When you power on the printer,
the printer executes a
power-on self-test. The
message “Testing Hardware
Please Wait” displays. When
the self–test completes, the
message “Diagnostics Passed”
displays. Once the software
has initialized successfully, the
status indicator lights to
indicate the printer is online
and an online message
appears in the display, followed
by the name of the active
emulation (the default is LG).
If there is a fault during the
self-test, the status indicator
flashes and a specific fault
message appears on the
display (such as “LOAD
PAPER”). See page 64 for
information on Fault Messages.

The printer operates in one of three modes,
as described below:
•Online Mode — In online mode, the printer
can receive and print data sent from the
host. Pressing the ON LINE key toggles
the printer from offline to online mode. The
status indicator is lit in online mode.

configuration menus. Pressing the ON
LINE key toggles the printer from online to
offline mode. The status indicator is off in
offline mode.
•Fault Mode — a fault condition exists that
must be cleared before printing can
continue. In fault mode, the status indicator
is flashing, the alarm beeps three times,
and a descriptive fault message displays.
The current operating mode may be selected via
control panel keys, or may result from routine
operations such as powering on the printer. The
current operating mode is frequently indicated as
part of the printer display message.
