CHAPTER 2 INSTALLATION AND BASIC OPERATION
5.2.4 + & - switch
If you press the + or – switch when the printer is in the on-line state (READY), it turns off-line
and the LCD displays the menu.
(1) To display menus in the current mode
If you press the + or – switch when the printer is in the on-line state (READY), it goes
off-line and the LCD displays the current mode.
You can enter other menus in the current mode by pressing the + or – switch. Pressing
the + or – switch allows you to scroll forward or backward through the menus and settings
on the display. Press or hold the switch until the display shows the desired item.
(8) To set numbers
There are two ways to input numbers. You can use the + or – switch to scroll up or down
to set them one at a time, or you can enter them. If you hold down the + or – switch, the
display scrolls up or down faster.
5.2.5

Set switch

If you press the Set switch when the printer is in the on-line state (READY), it goes off-line and
the LCD displays the current mode.
Pressing the Set switch allows you to set the selected menu or the default number. After
changing the menu or the number, an asterisk appears briefly on the right and the mode
returns to the previous menu.
5.2.6

Back switch

If you press the Back switch when the printer is in the on-line state (READY), it goes off-line
and the LCD goes to the menu display.
Pressing the Back switch allows you to return to the previous level from the current menu level.
The Back switch also allows you to select the next digit while inputting numbers. When the
leftmost digit is selected, the Back switch allows you to go up one level in the menu. When a
menu or number without an asterisk (Set switch not pressed) is selected, the Back switch
allows you to return to the previous menu level with the original setting unchanged.
NOTE:
When you press the Set switch to select a setting, an asterisk appears briefly at the end of the
display. Since the asterisk indicates the selection, you can easily find the current setting as
you scroll through the display.
5.3

LCD Display

The display shows the current printer status. When you use the control panel switches, the
display will change.
When you take the printer off-line, the display changes to show the selected emulation.
If any problems occur, the display shows the corresponding operator call, error, or service call
message to prompt you to take an action. For more information about these messages, see
CHAPTER 6 ‘TROUBLESHOOTING’.
