I have brother-mfc-j985dw and brscan4 installed. In simple-scan I’m getting the error message “Unable to start scan” and in skanlite I’m getting the error message “Invalid argument”. Does anyone know how I could go about fixing this?

Fixed with sudo brsaneconfig4 -a name=MFC-J985DW imodel=MFC-J985DW ip=
