Issue Description: 

Local USB connections to a Microsoft Windows computer allow firmware updates via the USB Flash Utility.

 

Before you Begin:

Do the following before updating printer or MFP firmware:

  • Download the .zip file to an easy-to-find location such as your Windows Desktop.
     
  • Uzip the file to your Windows Desktop or a destination directory that is easy to locate.
     
  • Power off your printer and then back on to clear any error messages and to bring the printer back to READY.
      
  • Verify your USB connection to the printer, and make sure the printer is recognized by the USB host controller.
     

Note: You will see connection notifications in the notification area of your task bar, and Microsoft's Add New Hardware Wizard may appear. Cancel these notifications.

  

USB Flash Utilities:


USB Flash Utility has a GUI-based interface which shows a progress bar.

 

Procedures:
