Setup
- Unpack the Scanner: Carefully remove the MS320 scanner, USB cable, and any included documentation or companion CD from the packaging.
- Connect to Host Device: Insert the USB connector of the provided cable into an available USB port on your compatible device (Laptop or Desktop PC). The scanner is powered via the USB connection.
- Driver Installation (if necessary): For most modern operating systems, the MS320 is a plug-and-play device and drivers will install automatically. If prompted, or if the scanner does not function immediately, insert the companion CD (if included) and follow the on-screen instructions to install the necessary drivers or software. Alternatively, visit the Unitech official website for the latest drivers.
- Verify Connection: Once connected, the scanner's LED indicator may illuminate or flash, indicating it is powered on and ready for operation.
Operating Instructions
The Unitech MS320 is designed for straightforward barcode scanning. Follow these steps for optimal performance:
- Prepare for Scanning: Ensure the scanner is connected to your host device and the application where you intend to input barcode data (e.g., a text editor, inventory software) is active and ready to receive input.
- Aim and Scan: Hold the scanner with the scanning window facing the barcode. Position the scanner so that the red scanning line (emitted when the trigger is pressed) crosses the entire barcode.
- Trigger Scan: Press the trigger button on the scanner. The scanner will emit a red scanning line and attempt to read the barcode.
- Confirmation: Upon a successful scan, the scanner will typically emit an audible beep and/or the LED indicator will flash, and the barcode data will appear in your active application. If no confirmation is received, adjust the scanner's position and try again.
The MS320 is capable of reading standard 1D barcodes and PDF420 symbologies.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your Unitech MS320 scanner.
- Cleaning the Scanning Window: Regularly clean the scanning window with a soft, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaner. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the window.
- General Cleaning: Wipe the exterior of the scanner with a soft, dry cloth.
- Environmental Protection: While the MS320 is environmentally sealed against moisture and dust, it is recommended to avoid exposing the scanner to extreme temperatures, direct sunlight, or excessive humidity. Do not submerge the device in liquid.
- Cable Care: Inspect the USB cable periodically for any signs of damage, such as fraying or kinks. Replace the cable if damage is observed to prevent connectivity issues.
Troubleshooting
If you encounter issues with your Unitech MS320 scanner, refer to the following common troubleshooting steps:
| 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 host device. Try a different USB port or a different host device. |
| Scanner does not read barcodes. | Incorrect aiming, damaged barcode, or unreadable barcode type. | Ensure the scanning line covers the entire barcode. Check if the barcode is damaged or poorly printed. Verify that the barcode type is supported (1D barcodes and PDF420). Ensure drivers are correctly installed. |
| Barcode data appears incorrectly. | Keyboard layout mismatch or software configuration issue. | Check your computer's keyboard language settings. Refer to the companion CD or Unitech's website for programming guides to configure scanner settings if necessary. |
| LED indicator not functioning. | Power issue or internal fault. | Verify power connection. If the scanner is otherwise functioning, this may indicate a minor issue. If the scanner is not functioning at all, refer to "Scanner does not power on" solution. |
