Using the host computer to update the MFP firmware over USB
Note: This procedure uses the program, USB Flash. USButil is a command line USB flash utility that can also
be used to update firmware from a host computer via USB. To use any USB flashing utility, the MFP must be
installed on the host computer so a USB virtual printer port can be established on the host computer. The virtual
printer port is needed so the host computer can communicate with the MFP.

2. Browse for flash file.
3. Select the MFP from the list of printers installed on the computer.
4. Press Start.
5. Repeat these steps for every file you are updating on the MFP.
