FAQs & Troubleshooting |
Check the kind of scanner driver installed by connecting the USB/ Parallel cable.
When you install the scanner driver by connecting the USB or Parallel cable, the full installation of the Brother original scanner driver may not have been completed and the windows built-in driver may have been installed instead. Since the built-in drivers only support the basic functions of the Brother machine, we recommend using the Brother original scanner driver.
Follow Step A to check if the Brother original scanner driver has been fully installed. If not, follow Step B to replace the installed driver with the Brother original scanner driver.
