If you press Back when the printer is in the on-line state, it goes off-line and
the LCD goes to the menu.
Pressing Back allows you to return to the previous level from the current
menu level.
Pressing
Back also allows you to select the previous digit while inputting
numbers.
When the leftmost digit is selected,
Back allows you to go up one level in
the menu.
When a menu or number without an asterisk (
Set was not pressed) is
selected, Back allows you to return to the previous menu level with the
original setting unchanged.
Notes
When you press Set to select a setting, an asterisk appears briefly at the end
of the display. Since the asterisk indicates your selection, you can easily find
the current settings as you scroll through the display.
