Using the Operator Panel

Figure 9. The Operator Panel
The operator panel is shown above. During the configuration process, you will use
the ↑SCROLL/MICRO , ↓SCROLL/MICRO , ENTER, and RETURN keys on the
operator panel to access configuration settings and diagnostic tests via the
configuration menus. As you access menus and options, menu names and option
values appear on the operator panel message display (sometimes referred to as
LCD, or Liquid Crystal Display).
This chapter provides numerous examples of how to use the operator panel keys
and indicator message display to configure the printer.

Program Mode

The printer is in Program mode whenever the configuration menus and option
values are displayed on the operator panel message display. Program mode is
either locked or unlocked. In order to select new configuration values, you must
unlock Program mode. In order to prevent accidental changing of the configuration
settings, you may lock Program mode.

Unlocking The Program Mode

To use the operator panel to change the configuration settings, Program mode
must be unlocked. When Program mode is unlocked, pressing the Enter key selects
configuration values as the active values, that is, places them into printer DRAM.
An asterisk (*) after a displayed setting shows it is entered into memory.
Press the Return + Enter keys at the same time to unlock Program mode. The
following message will appear briefly:
