The Argox AS 8520 driver helps Windows recognize the device and communicate with it through the selected connection mode. Although sometimes grouped with printer downloads, the AS 8520 is a barcode scanner, so choosing the correct scanner driver or interface package is important for reliable setup.

Key Features

• Device recognition: Provides the software support Windows may need to identify the scanner or its communication interface.
• Application connectivity: Helps compatible inventory, checkout, and data-entry software receive scanned information when the required interface is configured correctly.
• Interface-specific support: Supports communication for the connection type covered by the downloaded package. Some keyboard-style USB modes may work with Windows’ built-in drivers instead.
• Windows setup options: When downloading for Windows 11, 10, 8, or 7, check the package documentation for your exact operating system and system architecture.

How to Install

1. Check your scanner and Windows version. Confirm that the device label identifies it as the Argox AS 8520. Open your Windows system information to determine whether you need a 32-bit or 64-bit package.

1. Select the appropriate download. Choose an Argox package that explicitly lists your model, connection type, and Windows version. Avoid installing a printer driver simply because the scanner appears in a printer category.

1. Prepare the installation files. Extract the download if it is compressed, then review any included setup instructions. Connect or disconnect the scanner’s receiver or base as directed by the package documentation.

1. Install the driver. Run the supplied installer and follow the prompts. If the package contains driver files without an installer, use Device Manager’s “Update driver” option to browse to the extracted folder.

1. Configure and test scanning. Select the appropriate interface mode using the scanner’s documentation, then test a barcode in a compatible application. If no data appears, check the connection, scanner pairing where applicable, and application input settings before reinstalling.

Common Issues and Fixes

• Driver install fails / no COM port appears: The AS 8520 may be in USB HID keyboard mode, so the virtual COM driver cannot bind. Scan the USB Virtual COM interface barcode in the Argox manual, reconnect the scanner, then reinstall the driver.
• Device not detected: Check Device Manager for an unknown USB/serial device. Try another USB port and a data-capable cable; avoid unpowered hubs. For RS-232, confirm the correct COM port and power supply.
• Version conflicts / wrong port: Uninstall older Argox or USB-serial drivers, remove hidden devices, reboot, and install the current package. Set the scanner’s COM port in your POS/scanning software and avoid duplicate COM assignments.
