6. Operating Instructions
6.1 Scanning Modes
The TEEMI T26 supports three scanning modes:
- Trigger Scan Mode: Press the trigger button to initiate a scan. Release to stop.
- Automatic Scanning Mode: The scanner automatically detects barcodes within its field of view and scans them without requiring a trigger press. This mode is typically activated when the scanner is placed in its intelligent stand.
- Continuous Scanning Mode: The scanner continuously emits a scan beam, scanning any barcode that passes through its field of view. This mode is useful for high-volume scanning.
6.2 Scanning Barcodes
The T26 can read various types of barcodes on different media, including printed labels and digital screens.
- 1D Barcodes: UPC/EAN, Code 128, Code 39, etc.
- 2D Barcodes: QR Code, Data Matrix, PDF417, Aztec Code, etc.
- Digital Codes: Scan barcodes directly from mobile phone displays, including digital coupon codes.
- Special Codes: Supports scanning of driver's licenses and IMB (Intelligent Mail Barcode).

Image: Examples of the scanner's wide application, including scanning digital coupon codes, driver's licenses, medical codes, and book barcodes. It also shows its ability to read reverse printed, distorted, colorful, UPC/EAN with supplementary, damaged, and reflective codes.

6.3 Hands-free Omnidirectional Scanning
When placed in the intelligent stand, the scanner can operate in hands-free omnidirectional mode, allowing for quick and efficient scanning from various angles without precise alignment.

6.4 Illumination and Aiming
The scanner employs highly visible red aimer dots for accurate targeting and flicker-free white soft illumination to reduce eye strain during prolonged use. The LED illumination can be adjusted as needed.

6.5 Haptic Feedback
The scanner provides haptic feedback (vibration) after a successful scan, which is particularly useful in noisy environments where audible beeps might be difficult to hear.
7. Advanced Features and Customization
7.1 Data Formatting
The scanner offers robust data formatting capabilities, allowing you to customize the output data:
- Add prefixes and suffixes to scanned data.
- Delete specific characters from scanned data.
- Enable or disable specific barcode types.
- Adjust sound settings.
- Set uppercase/lowercase output.
- Powerful driver's license data parsing feature.
Refer to the supplementary programming guide (if provided separately) for detailed instructions on configuring these settings using programming barcodes.
7.2 USB Modes Supported
The TEEMI T26 supports multiple USB communication modes to ensure compatibility with various systems and applications:
- USB HID (Human Interface Device): Standard keyboard emulation mode, where scanned data is input as if typed from a keyboard.
- USB Virtual COM Port: Emulates a serial port, allowing software to communicate with the scanner as a serial device. Drivers may be required for this mode on some systems.
- USB HID POS Mode: Optimized for Point-of-Sale systems.
8. Maintenance
Proper maintenance ensures the longevity and optimal performance of your scanner.
- Cleaning: Use a soft, clean, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe the exterior of the scanner. Do not use abrasive cleaners or solvents.

9. Troubleshooting
If you encounter issues with your TEEMI T26 scanner, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Scanner does not power on. | USB cable not properly connected or faulty USB port. | Ensure the USB cable is securely connected to both the scanner and the computer. Try a different USB port. |
| Scanner does not read barcodes. | Barcode damaged, poor lighting, incorrect scanning angle, or scanner not in correct mode. | Ensure barcode is clear and undamaged. Adjust lighting. Try different scanning angles. Verify scanner is in the correct operating mode (trigger, auto, continuous). Clean scanning window. |
| Scanned data is incorrect or incomplete. | Barcode not fully read, or data formatting settings are incorrect. | Ensure the entire barcode is within the scanning area. Check data formatting settings (prefixes, suffixes, character deletion) in the programming guide. |
| Scanner beeps but no data is transmitted. | Incorrect USB mode selected or application not ready to receive input. | Verify the USB mode (HID, Virtual COM) matches your system's configuration. Ensure the cursor is in the input field of your application. |
If the problem persists after trying these solutions, please contact TEEMI customer support.
