomplete barcode scans. Switch to English mode for accurate results.
● Incorrect Settings: Check your scanner's settings. If it doesn't support certain barcode types or is using default settings, it might fail to scan.
● Insufficient Scanner Precision: Standard scanners usually support resolutions of 5 mil, suitable for regular barcodes. If your barcode requires 3 mil precision, you'll need a high-resolution scanner.
Scanning Environment Considerations
The distance and angle at which you scan the barcode can also affect the scanning performance. Too close or too far can result in poor focus, while an angle that is not perpendicular can cause mirror reflections, hindering accurate reading. Maintain the optimal focus distance and ensure the scanner is perpendicular to the barcode.
Additionally, the quality of the barcode itself plays a crucial role. Poor quality barcodes can hinder recognition, such as:
● Poor Printing: Barcodes that are blurry, damaged, or low-contrast can't be scanned effectively.
● Quiet Zone Issues: If the barcode's quiet zone (the blank space around it) is too small or encroached upon by text, scanning accuracy will suffer.
We recommend using a high-performance handheld image scanner like the HPRT N160 2D handheld barcode scanner. It offers excellent decoding capabilities, supports 3mil high-resolution scanning, and can effectively read damaged or dirty barcodes and QR codes.
The HPRT N160 2D barcode scanner's long depth of field allows for effortless scanning at various distances. Its ergonomic design ensures comfortable use for extended periods, while the intuitive battery indicator provides real-time power status.
In short, the HPRT N160 is highly responsive, efficient, and durable - making it the ideal choice for logistics, warehousing, and healthcare applications.
Moreover, the design of barcode labels should be thoughtfully considered to avoid excessive information that complicates recognition.
The size and density of the barcode need to be optimized based on the performance requirements of the scanning device to prevent issues like barcodes being too small or dense, leading to scanning failures.
The reasons behind a barcode scanner failing to read barcodes correctly can be varied, ranging from device malfunctions to barcode design and label quality factors. By systematically checking hardware, software, barcode quality, and environmental conditions, and taking appropriate measures, you can effectively resolve the issues. Choosing high-performance equipment and conducting regular maintenance are also effective strategies for preventing problems.
