Your Essential Guide to Zebra TC20/TC25 Mobile Computers: Troubleshooting, Maintenance, and Repair

The Zebra TC20 and TC25 mobile computers are designed to bring enterprise-grade features to small and medium-sized businesses. These devices are built for durability and are perfect for retail, hospitality, and light-duty field service. While robust, users may still encounter common issues. Knowing how to troubleshoot these problems, perform basic maintenance, and handle professional repairs is key to keeping your devices running smoothly and maximizing your investment.

Here are some of the most frequent problems users encounter and the simple steps to resolve them.

This is a common issue that can often be resolved with a few simple checks.

• Check the Battery: The TC20/TC25 has a non-removable battery. If the device is not turning on, connect it to a power source using the original Zebra charging cable or cradle. Check for any visible damage to the cable.
• Perform a Hard Reboot: If the device is frozen or unresponsive, press and hold the power button for approximately 10 seconds. This will force a reboot and can often resolve minor software glitches.
• Inspect Charging Ports: The USB-C charging port can accumulate dust or lint. Use a soft brush or a can of compressed air to gently clean the port. A blocked port can prevent the device from charging properly.

The integrated scanner is a core feature of the TC20/TC25. If it fails to read a barcode, it can disrupt your workflow.

• Clean the Scanner Window: A smudge or dirt on the scanner window is a frequent culprit. Use a soft, lint-free cloth to gently wipe the window.
• Check App and Settings: Ensure the application you are using has permission to access the scanner. Also, check the DataWedge application to make sure the correct barcode types (symbologies) are enabled. Some specialty barcodes may be disabled by default.
• Restart the Device: If the problem persists, a quick reboot can often reset the scanner driver and get it back to normal operation.

Performance issues can be frustrating, but they are often software-related.

• Close Unused Apps: Having too many applications running in the background can consume memory and slow down the device. Close any apps you are not actively using to improve performance.
• Clear Cache: Over time, an app's cache can become bloated, leading to performance issues. You can clear the cache for individual apps in the device's settings to free up storage space and improve speed.
• Check for Software Updates: Zebra regularly releases operating system and security updates that can improve performance. Make sure your device has the latest firmware.

Beyond basic troubleshooting, proper maintenance and professional repair are crucial to extending the life of your TC20/TC25.

Proactive care is the best way to prevent issues from ever occurring.

• Physical Cleaning: Use a soft, lint-free cloth to clean the screen and body. For more stubborn grime, a solution of mild soap and water applied to the cloth is safe. Do not use harsh chemicals like alcohol or ammonia, as they can damage the screen's protective coating and the device's seals.
• Proper Charging: Always use the original Zebra charger and cable. Using third-party accessories can lead to damage.

When troubleshooting fails, it's time to consider professional repair.

• Utilize an Authorized Service Partner: For any significant hardware issues, always use a Zebra Authorized Service Partner. These technicians are specifically trained to work on Zebra devices and use only genuine parts, ensuring the repair is done correctly and your warranty remains valid. Using an unauthorized repair service could lead to further damage and may void your warranty.
• Invest in a Zebra OneCare Service Plan: For businesses where device uptime is critical, a Zebra OneCare service contract is a highly valuable investment. These plans offer comprehensive coverage for a variety of issues, including accidental damage, and guarantee fast repair turnaround times. Having a OneCare plan provides peace of mind and eliminates unexpected repair costs.
• Back Up Data Before Repair: Before sending a device in for repair, always back up any critical data. While service providers take precautions to preserve data, a factory reset may be a necessary step to diagnose or fix an issue.

By following these guidelines, you can ensure your Zebra TC20/TC25 mobile computers remain reliable and high-performing assets that empower your workforce for years to come.
