Back button

If you press the Back button when the printer is on-line (READY), it
goes off-line and the LCD goes to the menu.
Pressing the Back button allows you to return to the previous level
from the current menu level.
The Back button also allows you to choose the previous digit while
setting numbers.
When you select a setting and it does not have and asterisk (Set
button was not pressed), the Back button allows you to return to the
previous menu level with the original setting unchanged.
When you press the Set button to choose a setting, an
asterisk appears briefly at the end of the display. Since the
asterisk shows what you have chosen, you can easily see the
current settings as you look through the display.
