To scan a barcode:
- Point the scanner's window at the barcode.
- Press the trigger button to activate the scan beam.
- Ensure the beam covers the entire barcode. A successful scan is usually indicated by an audible beep and/or LED indicator.
3.2 RFID Scanning
The MJ-2023 supports Ultra-High Frequency (UHF) RFID scanning with frequencies including 920-925MHz, 902-928MHz, and 865-868MHz.
The scanner features a mode switching button to toggle between different scanning modes:
- RFID Mode: For scanning RFID tags.
- Barcode Mode: For scanning 1D/2D barcodes.
- Barcode + RFID Mode: Allows scanning of both barcodes and RFID tags.
Refer to the on-screen instructions or the scanner's display (if available) for visual cues on the current mode.
3.3 Customization and Settings
The barcode reader offers over 300 configuration options to tailor its functionality:
- Prefix/Suffix Codes: Add custom characters before or after scanned data.
- Character Deletion: Remove starting or ending characters from scanned data.
- Keyboard Keys: Integrate keyboard keys or combinations (e.g., TAB, CR&LF) into the scanning operation for automated data entry.
- Sound and Vibration: Enable or disable audible beeps and vibration feedback.
- Scanning Modes: Switch between instant upload (data sent immediately) and storage mode (data stored internally and uploaded later).
These settings are typically configured by scanning specific programming barcodes found in the full user manual (if provided separately) or through companion software.
4. Maintenance and Durability
The Symcode MJ-2023 is built with durability in mind to ensure long-lasting performance in demanding environments.
4.1 Anti-shock Design
The scanner features an anti-shock design, allowing it to withstand multiple drops from a height of 2.5 meters (approximately 8 feet) onto concrete surfaces without compromising functionality.
4.2 Cleaning and Care
- Exterior: Wipe the scanner's exterior with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Scan Window: Gently clean the scan window with a lint-free cloth to ensure optimal scanning performance.
- Storage: Store the scanner in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
4.3 Environmental Protection
The scanner has a sealing grade of IP65 and IP67, indicating protection against dust and water ingress, making it suitable for various industrial settings.
5. Troubleshooting
If you encounter issues with your Symcode MJ-2023 scanner, try the following troubleshooting steps:
- Scanner not connecting: Ensure the scanner is charged. For wireless connections, verify the dongle is properly inserted (2.4GHz) or Bluetooth is paired correctly. For wired connections, check the USB cable.
- Scanner not reading barcodes: Ensure the barcode is clean and not excessively damaged. Check that the scanner is in the correct mode (Barcode mode for barcodes, RFID mode for RFID tags). Adjust the distance and angle to the barcode.
- No data transmitted to computer: Confirm the scanner is successfully connected to your device. Test with a simple text editor to rule out application-specific issues.
- Incorrect data output: Review the scanner's configuration settings for any custom prefixes, suffixes, or character deletions that might be altering the data.
- Short battery life: Ensure the scanner is fully charged. If battery life significantly degrades over time, contact support for assistance.
