How to Update Printer Firmware with the USButil (DOS-based) or USB Flash Utility (Windows GUI-based)

Document ID:SO4667

Usergroup :External


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.
