The plotter has to be in the so-called host-mode. If you want to change the plotter settings, you first have to switch on your device. Now please press the <-button on the panel. After the plotter has made its initialisation, please press the function button as long as you can see priority in the display. Now press the enter-key and then the ^-key. In the display you will now see Host. Press the Enter button for confirmation.
