Uninstalling Windows driver
The Windows driver should be removed when the latest Windows driver is to be installed again or the existing driver is duplicated or installed incorrectly.
You should remove the Windows driver from “Add/Remove Programs” menu.
If you remove only the printer driver without removing the fax driver, there might an issue in reinstalling Windows driver as the printer driver is not removed properly. Also the settings for the existing driver may be applied to the newly installed driver.
If you cannot find the Windows driver in “Add/Remove Programs” menu or have difficulty in uninstalling it, refer to the troubleshooting section of Uninstalling Windows driver.
