IBM 1800409-001A - Manual (Page 110)

The LCD Message Window
This message window presents status messages and Configuration
menu options. When you’re in the Configuration menu, the top line
of the message window displays the name of the current menu, and
the bottom line displays the name of an option within that menu.
Status messages display in order of priority if the printer is on line;
they don’t display if the printer is off line. Chapter 9,
“Troubleshooting,” lists and explains status messages.
Use the Clear Warning option to clear a status message that doesn’t
automatically clear after the related corrective action is taken. See
“Administration/Engine/Clear Warning,” later in this chapter, for
details.
The Control Panel LEDs
The LEDs (Light Emitting Diodes) on the control panel give
information about printer status:
Illuminated when the printer is on line, ready to accept
and process new print jobs.
Flashes when the printer is receiving data from one or
more of the simultaneous interfaces.
Illuminated when the printer requires operator
intervention.
Illuminated when the standard paper cassette is
selected.
Illuminated when the optional lower cassette is
selected.
