Setup
Follow these steps to properly set up your AC/DC adapter:
- Verify Compatibility: Ensure the adapter's output voltage (12V) and connector type match your device's requirements. This adapter is specifically designed for Zebra MZ and iMZ Series Mobile Bluetooth Printers.
- Check Connector Tip: Confirm the adapter's tip is compatible with your device's power input port. The adapter features a small tip without an internal pin.
- Connect to Device: Carefully insert the adapter's DC output plug into the power input port of your Zebra mobile printer. Ensure a snug fit.
- Connect to Power Outlet: Plug the AC input prongs of the adapter into a standard wall power outlet (100-240VAC, 50/60Hz).
- Verify Polarity: The adapter is designed with a specific polarity. Ensure your device also uses the same polarity (center positive).
