Common Barcode Scanner Problems And How To Troubleshoot Them
Efficiency is critical in today’s fast-paced business environment, and barcode scanners are crucial in maintaining smooth operations. These devices are indispensable for managing inventory in a warehouse, processing sales at a retail counter, or tracking assets in an office. However, like any technology, barcode scanners can sometimes have issues that disrupt workflow.
Each type has its own set of potential challenges, from handheld barcode scanner models to sophisticated wireless barcode scanners. But don’t worry — most problems have straightforward solutions you can implement without calling a technician. In this blog post, we’ll explore five of the most common barcode scanner issues and provide detailed, step-by-step troubleshooting guides to get your devices back up and running quickly.
1. Barcode Not Scanning
One of the most frustrating problems you might encounter is when your barcode scanner simply refuses to read codes. This issue can bring your operations to a standstill but often has simple solutions.
Problem: Your barcode scanner isn’t reading codes despite multiple attempts.
Solution:
1. Clean the scanner window using a microfiber cloth. If necessary, use a small amount of isopropyl alcohol.
2. Adjust your scanning technique:
● Hold the scanner 4–8 inches from the barcode
● Ensure the scan line crosses every bar in the code
● Try scanning at different angles
3. Check the barcode quality:
● If printed, ensure high contrast and no smudges
● For digital barcodes, increase screen brightness
4. Update scanner firmware:
● Visit the manufacturer’s website
● Download the latest firmware
● Follow installation instructions carefully
5. If issues persist, try scanning known good barcodes to isolate the problem
Remember, regular scanner maintenance can prevent many of these issues from occurring in the first place. Cleaning the scanner window is part of your daily routine to ensure optimal performance.
2. Intermittent Connectivity with Wireless Barcode Scanners
Wireless barcode scanners offer great flexibility but sometimes face connectivity issues. These problems can be particularly frustrating as they may occur sporadically, making them hard to diagnose.
Problem: Your wireless barcode scanners frequently disconnect or have an unstable connection.
Solution:
1. Check the battery level and replace if below 20%
2. Reduce interference:
● Move away from other wireless devices, especially those on 2.4GHz
● Avoid metal surfaces and physical obstructions
3. Repair the scanner:
● Put the scanner in pairing mode (usually by scanning a specific barcode in the manual)
● Ensure the receiver is in pairing mode
● Complete the pairing process as per the manufacturer’s instructions
4. Update both scanner and receiver firmware
5. If using Bluetooth:
● Clear all paired devices from both the scanner and computer
● Repair as if it’s a new device
6. Check for driver conflicts:
● Open Device Manager
● Look for yellow exclamation marks
● Update or reinstall problematic drivers
Following these steps, you can often resolve connectivity issues without professional intervention. However, if problems persist, consider the layout of your workspace to minimize potential sources of interference.
3. Slow Scanning Speed
When your handheld barcode scanner starts to lag, it can significantly impact your productivity. Slow scanning speeds can be caused by various factors, from simple settings adjustments to hardware issues.
Problem: Your handheld barcode scanner needs to be shorter to read each code.
Solution:
1. Adjust scanner settings:
● Access scanner configuration (usually through scanning unique barcodes in the manual)
● Increase scan rate or decrease redundancy checks
2. Check for interference:
● Dim bright lights directly over the scanning area
● Remove reflective surfaces near the scanner
3. Optimize barcode size and quality:
● Ensure barcodes are at least 1 inch wide
● Use high-quality printing for more precise lines
4. Clean scanner and check for physical damage:
● Use compressed air to remove dust from the interior
● Inspect for cracks or scratches on scanning window
5. Update scanner memory:
● Some scanners store scanned data clear memory regularly
6. If all else fails, consider upgrading to a newer model with faster processing
Improving your scanning speed can significantly impact efficiency, especially in high-volume environments. Remember to consider the importance of regular maintenance and optimal scanner settings.
4. Incorrect Data Entry
Nothing is more frustrating than realizing your barcode scanner has been entering incorrect data, potentially causing inventory discrepancies or billing errors. This problem can be particularly insidious as it might take time to be apparent.
Problem: Your barcode scanner must enter the correct data or additional characters.
Solution:
1. Check keyboard layout settings:
● Ensure the scanner is set to the correct country keyboard layout
● This setting is usually changed by scanning specific barcodes in the manual
2. Disable automatic enter key:
● If the scanner adds unwanted line breaks, turn off the auto-enter function
● Again, this is typically done through configuration barcodes
3. Clear scanner memory and reset to factory defaults:
● Scan the “Factory Reset” barcode in your manual
● Reconfigure necessary settings
4. Check for interference from other input devices:
● Disconnect other keyboards or input devices temporarily
● Test scanner in isolation
5. Verify data format settings:
● Ensure the scanner is set to the correct data format (e.g., UPC, EAN, Code 39)
● Adjust prefix and suffix settings if necessary
6. If the problem persists, contact the manufacturer for potential firmware issues
Regular audits of scanned data can help catch these issues early. Consider implementing a quality control process where random scans are manually verified for accuracy.
5. Battery Drain in Wireless Models
Battery life is crucial for wireless barcode scanner users. Frequent recharging or battery replacements can disrupt workflow and increase operational costs.
Problem: The battery in your wireless barcode scanners is draining too quickly.
Solution:
1. Implement a charging schedule:
● Charge scanners nightly, avoiding complete battery depletion
2. Adjust power settings:
● Reduce screen brightness if applicable
● Shorten auto-off time
● These settings are typically accessible through configuration barcodes
3. Check for stuck buttons:
● Ensure the scan button isn’t physically stuck, causing a constant wake
4. Update firmware:
● Newer firmware often includes power optimization
5. Replace the battery:
● If the battery is over two years old, consider a replacement
● Use only manufacturer-approved batteries
6. Monitor temperature:
● Avoid using or charging in extreme temperatures
● Ideal range is usually between 50°F to 95°F (10°C to 35°C)
Proper battery management can significantly extend the life of your wireless scanners. Consider investing in spare batteries or charging cradles to ensure you always have a charged scanner ready.
In conclusion, while barcode scanners are robust tools designed for heavy use, they occasionally face issues. Understanding these common problems and their solutions can minimize downtime and keep your operations running smoothly. Remember, prevention is often the best cure — regular maintenance, proper usage, and staying up-to-date with firmware can help avoid many of these issues altogether.
