  6. Observe the control panel and wait.
    The following should happen:
    • If the firmware on the USB Flash drive is different than what is on the printer, the firmware downloads to the printer. The printer then restarts and prints a printer configuration label. (If there is no firmware on the USB Flash drive or if the firmware version is the same, the printer skips this action.)
    • The printer downloads the files in the
      /files
       folder and briefly shows the names of the files that are downloading on the display.
    • The printer executes any files in the
      /commands
       folder.
    • The printer restarts and then displays this message:
      MIRROR PROCESSING FINISHED
  7. Remove the USB Flash drive from the printer.
