Chapter 2: A guided tour of the printer

2-4

The operator panel allows you to control the printer and change
settings. The indicator lamps show the current status of the printer.
The meaning and function of the buttons depends on the current
operating mode of the printer.

: The printer is switched on.

: An error is present which is preventing normal printing

operation (paper jam, end of paper).

: The printer is ready (ON LINE) to receive data from the com-

puter. If this lamp is not lit, the printer is in OFF LINE mode and not
ready to receive data. If the lamp is blinking, the printer is in print
suppress mode and is ignoring all data sent to it until this mode is
cancelled.

: The menu mode is activated. In this mode, you can alter

printer settings as you wish and permanently store these settings.
The menu mode is described in detail in Chapter 4. The MENU
lamp blinks if the temperature control mechanism has reduced the
printing speed in order to prevent overheating of the print head.
