Operating Modes

Online - In online mode, the printer can receive and print data sent from the
host. Pressing the PAUSE key toggles the printer between the online and
offline mode. The ONLINE status indicator is lit in online mode.
Offline - In offline mode, you may perform operator functions, such as loading
media, or navigating through the printer configuration menu to make changes
or verify option settings. Pressing the PAUSE key toggles the printer from
offline to online mode. The ONLINE status indicator is not illuminated in offline
mode.
Fault - In fault mode, a fault condition exists that must be cleared before
printing can continue. The ONLINE status indicator flashes, the alarm beeps,
if configured to do so, and a descriptive fault message displays.
The current operating mode can be selected through the control panel keys,
or may result from routine operations such as powering on the printer.
