3. Opsætningsvejledning
- Pak enheden ud: Carefully remove the MJ-1090 barcode scanner module from its packaging.
- Choose Connection Type: The MJ-1090 supports Type-C, 4Pin 1.5, and standard USB female port connections. Select the appropriate cable for your host device.
- Opret forbindelse til værtsenhed:
- For Type-C connection: Plug the Type-C cable into the scanner module and your smartphone or compatible device.
- For USB connection: Connect the USB cable to the scanner module and an available USB port on your computer or host system.
- For 4Pin 1.5 connection: Use the specialized 4Pin 1.5 cable to connect to compatible embedded systems.
- Plug & Play-betjening: For most computer connections (USB/Type-C), the device is plug-and-play and does not require additional driver installation. The operating system should automatically recognize the scanner.
- Bekræft forbindelsen: Once connected, the scanner should emit a short beep or show a status indicator (if available) to confirm it is ready for use.

4. Betjeningsvejledning
The Symcode MJ-1090 is designed for straightforward barcode scanning. Follow these steps for optimal performance:
- Placering: Hold the scanner module so that its scanning window is directed towards the barcode.
- Scanningsvinkel: Ensure the barcode is within the scanner's field of view. The MJ-1090 supports a scanning angle of up to 80 degrees, allowing for flexibility.
- Scan Activation: The scanner typically operates in an automatic detection mode, meaning it will activate its laser and attempt to read a barcode when one is presented within its scanning range.
- Successful Scan Indication: Upon a successful scan, the module will emit a buzzer sound, indicating that the barcode data has been captured and transmitted to the connected host device.
- Dataoverførsel: The scanned data will appear in the active application on your connected device (e.g., a text editor, POS software, or custom application) as if it were typed manually.
The scanner is capable of reading various barcode conditions, including those that are damaged, blurred, or displayed on digital screens, thanks to its advanced decoding algorithms.
5. Vedligeholdelse
- Rensning: Use a soft, dry cloth to clean the scanner's exterior and scanning window. Avoid abrasive cleaners or solvents that could damage the device.
- Opbevaring: Opbevar scanneren et køligt, tørt sted væk fra direkte sollys og ekstreme temperaturer, når den ikke er i brug.
- Håndtering: While the device features an anti-shock design, avoid unnecessary drops or impacts to prolong its lifespan.
6. Fejlfinding
- Scanneren svarer ikke:
- Ensure the cable is securely connected to both the scanner module and the host device.
- Try connecting the scanner to a different USB/Type-C port or a different host device to rule out port or device issues.
- Genstart værtsenheden.
- Kan ikke scanne stregkoder:
- Verify that the barcode is clean and clearly visible.
- Juster afstanden og vinklen mellem scanneren og stregkoden.
- Ensure there is sufficient lighting, but avoid direct glare on the barcode.
- Check if the barcode type is supported by the scanner (MJ-1090 supports all common 1D and 2D codes).
- Scanned data is incorrect or incomplete:
- Ensure the barcode is fully within the scanning area.
- Try scanning the barcode multiple times.
- Check the settings of your host application to ensure it is correctly configured to receive barcode input.
