Turn off Windows protected print mode for the PC, then reinstall the Brother multifunction device and its Windows 11-compatible full driver/software package to restore scanning.
Turn off protected print mode
- Open Start → Settings → Bluetooth & devices → Printers & scanners.
- Scroll down to Printer preferences.
- Under Windows protected print mode, select Turn Off.
- Select Yes when prompted.
This is a computer-wide setting, not a setting activated separately for each printer. When enabled, it removes third-party print drivers and limits scanning on multifunction devices that are not compatible with the protected mode. Disabling it permits non-compatible devices and their drivers to be installed again.^1^
Security tradeoff: Turning this mode off reduces Windows print-system hardening and permits third-party printer drivers system-wide. Do this only if the Brother scanner is required, and install only the exact, signed driver package for your model from Brother’s official support site. Keep that software updated.
Reinstall the Brother device
Turning off the mode does not automatically restore a non-compatible printer or its deleted driver.^2^
- Go to Settings → Bluetooth & devices → Printers & scanners.
- Select the existing Brother entry and choose Remove, if it is still listed.
- Download Brother’s Full Driver & Software Package for the exact model, matching Windows 11 and the PC’s system type.
- Run the installer and reconnect or add the device when instructed.
- Restart only if the installer requests it; otherwise, test scanning through Brother’s scanning application or Windows Scan.
Microsoft’s driver guidance likewise recommends obtaining a compatible driver from the manufacturer when Windows cannot supply a suitable one, then reinstalling the device.^3^
A replacement should not be necessary if Brother provides a Windows 11-compatible scanner driver or full software package for your exact model. If scanning is still unavailable afterward, provide the Brother model number, Windows version shown by winver, connection type (USB or network), and any scan error message.
If “Turn Off” is unavailable
If the PC is managed and protected print mode was enabled through Group Policy or device management, Windows does not allow a standard user to disable it. Contact the administrator and request that the Configure Windows protected print policy be disabled or left unconfigured; do not attempt to bypass the policy.^1^^4^
If a compatible Mopria scanning method is available for this model, leaving protected print mode enabled provides the stronger security configuration. Otherwise, keeping it disabled is necessary while the legacy Brother driver is in use.
