*Do not attempt to rotate the roller manually this would render the printer inoperable

      2. In succession, press callout 1 (left navigation arrow), THEN immediately press callout 2 (cancel) and release BOTH. The printer should now show the ready (home) screen
      3. callout image
      4. Press the “setup” icon, secondary service should be the first menu option
    2. For a LCD Control Panel:
